Offer Highlights
The Company will acquire approximately 3,216 km[2] of largely contiguous, unencumbered 100%-owned tenure in the Lachlan Fold Belt ( LFB ) of New South Wales, a mineral province which hosts world-class, bulk tonnage and low cost porphyry gold-copper mining operations at both Cadia-Ridgeway and Northparkes , as well as potential new discoveries as evidenced by the recent Boda gold-copper drill results.
-
The Company has JORC-compliant mineral resources with an aggregate of 431,000 ounces of gold in three deposits[1] , all open in multiple directions, all with systematic resource drill-outs planned:
-
Mount Aubrey Epithermal Gold Project - located at the north margin of the Lachlan Transverse Zone ( LTZ ), covering multiple gold vein systems, three pits which were historically mined by BHP Gold to 40 metre free-dig depths in the 1990s.
-
Lewis Ponds Gold-Base Metal Project - located at the north margin of the LTZ, covering a continuous 65km strike of the major orogenic gold-hosting structure termed the Godolphin-Narragal Fault Zone (which hosts the McPhillamy’s gold deposit 15km south of Company tenure).
-
Yeoval Copper-Gold Project - located at the north margin of the LTZ, historic mineralised drill-holes require follow up.
-
Copper Hill East Gold-Copper Project , which is located at the eastern margin of the Boda-hosting Molong Volcanic Belt ( MVB ) south along the MVB structure from Boda and north from Cadia-Ridgeway. Soil geochemistry confirms anomalies associated with stockwork copper-veined monzonite intrusive.
-
Experienced board and management team with excellent credentials in the LFB.
-
Established operations base in Orange in the heart of the LFB.
-
Funds raised will be prioritised on direct project expenditure aimed at expanding known resources and making new discoveries. The Company intends to conduct up to 24,000 metres of reverse circulation drilling and up to 7,000 metres of diamond drilling over the next 24 months, noting however, that these intentions are subject to various factors outside of the Company’s control, including results from future drilling work, and may change without prior notice from the Company.

Letter from the Chairman
Dear Investor,
On behalf of the Directors, I look forward to welcoming you as a Shareholder of Godolphin Resources Limited ( Company ). The Company is gold and base metal focused with a clear strategy of fast-tracking the development of its projects in the Lachlan Fold Belt ( LFB ) of New South Wales, which includes 431,000 ounces of gold in JORC-compliant mineral resources[1] .
The Company's New South Wales assets are solely within the Lachlan Fold Belt in a largely contiguous land holding associated with structures hosting acknowledged world-class mines including Cadia-Ridgeway and Northparkes. Notably, the Company's eastern projects (Lewis Ponds, Copper Hill East, Ophir and Caledonian) are within the geological setting which hosts the new Boda porphyry gold-copper discovery announced by Alkane Resources Limited on 9 September 2019. The NSW Assets will comprise:
-
(a) Mount Aubrey Epithermal Gold Project - located at the north margin of the Lachlan Transverse Zone ( LTZ ), covering multiple gold-hosting epithermal vein systems, three of which were historically mined by BHP Gold to shallow depths in the 1990s, with high grade drill intercepts unmined beneath the pits.
-
(b) Copper Hill East Gold-Copper Project - located at the east margin of the Boda-hosting Molong Volcanic Belt ( MVB ), south along the MVB structure from Boda and north from Cadia-Ridgeway, with previous Company soil geochemistry confirming copper anomalies requiring drill testing.
-
(c) Lewis Ponds Gold-Base Metal Project - located at the north margin of the LTZ, covering a continuous 65km strike of the major orogenic gold-hosting structure termed the Godolphin-Narragal Fault, prospects from southeast to northwest are Lewis Ponds, Mt Bulga, Mt Lindsay, Ophir, Calula and Caledonian. The Lewis Ponds Gold Base Metal Project includes the underlying freehold land.
-
(d) Yeoval Porphyry Copper-Gold Project - located at the north margin of the LTZ, covering the Yeoval porphyry copper-gold-molybdenum-rhenium targets, with mineralisation open in all directions.
-
(e) Wiseman's Creek Gold-Silver Project - located within the central LTZ, epithermal gold-silver discovery by Ardea.
-
(f) Calarie Gold Project - located at the south margin of the LTZ, in the Parkes Fault Zone orogenic gold structure.
-
(g) Gundagai Gold Project - historic gold mines on the Cootamundra Fault with visible gold in quartz veins.
I lead an experienced, well-balanced Board of Directors and exploration team who have extensive skills in exploration and mine development, with expertise in the Lachlan Fold Belt.
The purpose of the Offers is to raise sufficient funds to facilitate resource definition and extension drilling, to be prioritised on the Mount Aubrey and Lewis Ponds gold resources, as well as for further exploration on the NSW Assets, including Copper Hill East. At the same time, as a condition of the Offers, we seek a listing of the Company on the ASX.
I encourage you to read this Prospectus, request that you consider the risks of investment in Section 3, and invite you to become a Shareholder in the Company, which I believe has great potential to further develop its Lachlan Fold Belt mineral resources. You should also note the Company’s intention to undertake a 1 for 3 Loyalty Option to be issued at no cost approximately three months after Admission.

Yours faithfully Mark Sykes Non-Executive Chairman Godolphin Resources Limited

| Topic | Summary | More information |
|---|---|---|
| Summary of key risks | ||
| Prospective investors should be aware that subscribing for Shares in the Company involves a number of risks. The risk factors set out in Section 3, and other general risks applicable to all investments in listed securities, may affect the value of the Shares in the future. Accordingly, an investment in the Company should be consideredhighly speculative. This Section summarises the key risks which apply to an investment in the Company and investors should refer to Section 3 for a more detailed summary of the risks. |
||
| Funding | At the date of this Prospectus, the Company has no income producing assets and will generate losses for the foreseeable future. Exploration success and favourable equity markets are required to maintain funding for high levels of activity after the initial two years following IPO. |
Section 3.1 |
| Commodity Prices | The Company's ability to proceed with the development of its mineral projects will depend on market factors, some of which may be beyond its control. It is anticipated that any revenues derived from mining will primarily be derived from the sale of gold and copper. |
Section 3.1 |
| Non-renewal of Title | A number of the Company's tenements are subject to application or renewal. There is a risk that the Company may not acquire or retain title to these Tenements. |
Section 3.1, 5 |
| Land-owner and Access Risk |
The Company will be required to negotiate access arrangements and pay compensation to land-owners, local authorities, traditional land users and others who may have an interest in the area covered by a mining tenement. The Company's ability to resolve access and compensation issues will have an impact on the future success and financial performance of the Company's operations. Legal processes are available in the case of disputes, but in preference Godolphin has made respectful and fair land-owner interactions an integral component of its operational strategy. A portion of the Wiseman's Creek tenement is Crown Land. Access to this land will be through the process of "right to negotiate". There are no current access agreements in place. |
Section 3.1, 5 |
| Management and Key Personnel |
The Company’s management consists of three non-executive Directors and a Chief Executive Officer. Should there be a resignation, there may be difficulties in recruiting similarly high-quality personnel. |
Section 3.1 |
| Limited Exploration | Other than Mount Aubrey, Lewis Ponds, Yeoval and Calarie, the Company’s projects have been subjected to only limited historic drill testing. Further exploration may fail to validate current targets. |
Section 2.3, 3.1, 4 |
| Resource Estimate | There is a degree of uncertainty to the estimation of Mineral Resources and Ore Reserves and corresponding grades being mined for future production. Estimates and viability can only be absolutely definitive at the sale of future marketable production. |
Section 3.1 |
| Venture Parties, Agents and Contractors |
The Company is unable to predict the risk of future financial failure or default by a participant in any future joint venture to which the Company may become a party (noting that the Company has no current joint venture intentions). |
Section 3.1 |
| Exploration, Development, Mining and Processing Risks |
The business of mineral exploration, project development and mining by its nature contains elements of significant risk including in relation to technical, financial, legal and social matters. |
Section 3.1, 4 |
Godolphin Resources Limited Prospectus - page 7
==> picture [595 x 66] intentionally omitted <==
| Topic | Summary | More information |
|---|---|---|
| Climate Change Risks | Climate change is a risk the Company has seriously considered, particularly related to its operations in the mining industry. The climate change risks particularly attributable to the Company include regulatory and weather conditions, or international responses or barriers due to Australian government policy. |
Section 3.1 |
| Environment | Godolphin will be required to rehabilitate land affected by exploration activities, and failure to do so may render the Tenements liable to cancellation. As has been the case under Ardea’s stewardship, it is Godolphin’s intention to conduct its activities to the highest standard of environmental obligation, including compliance with all environmental laws. |
Section 3.1,4 |
| Annual Rents and Levies | An annual rental and an administrative levy are payable, based on the size of the Tenements. Tenements are also subject to expenditure requirements. Failure to meet statutory requirements may result in loss of tenure. |
Section 3.1, 5 |
| Taxes and Royalties | There is a risk that the Commonwealth or New South Wales Governments may seek to introduce further, or increase existing, taxes and royalties. |
Section 3.1 |
| Economic Conditions | General economic conditions, introduction of tax reform, new legislation, movements in interest and inflation rates and currency exchange rates may have an adverse effect on the Company's exploration, development and production activities. |
Section 3.1 |
| Insurance Risk | The Company intends to put in place an insurance program aligned to the scale of its activities and in accordance with industry practice. The occurrence of an event that is not covered or fully covered by insurance could have a material adverse effect on the Company. |
Section 3.1 |
| Liquidity Risk | There can be no guarantee that there will be an active market for Shares or that the price of Shares will increase. |
Section 3.1 |
| Litigation Risk | The Company is subject to litigation risks. All industries, including the minerals exploration industry, are subject to legal claims, with and without merit. Defence and settlement costs of legal claims can be substantial, even with respect to claims that have no merit. |
Section 3.1. 5 |
| Native Title and Aboriginal Heritage Risks |
The Native Title Act 1993 (Cth) recognises and protects the rights and interests in Australia of Aboriginal and Torres Strait Islander people in land and waters, according to their traditional laws and customs. There is significant uncertainty associated with native title in Australia and this may impact on the Company’s operations and future plans. Tenements EL 8323 “Ophir” and EL 8538 “Yeoval” overlap with a registered native title claim. The grant of any future tenure to the Company over areas that are covered by registered claims or determinations will likely require engagement with the relevant claimants or native title holders (as relevant) in accordance with the Native Title Act. This engagement could cause delays to the Company’s plans and/or the Company may incur higher than anticipated costs. A number of the Company's tenements contain known Aboriginal heritage sites. The Company must also comply with Aboriginal heritage legislation requirements which require heritage survey work to be undertaken ahead of the commencement of exploration and mining operations. There are currently no Aboriginal heritage agreements or arrangements in place affecting the Tenements, though future negotiations are expected in the course of general exploration. |

| Exempted Areas | Under section 30 of the Mining Act the holder of an exploration licence must obtain the consent of the Minister before exploration activities may be conducted in an “exempted area”, which includes State Forests, State Conservation Areas and Crown Land. This currently applies to selected areas within Affects EL 8323 “Ophir”, EL 8554 “Wiseman’s Creek” and EL 8586 “Gundagai North”. Obtaining the consent of the Minister for exploration activities to be conducted in an “exempted area” will require environmental assessment of any proposed ground-disturbing exploration activities. |

Figure 3 The Godolphin-Narragal fault system (black), separating the Late Ordovician Molong Volcanic Belt of the Macquarie Arc (greens) from the younger, overlying, sedimentary-dominated Early Devonian sequences of the Hill End Trough (and its proximal portion, the Mumbil Shelf – purples).
These rocks, faults, and the mineralisation that they host are all overlain by the much younger Cenozoic rocks of the Canobolas Volcanic Centre (orange-brown) south of Orange.
The clear control of the fault system on mineralisation centre distributions has driven the acquisition and exploration of ground.

- (d) Loyalty Options
It is the Board’s current intention to offer Loyalty Options approximately 3 months after Admission. If issued, the Loyalty Options will be issued subject to a separate prospectus. Investors are not required to take any action to receive Loyalty Options.
1.11 Allocation and issue of Shares
Whilst priority will be given to Eligible Ardea Shareholders, the Directors will allocate Shares at their sole discretion in consultation with the Lead Manager with a view to ensuring an appropriate Shareholder base for the Company going forward and satisfying the ASX spread requirements. There is no assurance that any Applicant will be allocated any Shares, or the number of Shares for which it has applied.
The Directors reserve the right to reject any Application or to issue a lesser number of Shares than that applied for. If the number of Shares allocated is less than that applied for, or no allotment is made, any surplus Application Monies will be promptly refunded without interest.
Subject to the conditions of the Offer being met, the issue of Shares will occur as soon as practicable after the Offers close and after completion of the In-specie Distribution. Holding statements will be despatched as required by ASX. It is the responsibility of applicants to determine their allocation prior to trading in the Shares.
Applicants who sell the Shares before they receive their holding statement will do so at their own risk.
1.12 Application Monies to be held in trust
Application Monies will be held in a separate bank account on behalf of applicants until the Shares are issued. If the Shares to be issued under this Prospectus are not admitted to quotation within a period of three months from the date of this Prospectus, the Company will either repay the Application Monies (without interest) to Applicants or issue a supplementary prospectus or replacement prospectus and allow Applicants one month to withdraw their Applications and have their Application Monies refunded to them (without interest).
1.13 Escrow arrangements & ASX In-Principle Waiver
ASX will classify certain existing Shares on issue in the Company (as opposed to those to be issued under this Prospectus) as being subject to the restricted securities provisions of the Listing Rules. These Shares would be required to be held in escrow for up to 24 months and would not be able to be sold, mortgaged, pledged, assigned or transferred for that period without the prior approval of ASX. During the period in which these Shares are prohibited from being transferred, trading in Shares may be less liquid which may impact on the ability of a Shareholder to dispose of their Shares in a timely manner.
The Shares offered under the General Offer and Ardea Offer will not be subject to any escrow restrictions.
The Company has applied for and been granted an in-principle waiver ( In-principle Waiver ) from ASX that the Consideration Shares being distributed Ardea Shareholders will not be subject to escrow. The In-Principle Waiver sets out that ASX would be likely to grant a formal waiver subject to the:
-
(a) Ardea Shareholders approving the In-specie Distribution prior to the Company making an application to list on ASX; and
-
(b) the Company prominently disclosing a summary of the In-principle Waiver in the Prospectus.
Godolphin Resources Limited Prospectus - page 24
==> picture [595 x 66] intentionally omitted <==
As at the date of this Prospectus the Company expects approximately:
-
(a) 3,457,656 Shares (being Shares acquired by Ardea directors pursuant to the In-specie Distribution);
-
(b) 15,000,000 Consideration Options, to be issued to Ardea;
-
(c) 2,000,000 Employee Options to be issued to employees of the Company, including the CEO;
-
(d) 1,000,000 Incentive Options to be issued to Directors;
-
(e) 2,000,000 Advisor Options; and
-
(f) 100 Shares held by Ardea already on issue at the date of the Prospectus,
to be subject to the 24 months escrow.
1.14 CHESS and issuer sponsorship
The Company will apply to participate in CHESS. All trading on the ASX will be settled through CHESS. ASX Settlement, a wholly-owned subsidiary of the ASX, operates CHESS in accordance with the Listing Rules and the ASX Settlement Operating Rules. On behalf of the Company, the Share Registry will operate an electronic issuer sponsored subregister and an electronic CHESS sub-register. The two sub-registers together make up the Company's principal register of securities.
Under CHESS, the Company will not issue certificates to Shareholders. Rather, holding statements (similar to bank statements) will be sent to Shareholders as soon as practicable after allotment. Holding statements will be sent either by CHESS (for Shareholders who elect to hold Shares on the CHESS sub-register) or by the Company's Share Registry (for Shareholders who elect to hold their Shares on the issuer sponsored sub-register). The statements will set out the number of existing Shares (where applicable) and the number of new Shares allotted under this Prospectus and provide details of a Shareholder's holder identification number (for Shareholders who elect to hold Shares on the CHESS subregister) or Shareholder reference number (for Shareholders who elect to hold their Shares on the issuer sponsored sub-register). Updated holding statements will also be sent to each Shareholder at the end of each month in which there is a transaction on their holding, as required by the Listing Rules.

2. Overview of the Company
2.1 Company history
The Company was incorporated on 19 June 2019 and, other than as disclosed in this Prospectus, has not undertaken any activities since incorporation. As at the date of this Prospectus, the Company is a wholly-owned subsidiary of Ardea.
On 3 October 2019, the Company and GTPL entered into a demerger implementation deed with Ardea, TriAusMin and AEPL ( DID ) to acquire the NSW Assets (including the Tenements and TriAusMin). Under the DID, the Company also made an offer of employment to certain Ardea employees. The effect of the DID is that the Company will, subject to satisfaction of the conditions precedent, acquire the NSW Assets for 30,000,000 Shares at a deemed issue price of $0.20 per Share ( Consideration Shares ) and 15,000,000 Options ( Consideration Options ). See Section 6.2 for further information on the DID.
2.2 Corporate structure
Upon listing, the Company's corporate structure will be as set out in the following diagram:

TriAusMin is a 100% owned subsidiary of Ardea and forms part of the consolidated Ardea Group. TriAusMin holds tenements and freehold land, and will have no other assets or liabilities when it is transferred to the Company.
GTPL was incorporated on 26 June 2019 and has no material assets or liabilities.
From Admission, the Company will hold its exploration assets in GTPL and TriAusMin, and believes this is an appropriate corporate structure for an exploration and development company aiming to progress towards production.
2.3 Project Summary
The Company's corporate strategy is to explore and develop its large, contiguous tenement land holding within the Lachlan Fold Belt, a leading Australian province for bulk tonnage, low operating cost gold-base metal mines such as the Cadia-Ridgeway gold-copper mine, Northparkes copper-gold mine and Cowal gold mine. This strategy has been validated by Alkane Resources Limited's ( Alkane ) ASX announcement on 9 September 2019 of its Boda porphyry gold-copper discovery.
All of the Tenements were applied for in 2016 to 2019 on the basis of known mineralisation, underpinned by the Company's subsequent JORC-compliant resource estimates, which comprise in aggregate 431,000 ounces of gold[1] , as set out below and in the Independent Technical Assessment in Schedule 5.
The Company is in a unique position of being a Lachlan Fold Belt junior explorer with significant JORC-compliant mineral resources.
1 Please see page 5, 7, 8 and 9 of the Independent Technical Assessment for a breakdown of resource categories, grades and tonnages.
Godolphin Resources Limited Prospectus - page 27
==> picture [595 x 66] intentionally omitted <==
(a) Mount Aubrey Epithermal Gold Project
Mount Aubrey was acquired by Ardea as a quartz vein stockwork gold system. Gold mineralisation is typically hosted by 0.5–3m thick chalcedonic epithermal quartz veins and stockworks. The site was mined via three shallow open pit gold-mines by BHP Gold in 1990 and 1991. Based on observed quartz vein textures, including diagnostic carbonate replacement, Mount Aubrey is an epithermal system which has implications for vein zoning and continuity at depth. Additionally, the observed high gold grades are typically “epithermal”, with unmined intercepts below the base of the pits including 7 metres at 16.48 g/t gold and 4 metres at 22.75 g/t gold.
| Resource Category | Cut-off | Tonnes | Au | Contained gold |
|---|---|---|---|---|
| Aug/t | (Mt) | (g/t) | (oz) | |
| Inferred | ≥0.50 | 1.21 | 1.61 | 62,400 |
A Competent Person Statement is included in respect of the resource estimate in Section 2.4. Information required by Listing Rule 5.8.1 and 5.8.2 is contained in the Independent Technical Assessment in Schedule 5.
(b) Copper Hill East Gold-Copper Project
The Copper Hill East Gold-Copper Project occurs within the east margin of the Molong Volcanic Belt. On 9 September 2019, Alkane[1] announced that its drill intercept at Boda in the MVB demonstrates “clear evidence of Cadia-style mineralisation and grade over hundreds of metres.” The northern MVB, within the eastern Lachlan Fold Belt “is considered highly prospective for large porphyry gold-copper mineralisation, as demonstrated by the presence of the world class Cadia Valley porphyry district located 110km to the south (~49Moz Au; Newcrest website)”. Alkane detailed “a zonation pattern of outer propylitic and sodic alteration from the top of hole vectoring to a copper rich outer calc-potassic core (biotite + chlorite + chalcopyrite ± kspar ± magnetite ± bornite mineral assemblage). The style of alteration and mineralisation has several apparent similarities with the upper sections of the Cadia East Deposit (2,900Mt @ 0.36g/t gold, 0.26% Cu, Newcrest Mining Limited global resource Annual Report 2018)”.[1] Identification of potassic alteration has been a core focus of the Company in all of its on-ground exploration and will remain a focus as the Company further explores its model at the Copper Hill East Gold-Copper Project within the eastern MVB contact.
(c) Lewis Ponds Gold-Base Metal Project
The Lewis Ponds group of projects covers a 65km strike length of the highly prospective Godolphin-Narragal Fault Zone, which significantly, hosts orogenic shear-hosted gold deposits including the McPhillamy’s deposit some 15km south of Lewis Ponds and Commonwealth deposit some 100km north. Exploration has historically been on the basis of a narrow high-grade underground mining model. Godolphin has reinterpreted the project as a bulk tonnage open pit model and has generated an indicated and inferred mineral resource totalling 20.24Mt at 0.5g/t Au, 33.3g/t Ag, 1.5% Zn, 0.7% Pb and 0.1% Cu.
The breakdown for the full Lewis Ponds resource categories is as follows:
| Resource Cut-off Tonnes Au Ag Zn Pb Cu Category (ZnEq%) (Mt) (g/t) (g/t) (%) (%) (%) |
|
|---|---|
| Open Pit Indicated 1 7.88 0.3 26.3 1.1 0.4 0.1 Inferred 1 6.51 0.5 27.4 1.3 0.6 0.1 |

(d) Yeoval Porphyry Copper-Gold Project
Yeoval is located within the Macquarie Arc, 60km northeast of the Northparkes copper-gold mine. The tenement covers an area of 138km[2] and is intensely mineralised with more than 60 historic copper workings trending in a north-easterly direction along a 20km strike. The exploration concept is a large tonnage porphyry copper-goldmolybdenum-rhenium system. Yeoval has an Inferred Mineral Resource as follows:
| Resource Category | Tonnes | Cu | Au | Ag | Molybdenum |
|---|---|---|---|---|---|
| (Mt) | (%) | (g/t) | (g/t) | (g/t) | |
| Inferred | 12.8 | 0.38 | 0.14 | 2.20 | 120 |
A Competent Person Statement is included in respect of the resource estimate in Section 2.4. Information required by Listing Rule 5.8.1 and 5.8.2 is contained in the Independent Technical Assessment in Schedule 5.
(e) Wiseman's Creek Gold-Silver Project
Wiseman’s Creek is located 35km southeast of Bathurst, NSW, around the logging town of Oberon. Epithermal gold mineralisation within the tenure is hosted largely within Late Silurian to Early Devonian-aged sediments, with geology through the centre of the tenure comprising the andesitic Ordovician-aged Rockley Volcanics (equivalent units host the Cadia and Northparkes gold-copper operations).
(f) Calarie Gold Project
Calarie is associated with the highly mineralised Macquarie Arc Ordovician andesites (Parkes Volcanics) some 5-30km SSW of Parkes within the strongly gold-endowed Parkes Fault Zone.
(g) Gundagai Gold Project
The Gundagai tenements are located 315km southwest of Sydney. Several old gold workings hosted by mineralised porphyry units exist in the Company tenure, with historic RC drilling at Big Ben returning up to 20 metres at 1.58g/t gold within a quartz-limonite-pyrolusite stockworks system (as first announced to ASX in the Ardea prospectus dated 9 November 2016).

