ACCEPT THE IMPROVED RAMELIUS OFFER

18 December 2018

Explaurum Limited ( Explaurum ) provides the following update to Explaurum Shareholders in relation to the improved offer by Ramelius Resources Limited ( Ramelius ) announced on 13 December 2018.

Improved Offer

Explaurum notes that Ramelius has increased the consideration of its original offer by 2 cents cash per Explaurum Share in addition to the existing consideration of 1 Ramelius Share or every 4 Explaurum Shares and extended the Offer Period until 25 January 2019 ( Improved Offer ).

Ramelius has confirmed that the Improved Offer is best and final and will not be increased.

Accordingly, under the Improved Offer, Explaurum Shareholders will receive:

  • one Ramelius Share for every four Explaurum Shares; and

  • 2 cents cash per Explaurum Share.

Ramelius has also agreed to advance to Explaurum an unsecured and interest free loan to meet its financial commitments.

Recommendation and intention of Explaurum's Directors

The Explaurum Directors have carefully considered the terms of the Improved Offer and have unanimously resolved to recommend that Explaurum Shareholders ACCEPT THE IMPROVED OFFER , in the absence of a superior proposal.

Each Explaurum Director who has a relevant interest in Explaurum Shares intends to ACCEPT THE IMPROVED OFFER , in the absence of a superior proposal for all of the Explaurum Shares in which they have a relevant interest.

For information on how to ACCEPT THE IMPROVED OFFER , please refer to section 5 of Ramelius' Fifth Supplementary Bidder's Statement and the replacement Acceptance Form, which have both be despatched to Explaurum Shareholders.

==> picture [376 x 37] intentionally omitted <==

Key reasons for the Explaurum Directors' recommendation

The Explaurum Board has recommended that Explaurum Shareholders accept the Improved Offer for the following key reasons:

1. The Improved Offer includes an increase to the Offer Consideration

The Improved Offer implies a value of Explaurum Shares of A$0.134 each, based on the closing price of Ramelius Shares and Explaurum Shares as at 12 December 2018[1] .

  • The implied value of the Improved Offer represents a premium of:

  • 57.6% to Explaurum's closing price of A$0.085 on 12 December 2018[2] ; and

  • 54.0% to Explaurum's 10 day VWAP of A$0.087 up to and including 12 December 2018[3] .

The Explaurum Directors also note that the Improved Offer includes a cash component, which will enable Explaurum Shareholders to immediately realise value for their Explaurum Shares.

2. The Improved Offer provides greater certainty

Ramelius advised that it intends to make the Improved Offer unconditional if the Alkane Strategic Investment is not approved by Explaurum Shareholders, or it otherwise does not proceed. Ramelius will provide the Offer Consideration to accepting Explaurum Shareholders within 14 days thereafter.

In light of the Improved Offer, it has become apparent to the Explaurum Board that the prospects of the Alkane Strategic Investment being approved by Explaurum Shareholders are low.

Accordingly, Explaurum and Alkane Resources Limited ( Alkane ) have agreed to terminate the Share Subscription Agreement dated 28 October 2018, so that the Improved Offer can be made unconditional.

Once the Improved Offer becomes unconditional, the uncertainty in relation to receiving the Offer Consideration that was inherent in Ramelius' original Offer will be removed.

1 Based on the closing price of Ramelius Shares of A$0.455 and a closing price of Explaurum Shares of A$0.085 on 12 December 2018 being the last day before the announcement of the Improved Offer.

2 Being the last closing price before the announcement of the Improved Offer.

3 Being the last closing price before the announcement of the Improved Offer.

==> picture [376 x 37] intentionally omitted <==

The Explaurum Director's also note that Ramelius have confirmed that the Improved Offer is best and final and will not be increased.

3. There is a risk that Explaurum Shareholders who do not accept the Improved Offer may become minority shareholders

The Explaurum Directors have had regard to the fact that Explaurum Shareholders who do not accept the Improved Offer may become minority shareholders in Explaurum.

Ramelius has advised that it holds a relevant interest in 26.73% of Explaurum Shares[4] .

Ramelius has previously indicated that if it becomes an Explaurum Shareholder, depending on the level of acceptances, it intends to (among other things):

  • Reconstitute Board – seek majority representation on the Explaurum Board;

  • Operational control – implement the results of its Strategic Review; and

  • Delist Explaurum