Mr Lambrechts is a full time employee of Ardea Resources Limited and will become a full time employee of the Company on Admission, and has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Resources. Mr Lambrechts consents to the inclusion in the report of the matter based on his information in the form and context in which it appears.
2.5 Business strategy / objectives
Godolphin views the LFB as the premium province in Australia in which to find and develop bulk tonnage gold-base metal deposits, with Cadia-Ridgeway, Northparkes and Cowal evidencing the province’s production potential. The region’s exploration potential is further evidenced by McPhillamy's gold discovery (Regis Resources Limited) and now the spectacular Boda porphyry gold-copper discovery hole (Alkane Resources Limited).
Having settled on the LFB as a favoured exploration province, Ardea systematically set about building the vehicle to deliver shareholder value. Since its admission to the Official List, Ardea has:

(a) compiled available historic data notably drilling into geographic information systems to build up a data base that emphasises the controls on mineralisation, notably crustal-scale structures such as the LTZ, Godolphin-Narragal Fault, Gilmore Suture and Boda-hosting Molong Volcanic Belt;
-
(b) recruited an exceptional exploration team in Orange, the heart of the LFB; and
-
(c) incorporated Godolphin as the corporate vehicle to explore then develop the identified targets.
The Company's strategy has three well-defined activities for application to the selected targets:
-
(a) Work towards production
-
(i) Mount Aubrey Gold - complete the drill-out of the known gold-silver resource, then undertake feasibility programs ahead of financial studies to ascertain if it’s economic to mine and if so, determine the optimum development strategy.
-
(ii) Lewis Ponds – complete core drilling of the defined mineralisation, focussing on interpreted gold-enriched zones, then undertake metallurgical studies ahead of feasibility programs.
-
(b) Exploration
-
(i) Gold-Copper Project – further refinement of the “Boda-Ridgeway porphyry gold-copper potassic alteration” concept through the development of exploration models and drill testing.
-
(ii) All other tenure - complete the Company’s standard multi-element soil geochemistry on defined targets to elucidate drill testing requirements.
-
(c) Corporate
-
(i) Evaluate mergers and acquisitions that potentially strengthen the Company’s future production base.
-
(ii) Farm-out tenure that doesn’t meet corporate objectives.
-
(iii) Continue to lodge tenement applications on vacant ground that supports the Company’s mineralisation models.
The Company does not expect to pay dividends in the near future as its focus will primarily be on developing the Mount Aubrey and Lewis Ponds projects.
Any future determination as to the payment of dividends by the Company will be at the discretion of the Directors and will depend upon matters such as the availability of distributable earnings, the operating results and financial condition of the Company, future capital requirements, general business and other factors considered relevant by the Directors. No assurances are given in relation to the payment of dividends.

3. Risk Factors
As with any share investment, there are risks involved. This Section identifies the major areas of risk associated with an investment in the Company, but should not be taken as an exhaustive list of the risk factors to which the Company and its Shareholders are exposed. Potential investors should read the entire Prospectus and consult their professional advisers before deciding whether to apply for Shares.
Any investment in the Company under this Prospectus should be considered highly speculative.
3.1 Risks specific to the Company
(a) Funding
At the date of this Prospectus, the Company has no income producing assets and will generate losses for the foreseeable future. Until it is able to develop a project and generate appropriate cashflow, it is dependent upon being able to obtain future equity or debt funding to support long term exploration, after the expenditure of the net proceeds raised under the Offers. Neither the Company nor any of the Directors nor any other party can provide any guarantee or assurance that if further funding is required, such funding can be raised on terms acceptable to the Company.
Any additional equity funding will dilute existing Shareholders. Also, no guarantee or assurance can be given as to when a project can be developed to the stage where it will generate positive cashflow. As such, a project would be dependent on many factors, for example exploration success, subsequent mine development, commissioning and operational performance.
Should it choose in future to enter joint ventures, the Company may not be able to earn or maintain proposed equity interests in its tenements if it fails to meet the ongoing expenditure commitments. Accordingly, the Company may potentially lose entitlement or rights to interests in tenements and projects where ongoing expenditure commitments are not met.
(b) Commodity prices
The Company's ability to proceed with the development of its mineral projects and benefit from any future mining operations will depend on market factors, some of which may be beyond its control. It is anticipated that any revenues derived from mining will primarily be derived from the sale of gold and copper. Consequently, any future earnings are likely to be closely related to the price of these commodities and the terms of any off-take agreements that the Company enters into.
Commodity prices fluctuate and are affected by numerous factors beyond the control of the Company. These factors include worldwide and regional supply and demand for the specific commodity, prevailing commodity trading terms, general world economic conditions and the outlook for interest rates, inflation and other economic factors on both a regional and global basis. These factors may have a positive or negative effect on the Company’s exploration, project development and production plans and activities, together with the ability to fund those plans and activities. Furthermore, some products are not traded upon terminal, liquid, commodity exchanges. There is a risk therefore that the Company may not be able to secure an attractive price for its commodity products.
(c) Non-renewal of title and new applications
A number of the Company's tenements are subject to application or renewal, the details of which are set out in the Solicitor's Report in Schedule 4. There is a risk that the Company may not acquire or retain title to these Tenements.
Under New South Wales law, exploration tenements are valid for set periods of time and renewal is subject to the approval of the State Minister. There is no guarantee that the Company will be successful in the renewal of exploration tenements as they reach their expiry date, though statutory mechanisms exist to extend title.
If in future tenements are not extended, the Company may suffer damage through loss of the opportunity to discover and/or develop any mineral resources on these tenements.
Godolphin Resources Limited Prospectus - page 31
==> picture [595 x 66] intentionally omitted <==
(d) Land-owner and access Risk
The Company will be required to negotiate access arrangements and pay compensation to land owners, local authorities, traditional land users and others who may have an interest in the area covered by a mining tenement. The Company's ability to resolve access and compensation issues will have an impact on the future success and financial performance of the Company's operations. If the Company is unable to resolve such compensation claims on economic terms, this could have a material adverse effect on the business, results or operations and financial condition of the Company. Access to land for exploration purposes can be affected by land ownership, nature reserves and national parks, government regulation and environmental restrictions. Access is critical for exploration and development to succeed and the ability to be able to negotiate satisfactory commercial arrangements with landowners, farmers and occupiers is often essential.
Further a portion of the Wiseman's Creek tenement is Crown Land. Access to this land will be through the process of "right to negotiate". There are no current access agreements in place.
(e) Management and Key Personnel
The Company’s management presently consists of three non-executive Directors and a Chief Executive Officer.
Recruiting and retaining qualified personnel are important to the Company's success. The number of persons skilled in the exploration and development of mining properties is limited and competition for such persons is strong. There can be no assurance given that there will be no detrimental impact on the Company if one or more key employees leave the Company.
(f) Limited exploration
Other than Mount Aubrey, Lewis Ponds, Yeoval, Calarie and Gundagai (see Section 2.3), the Company’s projects have been subjected to only limited historic drill testing. Whilst gold and/or base metal mineralisation, as the case may be, has been located in multiple previous drill intersections, there is a risk that the mineralisation in adjacent drill holes is not continuous between drill holes. There is also a risk that the previously completed drill holes may not be representative of the overall mineralisation present. Further drill tests are required to determine if mineralisation extends further beyond the geometry as defined in current drill patterns.
To the extent that further exploration extends the Company's current resource estimates, there is no guarantee that the Company will be capable of sustaining commercial development.
(g) Resource estimate
There is a degree of uncertainty to the estimation of Mineral Resources and Ore Reserves and corresponding grades being mined or dedicated to future production. Until Mineral Resources or Ore Reserves are actually mined and processed, the quantity of Mineral Resources and Ore Reserves must be considered as estimates only. In addition, the grade of Mineral Resources and Ore Reserves may vary depending on, among other things, metal prices. Any material change in quantity and grades of Mineral Resources, Ore Reserves, or stripping ratio may affect the economic viability of the properties. In addition, there can be no assurance that metal recoveries in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.
Fluctuation in the prices of relevant commodities, results of drilling, metallurgical testing and the evaluation of mine plans subsequent to the date of any estimate may require revision of such estimate. Any material reductions in estimates of Mineral Resources and / or Ore Reserves, could have a material adverse effect on Company's financial condition.
(h) Joint Venture Parties, Agents and Contractors
The Company is unable to predict the risk of financial failure or default by a participant in any future joint venture to which the Company may become a party (noting that the Company has no current joint venture intentions). Further, the Company is unable to predict the risk of insolvency or managerial failure by any of the contractors used by the Company in any of its activities or the insolvency or other managerial failure by any of the other service providers used by the Company for any activity. The effects of such failures may have an adverse effect on the Company's operations.
Godolphin Resources Limited Prospectus - page 32
==> picture [595 x 66] intentionally omitted <==
(i) Exploration, Development, Mining and Processing Risks
The business of mineral exploration, project development and mining by its nature contains elements of significant risk. Ultimate and continuous success of these activities is dependent on many factors such as:
-
(i) geological conditions;
-
(ii) the discovery and/or acquisition of economically recoverable ore reserves;
-
(iii) successful conclusions to feasibility studies;
-
(iv) alterations to programs and budgets;
-
(v) access to adequate capital for project development;
-
(vi) design and construction of efficient mining and processing facilities within capital expenditure budgets;
-
(vii) securing and maintaining title and access to tenements and compliance with the terms of those tenements;
-
(viii) industrial action, disputation or disruptions;
-
(ix) unavailability of transport or drilling equipment to allow access and geological and geophysical investigations;
-
(x) obtaining consents and approvals necessary for the conduct of exploration and mining; and
-
(xi) access to competent operational management and prudent financial administration, including the availability and reliability of appropriately skilled and experienced employees, contractors and consultants.
Adverse weather conditions over a prolonged period can adversely affect exploration and mining operations and the timing of revenues.
Whether or not income will result from projects undergoing exploration and development programs depends on the successful establishment of mining operations. Factors including costs, integrity of mineralisation, consistency and reliability of ore grades and commodity prices affect successful project development and mining operations.
(j) Climate change risks
Climate change is a risk the Company has considered, particularly related to its operations in the mining industry. The climate change risks particularly attributable to the Company include:
-
(i) the emergence of new or expanded regulations associated with the transitioning to a lower-carbon economy and market changes related to climate change mitigation. The Company may be impacted by changes to local or international compliance regulations related to climate change mitigation efforts, or by specific taxation or penalties for carbon emissions or environmental damage. These examples sit amongst an array of possible restraints on industry that may further impact the Company and its profitability. While the Company will endeavour to manage these risks and limit any consequential impacts, there can be no guarantee that the Company will not be impacted by these occurrences; and
-
(ii) climate change may cause certain physical and environmental risks that cannot be predicted by the Company, including events such as increased severity of weather patterns and incidence of extreme weather events and longer-term physical risks such as shifting climate patterns. All these risks associated with climate change may significantly change the industry in which the Company operates.
(k) Environment
As a condition of the Tenements, the Company will be required to rehabilitate, level, re-grass, reafforest or contour land that has been damaged or adversely affected by exploration activities, failure to do so may render the Tenements liable to cancellation. Godolphin is also required to lodge rehabilitation security by way of cash deposit.
It is the Company’s intention to continue to conduct its activities to the highest standard of environmental obligation, including compliance with all environmental laws.
(l) Annual Rents and Levies
An annual rental and an administrative levy are payable, based on the size of the Tenements. Tenements are also subject to expenditure requirements in accordance with work programs approved by the NSW Department of Planning and Environment. Payment of rentals and levies are currently up to date. Failure to comply with future expenditure requirements may render the Tenements liable to cancellation.
Godolphin Resources Limited Prospectus - page 33
==> picture [595 x 66] intentionally omitted <==
(m) Taxes and Royalties
Tenement holders must pay royalties to the NSW government on minerals (including material containing minerals) obtained from a mining tenement. Royalties are payable quarterly and must be accompanied by a royalty return in the approved form. The holder of a mining tenement must provide a quarterly production report commencing at the expiration of the first quarter during which any mineral is produced or obtained from that mining tenement.
Royalty rates for group 1 minerals, comprising metallic minerals, are generally 4% of the value of the mineral recovered. There is a risk that the Commonwealth or New South Wales Governments may seek to introduce further, or increase existing, taxes and royalties.
(n) Unforeseen Risks
There may be other risks which the Directors are unaware of at the time of issuing this Prospectus which may impact on the Company and its operations, and on the valuation and performance of the Company’s Shares.
(o) Economic conditions
General economic conditions, introduction of tax reform, new legislation, movements in interest and inflation rates and currency exchange rates may have an adverse effect on the Company's exploration, development and production activities, as well as on its ability to fund those activities. If activities cannot be funded, there is a risk that the tenements comprising the NSW Assets may have to be surrendered or not renewed. General economic conditions may also affect the value of the Company's Shares and its valuation regardless of its actual performance.
(p) Insurance risk
The Company intends to put in place an insurance program aligned to the scale of its activities and in accordance with industry practice. The occurrence of an event that is not covered or fully covered by insurance could have a material adverse effect on the business, financial condition and results of the Company.
(q) Liquidity risk
There can be no guarantee that there will be an active market for Shares or that the price of Shares will increase. There may be relatively few buyers or sellers of Shares on ASX at any given time. This may affect the volatility of the market price of Shares. It may also affect the prevailing market price at which Shareholders are able to sell their Shares. This may result in Shareholders receiving a market price for their Shares that is less or more than the price paid under the Offers.
(r) Litigation risk
The Company is subject to litigation risks. All industries, including the minerals exploration industry, are subject to legal claims, with and without merit. Defence and settlement costs of legal claims can be substantial, even with respect to claims that have no merit.
Due to the inherent uncertainty of the litigation process, the resolution of any particular legal proceeding to which the Company is or may become subject could have a material effect on its financial position, results of operations or the Company's activities.
Godolphin Resources Limited Prospectus - page 34
==> picture [595 x 66] intentionally omitted <==
(s) Native Title and Aboriginal Heritage Risks
The Native Title Act 1993 (Cth) recognises and protects the rights and interests in Australia of Aboriginal and Torres Strait Islander people in land and waters, according to their traditional laws and customs. There is significant uncertainty associated with native title in Australia and this may impact on the Company’s operations and future plans.
Native title can be extinguished by valid grants of land or waters to people other than the native title holders or by valid use of land or waters. It can also be extinguished if the indigenous group has lost their connection with the relevant land or waters. Native title is not extinguished by the grant of mining leases, as they are not considered to be grants of exclusive possession. A valid mining lease prevails over native title to the extent of any inconsistency for the duration of the title.
Tenements EL 8323 “Ophir” and EL 8538 “Yeoval” overlap with a registered native title claim. The grant of any future tenure to the Company over areas that are covered by registered claims or determinations will likely require engagement with the relevant claimants or native title holders (as relevant) in accordance with the Native Title Act. This engagement could cause delays to the Company’s plans and/or the Company may incur higher than anticipated costs.
For tenements to be validly granted (or renewed) after 23 December 1996 the special “right to negotiate” regime established by the Native Title Act must be followed.
It is important to note that the existence of a native title claim is not an indication that native title in fact exists to the land covered by the claim, as this is a matter ultimately determined by the Federal Court.
A number of the Tenements contain known Aboriginal heritage sites. The Company must also comply with Aboriginal heritage legislation requirements which require heritage survey work to be undertaken ahead of the commencement of exploration and mining operations and may require heritage agreements to be entered into prior to work being undertaken. There is a risk that the negotiation of these agreements could cause delay to the Company’s plans.
There are currently no Aboriginal heritage agreements or arrangements in place affecting the Tenements, though future negotiations are expected in the course of general exploration. There remains a risk that additional Aboriginal sites may exist on the land the subject of the Tenements. The existence of such sites may preclude or limit mining activities in certain areas of the Tenements.
(t) Exempted Areas
Under section 30 of the Mining Act the holder of an exploration licence must obtain the consent of the Minister before exploration activities may be conducted in an “exempted area”, which includes State Forests, State Conservation Areas and Crown Land. This currently applies to selected areas within Affects EL 8323 “Ophir”, EL 8554 “Wiseman’s Creek” and EL 8586 “Gundagai North”.
Obtaining the consent of the Minister for exploration activities to be conducted in an “exempted area” will require environmental assessment of any proposed ground-disturbing exploration activities. The assessment will be undertaken by the NSW Department of Planning and Environment in consultation with the relevant government department. It would also be expected that such consent would only be granted or denied in consultation with the relevant government department and, if granted, subject to the terms of an access agreement reached with that department in addition to any owner or occupier access agreement. For further information, please see the Solicitor's Report at Schedule 4.
(u) Competing Tenement Application
The Yeoval South exploration licence application (ELA 5780) is the subject of a competing tenement application. There is a risk that the area granted by the NSW Department of Planning and Energy will be significantly less than the 253 units applied for.
(v) Social Licence
In order to explore, develop or operate in communities, the general acceptance of certain stakeholder populations may be required. This may include formal agreements that can require extended negotiations with large numbers of stakeholders, for example indigenous communities and groups with native title rights. There can be no guarantee these negotiations will be concluded successfully or not be protracted and cause significant delay to the Company's plans.
Godolphin Resources Limited Prospectus - page 35

(w) Stock market conditions
Share market conditions may affect the listed securities regardless of operating performance. Share market conditions are affected by many factors such as:
-
(i) general economic outlook;
-
(ii) movements in or outlook on interest rates and inflation rates;
-
(iii) currency fluctuations;
-
(iv) commodity prices;
-
(v) changes in investor sentiment towards particular market sectors; and
-
(vi) the demand and supply for capital.
(x) Negative publicity may adversely affect the Share price
Any negative publicity or announcement relating to any of the Company's substantial Shareholders, key personnel or activities may adversely affect the stock performance of the Company, whether or not this is justifiable. Examples of such negative publicity or announcements may include involvement in legal or insolvency proceedings, failed attempts in takeovers, joint ventures or other business transactions. No such issues are currently known to affect the Company.
3.2 Investment speculative
The above list of risk factors ought not to be taken as exhaustive of the risks faced by the Company or by prospective investors in the Company. The above factors, and others not specifically referred to above, may in the future materially affect the financial performance of the Company and the value of the Shares offered under this Prospectus.
Therefore, the Shares issued pursuant to the Offers carry no guarantee with respect to the payment of dividends, returns of capital or the market value of those Shares.
Potential investors should consider that the investment in the Company is highly speculative and should consult their professional advisers before deciding whether to apply for Shares.

4. Financial information
4.1 Financial information
The Investigating Accountant's Report contained in Schedule 3 sets out the pro-forma statement of financial position for the Company as at 30 June 2019.
Investors are urged to read the Investigating Accountant's Report in full.
4.2 Forecast financial information
There are significant uncertainties associated with forecasting future revenues and expenses of the Company. In light of uncertainty as to timing and outcome of the Company's growth strategies and the general nature of the industry in which the Company will operate, as well as uncertain macro market and economic conditions in the Company's markets, the Company's performance in any future period cannot be reliably estimated. On these bases and after considering ASIC Regulatory Guide 170, the Directors do not believe they have a reasonable basis to reliably forecast future earnings and accordingly forecast financials are not included in this Prospectus.

The Board has adopted a formal Board Charter that details the Board's role, authority, responsibilities, membership and operations, and will be available on our website at www.godolphinresources.com.au.
The Charter sets out the matters specifically reserved for the Board and the powers delegated to any of its Committees and to the Managing Director.
The Board delegates responsibility for the day-to-day management of Godolphin to the Chief Executive Officer, but retains responsibility for the overall strategy, governance and performance of the Company.
In general, the Board assumes (among others) the following responsibilities:
-
(i) setting the direction, strategies and financial objectives of Godolphin and ensuring appropriate resources are available;
-
(ii) overseeing management's implementation of the Company's strategic objectives and its performance generally;
-
(iii) monitoring compliance with control and accountability systems, regulatory requirements and ethical standards;
-

(b) Composition of the Board
Election of Board members is substantially the province of the Shareholders in general meeting. Upon Listing, the Board will be comprised of the Chief Executive Officer and three Non-Executive Directors. From the commencement of Listing, the Board shall at all times have at least three members, a majority of whom shall be independent Directors. As the Company's activities develop in size, nature and scope, the composition of the Board and the implementation of additional corporate governance policies and structures will be reviewed.
(c) Identification and management of risk
The Board's collective experience will assist in the identification of the principal risks that may affect the Company's business. Key operational risks and their management will be recurring items for deliberation at Board meetings.
(d) Ethical standards
The Board is committed to the establishment and maintenance of appropriate ethical standards.
(e) Independent professional advice
Subject to the Chairman's approval (not to be unreasonably withheld), the Directors, at the Company's expense, may obtain independent professional advice on issues arising in the course of their duties.
(f) Remuneration arrangements
The remuneration of any executive director will be decided by the Board, without the affected executive director participating in that decision-making process.
In addition, subject to any necessary Shareholder approval, a Director may be paid fees or other amounts as the Directors determine where a Director performs special duties or otherwise performs services outside the scope of the ordinary duties of a Director (e.g. non-cash performance incentives such as options).
Subject to any necessary shareholder approval and the Corporations Act, the Board may offer Directors Shares in lieu of Directors' fees upon such terms and conditions as the Board determines.
Directors are also entitled to be paid reasonable travel and other expenses incurred by them in the course of the performance of their duties as Directors.
The Board reviews and approves the Company's remuneration policy in order to ensure that the Company is able to attract and retain executives and Directors who will create value for Shareholders, having regard to the amount considered to be commensurate for an entity of the Company's size and level of activity as well as the relevant Directors' time, commitment and responsibility.
The Board is also responsible for reviewing any employee incentive and equity-based plans including the appropriateness of performance hurdles and total payments proposed.
(g) Securities trading policy
The Board has adopted a policy that sets out the guidelines on the sale and purchase of securities in the Company by its directors, employees, contractors and consultants. The policy generally provides that the written acknowledgement of the Chairman (or the Board in the case of the Chairman) must be obtained prior to trading.
(h) Audit and risk
The Company will not have a separate audit or risk committee until such time as the Board is of a sufficient size and structure, and the Company's operations are of a sufficient magnitude for a separate committee to be of benefit to the Company. In the meantime, the full Board will carry out the duties that would ordinarily be assigned to that committee under the written terms of reference for that committee, including but not limited to, monitoring and reviewing any matters of significance affecting financial reporting and compliance, the integrity of the financial reporting of the Company, the Company's internal financial control system and risk management systems and the external audit function.
(i) External audit
The Company in general meetings is responsible for the appointment of the external auditors of the Company, and the Board from time to time will review the scope, performance and fees of those external auditors.

The policy outlines requirements for compliance with confidentiality, governance, legal, privacy and regulatory parameters when using social media to conduct Company business.
(k) Whistleblower policy
The Board has adopted a whistleblower protection policy to ensure concerns regarding unacceptable conduct including breaches of the Company's code of conduct can be raised on a confidential basis, without fear of reprisal, dismissal or discriminatory treatment. The purpose of this policy is to promote responsible whistle blowing about issues where the interests of others, including the public, or of the organisation itself are at risk.

An invitation may specify that at the time of exercise of the Convertible Securities, the Participant may elect not to be required to provide payment of the exercise price for the number of Convertible Securities specified in a notice of exercise, but that on exercise of those Convertible Securities the Company will transfer or issue to the Participant that number of Shares equal in value to the positive difference between the Market Value of the Shares at the time of exercise and the exercise price that would otherwise be payable to exercise those Convertible Securities.
'Market Value' means, at any given date, the volume weighted average price per Share traded on the ASX over the 5 trading days immediately preceding that given date, unless otherwise specified in an invitation.
A Convertible Security may not be exercised unless and until that Convertible Security has vested in accordance with the Plan rules, or such earlier date as set out in the Plan rules.
-
(i) ( Delivery of Shares on exercise of Convertible Securities ): As soon as practicable after the valid exercise of a Convertible Security by a Participant, the Company will issue or cause to be transferred to that Participant the number of Shares to which the Participant is entitled under the Plan rules and issue a substitute certificate for any remaining unexercised Convertible Securities held by that Participant.
-
(j) ( Forfeiture of Convertible Securities ): Where a Participant who holds Convertible Securities ceases to be an Eligible Participant or becomes insolvent, all unvested Convertible Securities will automatically be forfeited by the Participant, unless the Board otherwise determines in its discretion to permit some or all of the Convertible Securities to vest. Where the Board determines that a Participant has acted fraudulently or dishonestly, or wilfully breached his or her duties to the Group, the Board may in its discretion deem all unvested Convertible Securities held by that Participant to have been forfeited.
Unless the Board otherwise determines, or as otherwise set out in the Plan rules:
-
(i) any Convertible Securities which have not yet vested will be forfeited immediately on the date that the Board determines (acting reasonably and in good faith) that any applicable vesting conditions have not been met or cannot be met by the relevant date; and
-
(ii) any Convertible Securities which have not yet vested will be automatically forfeited on the expiry date specified in the invitation.
-
(k) ( Change of control ): If a change of control event occurs in relation to the Company, or the Board determines that such an event is likely to occur, the Board may in its discretion determine the manner in which any or all of the Participant's Convertible Securities will be dealt with, including, without limitation, in a manner that allows the Participant to participate in and/or benefit from any transaction arising from or in connection with the change of control event.

-
(l) ( Rights attaching to Plan Shares ): All Shares issued under the Plan, or issued or transferred to a Participant upon the valid exercise of a Convertible Security, ( Plan Shares ) will rank pari passu in all respects with the Shares of the same class. A Participant will be entitled to any dividends declared and distributed by the Company on the Plan Shares and may participate in any dividend reinvestment plan operated by the Company in respect of Plan Shares. A Participant may exercise any voting rights attaching to Plan Shares.
-
(m) ( Disposal restrictions on Plan Shares ): If the invitation provides that any Plan Shares are subject to any restrictions as to the disposal or other dealing by a Participant for a period, the Board may implement any procedure it deems appropriate to ensure the compliance by the Participant with this restriction.
For so long as a Plan Share is subject to any disposal restrictions under the Plan, the Participant will not:
-
(i) transfer, encumber or otherwise dispose of, or have a security interest granted over that Plan Share; or
-
(ii) take any action or permit another person to take any action to remove or circumvent the disposal restrictions without the express written consent of the Company.
-
(n) ( Adjustment of Convertible Securities ): If there is a reorganisation of the issued share capital of the Company (including any subdivision, consolidation, reduction, return or cancellation of such issued capital of the Company), the rights of each Participant holding Convertible Securities will be changed to the extent necessary to comply with the Listing Rules applicable to a reorganisation of capital at the time of the reorganisation. If Shares are issued by the Company by way of bonus issue (other than an issue in lieu of dividends or by way of dividend reinvestment), the holder of Convertible Securities is entitled, upon exercise of the Convertible Securities, to receive an allotment of as many additional Shares as would have been issued to the holder if the holder held Shares equal in number to the Shares in respect of which the Convertible Securities are exercised. Unless otherwise determined by the Board, a holder of Convertible Securities does not have the right to participate in a pro rata issue of Shares made by the Company or sell renounceable rights.
-
(o) ( Participation in new issues ): There are no participation rights or entitlements inherent in the Convertible Securities and holders are not entitled to participate in any new issue of Shares of the Company during the currency of the Convertible Securities without exercising the Convertible Securities.
-
(p) ( Amendment of Plan ): Subject to the following paragraph, the Board may at any time amend any provisions of the Plan rules, including (without limitation) the terms and conditions upon which any Securities have been granted under the Plan and determine that any amendments to the Plan rules be given retrospective effect, immediate effect or future effect. No amendment to any provision of the Plan rules may be made if the amendment materially reduces the rights of any Participant as they existed before the date of the amendment, other than an amendment introduced primarily for the purpose of complying with legislation or to correct manifest error or mistake, amongst other things, or is agreed to in writing by all Participants.
-
(q) ( Plan duration ): The Plan continues in operation until the Board decides to end it. The Board may from time to time suspend the operation of the Plan for a fixed period or indefinitely, and may end any suspension. If the Plan is terminated or suspended for any reason, that termination or suspension must not prejudice the accrued rights of the Participants. If a Participant and the Company (acting by the Board) agree in writing that some or all of the Securities granted to that Participant are to be cancelled on a specified date or on the occurrence of a particular event, then those Securities may be cancelled in the manner agreed between the Company and the Participant.
Directors, including non-executive Directors, are able to participate in the Plan.

This report has been prepared to provide investors with information on the Pro Forma Financial Information as detailed in the scope below. The Pro Forma Financial Information is presented in Appendix 1 of this report and does not include all of the disclosures required by Australian Accounting Standards, Australian Accounting Interpretations and other authoritative pronouncements of the Australian Accounting Standards Board.
This report does not address any rights attached to the Shares to be issued in accordance with the Prospectus, nor the risks associated with the investment and has been prepared based on the Offers being achieved.
We have not been requested to consider the prospects for the Company, the shares on offer and related pricing issues, nor the merits and risks associated with becoming a shareholder and accordingly, have not done so. Accordingly, we take no responsibility for these matters or for any matter or omission in the Prospectus, other than responsibility for this report.
Background
The Company was registered by its current parent company Ardea Resources Limited (“Ardea”) on 25 June 2019 following a strategic review by the Ardea board of its assets and a decision by the Ardea board to dispose of its New South Wales assets into the Company.
Subject to Ardea shareholder approval and satisfaction of various other conditions, the Company will acquire the New South Wales assets and Ardea will distribute approximately 30,000,000 New Shares to its shareholders.
The Prospectus invites potential investors to apply for up to 40,000,000 shares at a subscription price of $0.20 each to raise up to $8,000,000 (before costs), the public General Offer. The Company is also offering Eligible Ardea Shareholders the opportunity to subscribe for Shares through a priority offer, the Ardea Offer.
Godolphin Resources Limited Prospectus - page 63
==> picture [595 x 66] intentionally omitted <==
The Offers comprise the General Offer and the Ardea Offer (together, “the Offers”) and remain conditional on the Company raising the Minimum Subscription under the Offers being $4,500,000.
Following a successful Offer, the Company will become the parent entity of a group of three companies including Godolphin Tenements Pty Ltd and TriAusMin Pty Ltd.
Godolphin Tenements Pty Ltd was registered by its current parent company Ardea on 25 June 2019 and has been dormant since registration.
TriAusMin Pty Ltd was registered on 21 October 1993 and is currently audited as part of the Ardea Group of companies. Since the company was acquired by Ardea in February 2017 the company has not been operational and merely held tenements as part of the Ardea group.
Scope of review of Pro Forma Financial Information
You have requested us to prepare an Investigating Accountant’s Report covering the reviewed Pro Forma Statements of Financial Position as at 30 June 2019 adjusted for the effects of the Offers and material events occurring subsequent to 30 June 2019.
The reviewed Pro Forma Financial Information set out in Appendix 1 of this report has been compiled based on historical financial information extracted from the financial statements of Ardea Resources Limited as at 30 June 2019 and the transactions relating to the Offers.
The extracted historical financial information relates to those assets and liabilities being acquired by the Company as a result of an asset disposal from Ardea.
The Pro Forma Statements of Financial Position incorporate the proposed transactions as detailed in Appendix 2 of this report.
Directors’ responsibility
The Directors are responsible for the preparation and presentation of the Pro Forma Financial Information, including determination of the Pro Forma adjustments. This includes responsibility for such internal controls as the directors determine are necessary to enable the preparation of Pro Forma Financial Information that is free from material misstatement, whether due to fraud or error.
Our responsibility
Our responsibility is to express a limited assurance conclusion on the Pro Forma Financial Information based on the procedures performed and the evidence we have obtained.
We have conducted our engagement in accordance with the Standard on Assurance Engagements ASAE 3450 “Assurance Engagements Involving Corporate Fundraisings and/or Prospective Financial Information”.
A review consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.
We made such enquiries and performed such procedures as we in our professional judgement considered reasonable in the circumstances including:
-
Enquiry of Directors, management and others;
-
Review of the assumptions used to compile the Pro Forma Financial Information;
-
Review of available financial information; and
-
Review of work papers, accounting records and other documents.
A review is substantially less in scope than an audit conducted in accordance with Australian Auditing Standards and consequently does not enable us to obtain reasonable assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the Pro Forma Financial Information
Based on our review, which is not an audit, nothing has come to our attention which causes us to believe that the Pro Forma Financial Information, as set out in Appendix 1 of this report:
-
a) Does not fairly represent the Pro Forma Statements of Financial Position adjusted for the effects of the Offers and material events occurring subsequent to 30 June 2019;
-
b) Has not been prepared in accordance with the measurement and recognition requirements (but not all of the disclosure requirements) prescribed in Australian Accounting Standards, Australian Accounting Interpretations and other authoritative pronouncements of the Australian Accounting Standards Board.
Subsequent events
Apart from the matters dealt with in this report, and having regard to the scope of our report, to the best of our knowledge and belief no material transactions or events outside of the ordinary business of the Company have come to our attention that would require comment on, or adjustment to the information referred to in our report or that would cause such information to be misleading or deceptive.
Other matters including independence
Butler Settineri (Audit) Pty Ltd and I do not have any interest in the outcome of this issue other than in its capacity as Investigating Accountant for which normal professional fees will be received. Butler Settineri (Audit) Pty Ltd and I do not hold nor have an interest in the ordinary shares of the Company.
Butler Settineri (Audit) Pty Ltd and I were not involved in the preparation of any other part of the Prospectus, and accordingly, make no representations or warranties as to the completeness and accuracy of any information contained in any other part of the Prospectus.
Butler Settineri (Audit) Pty Ltd and I consent to the inclusion of this report in the Prospectus in the form and context in which it is included. At the date of this report, this consent has not been withdrawn.
Yours faithfully

INVESTIGATING ACCOUNTANT’S REPORT
APPENDIX 1 PRO FORMA STATEMENTS OF FINANCIAL POSITION
1 Statement of significant accounting policies
Statement of Compliance
The Pro Forma Financial Information has been prepared in accordance with the measurement requirements, but not the disclosure requirements, of the Australian Accounting Standards.
Basis of Preparation
Going concern
The financial information has been prepared on a going concern basis which contemplates the continuity of normal business activities and the realisation of assets and discharge of liabilities in the ordinary course of business. The Company has not yet generated revenues from operations. As such, the Company’s ability to continue as a going concern will depend on the successful closure of the Offers.
Accounting policies
The financial information has been prepared on an accruals basis and is based on historical costs, except for certain financial instruments measured at fair value.
The following is a summary of the material accounting policies adopted by the Company in the preparation of the financial information.
(a) Cash and cash equivalents
Cash and cash equivalents includes cash on hand, deposits held at call with financial institutions, other short-term highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to insignificant risk of changes in value.
(b) Exploration and evaluation expenditure assets
Costs arising from the acquisition of exploration and evaluation activities are carried forward where these activities have not, at reporting date, reached a stage to allow a reasonable assessment regarding the existence of economically recoverable reserves. The ultimate recoupment of costs carried forward for exploration and evaluation phases is dependent on the successful development and commercial exploitation or sale of the respective areas of interest. Ongoing exploration activities are expensed as incurred.
Exploration and evaluation assets shall be assessed for impairment when facts and circumstances suggest that the carrying amount of an exploration and evaluation asset may exceed its recoverable amount, in particular when exploration for and evaluation of mineral resource in the specific area have not led to the discovery of commercially viable quantities of mineral resources and the company has decided to discontinue such activities in the specific area.
(c) Property, plant and equipment
Items of property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditure that is directly attributable to the acquisition of the asset and costs directly attributable to bringing the asset to a working condition for their intended use.
(d) Trade and other payables
Trade and other payables are initially recognised at fair value and subsequently measured at amortised cost when the company becomes obliged to make payments resulting from the purchase of goods and services. The amounts are non-interest-bearing, unsecured and are usually paid within 30 days of recognition.

INVESTIGATING ACCOUNTANT’S REPORT
APPENDIX 1 PRO FORMA STATEMENTS OF FINANCIAL POSITION
1 Statement of significant accounting policies (cont’d)
(e) Contributed equity
Ordinary shares are classified as equity. Costs directly attributable to the issue of new shares or options are shown as a deduction from the equity proceeds, net of any income tax benefit recognised.
(f) Critical accounting estimates and judgements
The Directors evaluate estimates and judgements incorporated into the financial information based on historical knowledge and best available current information. Estimates assume a reasonable expectation of future events and are based on current trends and economic data, obtained internally and externally.
(g) Share-based payments
The fair value of options granted is recognised as an expense with a corresponding increase in equity. The fair value is measured at grant date and recognised over the period during which the option holder become unconditionally entitled to the options.
The fair value of the options at grant date is independently determined using the Black-Scholes option pricing model that takes into account the exercise price, the term of the option, the impact of dilution, the share price at grant date and expected price volatility of the underlying share, the expected dividend yield and the risk-free interest rate for the term of the option.
The fair value of the options granted is adjusted to reflect market vesting conditions, but excludes the impact of any non-market vesting conditions (for example, profitability and sales growth targets). Non-market vesting conditions are included in assumptions about the number of options that are expected to become exercisable. At each reporting date, the entity revises its estimate of the number of options that are expected to become exercisable. The employee benefit expense recognised each period takes into account the most recent estimate. The impact of the revision to original estimates, if any, is recognised in the consolidated statement of comprehensive income with a corresponding adjustment to equity.
The fair value of these equity instruments does not necessarily relate to the actual value that may be received in future by the recipients.

The loan was provided by Ardea Resources Limited and represents costs incurred by Ardea for the benefit of Godolphin from 1 June 2019 in relation to rent, rates and exploration costs on Tenements, any Duty payable on the transfer of the Tenements or the Lewis Ponds Freehold Land to Godolphin, wages, adviser and legal expenses associated with the In-Specie Distribution, Internal Restructure and General Offer (“the Offers”).

| Tenements acquired from Ardea Resources Ltd | 7,413 | 7,413 |
| Total | 7,413 | 7,413 |
The value of the tenements to be acquired by the Company is based on the accumulated historical acquisition and exploration costs incurred by Ardea in respect of the New South Wales tenements.
There has been no impairment of these historical costs recorded as Ardea has maintained ownership of the underlying tenements, exploration activity has been ongoing and has not yet reached the stage which enables a reasonable assessment as to the existence or otherwise of economically recoverable reserves. This treatment is in accordance with the Company’s accounting policy.

| Subscription | Subscription | |

| Trade and other payables | - | - |
Total listing and listing related costs expected to be incurred in the General Offer of the Company are $305K and its operating costs and exploration costs from 30 June 2019 to the date of listing are expected to be $721K, leaving a total to be paid from proceeds of $1,026K at the date of listing.
In addition to this the Lead Manager will be paid a fee of 1% on the total proceeds from the new equity and a 5% underwriting fee on all third party funds received.
In the pro-forma the repayments are deemed to have been paid to Ardea following the receipt of funds from the proceeds of the General Offer.
If only the minimum of $4.5M is raised then the total cash repayment will be capped at $500K with an additional $200K paid in fully paid ordinary shares at the 20 cent subscription price. If more than the minimum $4.5M is raised then the repayments will be on a sliding scale based on 12.5% of funds raised up to the maximum of $1M. If the loan is greater than $1M, then up to an additional $200K will be paid in fully paid ordinary shares at the 20 cent subscription price.
In each case the balance of funds payable will be written off by Ardea limiting the payments for the Company and ensuring a minimum cash position of $4M at the time of listing.

Dear Sirs
SOLICITOR’S REPORT ON NSW TENEMENTS
1. INTRODUCTION
This report is prepared for inclusion in a prospectus ( Prospectus ) to be dated on or about 28 October 2019 for issue by Godolphin Resources Limited (ACN 633 779 950) ( Godolphin Resources) for an Offer of up to 40,000,000 Shares at a price of $0.20 each to raise up to $8,000,000. The minimum subscription is 22,500,000 Shares at an issue price of $0.20 each to raise a total of $4,500,000.
The report relates to the mining tenements ( Tenements ) in which Godolphin Resources’ wholly owned subsidiary Godolphin Tenements Pty Ltd (ACN 634 219 999) ( Godolphin Tenements or Company ) is the transferee under transfers to be lodged with the NSW Department of Planning and Environment ( DPE ), or are held by TriAusMin Pty Ltd ( TriAusMin ), which will become a wholly owned subsidiary Godolphin Resources.
The above transfers will be lodged upon all conditions precedent of a Demerger Implementation Deed ( DID ) dated 3 October 2019 being met or waived, notably receipt of a conditional admission letter from ASX in relation to the proposed listing of Godolphin Resources. The DID was entered into between Godolphin Resources and Godolphin Tenements (together Godolphin ), TriAusMin and Ardea Resources Limited ( Ardea Resources ) and Ardea Exploration Pty Ltd ( Ardea Exploration , together Ardea ).
All of the Tenements are located in New South Wales ( NSW ). The attached Tenement Schedule ( Schedule ) and notes to the Schedule contain an overview of the Tenements.
Ardea holds a 100% interest in all of the Tenements. There are encumbrances registered against a number of the Tenements, noted in the Schedule.
2. OPINION
Based on our searches and enquiries, and subject to the assumptions and qualifications set out below, we confirm at the date of the searches that:
-
(a) the details of the Tenements referred to in the Schedule are accurate as to the status and registered holder of the Tenements;
-
(b) unless otherwise specified in this report, the Tenements are in good standing, and all applicable rents and levies have been paid;
-
(c) there are encumbrances or dealings registered against a number of the Tenements;
-
(d) none of the Tenements are subject to any unusual conditions of a material nature other than as disclosed in the Schedule; and
Godolphin Resources Limited Prospectus - page 72
==> picture [595 x 66] intentionally omitted <==
- (e) subject to the comments below relating to standard administrative authorisations, which are normally applied for at the time of finalising the details of individual exploration programs, or as otherwise detailed in this Prospectus, there are no legal, regulatory or contractual impediments to the Company undertaking the proposed exploration on the Tenements as detailed elsewhere in the Prospectus.
3. SEARCHES
For the purpose of this report, we have obtained and reviewed:
-
(a) searches of the Tenements in the mining tenement register ( Register ) maintained by the Division of Resources and Geoscience of the NSW Department of Planning and Environment ( DPE ) under the Mining Act 1992 (NSW) ( Mining Act ) and Mining Regulation 2016 (NSW) ( Mining Regulation ) conducted on 19 October 2019;
-
(b) summary searches of the NSW Tenements on the ‘MinView’ online system maintained by the DPE conducted on 18 October 2019;
-
(c) searches of the native title register maintained by the National Native Title Tribunal on 18 October 2019; and
-
(d) searches of the Aboriginal Heritage Information Management System maintained by the Office of Environment and Heritage (NSW) on 17 June 2019.
4. ASSUMPTIONS AND QUALIFICATIONS
In preparing this report:
-
(a) we have assumed the accuracy and completeness of results of the searches of the registers maintained by the various government agencies;
-
(b) we have been advised that there are no contracts, agreements or arrangements entered into by Ardea relating to the Tenements, except for the finder’s fee agreement for Lewis Ponds (see Note 6 of the Schedule);
-
(c) where any agreement, dealing or act (including disturbing the land for exploration) affecting the Tenements requires an authorisation, approval, permission or consent ( Authorisation ) under the Mining Act, or any other relevant legislation, we have assumed that Authorisation has been or will be granted in due course;
-
(d) where any dealing in the Tenements has been lodged for registration but is not yet registered, we express no opinion as to whether the registration will be effected, or the consequences of non-registration;
-
(e) we have assumed and been advised by Ardea that the relevant title holder has complied with all applicable provisions of the Mining Act and all other legislation relating to the Tenements; and
-
(f) we have not researched the underlying land tenure in respect of the Tenements to determine if:
-
(i) native title rights have or have not been extinguished, or the extent of any extinguishment; or
-
(ii) the Tenements encroach on any private land in which the rights to minerals have been reserved to the owner of the land.
5. TENEMENT SCHEDULE
The Tenements comprise 12 exploration licences (prefix EL ) and one mining lease (prefix ML ) granted under the Mining Act, and three applications for exploration licences (prefix ELA ) to be granted under the Mining Act. The ELs are for Group 1 Minerals, comprising metallic minerals. ML 7039 “Calarie” is for gold, silver and platinum.
The Schedule sets out a brief description of the Tenements and a summary of any encumbrances.
In relation to the area of each Tenement specified in the Schedule:
-
(a) the area is described by units, given by one minute of latitude by one minute of longitude on the earth’s surface. In the general location of the Tenements each unit is approximately 2.9 square km. Areas given in square km are therefore approximate only. It is not possible to verify those areas without conducting a survey; and
-
(b) the area might be reduced by a number of exclusions, including the existence of mining leases, National Parks or reserves situated within the boundaries of the relevant Tenement.
Godolphin Resources Limited Prospectus - page 73

6. BACKGROUND ON EXPLORATION LICENCES AND APPLICATIONS IN NSW
(a) Rights of a holder of an EL
The rights of a holder of an EL are subject to compliance by that holder with the provisions of the Mining Act and the terms and conditions of the licence.
An EL gives the holder the exclusive right to explore for minerals over a specific area of land. The holder of an EL may, in accordance with the conditions of the EL and subject to the Mining Act, conduct exploration activities on the land specified in the EL for the group of minerals specified in the licence.
An EL does not permit mining, and an EL holder will not necessarily be permitted to mine in the future if a discovery is made.
(b) Rights of an applicant for an ELA
The DPE will not register a transfer of an ELA, but there is no restriction on an applicant selling an application and providing for the registration of the transfer upon grant.
(c) Term and transfer
An EL may be granted for up to six years, and may be extended by successive periods of up to six years, on application by the holder. However, ELs are generally granted and renewed for periods of three years, depending on the proposed work program and other factors. An EL may be transferred to another person upon approval by the Minister for Energy and Environment ( Minister ). In approving a transfer, the Minister may impose amended or additional conditions on the holder of the EL.
(d) Renewal
An EL will not usually be renewed over more than half the number of units comprising the original EL unless the Minister is satisfied that special circumstances exist, including that the conditions of the licence have been satisfactorily complied with, the full area of the EL has been effectively explored, and the proposed work program satisfactorily covers the full area to be renewed.
Provided the conditions of the Tenements continue to be met, we do not see any reason why the Minister would not grant a renewal of all of the units comprising the Tenements for further periods of three years.
(e) Conditions
Each of the ELs are subject to standard conditions that must be complied with, including expenditure to meet the annual proposed work program, payment of government fees, and the requirement to lodge annual technical reports. Standard conditions also stipulate that a tenement holder obtain the consent of an officer of the DPE prior to conducting any ground disturbing work, and include basic environmental and rehabilitation conditions, such as the removal of all waste and capping of drill holes..
The Minister’s approval is required for a change of effective control of a licence holder. There is an exemption if the change of control occurs as a result of the acquisition of shares on a registered stock exchange. To the best of Resources Legal’s knowledge, there is no reason why the Minister’s approval will not be granted in due course.
Holders must also comply with the Exploration Codes of Practice, including the Environmental Management Code, the Rehabilitation Code, which requires the holder to rehabilitate, level, re-grass, reforest or contour land that has been damaged or adversely affected by exploration activities, and the Community Consultation Code. A Review of Environmental Factors and an Agricultural Impact Statement may be required for surface-disturbing exploration activities such as drilling.
Failure by the holder of an EL to comply with these conditions may render the EL liable to cancellation.
(f) Access agreements
Prior to commencing exploration activities on private land, an access agreement must be entered into with the owner or occupier of the land[1] . Compensation is payable for any loss or damage caused by the activities[2] .
There are no current access agreements in place.

2 Section 263 Mining Act 1992 (NSW)
Godolphin Resources Limited Prospectus - page 74
==> picture [595 x 66] intentionally omitted <==
(g) Exempted areas
Under section 30 of the Mining Act the holder of an EL must obtain the consent of the Minister before exploration activities may be conducted in an “exempted area”, which includes State Forests, State Conservation Areas and Crown Land. This currently applies to selected areas within Affects EL 8323 “Ophir”, EL 8554 “Wiseman’s Creek” and EL8586 “Gundagai North”.
Obtaining the consent of the Minister for exploration activities to be conducted in an “exempted area” will require environmental assessment of any proposed ground-disturbing exploration activities. The assessment will be undertaken by the DPE in consultation with the relevant government department. It would also be expected that such consent would only be granted or denied in consultation with the relevant government department and, if granted, subject to the terms of an access agreement reached with that department in addition to any owner or occupier access agreement described in section 6(f) of this report.
(h) Annual rents and levies
An annual rental and an administrative levy are payable, based on the size of the EL. ELs are also subject to expenditure requirements in accordance with work programs approved by the DPE. These rental, levy and expenditure requirements are set out in the Schedule. Payment of rentals and levies are currently up to date. Failure to comply with expenditure requirements may render the EL liable to cancellation.
7. BACKGROUND ON MINING LEASES IN NSW
(a) Rights of a holder of a ML
The rights of a holder of a ML are subject to compliance by that holder with the provisions of the Mining Act and the terms and conditions of the lease.
A ML gives the holder the exclusive right to mine minerals from a specific area of land. The holder of a ML may, in accordance with the conditions of the ML and subject to the Mining Act, conduct mining operations on the land specified in the ML for the group of minerals specified in the lease.
Applicants must demonstrate that there is an economically mineable mineral deposit within the area of the proposed ML, and they have the financial and technical resources to carry out mining in a responsible manner. A development consent under the Environmental Planning and Assessment Act 1979 must be in place before a mining lease can be granted. A work program must be submitted, which details the proposed mining operations, community consultation, environmental management and rehabilitation.
(b) Term and transfer
A ML remains in force for a maximum period of 21 years or such longer period as may be determined by the Minister. An ML may be transferred to another person upon approval by the Minister. In approving a transfer, the Minister may impose amended or additional conditions on the holder of the ML.
(c) Conditions
The Minister’s approval is required for a change of effective control of a lease holder. There is an exemption if the change of control occurs as a result of the acquisition of shares on a registered stock exchange. To the best of Resources Legal’s knowledge, there is no reason why the Minister’s approval will not be granted in due course.
Failure by the holder of an ML to comply with these conditions may render the ML liable to cancellation.
(d) Annual rents and levies
An annual rental and an administrative levy are payable, based on the size of the ML. MLs are also subject to minimum annual expenditure/work requirements which are set out in the Schedule. A failure to comply with expenditure requirements may render the ML liable to cancellation.

8. ENVIRONMENTAL AND PLANNING LEGISLATION
Tenement holders may also be required to obtain approvals under and comply with environmental and planning and other legislation, including:
-
(i) Environmental and Planning Assessment Act 1979 (NSW);
-
(ii) Protection of the Environment Operations Act 1997 (NSW); and
-
(iii) Water Act 1912 and Water Management Act 2000 (NSW).
9. ROYALTIES
Tenement holders must pay royalties to the NSW government on minerals (including material containing minerals) obtained from a mining tenement. Royalties are payable quarterly and must be accompanied by a royalty return in the approved form. The holder of a mining tenement must provide a quarterly production report commencing at the expiration of the first quarter during which any mineral is produced or obtained from that mining tenement.
Royalty rates for Group 1 Minerals, comprising metallic minerals, are generally 4% of the value of the mineral recovered[3] .
10. REHABILITATION SECURITIES
The holder of a Tenement is required to lodge with the DPE a security by way of a cash deposit or banker's undertaking for the performance of its rehabilitation and other obligations arising under the Tenement. The security for each of the Tenements is $10,000, with the exception of EL 5583 “Lewis Ponds“, which is $40,000, and ML 739 “Calarie”, which is $22,000.
11. NATIVE TITLE
(a) Background
Native title or claims for native title exist over parts of NSW.
The existence of a lodged claim does not necessarily mean that native title exists over the area claimed, nor does the absence of a claim necessarily indicate that no native title exists in an area. The existence of native title will be established under the determination of claims by the Federal Court.
The grant of a mining tenement is a ‘Future Act’ for the purposes of the Native Title Act 1993 (Cth) ( NTA )[4] . A Future Act is an activity or development on land or waters that affects native title. Native title claimants gain the “right to negotiate” in relation to the grant of certain mining tenements if their native title claim is registered at the time the government issues a notice, known as a section 29 notice, stating it intends to do the act, in this case grant the mining tenement, or if their claim becomes registered within four months after that notice.
(b) Right to negotiate
The right to negotiate applies in the main to the grant of a mining lease and describes a process whereby the tenement applicant and native title claimant must negotiate in good faith to attempt to resolve any potential concerns the native title claimants may have arising from the mining lease application or its grant. If the parties cannot reach agreement as to the terms of grant, a negotiation party may apply to the National Native Title Tribunal ( NNTT ) to make a determination as to whether the grant may proceed (and if so, on what conditions).
The right to negotiate process does not necessarily have to be followed in locations where an Indigenous Land Use Agreement ( ILUA ) has been negotiated with the relevant Aboriginal people and registered with the NNTT. In such cases the procedures set out in the ILUA must be followed for the ML to be granted.
(c) Searches
Searches conducted in the register maintained by the NNTT on 18 October 2019 showed that two Tenements, ELs 8323 “Ophir” and 8538 “Yeoval” overlap with a registered native title claim. The right to negotiate process has commenced in respect of EL 8323 “Ophir”.

(d) Effect of native title on the Tenements
ELs are generally subject to a condition that requires the holder to obtain the Minister’s consent before carrying out exploration activity on land where native title has not been extinguished. Ministerial consent will only be granted after the right to negotiate process has been followed, or the land on which native title has not been extinguished has been excised from the EL. The grant of a mining lease over land where native title has not been extinguished is also subject to the right to negotiate process.
The DPE has published guidelines on the evidence required to demonstrate extinguishment of native title. Native title has been wholly extinguished over much of NSW, including through the grant of freehold estates, leases in perpetuity for grazing purposes under the Western Lands Act 1901 , and the establishment of public works.
(e) Compensation
The Mining Act makes mining tenement holders liable for any native title compensation that may be payable as a result of the grant of the mining tenemen[5] . If the existence of native title is proven over any of the land subject to the Tenements, and the native title holders make an application to the Federal Court for compensation, the Tenement holder may be liable to pay any compensation awarded.
12. ABORIGINAL HERITAGE
(a) Commonwealth
The Aboriginal and Torres Strait Islander Heritage Protection Act 1984 (Cth) ( Commonwealth Heritage Act ) is aimed at the preservation and protection of any Aboriginal areas and objects that may be located on the Tenements.
Under the Commonwealth Heritage Act, the Minister for Aboriginal Affairs may make interim or permanent declarations of preservation in relation to significant Aboriginal areas or objects, which can affect exploration activities. Compensation is payable by the Minister to a person who is, or is likely to be, affected by a permanent declaration of preservation.
(b) New South Wales
Under the National Parks and Wildlife Act 1974 (NSW) ( NSW Heritage Act ), land containing Aboriginal objects or sites may be reserved as an “Aboriginal area” for the purpose of identifying, protecting and conserving such objects or sites. It is unlawful to prospect or mine for minerals in an Aboriginal area unless expressly authorised by an Act of Parliament or, among other things, an authority issued under the Mining Act. Subject to this exception, the NSW Heritage Act excludes the application of the Mining Act to lands in an Aboriginal area.
The NSW Heritage Act also authorises the Minister to declare a place that is or was of special significance to Aboriginal culture to be an ‘Aboriginal place’ and makes it an offence knowingly to destroy, deface or damage, or knowingly to permit the destruction, defacement of or damage to, an Aboriginal object or “Aboriginal place” without the consent of the Director-General.
(c) Heritage surveys
To satisfy the obligations under the relevant Heritage Act, tenement holders commonly undertake Aboriginal heritage surveys, which involve the relevant traditional owners and as necessary, an archeologist or anthropologist walking the land, identifying sites and discussing the impact of proposed exploration activity. The costs of a heritage survey are met by the tenement holder.
(d) Heritage searches
We obtained and reviewed searches of the Aboriginal Heritage Information Management System maintained by the Office of Environment and Heritage (NSW) on 17 June 2019. The searches showed that the Tenements contain a number of known Aboriginal sites. The Company will review the location of each site when planning its exploration programs so as to ensure that activities near Aboriginal sites meet the requirements of the Commonwealth Heritage Act and the NSW Heritage Act.
There are currently no Aboriginal heritage agreements or arrangements in place affecting the Tenements, however terms have been agreed in respect of EL 8323 “Ophir”, which provide for compensation payments and for heritage surveys to be conducted by the Native Title applicants prior to ground disturbing activities being conducted.

Notes
- AEPL = Ardea Exploration Pty Ltd. At the date of this report AEPL, Godolphin Resources and Godolphin Tenements are wholly owned subsidiaries of Ardea Resources Limited (ASX:ARL).
TRI = TriAusMin Pty Ltd, a wholly owned subsidiary of ARL.
-
One unit is the area bounded by one minute of latitude by one minute of longitude and, depending on the location in NSW, comprises an area of approximately 2.9 square kilometres. As shown on the tenement maps contained in the Prospectus, portions have been excised from some of the units in the licences.
-
Schedule 9 of the Mining Regulation sets out tenement rentals and levies. The annual rental is $60 per unit for ELs and $6.50 per hectare for MLs. The annual administrative levy is 1% of the security deposit (1% of $10,000 = $100 for most tenements). The EL renewal application fee is $2,000 plus $12.50 per unit per year applied for, eg renewal fee for 100 unit EL for three years is $2,000 plus $37.50 x 100 = $5,750. For a ML the renewal application fee is $3,000 plus $36 per hectare.
-
Proposed expenditure in the current year of the licence term, to be met through current exploration work programs approved by the DPE. For example, EL 5583 “Lewis Ponds” requires an expenditure of $81,000 in the 12 months to June 2020. Work may include geological mapping, rock chip sampling, soil geochemical surveys, geophysical surveys, modelling of results, drilling and core logging.
-
Calarie: The current Mine Operations Plan for ML 739 provides only for exploration, and care and maintenance activities. Dealings and encumbrances include a Farm-in Agreement, however the farminee, Kimberley Diamonds Ltd, has withdrawn from its farm-in to Calarie.
-
Lewis Ponds: A portion of EL 5583, comprising former EL 1049 consisting of 2.56km[2] ( Property ), is subject to a finder’s fee, payable to geologist David Timms, following commencement of production, or sale of the Property, capped at A$2 million. The fee is based on 1/3 of proceeds from sale of the Property, or 1/3 of net profits from production, or 30% of any royalties received from production, from the Property.
-
Ophir: Dealings and encumbrances include miscellaneous approvals, exempted area operations and native title right to negotiate (see section 11(c) of this report).
-
Wisemans Creek: Dealings and encumbrances include exempted area operations.
-
Yeoval South: The DPE has advised there is a competing tenement application; the area to be offered is likely to be significantly less than 253 units.

1. Executive Summary
Cube Consulting Pty Ltd (“Cube”) has been commissioned by Godolphin Resources Ltd (“Godolphin”) to provide an Independent Technical Assessment Report (“ITAR”) on the Godolphin New South Wales (“NSW”) tenements for the purposes of the proposed listing of Godolphin on the Australian Securities Exchange (“ASX”) during 2019. Cube understands the ITAR or abridged version thereof will form part of a prospectus for an Initial Public Offering (“IPO”). Godolphin has proposed that the IPO will raise a minimum of A$4.5M, up to a maximum of A$8M.
The purpose of this Report is to provide an independent technical assessment for inclusion in a prospectus to be issued by Godolphin to support the proposed listing on the ASX.
This Report does not provide a valuation of the mineral assets and has been prepared to the standard of, and is considered by Cube to be, a Technical Assessment Report in accordance with the Code and Guidelines for Assessment and Valuation of Mineral Assets and Mineral Securities for Independent Expert Reports (“VALMIN Code”). The VALMIN Code is the code adopted by the Australasian Institute of Mining and Metallurgy (“AusIMM”), The Australian Institute of Geoscientists (“AIG”) and other relevant stakeholders. This standard is binding upon all AusIMM and AIG members. The VALMIN Code incorporates the Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (“JORC Code”) for the reporting of Mineral Resources and Ore Reserves.
This Report is not a Valuation Report and does not express an opinion as to the value of mineral assets or make any comment on the fairness and reasonableness of any transactions related to the proposed IPO. Aspects reviewed in this Report may include geological prospectivity, current and planned exploration activities, socio-political issues and environmental considerations; however, Cube does not express an opinion regarding the specific value of the assets and tenements involved.
Based on Cube’s assessment of the NSW tenements, it is of our opinion that they are considered to be sufficiently prospective, subject to varying degrees of exploration risk, to warrant further exploration and assessment of their economic potential, consistent with the proposed programmes.
Proposed exploration expenditure for the current reporting period being two years following admission to the ASX (broadly FY2020 and FY2021) is expected to be A$2.7M to $5.5M (depending upon the total amount raised and progressive results), which Cube believes is sufficient to evaluate the properties to a level that Godolphin has stated in the IPO prospectus.
Neither Cube, nor the authors of this report, have or have previously had, any material interest in Godolphin or the mineral properties in which Godolphin has an interest. Our relationship with Godolphin is solely one of professional association between client and independent consultant. Cube has also not conducted any work for Ardea in the last two years. This report is prepared in return for professional fees based upon agreed commercial rates and the payment of these fees is in no way contingent on the results of this report. Preparation of this report cost approximately A$47,000 and is in line with the number of tenements, the areas covered and the volume of data and complexity.
Cube has based its report of the NSW tenements on information provided by Godolphin up to and including 26[th] October 2019. Additional information has included technical reports prepared by consultants, Government agencies, previous tenement holders project and annual technical reports, and other relevant published and unpublished data. Site visits to key prospects was also undertaken.
Where appropriate, and in accordance with ASIC Regulatory Guide 55, consent has been obtained to quote data and opinions expressed in unpublished reports prepared by other professionals on the properties concerned.

The legal status of the tenements, including Native Title considerations and other socio-political items, has not been independently verified by Cube. The current status of tenements listed in this report is based on information provided by Godolphin, and the report has been prepared on the assumption that the tenements will prove lawfully accessible for evaluation as has been the case to date.
Cube is an independent Australian owned company of consultants which has been providing a comprehensive range of specialist technical services to the mining industry in Australia and overseas since 2000.
This report has been compiled by Mr Andrew Grieve (BAppSc.), who is a professional geologist with over 25 years’ experience in mine production, exploration and evaluation of mineral properties within Australia and overseas. Mr Grieve is a Member of the Australian Institute of Geoscientists and has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the JORC code.
Mr Brian Fitzpatrick assisted in compiling the Yeoval section of the report and a technical review was completed by Mr Terje Hansen.
Cube has provided consent for the inclusion, in full or abridged by Cube, of the Independent Technical Assessment Report in the Prospectus, and to the inclusion of statements made by Cube, in the form and context in which the report and those statements appear, and has not withdrawn that consent before lodgement of the Prospectus with the ASX.
1.1. Tenements
Godolphin holds interests in 10 Exploration Licences and one Mining Lease (Table 1-1). All tenements are located in Southern and Central NSW (Figure 1-1) and are held by Ardea Exploration Pty Ltd and its associated subsidiaries. A further five tenements are under application.
Cube has reviewed the list of tenements provided by Ardea using the NSW Government Department of Planning and Environment MinView database. As Cube is not qualified to provide a legal opinion of their status, potential caveats, agreements and obligations, potential investors are guided to read the accompanying Solicitors report in the Godolphin prospectus.

1.2. Resources
Ardea has completed and released new and updated Mineral Resource Estimates (JORC (2012)) in August 2019 for Mt Aubrey and Yeoval and for Lewis Ponds in September 2019. A summary of these Mineral Resource estimates is tabulated in Table 1-2. More detailed explanation of these Mineral Resource estimates can be found in the respective sections of this report.

*Some rounding may occur
1.3. Regulatory Regime
All tenements fall under the NSW regulatory regime, which has a robust and workable system in place. There is considerable current mining activity and development within the area of the Godolphin tenure, including; Northparkes (China Molybdenum Co Ltd), Cadia (Newcrest Mining Ltd), McPhillamys (Regis Resources Ltd), Lake Cowal (Evolution Mining Ltd) and Tomingley (Alkane Resources Ltd).
1.4. Royalties and Taxes
The NSW Government can levy one of two types of royalties on non-coal minerals; Quantum and Ad Valorem. The minerals of interest to Godolphin are levied at 4% of the minerals recovered or ex-mine value, with some deductions allowed. For a more detailed explanation, readers are directed to read information on the NSW Government Department of Planning and Environment website.
1.5. Other Royalties
Mr David Timms owns a production royalty capped at A$2 million in relation to Lewis Ponds Main Zone.
Production royalties maybe attached to mining tenements upon sale as part of the sale consideration by previous tenement holders. Godolphin and its subsidiaries acquired the majority of project tenements by application and therefore no royalties exist.
1 Gold equivalents (AuEq) were defined using the following values (21 June 2019 US$ price, recovery): Zn ($2585/t, 80%), Au ($1393/oz, 100%), Ag ($15.50, 80%), Pb ($1915/t, 80%), Cu ($5960/t, 80%). Au equiv. = Au(g/t) + 0.011Ag(g/t) + 0.577Zn(%) + 0.428Pb(%) + 1.331Cu(%). Gold equivalence is subjective thus indicative only and is used to allow comparisons between major deposits of the region.

1.6. Social Considerations, Environmental, Native Title and Land Access Issues
Most of the tenements are on freehold title held by external parties. The only exception is a portion of land within the Lewis Ponds Project that is owned by TriAusMin Pty Ltd (currently a subsidiary of Ardea Resources Ltd).
Portions of the tenements of Ophir and Wisemans Creek require Native Title agreements before access can occur. Negotiations are currently underway with the relevant parties to gain access to them.
Cube has reviewed supplied land access agreements, however, cannot form a legal opinion on these, therefore potential investors are directed to the Solicitors report accompanying the prospectus. Cube has not reviewed any Native Title agreements.
Due to the proximity to population centres and freehold land, exploration activities can be restricted. There are numerous small landholdings within some of the areas which can make negotiating access protracted. One of the highest priority exploration/development projects (Lewis Ponds) has numerous dwellings within visual contact of the potential mine workings and therefore mining activities such as blasting and placement of waste dumps will need to be carefully considered.
A review of historical exploration reports did note in some areas that there were difficulties in gaining access to freehold land to carry out exploration activities. First pass exploration carried out recently by Ardea indicates there is a good working relationship between the company and some landholders. This relationship needs to continue and build with other landowners to ensure Godolphin has access to carry out its planned activities.
1.7. Mt Aubrey
Mt Aubrey is located approximately 40 km northeast of Parkes and 30 km southeast of Yeoval and consists of one tenement (EL8543) of around 194 km[2] .
At the southern edge of the tenement there are three backfilled open pits that were mined by BHP in the early 1990s. It is reported that around 100,000 tonnes at 3.0 g/t Au were mined (Ostrowski M. , 2019b) from an epithermal vein system. The tenement is also prospective for other deposit types, including porphyry copper-molybdenum, but only a few other minor historical workings are recorded.
The dominant rock types in the area are felsic intrusives, silicic to intermediate volcanics and minor sediments. There is an extensive sheeting of Tertiary and Quaternary alluvials over the tenement, especially over the southern and central portions.
Comprehensive stream sediment sampling has been carried out over the whole tenement. Other exploration activities include; surface mapping, geophysics and drilling, with the drilling mainly centred around the backfilled BHP pits.
A Mineral Resource Estimate was completed in August 2019 (Ardea Resources Ltd, 2019a), which is tabulated in Table 1-3. More details on the Mt Aubrey Resource can be found in Section 4.5.

1.8. Yeoval
The Yeoval tenement (EL8538) is located approximately 70 km north-west of Orange, centred around the town of Yeoval and covers an area of approximately 290 km[2] . This tenement is held by Ardea Exploration Pty Ltd. The area is underlain by granites, granodiorites and volcanics.
Two other adjoining tenements, ELA5780 and ELA5806 are currently under application.
There are numerous historical workings within the tenement, mainly for copper. Other later activities by various parties include; stream sediment, soil and rock chip sampling and limited drilling.
Ardea has carried out limited soil auger and rock chip sampling and the tenement is considered prospective for a porphyry copper-gold-molybdenum mineral systems.
A Mineral Resource Estimate was completed by Auger Resources in March 2009, and this has now been updated by Ardea in August 2019 (Ardea Resources Ltd, 2019b). This Mineral Resource Estimate is tabulated in Table 1-4. More details on this Mineral Resource Estimate can be found in Section 5.5.

There are numerous historical copper and gold workings mainly concentrated in the southeast portion of the tenement. Between the tenement and the township of Molong, the Copper Hill deposit (which is located outside the current Godolphin tenement), is estimated to contain an Indicated and Inferred Resource (at 0.4% Cu cut-off) of 28 Mt @ 0.56% Cu and 0.53 g/t Au (Golden Cross Resources, 2019). The recent Boda discovery by Alkane Resources Ltd (Alkane Resources Ltd, 2019), located approximately 70 km to the north (Figure 1-1) highlights the potential of this area due to the similar geological setting.
Modern exploration activities commenced around 1975 and consisted of various greenfield exploration methodologies through to minor drilling. Ardea has carried out soil auger sampling over approximately 7 km strike length in the northwest portion of the tenement.
This area is prospective for porphyry hosted copper-gold, VHMS and epithermal/mesothermal gold deposits.
1.10. Ophir
The Ophir Project consists of one tenement (EL8323) of around 174 km[2] . It is located around 15 km northeast of Orange. Ophir is famous for being the location of Australia’s first recorded gold rush. There are also several other workings in addition to the Ophir gold workings within the tenement.
The geology consists of Ordovician mafic volcanics, volcaniclastics and intrusions, Silurian-Early Devonian intermediate to felsic volcanics and volcaniclastics and Carboniferous felsic intrusions. The area appears to have a complex structural history with folding and thrust faulting present.
Only minor modern exploration activities have been carried out on the tenement, with stream sediment sampling being the most comprehensive.
This project is prospective for a variety of deposit styles including; porphyry hosted copper-gold, VHMS, orogenic gold and base metals.
1.11. Lewis Ponds
Lewis Ponds consists of one tenement (EL5583) which covers approximately 148 km[2] located around 15 km east of Orange. This project is one of the highest priority targets for Godolphin due to the extensive historical workings and infrastructure (including the presence of historic on-site smelting), outcropping mineralisation, a current Mineral Resource Estimate and free-hold title held by TriAusMin (a subsidiary of Ardea). Another tenement (ELA5794) centred around historic workings at Mt Bulga is currently under application.
The project area contains sediments and volcanoclastic sediments, which have been structurally deformed.
The project hosts massive sulphide and shear hosted copper mineralisation with a potential later stage gold overprint.
An updated Mineral Resource was completed in July 2019 (Ardea Resources Ltd, 2019c), which is tabulated in Table 1-5. This table is the combined open pit and underground Resource. More details on the Lewis Ponds Resource can be found in Section 8.5.

1.12. Wisemans Creek
The Wisemans Creek Project is centred around the town of Oberon, consists of one tenement (EL8445) and covers an area of approximately 229 km[2] .
Historically this area has been an active mining area with commodities such as; gold, copper, tungsten, molybdenum, lead, zinc and silver being exploited.
Exploration in the area has been recorded from the late 1960s through to the present day. The project area is mainly prospective for epithermal gold-silver and skarn and mesothermal type mineralisation.
1.13. Calarie
There are three tenements (EL8555, EL8580 and ML739) within the Calarie Project, covering an approximate area of 137 km[2] . The tenements are located directly to the north of the township of Forbes.
The tenements are located within the Forbes-Parkes Belt, which hosts numerous medium to large scale Mineral Resources and more recent historical and active gold mines including; London Victoria (BHP), Peak Hill (Alkane) and current Tomingley gold mine (Alkane). There are also numerous historical workings throughout the tenement, especially around the historic mining centre of Calarie.
The area is prospective for gold, which are usually structurally hosted within sediments and on favourable lithological contacts.
Systematic recent exploration has occurred over the area by various parties since the late 1980s, ranging from geochemical methods, geophysics, through to drilling.
Prior mineral estimation work has been undertaken at Calarie by various companies, however, these estimations are not compliant with JORC (2012) and cannot be disclosed by Godolphin.
1.14. Gundagai
There are two tenements within the Gundagai Project; EL8061 (Gundagai South) and EL8586 (Gundagai North) totalling around 278 km[2] , located south and north respectively from the town of Gundagai. Another tenement (ELA58090) which joins together the already existing granted tenements is under application.

This area has a long history of mining and hosts abundant historical workings, mainly for gold, but also minor copper. There are no current mining activities or reportable Mineral Resources located within these tenements or adjacent areas.
Due to the past mining activities, exploration within the area commenced in the mid-1960s and has essentially continued at a low level since.
The area is prospective mainly for orogenic gold and Intrusive Related Gold Systems (IRGS), but also has the potential for VHMS and porphyry hosted copper-gold deposits.

2. Introduction
2.1. Scope and Terms of Reference
Cube has prepared this ITAR on behalf of Godolphin for use in a prospectus to support an IPO of their NSW tenements.
Godolphin’s assets consist of 11 tenements (ten exploration licences and one mining lease) within the prospective Lachlan Fold Belt (LFB), covering approximately 1511 km[2] located in Central and Southern NSW. A further five exploration licence applications have been submitted. The current granted tenements have been divided into eight different Projects (Figure 1-1). These Projects include:
-
Aubrey
-
Yeoval
-
Copper Hill East
-
Ophir
-
Lewis Ponds
-
Wisemans Creek
-
Calarie
-
Gundagai
The Projects are mainly prospective for gold and base metals and the majority of these Projects have undergone historical mining activity. More recent exploration activities over these Projects have ranged from greenfield activities such as mapping and auger sampling, through to more advanced activities such as drilling and estimation of Mineral Resources.
A tenement schedule was supplied to Cube by Godolphin to define the project areas for the ITAR. The agreed scope with Godolphin included the following:
-
Tenure, permitting and royalties (a high-level review as a detailed review will be undertaken separately by suitably qualified legal personnel).
-
Environmental status, liabilities and land access (high-level).
-
Data – origin/source, validity, QAQC and management/storage.
-
Planned exploration activities.
-
Geology – local and regional.
-
Prospectivity.
-
Resources (Lewis Ponds, Yeoval and Mt Aubrey).
-
Future activities – development plans and budgets.
-
A site visit to selected Projects was required to review:
-
access and infrastructure
-
on-ground geology
-
historical workings
-
historical and current exploration activities and data.
This Report does not provide a valuation of the mineral assets and has been prepared to the standard of, and is considered by Cube to be, an Independent Technical Assessment Report in accordance with the Code and Guidelines for Assessment and Valuation of Mineral Assets and Mineral Securities for Independent Expert Reports (VALMIN Code). The VALMIN Code is the code adopted by the Australasian Institute of Mining and Metallurgy (AusIMM) and the standard is binding upon all AusIMM members. The VALMIN Code incorporates the Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code) for the reporting of Mineral Resources and Ore Reserves.

2.2. Background
Ardea has an extensive tenement portfolio throughout NSW and WA, which are at various stages of exploration and development (Figure 2-1). These projects include:
-
the advanced Goongarrie Nickel-Cobalt Project in WA
-
gold and nickel sulphide projects in WA
-
gold and base metal projects in NSW.
==> picture [452 x 296] intentionally omitted <==
Figure 2-1 Location of Ardea Projects
The Goongarrie Nickel-Cobalt Project (“GNCP”), within the Kalgoorlie Nickel Project (“KNP”), is the most advanced, with a Mineral Resource of 773 Mt at 0.7% Ni and 0.05% Co. Pre-feasibility studies for 1.0 Mtpa and 1.5 Mtpa throughput options have been completed, as well as a Scoping Study for a 2.25 Mtpa option. Definitive Feasibility Study (“DFS”) programs are currently in progress (Ardea Resources Ltd, 2019).
The WA gold and nickel sulphide assets are at various stages of exploration and development, with first pass drilling already completed at Mt Zephyr and the Bardoc Tectonic Zone.
The Ardea NSW tenements consist of eight Projects, which are prospective for gold and base metals. Most have a long history of mining activities, have various levels of modern exploration activities already carried out, and three have current Mineral Resource Estimates.
Ardea intends to spin out the NSW gold and base metal Projects into the separate listed entity of Godolphin to enable Ardea to concentrate on its WA projects. It is proposed that the IPO consist of the

issue of least 22.5M shares to a maximum of 40M shares, to raise from a minimum of A$4.5M to a maximum of A$8M.
2.3. Reporting Standards
This Technical Assessment Report is prepared in accordance with the following codes:
-
The 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves of the Joint Ore Reserve Committee (JORC Code)
-
The 2015 edition of the Australasian Code for Public Reporting of Technical Assessments and Valuation of Mineral Assets “VALMIN Code” mandatory from 1 July 2016
2.4. Data Sources
Cube has relied on several sources of information, including relevant published and unpublished thirdparty information, and public domain data. This included copies of reports supplied by Ardea associated with the tenements, both historic and current open file company reports. Cube has reviewed these reports and cross-checked a selection with the open file report databases of the NSW Government Department of Planning and Environment Geoscience database (“MinView”). Cube has accepted the data provided by Godolphin subject to these checks at face value. Cube has sought written confirmation from the directors of Godolphin and Ardea that all the information available in their possession or knowledge relating to the tenements has been made available to Cube.
Cube has validated the tenement information provided by Godolphin via the NSW Government Department of Planning and Environment MinView database, however potential investors are recommended to review the accompanying Solicitor’s Report on Tenements that is contained within the Prospectus, as Cube is not qualified to express legal opinion and has not sought any independent legal advice on the ownership rights and obligations relating to the respective mineral assets under licence, or any other fiscal or legal agreements that may exist with any third parties.
Cube has sought and received written confirmation from the Directors of Godolphin and Ardea that a full, accurate and true disclosure of all material information has been supplied.
Mr Andrew Grieve has visited the Mt Aubrey, Yeoval, Copper Hill East, Ophir and Lewis Ponds Projects to conduct on-site reviews. The site visit confirmed the existence of historical mining activities, recent exploration activities, both mineralised and non-mineralised outcrop, access, infrastructure and potential socio-political issues. Site visits were not made to Wiseman’s Creek and Gundagai as these Projects were considered as earlier stage exploration Projects.
2.5. Reliance On Other Experts
Cube has relied on other experts with respect to:
-
Lewis Ponds, Yeoval and Mt Aubrey Mineral Resources: JORC (2012) Mineral Resource estimates have been completed by Mr Johan Lambrechts. Mr Lambrechts has consented on his report as part of this ITAR as noted in Table 1-3, Table 1-4 and Table 1-5.

3. Regional Information
3.1. Geology
The tenements lie within the Lachlan Fold Belt (LFB), also known as the Lachlan Orogen, which was part of a convergent plate margin that formed part of Gondwana. The LFB is dominated by Lower Palaeozoic sediments, calc-alkaline volcanics and granitic intrusions. Accretion started during the late Ordovician (~450 Ma) resulted in various stages of deformation and metamorphism (Foster & Gray, 2000).
On a more local scale, the Ardea tenements are located within or adjacent to the Lachlan Transverse Zone (LTZ). This is a west-northwest trending zone that extends from the western part of the LFB and into the Sydney Basin. The western part is defined by west-northwest trending faults with the eastern section having similar trending faults and folds, both of which are later than the main structures contained within the LFB. The LTZ is thought to be a reactivation of a deep crustal weakness (Glen & Walshe, 2010). Many of the significant mineral deposits in the area lie within or adjacent to this zone e.g. Cadia, McPhillamys and Northparkes (Figure 1-1).
Of particular interest, the Lewis Ponds, Ophir and Copper Hill East tenements, lie on or in close proximity to the Godolphin Fault. This is a shallow east-dipping structure, which forms part of an east dipping thrust zone. The Godolphin Fault and its northern correlative, the Narragul Fault, demarcates through a series of sidesteps and splays the domains of the Ordovician Macquarie Arc in the west from the Silurian Hill End Trough in the east. This structure hosts copper and gold mining centres and targets such as McPhillamys, Springfield, Mt Shorter, Calula and Copper Hill.
3.2. Climate, Vegetation and Topography
The Orange region has a temperate climate with mean maximum temperature of around 10°C and 25°C in winter and summer respectively. Snow falls are not uncommon. The average annual rainfall is 916 mm. Climate conditions have little or no impact on exploration or mining activity.
Topography varies from flat to low undulating around drainage areas to steeply undulating ranges and hills to the south-west and north-east of Orange at elevations up 922 m.
In the majority, the lower lying and undulating areas have only remnant vegetation and is mainly used for sheep and cattle grazing, while the steeper areas are forested with primary eucalypt or lumber (commonly pine) plantations. Elevated timbered areas are often characterised by historic mining activities.
3.3. Infrastructure
Orange is a major regional centre, with a population of approximately 40,000 located about 200 km west-northwest of Sydney. The area is well serviced by major roads and has daily air and road services to Sydney. An extensive rail network already services the mining sector.
3.4. Current Mining Activity
There are several major open pit and underground mining operations in the vicinity of the Godolphin tenements including:
Page | 15
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
-
Cadia Valley Operations (Newcrest Mining Ltd) – Large tonnage underground block cave copper-gold mine, located 25 km southwest of Orange. In FY2017-18 it produced 600 Koz of gold and 62 Kt of copper. Cadia has a Mineral Resource of 38 Moz of gold and 8.3 Mt of copper.
-
• McPhillamys (Regis Resources Ltd) – Located 8 km from Blayney and 20 km southeast along the Godolphin Fault structure from Lewis Ponds. McPhillamys has a Reserve of 60.1 Mt at 1.05 g/t Au and currently has development applications in progress.
-
Northparkes (CMOC) – Underground copper-gold mine. Processed 6.5 Mt in 2017. No public reportable Mineral Resources or Reserves are available.
-
Tomingley (Alkane Resources Ltd) – Current open pit gold with underground development in progress. Located approximately 50 km to the southwest of Dubbo and 50 km northwest of the Mt Aubrey Project. In FY 2017-18 produced 79 Koz of gold and has an Indicated and Inferred Mineral Resource of 6.8 Mt at 2.0 g/t Au.

4. Mt Aubrey
4.1. Location and Access
EL8532 is located approximately 70 km northwest of Orange, centred on the locality of Baldry (Figure 4-1). Renshaw McGirr Way, which is a sealed road running from Yeoval to Parkes, runs through the centre of the tenement. The tenement covers an area of approximatley 194 km[2] .

Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
4.2. History
This project has only minor historical workings (there are gold workings at Blue Hills (Figure 4-4) and there are references to other workings from the 1880s around Mt Aubrey). Recent activity did include BHP in 1990 mining three shallow oxide pits at Mt Aubrey, producing around 100,000 tonnes of ore at around 3.0 g/t Au. The deposit was based on an epithermal vein system.
4.3. Geology
4.3.1. Setting
The north to north-eastern part of the project area is dominated by the Yennora and Kynura granites. There are also small outcrops of the Cuga Burga mafic volcanics throughout and in the southern area the Dulladerry Volcanics. An amygdaloidal basalt within the Dulladerry Volcanics hosts the Mt Aubrey gold deposit mined by BHP.
There is an extensive sheeting of Quaternary gravels, particularly in the southern portions of the tenement, which has made the collection of relevant soil geochemistry difficult (requiring a vehiclemounted auger typically drilling to 2 m to take a representative sample).
4.3.2. Alteration and Structure
The north-eastern corner of the tenement is crossed by a series of northwest trending faults, which appear to slightly offset the stratigraphy.
A west-northwest orientation of the Mt Aubrey deposit is thought to be an en-echelon array partly controlled by the location of major north trending regional structures to the west and east of EL8532 (Ostrowski M. , 2019a).
4.3.3. Deposit Type and Mineralisation
The Mt Aubrey deposit, mined by BHP, is within an approximately 6 km long east-west trending vein system (Figure 4-2). Quartz vein textures and fluid inclusion studies indicate an epithermal type deposit (Ostrowski M. , 2019a). The Cube site visit also noted similar style mineralisation and associated rock types including; bladed textures and siliceous cap material (Figure 4-3).

Figure 4-3: Bladed textures and siliceous cap material
Surface mapping and drilling indicates that the Mt Aubrey vein system pinches, swells and bifurcates along strike and it is postulated that the vein system has preferentially developed within the more brittle and chemically favourable amygdaloidal basalts rather than the other surrounding felsic rocks.
Information pertaining to the Blue Hills workings (Figure 4-4) is scarce, with MinView database only noting epithermal veining, however mapping indicates this is a strike extension to the main Mt Aubrey vein set (Figure 4-2).
Further north, the Moly Veins (Figure 4-4) are noted to have molybdenite within veining hosted in the Kynuna Granite.
4.4. Previous Work
Records indicate that modern exploration commenced in the area by Anaconda in the 1960s. Numerous companies have been active in the area including; Samedan, Geopeko, BHP, Newcrest and Alkane. A brief summary of their activities is tabulated in Table 4-1. A tenement review by Ostrowski (2019a) has determined a series of prospect areas (Figure 4-4) and these are used to tabulate a summary of exploration activities and the results (Table 4-2).

4.5. Resources
A Mineral Resource Estimate was completed in August 2019 (Ardea Resources Ltd, 2019a). The Mineral Resource Estimate was reported using a number of gold cut-off grades as tabulated in Table 4-3 and all Resources were classified as Inferred. A ≥0.5 g/t Au cu-off was used as a base case.

The following is a summary of the data, parameters and methodology used in the 2019 Mineral Resource Estimate:
-
The deposit is hosted in a 130 m thick pillow-textured, subaqueous amygdaloidal basalt and the mineralisation consists of low-sulphidation epithermal-style quartz veining that pinches, swells and bifurcates along an approximate 7 km strike length that trends in a west north-west direction.
-
The percussion drilling (RC, RAB and AC) was sampled on 1 m intervals. The majority of the DD was sampled on 1 m, with some sampled on other interval lengths to take into account changes in geology and mineralisation. DD drilling samples were collected on half core.
-
The Mineral Resource Estimate was calculated from 219 drillholes (157 RC, 3 DD, 28 AC and 31 RAB) consisting of 9,382 m of drilling. There were two major periods of drilling. These included:
-
BHP Gold (1987 – 1990)
-
YTC Resources (2007 – 2011)
-
The whole Resource was classified as Inferred. In some areas the drill spacing of 20 m × 20 m would be sufficient to classify as Indicated or Measured, but the Inferred category was assigned due to concerns about historic data integrity and assignment of void pit shapes using ground penetrating radar (GPR) rather than survey data.
-
Analysis for gold was undertaken by fire assay.
-
Four separate mineralisation domains were created using implicit modelling in Leapfrog software and these domains were estimated by ID[2] using Leapfrog Edge. Search parameters were based on the variogram models with ellipsoid searches being used to set a maximum of 20 and minimum of 10 samples for each interpolation. Parent cells of 5m (X), 10 m (Y) and 10 m (Z) and subcells of 1 m (X), 1m (Y) and 1 m (Z) were used. Validation of the estimation was carried out using historic production reports.
-
No top-cuts were applied as it was considered that there were no extreme outliers. The Mineral Resource Estimate was reported on a ≥ 0.50 g/t cut-off, but also reported in ≥0.25 g/t, ≥0.75 g/t and ≥1.00 g/t (Table 4-3).
-
No geotechnical or metallurgical testwork has been completed on Mt Aubrey drill samples. Due to the historic production from Mt Aubrey and similar low-sulphidation epithermal gold deposits within the LFB, it was assumed that it would be amenable to conventional open pit mining and processing.

4.6. Exploration Potential
There is a high potential to increase the current Mineral Resource for Mt Aubrey as most of the current drilling is restricted to around 50 m below surface and also restricted along strike (Figure 4-7), hence leaving large sections poorly or not tested at all. In 2007, YTC Resources drilled three diamond holes beneath the existing drilling in which all holes intersected anomalous values, but due to their wide spacing (250-350 m) higher grade shoots could have been missed. There is also some uncertainty on drill collar locations, in which Ardea where unable to confirm. It is recommended that drilling initially be targeted at down plunge areas of shoots that have already been identified.

Modelled images from GPR that was commissioned by Ardea to determine the location and depth of the backfilled BHP pits, has highlighted potential veining below the existing pits that align with mapped surface veining (Figure 4-8). These require confirmation drill testing to determine their nature. Recent soil geochemistry by Ardea along strike to the east and west of the historic pits has also highlighted gold anomalies (Figure 4-5) again highlighting potential untested mineralised strike extensions.

There are several other locations adjacent to main Mt Aubrey area that show interesting potential that warrant follow-up. These include (in no particular order):
- An area approximately 1 km north of Mt Aubrey (Mt Aubrey North) that has mapped east-west trending veins, significant areas of epithermal textured quartz float with anomalous gold values. This area also has co-incident induced polarisation (IP) anomalies similar to Mt Aubrey.

-
The Emu Swamp area has returned molybdenum anomalies from recent soil auger testing, has mapped veins that have significant rock chips values, noted strong sericite alteration and is along strike from the known Mt Aubrey deposit.
-
The area around the historic Blue Hills workings along strike from Mt Aubrey where there is mapped veining, significant rock chips and noted strong alteration.
4.7. Proposed Exploration
Godolphin is planning to undertake an RC drilling program in and around the Mt Aubrey deposit and use this to update the geological model and the current Mineral Resource Estimate. This may also lead to defining further drilling activities. Oriented core from diamond drilling is planned to define vein orientations and to obtain unbroken material for bench-scale metallurgical test work.
Portions of the tenement will also be soil sampled – mainly concentrating in the areas of Blue Hill, Mt Aubrey South, Far North and East, as well as Emu Swamp.
For the FY2020-21, expenditure is expected to be approximately A$0.86M to A$1.94M (depending upon the total amount raised and progressive results).

5. Yeoval
5.1. Location and Access
The Yeoval Project is located approximately 70 km northwest of Orange in central New South Wales. The tenement EL8538 covers an area of approximately 290 km² (Figure 5-1). More than 60 historic mine workings occur within EL 8538 and these trend in a north-easterly direction along a 20 km strike length.
Two other tenements, ELA5780 and ELA5806 that abut the southern and northern boundary of EL8538, are currently under application.
The Yeoval Project area is readily accessible via sealed and unsealed roads and is adjacent to the Molong – Dubbo railway infrastructure. The Project area is within easy reach of the Mitchell Highway to the east.

Figure 5-2 Location of Historical Workings within Yeoval Tenement (Arundell 2019)
The tenement (EL 8538) covers an area of ~290 km², was granted on 19 March 2017 to Ardea Exploration Pty Ltd. Ardea is exploring for a large tonnage porphyry copper-gold-molybdenum-rhenium system in the Yeoval area.
Previously the area included a number of smaller EL tenements. A summary of the history of the most significant of these tenements, identified by the prospect names where known, is summarised as follows.
The Yeoval prospect is a typical porphyry copper system. The many copper\gold showings in the Yeoval district have been explored almost continuously since the 1960s, though mostly at shallow levels only. The major explorers have been Noranda, Hastings\Geopeko, Glendale, Lynch Mining, BHP\Newcrest and CRAE.

Previous companies have explored a total of 38 prospects to varying degrees, with much of the work centred on the Yeoval and Goodrich prospects. Of these 38 prospects, 14 have been drilled, including 12 with RC drilling and 7 with diamond drilling. A total of 86 RC holes and 35 diamond drill holes have been completed in the Yeoval district by previous explorers (Meares, 1998).
Most of this exploration was carried out prior to the Discovery 2000 airborne magnetics and radiometrics becoming available for parts of the Lachlan Fold Belt including the Yeoval district.
Malachite Resources was the only explorer in recent years to hold all tenure over the Yeoval district, and thus the only explorer to systematically explore the district as a single mining camp.
During the past five years, Malachite conducted a comprehensive exploration program at Yeoval, mainly searching for porphyry style copper-gold deposits (e.g. Goodrich) but also high-grade gold vein systems (e.g. Thunderbolt). Work conducted has included compilation of previous exploration and mining records, gridding, geological mapping, soil and rock geochemistry, ground magnetics, induced polarisation (IP) surveying, trenching, and both reverse circulation drilling and diamond drilling programs.
Prospects tested by drilling include Goodrich (16 holes including three holes drilled in 2002), Thunderbolt (5 holes, including 2 holes drilled in 2002), Ironbark Hill (1), Bellmain (2), West Timbie (1) and Dilga Creek (2 holes). The only potentially economic mineralisation discovered in these programs was the disseminated chalcopyrite mineralised zone at Goodrich.
At Goodrich, a ring structure composed of vein-style quartz-magnetite-chalcopyrite (“QMC”) mineralisation, with significant gold credits, has been mined to at least 54 m depth. It is the largest recorded copper\gold producing mine in the district. The Goodrich deposit (located on an excised mining lease which is surrounded by Godolphin tenure) was discovered around 1868 and worked intermittently to 1912. Initially it was worked from an open pit to ~46 m depth. A shaft on the north side of the open pit extends to approximately 90 m depth (300 feet) with working levels at 20 m, 36 m and 54 m below the surface. In addition, the first drill hole in Malachite’s 1998 drilling program (GRDD 01) intersected the old workings at a depth of 85 m below surface. The mining exploited a cone-shaped structure comprising quartz-magnetite-chalcopyrite lodes up to 4 m wide, with strong similarities to the veining at Ridgeway. The production from the mine is uncertain but is estimated at about 299 t copper, 159 kg gold, 62 kg silver. The Goodrich ore consisted of disseminated chalcopyrite, with minor molybdenite, bornite and pyrite.
5.3. Geology
5.3.1. Setting
Ardea’s Yeoval Project is located in the Cowra Zone of the Lachlan Orogen and contains Devonian granite and granodiorites of the Yeoval Batholith (Figure 5-3). East and north of the intrusive complex are Silurian and Devonian aged sedimentary and volcanic rocks.
A number of strike-extensive north-south trending fault structures have been mapped in the region, primarily in the Ordovician and Silurian lithologies lying to the east of the Yeoval Batholith. The Batholith itself trends northerly, in a general sense controlled by the north-south faulting. Internally, granodiorite, which forms the eastern third of the Batholith, trends north-north-easterly. Numerous north-westerly trending faults transect the Batholith. These structures also occur in the older lithologies in the south of the licence area. Some explorers have suggested that these north-westerly trending structures may have played some role in the location of mineralisation. However, mineralisation appears to be localised within the Yeoval Granodiorite, rather than along the length of faulting.

Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
The Yeoval Project covers a broad area of the Devonian Yeoval Batholith which includes felsic to mafic intrusions of the Yeoval Complex – granite (Kynuna & Glenrowe), quartz monzodiorite, quartz diorite, granodiorite (Naringla), diorite and gabbro (Figure 5-1).
The Silurian Canowindra Volcanics (garnetiferous quartz-feldspar-cordierite tuffs, volcanics and breccias) and Hanover Formation (siltstone, shale and minor chert) lie to the east of the Batholith. A core of Ordovician sandstone, siltstone and minor limestone of the Kabadah Formation lies within the Silurian sediments and volcanics and is predominant in the central part of the licence area. Devonian volcanic and volcaniclastic rocks in the area comprise the Cuga Burga Volcanics (latitic, crystal-lithic sandstone, breccia, siltstone, tuff, latite) of the Gregra Group.
The interpretation of the local geology and the effects of faulting, has been aided by the regional airborne geophysical data, which was commissioned by the NSW Geoscience Mapping Accord and flown in 1991. Numerous northwest fault sets have been defined from mapping and aeromagnetic interpretation. Detailed magnetics flown by a number of companies – in particular Altius Mining (EL7036) - have enabled enhancement of the geological and structural interpretation of the Yeoval area.

5.3.2. Deposit Type and Mineralisation
Copper, gold and other base metal mineralisation is widespread in the region and the main mineralisation styles include:
-
Porphyry style copper-gold mineralisation associated with Devonian calc-alkaline intrusions e.g. Yeoval, Cyclops, Goodrich prospects.
-
Skarn mineralisation hosted by mafic units in the Cuga Burga Volcanics.
-
Low sulphidation epithermal gold mineralisation in Middle Devonian volcanics e.g. Mt. Aubrey gold deposit.
-
Structurally controlled quartz-copper ± gold vein mineralisation in Ordovician to Devonian sedimentary rocks and volcanics.
Numerous copper-gold occurrences are known in the Yeoval Complex. Mineralisation ranges from disseminated chalcopyrite-gold within altered granodiorite (Yeoval, Yeoval South) to quartz\magnetite\chalcopyrite veining within structures(?) within the granodiorite, at the Goodrich Mine. Minor molybdenum is reported at the Martins Reef Prospect in the south-west of the licence area. The style of the mineral occurrences is indicative of a porphyry copper-gold setting.
Minor occurrences of copper ± gold mineralisation are present within the microgranite and granite of the Yeoval Complex. Scattered copper-gold prospects also occur within the Silurian and Devonian sequences east of the Yeoval Batholith.
5.4. Previous Work
Over 70 copper and gold occurrences have been recorded within the Yeoval Complex, and a significant number of these are located on or close to the north-westerly trending structures. Most of these are of porphyry or vein style in intrusive-related settings, with the Goodrich (within excised area) and Yeoval (within Godolphin tenure) being the most significant deposits.
The many copper\gold showings in the Yeoval district have been explored at a low level almost continuously since the 1960s. The major explorers have been Noranda, Hastings\Geopeko, Glendale, Lynch Mining, BHP\Newcrest and CRAE. A brief summary of their activities is tabulated in Table 5-1. During the course of these activities and from historical naming, a series of prospect areas were named (Figure 5-2). Table 5-2 summarises the results of these exploration activities and the results.

The following is a summary of the data, parameters and methodology used in the 2019 Mineral Resource Estimate:
-
The mineralisation style is considered to be a porphyry copper-gold style and consists of chalcopyrite, bornite and molybdenite veins and stockwork within porphyritic granodiorite and monzonites. Three main mineralisation domains were created using copper values ≥ 0.1%.
-
RC drilling samples were collected by splitting 1 m intervals through a riffle splitter. DD drilling sample intervals varied depending upon mineralisation potential (0.5 m-1.0 m for identified mineralisation and 1.0 m-1.5 m intervals for non-mineralised material) and half core was submitted for assay. Some re-sampling by quarter core was carried out in 2009 on DD core obtained during the 1972-1974 drilling campaign.
-
The Mineral Resource Estimate was based on 45 drillholes for a total 7,319 m. This consisted of eight RC holes (793 m) and 37 diamond holes (7,319 m). Drilling was carried out in two stages. This included and was completed by:
-
Hastings in 1972
-
North Broken Hill in 1975.
-
The whole Mineral Resource Estimate is classified as Inferred as it is considered that:
-
Collar and downhole survey data is sufficient.
-
The continuity of copper mineralisation >0.1% is considered to be generally good.
-
The estimation of grades into the blocks is limited to blocks that have a first pass informing composite of <50 m.
-
The removal from the estimate of barren post-mineralisation dykes.
-
For the RC drilling programs, copper was analysed by Atomic Absorption Spectrometry (AAS), molybdenum by aqua regia digest and AAS analysis and gold\silver via acid digest and followed by AAS. For the DD drilling programs, copper was analysed using AAS, molybdenum via aqua regia and AAS and gold\silver by acid digest and AAS.
-
An Ordinary Kriging estimate was carried out on three separate domains that were based on a >0.1% copper threshold. No separate domains for the other elements were created. Two metre sample composites were used to populate blocks of 10 m (X), 20 m (Y) and 10 m (Z) in dimensions. Post-mineralisation dykes and material above the base of weathering were depleted from the Resource.

No top-cuts were applied as it was considered there were no outlier values. The Mineral Resource Estimate is reported on a 0.2% copper cut-off grade, but cut-off grades of 0.1%, 0.3%, 0.4% and 0.5% copper were also reported (Table 5-3).
-
No metallurgical or geotechnical studies have been completed on Yeoval drill samples, however as this deposit is considered to be similar other central NSW porphyry copper deposits, it has been assumed that it would be amendable to conventional open pit mining techniques and flotation-based processing.
For a more detailed explanation of the Yeoval 2019 Mineral Resource Estimate, readers are directed to read the Ardea ASX release dated 15[th] August 2019 (Ardea Resources Ltd, 2019b) or Appendix 2 in this report.
5.6. Exploration Potential
Due to the extensive mining history, encouraging drill results and current Resources, this Project is considered to have a good potential for further discoveries and\or extensions of known mineralisation.
To gain a better understanding of mineralisation of the area it is recommended that any historical core be reviewed\re-logged. This would include core from Yeoval and Cyclops. According to previous reports, a selection of this core is stored at the NSW Government Department of Planning and Environment Londonderry core library. It is also recommended that for Yeoval East, the CRAE drill database be evaluated to assist in drill targeting. Similarly, the Yeoval prospect drill database requires further validation and with the current Mineral Resource Estimate, this will then outline what further drilling is required.
The Vaughans Ridge\Ironbark Hill\Obley Gossan area is a high priority for a soil auger program and in conjunction of a full review of existing soil data e.g. CRAE and GSNSW 1977 program will further assist in prioritising areas for follow-up.
5.7. Proposed Exploration
The next stage of exploration is expected to consist of reviewing historic data to compile conceptual geological models, extend soil sampling to the south of existing Godolphin soil sampling in the Vaughan’s Ridge area and design a drill program around the current Yeoval Resource. The expenditure commitment is expected to be around A$0.18M to A$0.34M (depending upon the total amount raised and progressive results).

6.3. Geology
6.3.1. Setting
In general, the tenement contains the north trending Early Ordovician to Early Silurian Molong Volcanic Arc (MVA), in which the western portion within the tenement consists mainly of Ordovician mafic volcanics and volcaniclastics and the eastern portion consisting of Silurian felsic volcanics, sediments and limestones. The MVA hosts both porphyry hosted copper-gold mineralisation (Cadia-Ridgeway, Boda and Copper Hill) and skarn related deposits such as Browns Creek (Arundell, 2019).
6.3.2. Alteration and Structure
The MVA is dominated by major north-south trending strike slip fault arrays which generally mark the contact between Ordovician volcanic rocks in the west and younger geological units in the east. These are thought to be relevant to the gold and base metal mineralisation in the area.
It is thought that north-westerly trending structures have significant control on mineralised intrusive bodies (Copper Hill) and post-mineralisation deformation at the majority of known copper-gold deposits in the area.
Previous workers have noted a variety of alteration assemblages. The most notable are the sericite, hematite, epidote, quartz and carbonate within the Oakdale Formation (located in the western portion of the tenement within the Ordovician volcanics). Weak potassic and propylitic alteration has also been observed in a monzodiorite intrusion in the northern part of the tenement.
6.3.3. Deposit Type and Mineralisation
Work from previous exploration activities indicates that this project contains VHMS, skarn and mesothermal gold type occurrences. Lithologies within the tenement are conducive to these types of deposit styles. Most appear to be of limited extent and there appears to be a strong re-mobilisation component in the noted mineralisation.
Small scale epithermal\mesothermal deposits are characterised by small stockworks or brecciated and crustiform quartz, often associated with historical alluvial workings.
Lenses of massive sulphides/base metals have been noted e.g. Calula Pyrite Mine, but most other noted occurrences of base metals show strain, recrystallisation or other remobilised features.
6.4. Previous Work
As far as can be ascertained, modern exploration activities commenced in the area in the mid-1970s. Numerous companies have been active in the area including; Kamilaroi Oil, Samedan, Aquitaine, Amoco/Shell, Tri Origin/Delta Gold JV, Alkane, Comet and Newmont. A brief summary of their activities is tabulated in Table 6-1. During the course of these activities and from review work conducted by (Arundell, 2019), a series of prospect areas were assigned (Figure 6-2). Table 6-2 summarises these exploration activities and the results.

Current work by Ardea includes field observations and an approximate 7 km long soil auger sampling program carried out in the northwest corner of the tenement (Figure 6-3 and Figure 6-4). The program was spaced at 80 m × 80 m grid and results have outlined one 800 m × 800 m copper anomaly (150500 ppm Cu) and two small anomalies of lesser extent (Figure 6-3). There are also zinc anomalies but restricted to smaller areas (Figure 6-4). According to the NSW surface geology maps, the anomalous zone occurs between the Curra Creek and Neurea west dipping thrust faults and close to the contact between a conglomerate unit and an intermediate igneous rock. Cube field observations noted that the area is on, or close to a ridgeline and outcrop observed included conglomerates, carbonate veining, carbonate replacement textures and silica cap material (Figure 6-5).

6.5. Resources
There are no recorded Mineral Resources located within this tenement.
6.6. Exploration Potential
This Project has the potential to host VHMS and skarn style deposits and to a lesser extent mesothermal gold mineralisation. The site visit by Cube to the northern part of the tenement did note some carbonate replacement textures, which indicate a higher-level mineralisation style compared to the mesothermal style initially proposed.
The potential to host porphyry copper-gold type deposits would appear to be low due to the paucity – at least in outcrop – of intrusive host rocks. However, the potential presence of buried porphyry type mineralisation cannot be ruled out but would require a more concerted exploration strategy to identify distal propylitic and then phyllic alteration to confirm or deny the presence at depth of the prime potassic alteration style – similar to a Cadia-Ridgeway and Boda mineralisation models. The fact that traces of copper mineralisation, associated alteration and the tenements location within a similar geological
Page | 48
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
setting to known porphyry copper-gold occurrences (Cadia-Ridgeway and Boda) has already been noted in this tenement, does highlight the potential of this area.
Historical workings and data from exploration activities appears to indicate that VHMS (sulphide lenses) and mesothermal style mineralisation are present, however they appear of limited extent. Drilling that has been carried out has produced narrow significant intersections only. However, it is noted that drilling has been very restricted in extent.
With the identification of the McPhillamy’s orogenic gold deposit along a structure to the south and the historic Calula gold workings in particular require careful analysis for comparable mineralisation styles.
A more comprehensive data compilation and further soil geochemistry will allow Godolphin to vector into more prospective targets within this tenement. Historical soil chemistry has been carried out with some anomalies noted, however it is impossible to determine if the methodologies applied to these programs were appropriate and hence some caution should be applied to their results.
6.7. Proposed Exploration
The main proposed exploration activities will be based on gaining land access so the current soil sampling can be extended and areas that are considered prospective can be soil sampled and mapped. Expenditure is planned to be around A$0.39M to A$0.83M (depending upon the total amount raised and progressive results) for the coming reporting period

7. Ophir
7.1. Location and Access
The Ophir Project tenement (EL8323) runs from approximately 20 km north of Orange in a southeasterly direction to around 30 km southeast of Orange (Figure 7-1). The historic gold mining centre of Ophir is in the middle of the tenement. The tenement covers an area of approximatley 174 km[2] .

Page | 50
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
7.2. History
The Ophir Project has a rich history of gold mining, with the first payable gold workings commencing in 1851. These workings are considered to be the first payable goldfield in Australia. Mining included hard rock, alluvial and deep lead mining. It is reported that small scale deep lead mining is still occurring or has only recently ceased (Vassallo J. , 2019b). Historical location names for workings included; Ophir, Dead Horse Gully, Summerhill Creek and Pine Forest. These are all recorded as being gold occurrences. This is one noted occurrence of copper workings (MinView, 2019) within the tenement, located approximately 4.5 km east of the Lewis Ponds workings.
7.3. Geology
7.3.1. Setting
The area contains the Early Devonian deep marine and volcanic rocks of the Bay and Cunningham Formations, which are part of the Hill End Trough and rocks of the Early to Late Silurian Mumbil Shelf Group including the Mullions Range Volcanics, the Barnby Hill Shale and the Anson Formation. The far northern part of the tenement contains the Oakdale Formation, which is within the Molong Volcanic Arc. There are also recordings of small Carboniferous granitic intrusions and capping by Tertiary basalts.
7.3.2. Alteration and Structure
It appears that alteration is locally restricted to that associated with veining i.e. silica-chlorite-pyritesericite (Vassallo J. , 2019b). No porphyry-style alteration assemblages have been identified.
The area is structurally complex, especially the southern and central portions of the tenement, with major structures dominated by east over west thrusts and associated folding. Major faults such as the north-northwest trending McDonalds Hill, Lewis Ponds, and Godolphin Faults, which have been interpreted as east dipping low-angle thrust faults, are present in the southern and central section of the tenement. A seismic line (97AGS-EL2 conducted in 1992) which runs across the tenement and directly through the Dead Horse Creek historical workings, shows these low angle thrusts (Figure 7-2).

7.3.3. Deposit Type and Mineralisation
The tenement is prospective for orogenic gold deposits, similar to the hard rock shear and vein hosted deposits historically mined at Ophir, placer/alluvial and VHMS style mineralisation.
7.4. Resources
There are no recorded Mineral Resources located within this tenement.
7.5. Exploration Potential
The historical workings at Ophir extending over an area of approximately 4 km × 2 km, combined with significant interpreted structures (the main mineralisation is postulated to be shear related) and with the grades reported in historical workings, indicates the economic potential of this area. The potential is likely to be a large tonnage low-grade gold scenario as previous observations and workings have indicated that mineralisation is restricted to narrow shears\veins, which in a modern mining context is difficult to replicate.

Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
Outside of the Ophir mining centre, VHMS deposits have the potential to exist due to the presence of lithologies (Mumbil Shelf Formation) within the tenement that host deposits in other locations nearby. This includes Lewis Ponds (Section 8) and Mt Bulga (historical production of 6.5% Cu). The Drapers Creek and Belgravia prospects are also prospective for VHMS-type deposits. Both of these are within the same stratigraphic and structural setting from the Calula and Larras Lake workings, located approximately 7 km to the north in the Copper Hill East tenure.
Although there is limited recorded outcrop of granitic intrusions, there is still the opportunity for porphyrystyle copper-gold mineralisation being present. The potential for porphyry-style copper-gold mineralisation is considered to be lower and exploration more difficult than for orogenic gold and VHMS styles.
For Mullions, Pine Forest, Lennox Pinnacles and Kitty’s Creek prospects, although some historical workings are present, these are high-level targets and require substantial work to determine prospectivity.
Lower Lewis Ponds is along strike and in the same structural setting i.e. hanging wall of the Lewis Ponds Fault, as the main Lewis Ponds deposit, however previous exploration has been at a very low level and similar to some of the other prospects in this tenement, require follow-up work.
Alluvial/placer deposits have been mined in the past; however, they are expected to be small and of low tonnages and hence in an exploration context, would be considered a low priority.
7.6. Proposed Exploration
The main focus will be to finalise Native Title agreements around the Ophir prospect, investigate soil\stream copper anomalies around Belgrave\Draper’s Creek, Summer Hill Creek\Pine Forest and Dead Horse Gully. The planned expenditure for the reporting period is A$0.06M to A$0.17M (depending upon the total amount raised and progressive results).

8. Lewis Ponds
8.1. Location and Access
The Lewis Ponds Project consists of one tenement (EL5583) which runs in a north-westerly direction 15 km east of Orange and covers an area of approximately 148 km[2] . Access to the tenement is via mainly the sealed White Rocks-Dry Creek-Lower Lewis Ponds roads.

==> picture [30 x 44] intentionally omitted <==
8.2. History
The Lewis Ponds area was an active mining centre from around 1884 till the 1920s. The workings were centred around two major areas; Main Zone (also called Spicers Mine) and Tom’s Zone. Main Zone was actually the site of a smelter and an adjacent limestone quarry – postulated to be a flux source. Spicers Mine was reported to have produced around 6000 t of ore at 6.7% lead and 187 g/t silver (Rowe, 1999). Tom’s Zone was reportedly a pyrite mine and was in operation from 1913 to 1921.
From the field visit by Cube, the workings were noted to be very extensive, consisting of numerous shafts (mostly collapsed) and shallow surface workings. In the southern area, multi-level stopes were observed. The extent of the workings is shown in Figure 8-2. These locations were mapped by Ardea to assist in identifying the surface expression of mineralisation and hence assist in the creation of a geological\mineralisation model.
Around two to three kilometres south of the Main Zone workings, there is another group of workings including; Mt Nicholas, Brittania, Icely and Ophir Copper Mine – recording anywhere from 30-650 t of copper produced (MinView, 2019).
In the western part of the tenement, around Mt Bulga, there is a line of workings and mineral occurrences running over a distance of approximately 6 km. The Mt Bulga Mine was reported to have a copper grade of 6.5% and also has a historical resource from 1970.
In the far northern part of the tenement, west of Summer Hill Creek, there are numerous workings and occurrences around the historical Mt Lindsay copper mine.

8.3. Geology
8.3.1. Setting
The Lewis Ponds deposit lies on the east limb of the Mullions Range Anticline and is hosted within the Late Silurian Mumbil Shelf sequence, part of the Mumbil Group. The actual mineralisation is hosted within the Anson Formation, a fining up sequence from a conglomeritic base to siltstones at the top.
Page | 56
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
The stratigraphic sequence has been metamorphosed to lower greenschist facies (Tri Origin Australia NL, 1999).
Other deposits in the region with similar mineralisation styles include; Daydawn, Calula, Mt Lindsay, Icely and Mt Bulga.
The host lithologies have been divided into three main units. From southwest to northwest and from the bottom of the sequence these are:
-
a) A thick footwall unit of a felsic crystal tuff\sandstone of probable pyroclastic\volcaniclastic origin b) A 100-200 m thick unit of tuff, siltstone, limestone and debris flows that host the main sulphide deposits
-
c) A thick hanging wall massive to laminated siltstone that contains disseminated pyrrhotite
Occasional rhyodacite porphyry and lamprophyre dykes have been noted in the area (Tri Origin Australia NL, 1999).
8.3.2. Alteration and Structure
Within the sulphide lenses, alteration varies in intensity, mineralogy and distribution. Alteration usually consists of varying amounts of chlorite, sericite, carbonate, talc and silica and they either exist with and around the sulphide lenses, as pervasive alteration in the footwall and hanging wall or as foliation parallel zones.
Dip of the zones is generally steep to the northeast, however they can range from vertical to more steeply westerly dipping. This is generally thought to replicate the flexuring noted on the pervasive regional cleavage throughout the deposit.
The most prominent regional structure is the Lewis Ponds Fault, located less than one kilometre to the west of Lewis Ponds, which is interpreted as a splay off the Godolphin Fault. The mineral occurrences at Mt Lindsay also lie in a similar structural setting i.e. within proximity and within the hanging wall of a major regional fault; the Narragul Fault.
Two series of faults have been noted at Lewis Ponds (Tri Origin Australia NL, 1999). One regular set strikes southwest-northeast and dips to the northwest. Mapping has indicated that one of the faults truncates the stratigraphy just to the north of the limestone quarry. The second set are steep dipping and strike east-west. Apart from the fault near the limestone quarry, little offset has been noted.
Other items of interest that were noted during the Cube site visit was the intense deformation, represented by fault gouge and the apparent thrusting and associated minor drag folding within the limestone quarry. From observations it can be concluded that there has been a series of deformation events as a limestone boudin had preserved internal faulting. Also noted, at the southern end of the main Lewis Ponds-Toms Lode line of workings, was a series of workings (“Copper Workings”) trending in a north-south direction i.e. a different to the northwest trending Lewis Ponds mineralisation, that contained copper mineralisation within narrow zones of fault gouge\breccia. Both of these field observations indicate that there is a structural component to this type of mineralisation.
The Little Bell, Brittania and Mt Regan Mines are offset to the east of the Lewis Ponds-Tom’s line. It is unknown if this is due to a structural offset or a stratigraphic offset i.e. copper mineralisation present at Little Bell-Brittania-Mt Regan represents mineralisation deeper in the VHMS pile.
8.3.3. Deposit Type and Mineralisation
The Lewis Ponds polymetallic deposit is a stratabound and disseminated sulphide system and is historically considered to be of a VHMS type. Godolphin has documented a later stage deformation and
Page | 57
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
an orogenic overprint that has introduced a component of remobilisation and the introduction of silica respectively into the system, as well as flexuring of the stratigraphy. This was noted by Cube during the site visit and also by Agnew (2002). The later stage fluid inflow was best observed around the Torphy’s workings where bladed quartz structures with copper staining was found. The historical concept of synformal structures being present, resulting in the folding of one of the footwall lenses has now been discounted.
Agnew (2002) concluded that Tom’s Zone was a sheet style VHMS deposit formed at or near the sea floor, which has later been deformed, remobilised and fluids introduced by the Lewis Ponds Fault. The Main Zone however has similarities with carbonate-hosted replacement deposits, where sulphides have infiltrated into the pore spaces of poorly sorted breccias. Textures within the sulphides indicate rapid sea water quenching.
Previous workers (Tri Origin Australia NL, 1999) have described the mineralisation consisting of three main domains; the massive sulphides of the Main Zone and Tom’s Zone and the Footwall Stringer Mineralisation. A brief description of these is as below:
-
Main Zone – consists of three sub-parallel sulphide lenses (Central, Hanging Wall and Footwall Lenses). The Central and Hanging Wall Lenses are around 15 m and 4 m thick respectively and consist of alternating zones of massive to semi-massive sulphides interspersed with disseminated stringer zones (Figure 8-3). The Footwall Lens is approximately 18 m thick, consisting of a sulphide matrix within a tuffaceous and limestone clast host. Mineralisation consists of massive pyrite, red-brown sphalerite, galena, chalcopyrite, pyrrhotite, tetrahedrite and gold – both as native and within pyrite.
-
Tom’s Zone – consists of one massive sulphide lens (Figure 8-4) that is approximately 5 m thick and a current strike length of 300 m. Tom’s contains higher grades of base metals but lower gold grades compared to Main Zone.
-
Footwall Stringer – located south of Tom’s and is characterised by copper mineralisation hosted in quartz-chlorite-chalcopyrite veins, stringers and disseminations. These were noted at Little Bell and further south at Brittania and Mt Regan.
Although three main domains have been identified (as described above), there are also lessor concentrations of disseminated sulphides present locally between the main sulphide lenses. These zones have been identified and modelled in the 2019 Mineral Resource Estimate. This is expanded on in Section 8.5.

8.4.1. Drilling
Drilling has been conducted at the Lewis Ponds Project since the late 1960s, with various minor programs carried out in 1973 (Amax), 1986 (Homestake), 1989 (Sabminco), before more intensive drilling was carried out from 1991 through to the present by Tri Origin\TriAusMin. Over 200 hundred holes have been drilled in and around Lewis Ponds with around 75% of the holes being diamond. The latest program, drilled in February-March 2017 by Ardea, consisted of four holes, mainly drilled to obtain samples for metallurgical testwork, but were also assayed. To assist in updating the geological model, these holes and other older holes on the same section (where suitable quality core still existed) were logged in a geological, mineralogical and structural context.
8.4.2. Metallurgical Testwork
Material obtained from four PQ\HQ diamond drillholes (ALD0001-ALD0004) that were drilled in February-March 2017 at 200 m spacings through the deposit, was submitted to SGS (Perth) for metallurgical testwork. This was completed and reported in late 2018.
The testwork showed that an initial dense media separation (DMS) at a relatively large crushed particle size (-12.5 mm), over 90% of the sulphide and precious metals are recovered, on top of 25% of the material being rejected (Reynolds, 2018). DMS is a method that could be applied to ore feed that rejects lower grade or gangue material and hence allowing for higher grade process plan feed material or a lower mine cut-off.
Testwork indicated that two concentrates could be produced via gravity and flotation methods. The zinc concentrate contained 66% zinc and 64 g/t silver for 80% zinc recovery, while the second Cu-Pb concentrate contained 30.3 % lead, 4.78% copper, 1,619 g/t silver and 17.6 g/t gold for 70.3% lead recovery and 61.8% Cu recovery (Reynolds, 2018).
The metallurgical testwork concluded that:
-
The flotation process is expected to be relatively simple
-
The testwork material contained low talc
-
A fine re-grind size (20-35 µm) may be required to liberate acceptable levels of galena (lead)
-
A moderate grind size (40-60 µm) would be required for sphalerite (zinc) liberation
-
Gold preferentially deports to copper-lead concentrate
-
Intervals within ALD0001 (75-93 m and 110-122 m) showed poor zinc and lead recoveries respectively.
Cube notes that all the material submitted for testing was classified as ‘fresh’, therefore recoveries in the higher (oxide) portions, which has the potential for lower recoveries, has not been metallurgically tested. Although analysis of sulphides from the thin oxidised layer only showed minor mineralogical differences to sulphides in the fresh zone, which could imply no significant effect on recoveries, Cube recommends further metallurgical testing, both in the oxide zone and further confirmation testing in the fresh zone particularly in light of some intervals from ALD0001 showing poor recoveries.
More historical testwork was carried out by Amdel (1994 and 1995) and Metcon (1995) on two diamond holes. However, a different process route was being tested at that time (cyanide leach for gold, followed by flotation), so comparisons between the two series of testwork is not possible. The testwork did indicate that only approximately 54-74% of the gold could be extracted by gravity followed by cyanide leach, indicating a proportion of the gold is locked up in sulphides ( (Amdel Ltd, 1994) and (Metcon Laboratories Pty Ltd, 1995)).

8.5. Resources
Mineral Resource Estimates have previously been reported in 2005 and 2016. No additional drilling was included in the 2016 update, however the Mineral Resource was reviewed and updated to comply with JORC (2012).
The revised 2019 Mineral Resource Estimate (Table 8-3) is based on and assisted by further work that was completed after the 2016 estimate. This included:
-
Four equally spaced (200 m apart) diamond drillholes drilled along the strike length of the Lewis Ponds deposit
-
A re-logging campaign of selected diamond core
-
Modification and standardisation of historical geological logging
-
Drill database validation
-
Field mapping and spatial location of underground and surface workings.
The above points assisted in refining the geological model in preparation for an updated Mineral Resource Estimate.
The 2019 Mineral Resource Estimate was divided into an open pit Resource and an underground Resource. Figure 8-3 and Figure 8-4 tabulates the open pit and underground Resource respectively

The following is a summary of the data, parameters and methodology used in the 2019 Mineral Resource Estimate:
- The Lewis Ponds deposit occurs within the Anson Formation, which is part of the Mumbil Group. The Anson Formation consists of a fining upwards sequence with conglomerate at the base and finer siltstone at the top. The sequence dips steeply to the north-east or sub-vertically. A mineralisation model was created consisting of massive sulphide and disseminated domains.
7 In accordance with the Australian Security Exchange Limited Listing Rules Appendix 5A. The information in this report that relates to Mineral Resources for the Lewis Ponds Project has been reviewed, and verified by Mr Johan Lambrechts who is a full time employee of Ardea Resources Ltd. Mr Lambrechts who is a Member of the AIG, takes responsibility for the integrity of data that have been used to prepare the resource estimates, and for the Geological Model. Mr Lambrechts has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the resource estimation activity that he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the JORC Code: Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Lambrechts consents to the inclusion in this report of the matters based on his information in the form and context that it appears.

There were seven massive sulphide domains and eight disseminated domains. The disseminated domains were interpreted using a dual approach of interpreting on zinc and gold equivalent values, while the massive sulphide domains were mainly based on where logging identified massive sulphide. As mentioned earlier, there are considerable drillhole intervals that have not been sampled, therefore the construction of the geological mineralisation model using the afore mentioned parameters was problematic in some areas
-
Sampling was generally conducted on one metre intervals. RC drilling samples (3-5 kg) were collected by spear sampling and for DD half-core was sampled.
-
The Mineral Resource Estimated was conducted using a dataset of 213 drillholes for a total of 63,335 m. This dataset consisted of 58,425.44 m of DD and 4,909.2 m of RC. These were drilled in various campaigns from 1971 to 2017.
-
The Indicated Open Pit Resource is generally defined as areas with 50 m × 40 m or closer drill spacing with a kriging slope of regression of ≥0.70 and an average distance to composite data of 40 m – 50 m. The Inferred Open Pit Resource is defined by wider spaced drilling and limited by a digital terrain model defining the base of reasonable expectations of economic extraction and where sufficient drilling confidence exists that the continuity of geology and mineralisation can be extended. The Inferred portions of the Mineral Resource has an average kriging slope of regression of 0.4 to 0.5 and an average distance to informing composite data of 70 m – 80 m. The Underground Inferred Mineral Resource is classified as such due to the less continuous nature of the lodes and wider spaced drilling resulting in composite date being >75 m and kriging slope of regression of 0.22. Any areas with better parameters than this are classified as Indicated. No depletions to the Resource was undertaken to take into account the historic underground workings.
-
The only information available on sample analysis was for the 2004 drilling campaign where gold was analysed on a 30 g sample using fire assay. Silver, copper, lead and zinc were analysed by aqua regia digestion followed by AAS.
-
Ordinary Kriging estimation methodology was applied to the 15 individual domains and to the five grade attributes. Relevant search ellipses and kriging parameters were applied for each grade attribute. Drill hole assay data were composited to a uniform one metre density weighted length (best fit methodology) for geostatistical analysis and estimation. Parent block sizes used were 20 m (Y), 10 m (X) and 10 m (Z) with sub-blocking of 5 m (Y), 1.25 m (X) and 2.5 m (Z).
-
Separate cut-off grades were used for the Open Pit and Underground Mineral Resource Estimates – both being based on zinc equivalents (ZnEq). The Open Pit and Underground Mineral Resource are reported at a cut-off of +1.0% and +3% ZnEq respectively. The ZnEq calculation is calculated by the following equation and assumptions:
ZnEq = Zn% + (Au ppm × 1.949) + (Ag ppm × 0.019) + (Cu% × 2.306) + (Pb% × 0.741)
-
Listed commodity price assumptions as of 31 July 2019 are combined with estimated metallurgical recovery proportions as follows:
-
Zn – US$2585/t, 80% recovery,
-
Au – US$1393/oz, 90% recovery,
-
Ag – US$15.50/oz, 80% recovery,
-
Cu – US$5960/t, 80% recovery,
-
Pb – US$1915/t, 80% recovery.
-
The selection of 3% ZnEq cut-off (underground) corresponds to US$77.55 per tonne or A$115.75 per tonne in situ value (at 1 A$ = 0.67 USD). The in-situ value at 1% ZnEq cut-off (open cut) is A$38.58.
-
The Open Pit Mineral Resource is constrained by a preliminary pit shell generated in Whittle software. The shell has been defined using the calculated ZnEq (as discussed within the above
Page | 65

==> picture [30 x 44] intentionally omitted <==
cut-off grade section) together with an assumed A$30/t processing cost and A$4/t mining cost with 45° wall slopes. A shell showing a revenue factor of 1.9 was selected to limit the reporting of these Mineral Resources to within reasonable expectations of future economic extraction by open pit method. Within this shell, the model was subjected to a 1% ZnEq cut-off, whereas those portions of the model below the pit shell were subjected to a 3% ZnEq cut-off. Metallurgical testwork has shown that an initial dense media separation (DMS) at a relatively large crushed particle size (-12.5 mm), over 90% of the sulphide and precious metals are recovered, on top of 25% of the material being rejected. Testwork indicates that two concentrates could be produced via gravity and flotation methods, producing a zinc concentrate containing 66% zinc and 64 g/t silver for 80% zinc recovery and a copper-lead-silver-gold concentrate containing 30.3 % lead, 4.78 % copper, 1,619 g/t silver and 17.6 g/t gold for 70.3 % lead recovery and 61.8 % copper recovery.
Cube has reviewed the above assumptions and has concluded that they are appropriate. For a more detailed explanation of the Lewis Ponds 2019 Mineral Resource Estimate, readers are directed to read the Ardea ASX release dated 3[rd] September 2019 (Ardea Resources Ltd, 2019c) or to Appendix 4 in this report.
8.6. Exploration Potential
The potential to increase the Lewis Ponds Mineral Resource is considered to be high. Further infill drilling and drilling along strike not only has the potential to increase, but also to improve confidence in the Mineral Resource. There is the potential to increase the amount of contained gold as there are a considerable number of holes that intersect the interpreted domains that were not sampled for gold; for the Mineral Resource Estimate these intervals were assigned a gold grade of 0.0001 g/t. As well as the unsampled intervals, there are at least two obvious massive sulphide domains that are open at depth, as shown in Figure 8-5. A more thorough investigation of the block model in relation to existing drilling will have a high chance of identifying potential drill targets that may lead to increasing the Resource.

Historical workings within the immediate Lewis Ponds vicinity, from Mt Regan Mine (recorded production of over 8 t of copper and 4.9 t of zinc) to New Lewis Ponds runs over a distance of around 5 km, which highlights the potential strike of the mineralisation. A percussion hole drilled by Shell in

1982 below the Little Bell Mine (1.2 km southeast of Tom’s) intersected 22 m @ 0.2% Pb and 0.45% Zn, further highlighting the extent of the mineralised system. Drilling from Little Bell Mine to Summers Mine to the north is scarce and wide spaced. Recent rock chip sampling carried out by Ardea between Little Bell Mine and Summers Mine confirms the extent of the mineralisation (Ardea Resources Ltd, 2019d).
The southern section of Lewis Ponds, around Summers Mine and “Copper Workings”, shows higher copper values and this was confirmed from field observations of noted copper mineralisation. Although these copper occurrences appear to be structurally related, it could indicate a closer proximity to the feeder zone. More detailed geochemistry work may assist in vectoring in on feeder zones.
Although Ardea has completed a re-logging campaign on four drill sections, further benefit could be gained from further re-logging, as a large amount of historic diamond core is still stored on site. In conjunction with this, re-submitting core for assay – mainly the disseminated mineralisation, as the massive sulphide intersections would be too degraded to obtain meaningful assay results – would also be helpful, as there are significant downhole widths of core that were not assayed. This become apparent during the 2019 Mineral Resource update and as a result hindered the creation of a new geological model and subsequent estimate.
Ophir Copper Mine, Icely Mine and Mt Nicholas (650 t of copper produced) which are located over 6 km to the southeast of Tom’s Lode, all lie within Mumbil Group which is the same host as Lewis Ponds. They also lie within a structurally complex zone of fault splays off the Lewis Ponds Fault. The fact that Icely Mine and Mt Nicholas, which have historic production of 508 t and 650 t of copper respectively, plus that the Icely Mine has noted stacked sulphide lenses (MinView, 2019) and drill intersections of 1.8 m @ 4.21% Cu and 3.2 m @ 3.99% Cu (Shepherd, 1972), highlight the potential of this area.
The Mount Lindsay prospect, located at the northern end of EL5583, is contained within the prospective Mumbil Group. Previous exploration activities do indicate the presence of narrow massive sulphide bodies. Gossanous outcrop with anomalous copper-lead-zinc has been observed and historical records from the Government Geological Surveyor in 1935 described 30 m deep shafts and conformable sulphide bodies (Kamilaroi Oil Co Ltd, 1971). Around 20 diamond holes drilled were drilled in the early 1970s. Significant intersections were found e.g. ~2 m at 1-6% Zn but were generally narrow and scattered (Kamilaroi Oil Pty Ltd, 1973), however recoveries were poor in noted zones of mineralisation. Further drilling in 1978 (Kamilaroi Mines Ltd, 1979) intersected similar narrow intersections of copper mineralisation of > 1%, but no significant zinc values were reported. Although it appears that later stage exploration activities in the Mt Lindsay area has been limited, further literature searches are required to fully evaluate this area.
8.7. Proposed Exploration and Further Studies
Diamond drilling at Lewis Ponds is planned to increase confidence in the Mineral Resource model and update the geological model. It has been suggested to drill horizontal or near horizontal holes through the whole sequence as previous drilling has not really achieved a complete cross section through the complete mineralised sequence. Cube concurs with this idea and logistically this is easily achievable due to topography and the availability of underground drilling rigs in the Orange-Parkes area.
Depending upon land access negotiations, mapping, rock chip sampling and general reconnaissance is planned for the Mt Lindsay and Mt Nicholas/Icely/Ophir/Williams Lode areas.
Due to the very extensive work in the area, and other areas within the Godolphin portfolio, that has been undertaken since the late 1960s, the MinView database contains a wealth of information that requires a thorough review to assist in targeting areas and avoiding doubling up of work programs. This is especially the case for the Mt Lindsay and Mt Nicholas/Icely/Ophir/Williams Lode areas.

Due to the location of Lewis Ponds and adjacent properties, Cube recommends that Godolphin commence environmental and social impact studies in conjunction with the above planned exploration activities.
Godolphin has proposed a budget of A$0.79M to A$1.51M (depending upon the total amount raised and progressive results) for the current reporting period.

9. Wisemans Creek
9.1. Location and Access
The Wisemans Creek Project (Figure 9-1) consists of the tenement EL8554, which is around 229 km[2] and is centred around the town of Oberon. It is approximately 130 km west-northwest of Sydney.

Page | 69
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
9.2. History
This area has a long history of mining, with numerous historical workings and numerous commodities being exploited including; gold, copper, tungsten, molybdenum, lead, zinc and silver.
9.3. Geology
9.3.1. Setting
The region contains elements of the Ordovician-Early Silurian Macquarie Arc, Early Devonian Hill End Trough and Carboniferous Intrusions (Vassallo, J, 2019a).
The Tarara granite (part of the Carboniferous Bathurst Batholith) forms an arcuate belt within the far northern part of the tenement. Other granites of the Bathurst Batholith (Oberon and Duckmaloi granites) have intruded into the southern and eastern part of the tenement. Belts of sediments and volcanics of the Macquarie Arc and Hill End Trough are interspersed between the intrusives.
In the eastern part of the tenement, there is a 10 km wide corridor of north-northeast trending narrow dyke-like features. These features extend approximately 20 km north and south of the tenement boundaries (MinView, 2019). It appears that these have been interpreted from regional magnetics, but ground truthing confirmation of these is limited with the only noted occurrence of these appearing in the literature is at Copper Hill, where they have been described as leucocratic or dolerite dykes.
9.3.2. Alteration and Structure
The main structural fabric is north-south trending, with faults, thrusts and isoclinal folds formed due to the compression and closure of the sedimentary basins.
Numerous alteration styles have been noted on this tenement, dependant on the mineralisation style. A review of Landsat (Vassallo, J, 2019a) imagery noted stronger iron oxide alteration within the eastern part of the tenement and the western part of the tenement being dominated by alumina-magnesium minerals.
9.3.3. Deposit Type and Mineralisation
There are many mineralisation occurrences and styles scattered throughout the tenement. The location of major mineralisation occurrences is shown in Figure 9-2 and these are summarised in Table 9-1.

9.4. Resources
There are no recorded Mineral Resources located within this tenement.
9.5. Exploration Potential
The Duckmaloi prospect has potential for both skarn-type tungsten-bismuth and mesothermal gold mineralisation, all related to the circular Duckmaloi granodiorite. The potential is highlighted by:
-
There has been several other noted mineral occurrences on or close to the contact between the granodiorite and the Karawina Formation.
-
The presence of limestone quarries (MinView, 2019) indicate favourable lithologies for skarn development.
-
Significant historical production of bismuth (1.3 t according to available records)
-
Drilling of known skarns by Australian Ores and Minerals in the early 1970s returned an intersection of 8.6 m @ 0.49% WO3 and also recorded molybdenum stream anomalies.
-
Shell Australia drilling in the mid to late 1980s intersected 24 m @ 0.18% WO3 and 10 m @ 0.28 WO3.
Previous workers have noted that the skarns in this area are probably limited in extent, but further work is warranted.
Fitzpatricks Reef also has some noted similarities to the Duckmaloi prospect. Duckmaloi, Fitzpatricks Reef and other noted mineral occurrences in the southeast corner of the tenement, are located on or adjacent to the north-northeast dyke-like structures identified on regional magnetics (Section 9.3.1). This relationship warrants further investigation to determine if these linear structures are dykes or structurally related.
Fitzpatricks Reef and the area just to the northeast, close to the tenement boundary (also located on a north-northeast trending strong magnetic response) show strong anomalism in gold stream sediments, however lead, copper and arsenic stream sediment signatures are more concentrated around Fitzpatricks Reef itself.
Black Bullock has strong reasonably large gold and arsenic anomalies in stream sediments, however base metals appear to be of a lower degree and more restricted (Vassallo, J, 2019a). Due to the degree of historical mining activities and the potential for sediment dispersion from these areas, some caution needs to be applied to these results. Reasonably extensive drilling by BP Minerals, Central Western Gold and others returned mixed results, but with around 10 holes returning significant gold intersections of greater than 10 m downhole, this requires further investigation. Due to the heavily forested nature of this area, this will limit ground truthing and investigation and hence a full review of available data will need to be carried out before more targeted exploration commences.
The Libby prospect area is contained within the Campbells Group sediments and in conjunction with exploration results is prospective for VHMS-style mineralisation. This area contains a series of minor workings spread over an area of approximately 2 km[2] . Sampling of a 2-3 m outcropping mineralised zone returned 2800 ppm copper, 560 ppm lead, and 8400 ppm zinc. Soil sampling, ground magnetics, IP and EM indicates that mineralisation is of limited extent, however confirmation of this has not been tested by drilling. Therefore, a targeted first pass drill program after further data compilation and review will assist in determining priorities in relation to other prospects in the tenement.
Diamond Hill, which sits close to the contact of Tarana Granite and Rockley Volcanics, is prospective for skarn and mesothermal type deposits. A zone of workings over 150 m in length is present and rock chips taken in this area indicate the presence of base metal mineralisation associated with a skarn.
Page | 73
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
Mapping has indicated that the skarn may exist over a length of around 350 m, however further groundwork is required to confirm the extent of the skarns.
There are no recorded historical workings with the Lowes Mount prospect area, however it does lie within a similar stratigraphic setting as the Copper Hill skarns i.e. on the contact between Tarana Granite and Rockley Volcanics. The area has one of the strongest gold stream sediment anomalies within the whole tenement and a strong copper anomaly. Due to the limited work, prospectivity is hard to determine at this early stage.
Mt Reeves, Deep Creek and Titania, located in the far south-eastern corner of the tenement, close to the Duckmaloi Granite, are low level targets requiring follow-up. Mt Reeves and Deep Creek have minor single workings, with Mt Reeves having a recorded rock chip sample of 0.15% zinc. All have stream sediment gold anomalies, but Mt Reeves also has copper and lead anomalies.
Essington and Oberon prospects in the southwest corner of the tenement are located within the Rockley Volcanics. There is a recorded instance of minor historical workings located at the Oberon prospect, with an adjacent rock chip sample returning 0.3% copper and 12.2 g/t gold. There is also potassiumthorium-uranium radiometric anomaly centred on the recorded workings, however these workings are actually located just within an adjacent tenement (EL6525) held by another party. Due to the interpreted structures and noted mineralisation style, this occurrence is most likely structurally controlled. Both prospects have weak steam sediment anomalies.
Other areas identified as being prospective (Vassallo, J, 2019a) include Spring Water Creek and Homeward Bound. Due to these being close to the town of Oberon and associated infrastructure these are not considered to be targets at this stage.
9.6. Proposed Exploration
A portion of the Wiseman’s Creek tenement is Crown Land. Access to this land will be through the process of “Right to Negotiate”. The highest priority activity planned is mapping and rock chip sampling over the Black Bullock prospect. Ground reconnaissance in other areas are also planned. A total expenditure of approximately A$0.13M to A$0.25M (depending upon the total amount raised and progressive results) for the reporting year has been proposed.

10. Calarie
10.1. Location and Access
The Calarie Project consists of the EL8555, EL8580 and ML739 tenements covering an approximate area of 137 km[2] . The tenements run from just north of Forbes in a north-easterly direction ending approximately 7 km to the southwest of Parkes (Figure 10-1). The Newell Highway bisects the tenements.

Page | 75
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
10.2. History
This area has a long history of mining, with the most significant being the London-Victoria gold mine and processing plant (which processed ore from the Mt Aubrey BHP open pits mined in 1990) located just to the north of the tenements.
In a more historical context, there are numerous workings located throughout the tenement, with major groupings of workings centred around the settlement of Calarie and the more modern London-Victoria Mine. All workings appear to be gold associated with a strong structural component.
10.3. Geology
10.3.1. Setting
Two main rocktypes exist within the Calarie Project area (Ostrowski M. , 2019b). These include:
-
Parkes and Nash Hill Volcanics of the Ordovician Junee-Narromine volcanic arc (which hosts Northparkes porphyry copper deposit some 40 km north)
-
Intermediate volcanics (Daroobalgie Volcanics, Cotton Formation, Calarie Sandstone, Bocobidgle Conglomerate and Mugincoble Chert) of the Ordovician-Silurian.
The project area is contained within the north-south trending Forbes-Parkes Belt, which forms part of the larger Junee-Narromine Volcanic Belt.
10.3.2. Alteration and Structure
The generalised style of alteration noted within and adjacent to the mineralisation zones are low temperature albite-sericite-carbonate-chlorite-quartz ± pyrite assemblages. Within or close to the mineralisation pyrite-pyrrhotite-silicification assemblages become more common. Alteration zones appear to be conducive to detection by IP methods.
The deposits within this area are generally restricted within two northeast striking bounding faults which form part of the Parkes Fault System. They occur on these structures or linking structures of various orientations within this faulted domain (Figure 10-2).

Figure 10-2: Interpreted structures within the Calarie Project (Source: (Ostrowski M. , 2019b))
10.3.3. Deposit Type and Mineralisation
Deposits in the area are considered to be of a structurally hosted orogenic type. They occur either as saddle reef type quartz veins within the Cotton Formation or along favourable contacts between the volcanics and fine-grained sediments.
10.4. Resources
There are no current reportable Mineral Resources located on this tenement.
Page | 77
Godolphin Resources Ltd New South Wales Gold and Base Metal Projects
==> picture [30 x 44] intentionally omitted <==
10.5. Exploration Potential
All prospects identified lie within the Parkes Fault Zone. This zone contains a very concentrated cluster of mineralisation occurrences and historical workings. There appears to be two main grouping of occurrences within this zone – both related to northwest trending cross cutting fault zones. One cross cutting zone is at the southern end of the tenements and one to the north which is outside the existing tenements.
The Calarie Project is considered to be the high priority walk up target, primarily due to extensive underground workings and the reported grades extracted. There is considerable evidence that the mineralisation extends below and along strike of the existing workings. In some cases, previous drilling has failed to intersect the prospective zones. Future drilling would have to be carefully targeted as it appears there are discreet lodes\shoots with a plunge component.
The prospects of Wattlegrove, Bald Hill and Pinehill occur along the same strong magnetic anomaly that hosts the Calarie deposit and hence the prospectivity is encouraging. Wattlegrove has reported some encouraging drill results which warrant further investigation. Combined with the potential of Bald Hill, due to the potential of structural traps and presence of chemically receptive limestones, the area directly along strike is considered prospective. It is believed that due to the cover around the Bald Hill prospect, previous exploration activities may not have been appropriate.
The more western and northern prospects (Nibblers, McMillan’s, McGraths, Mary’s Dream and MagpieStaples) are considered to have lower prospectivity due to:
-
Their location off the main mineralised Calarie trend.
-
Their distance away from the northwest cross-cutting structures within the Parkes Fault Zone that appear to show concentrated mineral occurrences.
-
Distance from the postulated fluid conduit of the Parkes Fault.
Parkes Fault West is a conceptual target only as it is close to the postulated fluid source structure of the Parkes Fault.
10.6. Proposed Exploration
Proposed exploration activities are heavily based on gaining land access. If this is achieved, it is planned to commence soil sampling around the Wattlegrove, Calarie and McMilliams Trend areas and evaluate the potential for ground magnetic programs. A total expenditure of around A$0.15M to A$0.26M (depending upon the total amount raised and progressive results) is planned.

11. Gundagai
11.1. Location and Access
The Gundagai Project consists of two tenements – EL8061 (Gundagai South) and EL8586 (Gundagai North) which cover an area of approximatley 278 km[2] and one tenememt under application (ELA5809). EL8061 runs from the southern limits of the township of Gundagai for approximately 25 km to the south (Figure 11-1), while EL8586 is centred about 15 km to the north-northeast of Gundagai (Figure 11-2 and Figure 11-1). Ardea ELA5809, centred around the Gundagai townsite, links EL8061 and EL8586.

11.2. History
The area has long history of mining and prospecting. The first gold rush within the Gundagai and Adelong area was recorded in 1848, based on both alluvial and outcropping veins. The GundagaiAdelong goldfield was considered to be within the top ten producers for the period from 1848 to mid1900s (Hatfield, 2007). There were numerous small mines previously worked for gold, copper, lead, zinc, chromium, magnesite, barite and manganese. There have also been noted occurrences or

exploitation of asbestos, silica and talc. Significant producers include; Califat (37 t copper), McAlpine (5 t copper), Mt Mary (406 t chromite), Princess Marina (20 kg gold) and Big Ben alluvials. The mineral rich nature of the area can be seen in Figure 11-3, which shows recorded mineral occurrences. At the present time there are no current mining activities taking place in the area.

11.3. Geology
11.3.1. Setting
Rocks within the tenement consist of the Cambrian to Silurian oceanic crest, Early Silurian Tumut Trough and Late Ordovician Molong Volcanic Arc, all part of the eastern Lachlan Fold Belt. The oceanic crustal material includes; serpentinites, basalts and cherts. The Tumut Trough material is characterised by felsic volcanics (Frampton Volcanics), feldspar porphyry intrusives and basinal sediments like the Jackass Slate. Early Devonian uplift was accompanied by felsic intrusives and rhyolitic volcaniclastics (Vassallo J. , 2019c).
Late stage alluvial and colluvial cover sediments (part of the Tertiary Murray-Darling Basin) are present, mainly along and adjacent to the Murrumbidgee River.
11.3.2. Alteration and Structure
Overall the area sits within the north-northwest trending Tumut Synclinorial Zone which is bounded to the east by the Mooney Thrust and to the west by the Gilmore Fault (Suture) Zone.
Most of the alteration noted by previous workers was alteration associated with porphyritic intrusions. This ranges from high temperature potassic and phyllic alteration through to chlorite-sericite-carbonate alteration. Other noted alteration assemblages described include; calc-silicate and chlorite-actinoliteanthophyllite-magnetite-biotite-quartz associated with thick lenses of sulphide.
11.3.3. Deposit Type and Mineralisation
Most of the gold deposits in the region have been classified as orogenic or shear hosted. Later workers have postulated that some of these deposits, due to the relationship with porphyry dykes and the presence of quartz-biotite veins, are in fact Intrusion Related Gold Systems (IRGS). The base metalgold deposits are considered to be VHMS.
11.4. Resources
There are no current reportable Mineral Resources located on this tenement.
11.5. Exploration Potential
Historical mining activity and recent exploration has shown that the Project contains numerous mineralisation types. These include; orogenic gold and/or IRGS, hydrothermal gold, porphyry hosted copper-gold, alluvial gold and VHMS.
Previous work carried out around existing workings tends to show that mineralisation in these areas is narrow and of limited extent. However, the potential exists for deeper large tonnage lower grade orogenic and/or IRGS gold systems, especially around porphyries that show alteration assemblages that are indicative of these styles of mineralisation. Detailed analysis of multi-element geochemistry will assist in targeting the more prospective areas.
Recent activities conducted by Ardea around the Big Ben Trend have highlighted anomalous gold and copper values with an associated manganese oxide overprint. This area will be one of the highest priority targets within this Project.

11.6. Proposed Exploration
Godolphin plans to conduct field activities such as; mapping, rock chip sampling and soil sampling in areas where access has already been granted. The highest priority will be to conduct further soil auger around the Big Ben area, following up previous anomalous auger and rock chip results. Activities in other areas will be dependent upon gaining land access. Approximately A$0.13M to A$0.26M (depending upon the total amount raised and progressive results) is planned to be spent in this reporting period.

12. Social Considerations, Environmental, Native Title and Land Access Issues
Within recent years some mining activities within NSW, especially those involving coal and coal seam gas, have had significant negative publicity, with the flow-on effect that some proposed mining operations were not able to proceed. It is now imperative for any project in NSW that the leaseholder be open, transparent and engaged with the local communities. Ardea has engaged a contract Community Liaison Officer who will continue to assist Godolphin in accessing land for exploration activities, to keep local communities informed and provide publicity on the positive economic effects of a mining operation. This will expand once exploration activities ramp up.
Most areas within the Godolphin tenements would be considered to be closely settled, with land ownership ranging from reasonably large agricultural enterprises to small lifestyle blocks. It appears that a considerable number of landholders would need to be consulted to request permission to access and carry out exploration activities. Cube’s review of previous exploration reports noted several instances where the then tenement holder stated land access issues. Newmont stated in a 2014 exploration report that failure to gain access to parts of their tenement contributed to them dropping that particular tenement. Land access issues were also noted in the Calarie tenements. That said, it is uncertain whether these particular land access issues are still relevant to the current tenements. Although land access can pose problems, they are not insurmountable and again the engagement of the Community Liaison Officer will assist with this. Recent work carried out by Ardea and the nearly 30 land access agreements that have already been confirmed shows that the company has a good relationship with certain landholders and there is no reason why this could not extend to other landholders.
Further exploration, for example drilling around the Lewis Ponds deposit will not be hindered as the deposit is within land owned by TriAusMin Pty Ltd (currently a subsidiary of Ardea Resources Ltd), therefore this Project stands out as a good walk-up target. If the results of further drilling, Mineral Resource updates and economic studies are positive, considerable thought will need to be given to potential waste dump locations and how mining activities could impact on neighbouring properties, as the Lewis Ponds deposit lies on the side of a hill which is visible to numerous dwelling and farming properties.
Native title access is still being negotiated for parts of the Ophir and Wiseman’s Creek Projects. Currently this affects approximately 20% of both tenements.
The Wisemans Creek Project also contains several state forests. Negotiations to access these areas are currently underway.
The main area of the historic Ophir gold workings has a cultural and historical significance associated with it as it is the site of the first recorded gold rush in Australia. There is a historical walk and park with notice boards around Lewis Ponds Creek to signify this aspect. Despite this public area being the site of original mining operations and being located adjacent to recent semi-active small-scale mining operations, any disruptive exploration around this immediate area is most likely not possible, however this represents only a small proportion of the total tenement area.
As previous mining activities tended to be small scale, Cube is unaware of any environmental liabilities such as acid mine drainage, tails dams or other associated items on any of the tenements held by Godolphin.

• The historic reports do not all specifically mention sub-sampling techniques, but it is assumed that the RC, RAB and aircore drilling rigs were equipped with a cone or multitier riffle splitter attached to the cyclone, or a separate multitier riffle splitter was used alongside the drill rig by BHP and YTC field staff. The splitter generally provided one bulk sample of approximately 10-20kg and a sub-sample of 2- 4kg per metre drilled. • Bulk samples were collected in plastic bulk bags, with the sub-samples collected placed in calico sample bags. The drilling technique was sufficient to keep the majority of bulk samples collected dry and sufficiently representative of the intervals being drilled. Any wet samples or poor recovery were noted on the logs that were updated at the drill rig by the supervising geologist. • The drill chips from the RC, RAB and aircore holes were mostly riffle split at the rig with the sample bagged for transport to the analytical laboratory. Some spear sampling may have been completed for moist and wet samples. Sample splitting was considered to give a satisfactory representative sample of the bulk bags. The quality of the split sample is assumed appropriate based on the reputation of the companies performing the sampling including BHP Gold Mines and YTC Resources. Both BHP and YTC Resources used qualified geologists at the drill rig during drilling and sampling ensuring a high standard of work. • Sample size was not reported for all intervals drilled and collected, however satisfactory considering the level of supervision.

| 0.5m length to 2m lengths to accommodate changes in geology and mineralisation. Cutting and sampling of the core was supervised | ||||

The collar in the hanging wall of the main pit was validated by finding 8 collar locations. The collars in this part of the resource were found to have an error of 2.24m East and -5.64m North. The error margin for the collar surveys can only be confirmed in these two locations and is considered acceptable for an inferred resource. Further drilling is planned for the near future and these collars will be surveyed via differential GPS. The data obtained from this and other future drill programs will be used to further validate historic data.

| | The collar data South of the main pit showed a larger error margin. | |||
| The discrepancy is 2.24m East and 5.64m North (See image below.). | ||||
| This error could be validated using eight (8) collars still available in | ||||
| the area, but the remainder have all been destroyed by the mining of | ||||
| the open pit, or by agricultural activities such as ploughing the field to | ||||
| the south of the pit for cultivating crops. The resultant potential shift | ||||
| in the mineralization due to the shift in collar location has been | ||||
| checked in three dimensions and is deemed insignificant relative to | ||||
| the scale of the interpreted geology (See image below). It’s localized | ||||
| status also increased the confidence instating the overall impact on | ||||

oThe down hole survey data was visually checked and validated and found in order.oThe assay data could not be validated with lab certificates since none have been found in the historic records. The average grade represented by the assay data however corresponds well with the historically reported grade of the mine during operation, giving increased confidence in the integrity of the data. -
oRAB Holes: During the Mount Aubrey Resource Estimation 31 RAB holes were used as part of the geological modelling and estimation phase. The RAB hole were drilled in 1990 and targeted the Main Pit mineralised veins predominantly. The mining of the historic pit effectively depleted the RAB intersections (See table below), but due to the low number of RC drill intercepts in vicinity of the RAB holes in the North Western part of the pit especially (See Image below), and the relatively small number of RAB holes compared to the 157 RC holes, the RAB holes were used during the estimation process.

The data acquired from reports stating the 2-8m variability of the quartz vein thickness was also used as guides for the geological
interpretation.
Due to the sparse data available along strike and down dip of the historic pits, the veins were also pinched if no data was available within
40m of the last data point.

The first having the range of the variogram model in each direction as its |
|
| distance parameters, the second has 1.5 times that range and the third has twice the range distance as search ellipse. The | |||
| minimum number of samples for each pass is 10 and the maximum is 20. In addition, each drill hole could only contribute 5 | |||
| samples to the estimation of any block resulting in the required use of at least two drill holes with 5 samples each to the | |||
| estimation of grade for any block. No top cuts were applied. The inverse distance interpolator was also set to assign maximum | |||
| weight to samples closes to the centroid of the estimated block, thus preventing grade smearing. | |||
oThe majority of the drill data is in close proximity to the historic open pit mines and data density becomes sparse as one moves |
|||
| away from them. The modeled ore body (Vein) solids were created using a max distance of 40m away from any data point, | |||
| thus preventing the overestimation of both geology and grade away form sample data. The depth of the interpreted veins was | |||
| clipped at 115m below surface. The bulk of the drill intercepts are at 40m depth below surface, but several deeper intercepts | |||
| exist. Due to the weighting assigned to the proximity of the samples to the centroid of the estimated block, samples at depth | |||
| with less sample support will receive low estimation weights and thus estimate lower grades in an attempt to prevent the | |||
| overstatement of grade in areas of lower sample support. | |||
| The result of this estimation does reflect the competent person’s view of the deposit. The domains are consistent with historic reports of | |||
| the mined veins and modeling has constrained strike extensions of geology so as not to extend far beyond data limits. The model grades | |||

| Geology • Deposit type, geological setting and style of mineralisation. |
EL 8538 covers a large portion of the Early Devonian Yeoval Batholith including felsic to mafic intrusives of the Yeoval Intrusive Complex. The Yeoval Complex is strongly fractionated and comprised of various intermediate intrusive lithologies – granite, quartz monzodiorite, quartz diorite, microgranodiorite, granodiorite, diorite and gabbro (Pogson et al 1998). The more fractioned intermediate phases are highly prospective for porphyry copper - molybdenum ± gold mineralisation. This Yeoval intrusive complex formed during a Late Silurian to Early Devonian melting and rifting event that split the Ordovician to Early Silurian Macquarie Arc. Its chemistry is shoshonitic, in common with the Ordovician volcanic rocks that host the Cadia and Northparkes porphyry copper-gold deposits, and a similar mantle source and mineral potential is inferred. |

| Emplacement of intrusives and extrusives in the Early Devonian which are related to the Boggy Plain Supersuite have given rise to intrusive | ||||

| the Goodrich Mine. The style of the mineral occurrences is indicative of a porphyry copper-gold setting. Minor occurrences of copper ± gold | ||||
| mineralisation is present within the microgranite and granite of the Yeoval Complex. Minor molybdenum is reported at the Martins Reef | ||||
| Prospect in the south-west of the licence area. Scattered copper-gold prospects also occur within the Silurian and Devonian sequences | ||||

The entire estimated Yeoval Project deposit has been classified as an Inferred Mineral Resources. In making this classification, the following factors have been considered. Data integrity oThe data is of sufficient quantity and quality for an Inferred Mineral Resource classification as stated by the CP for the estimation in 2009 and also as validated by our own inspections of the data in the model folder. oCollar survey methods and down hole surveys are sufficient for the spatial location of the drill holes Geological modelling and grade continuity: oThe continuity of grades >0.1 % Cu is generally good. |

| Sampling techniques | • Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. |
Sampling method description • Rock chip samples oThese samples are collected from outcrop, float, or other exposure. Samples are clear of organic matter. • Soil samples oThese samples are collected from the “C” soil horizon at depths up to 75cm deep or just above bedrock in shallow sub crop areas. The samples are sifted to minus 2mm and are free of organic matter. • Soil auger samples oThese samples are collected from the “C” soil horizon at depths of up to 3m below surface or upon refusal depth being reached (<3m). The samples are sifted to minus 2mm and are free of organic matter. • In order to optimise the samples ability to represent the mineralisation, the deepest possible sample is taken (<3m) in order to mitigate the misrepresentation caused by transported material. • These sampling methods are standard industry methods and are believed to provide acceptably representative samples for the type of mineralisation encountered. |

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Several companies have explored the district surrounding the Copper Hill workings. The variable cover over the northern portion of the tenement has likely resulted in past exploration programs in most cases, relying on geophysical (aeromagnetics and radiometrics) and geochemical surveys to generate targets for further work. Follow up of regional targets was generally undertaken on smaller grids with soil sampling and detailed rock chip sampling followed by geological mapping and geophysical. If exploration results warranted it, prospects were RC drilled and rarely diamond drilled, or diamond tailed. Some RAB drilling was completed to test beneath shallow alluvial and colluvial sequences. Early exploration was designed to test the Ordovician sequences for Copper Hill analogues including defining dacite porphyries and targeting magnetic depletion zones due to strong alteration in a NW trending dilational structural opening. The porphyries form narrow, typically less than 250 m in diameter, but vertically extensive pipes, greater than 900m. The Copper Hill porphyry occurs within a NW trending gravity low (dilation opening) indicating a felsic pluton at depth, and also strong magnetic low which is considered integral to their formation. Early exploration in the northern portion of EL8556 was designed to test the Ordovician sequences for Copper Hill analogues including defining dacite porphyries and targeting magnetic depletion zones due to strong alteration in a NW trending dilational structural opening. |

• Geology The northern portion of the tenure straddles the Molong Volcanic Belt of the Ordovician Macquarie Arc and comprises of the Ordovician rocks of the Fairbridge Volcanics and Oakdale Formation. The units strike north-south and dip and young to the west. The Fairbridge Volcanics represent Phase 2 magmatism of the Macquarie Arc. The southern portion of the tenement comprises the oldest sequence the Late Ordovician Oakdale Formation which occurs towards the west of the tenure. The sequence is interpreted as been deposited in a relatively deep basinal environment. |

||
| On August 5th 2014, TriAusMin underwent a corporate merger with Heron Resources Limited which resulted in Heron acquiring 100% of EL | |||
| 5583 and the 289 hectares of freehold land over Lewis Ponds. In 2017, Ardea Resources Ltd was “spun out” as a new company, and | |||
| gained ownership of EL 5583, with TriAusmin becoming a wholly owned subsidiary of Ardea. | |||
| In the 1850’s gold was discovered at Lewis Ponds and shallow underground mining took place at Spicers, Lady Belmore, Tom’s Zone and | |||
| on several mines in the Icely area during the period 1887 to 1921. In 1964, a number of major companies including Aquitaine, Amax, Shell | |||
| and Homestake explored the region looking for depth and strike extensions of the Lewis Ponds mineralisation but failed to intersect | |||
| significant mineralisation. These companies had drilled approximately 8,500 metres. Not commonly noted, but of great significance is the | |||
| fact that much of Lewis Ponds’ early development was in lieu of the high grades of silver in its ores. It appears that silver was the major | |||

| hosts a range of base metals in volcanic-hosted massive | |||
| sulphide deposits (VMS), porphyry copper-gold and gold | |||
| deposits, including Woodlawn (polymetallic), Cadia- | |||
| Ridgeway (Cu-Au), North Parkes (Cu-Au), Copper Hill (Cu- | |||
| Au), Tomingly (Au) and McPhillamy’s (Au). | |||
| The Molong Volcanic Belt is west of the EL 5583 and | |||
| comprises Ordovician to early Silurian basal units of mafic to | |||
| ultramafic volcanic and sedimentary rocks of the Kenilworth | |||
| and Cabonne Groups. These units are separated from the | |||
| Hill End Trough by the extensive Godolphin Fault Thrust | |||
| System. | |||
| The Mumbil Group unconformably overlies the Molong | |||
| Volcanic Belt and comprises shallow-water Later Silurian | |||
| sequence of felsic volcanics, volcanoclastics, siltstone and | |||
| limestone. Part of this Group is the Barnby Hills Formation | |||
| at Lewis Ponds and comprises (tuffaceous) siltstones | |||

| east and conformably overlying rocks of the Mumbil Group, | |||
| siltstone and minor sandstone units form part of the Silurian- | |||
| Early Devonian Hill End Trough sedimentary sequence | |||
| The Lewis Ponds deposit is located in a locally highly | |||
| structured zone within the western limb of a north-west | |||
| plunging syncline. The deposit consists of stratabound, | |||
| disseminated to massive sulphide lenses. | |||
| The deposit is hosted in Silurian felsic to intermediate | |||
| volcanic rocks as a thin, mostly fine-grained sedimentary | |||
| unit with occasional limestone lenses that has undergone | |||
| significant deformation and is now defined as a steeply east | |||
| dipping body with mineralisation that occurs over a strike | |||
| length of more than 2km. | |||
| The Southern mineralisation occurs within a limestone | |||
| breccia and Tom’s mine is hosted by siltstone and consists | |||
| of fine-grained tuffaceous sediments. The mineralised zones | |||
| unconformably overlie a sequence of strongly foliated and | |||
| hydrothermally altered quartz-plagioclase dacite. | |||
| Mineralisation occurs in two main styles: plunging shoots of | |||

| Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No new exploration results are reported in this release. Data aggregation methods used in the Mineral Resource Estimate are detailed in Section 3 Estimation and modelling techniques. |
| Relationship between mineralisation widths and intercept lengths • These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
The mineralised units are near vertical and drilling has almost exclusively been conducted from the east at perpendicular angles with the mineralised units. The drill angles vary, but is generally at 60 degrees down, resulting in mineralised intersections slightly longer than the true width. Interpretation of the mineralised units honour the true width. |
| Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
No new exploration results are reported in this release. The Mineral Resource Estimation has used all available project data. |

Inferred open pit resources are defined by wider spaced drilling and limited by a DTM surface defining the base of reasonable expectations of economic extraction, where sufficient drilling confidence exists that the continuity of geology and mineralisation can be extended. The Inferred portions of the Mineral Resource has an average kriging slope of regression of 0.4 to 0.5 and an average distance to informing composite data of 70 to 80m. Underground Mineral Resources are classified as Inferred as a result of the less continuous nature of the lodes, wider spaced data defining the lodes and the resulting fewer informing composite data.
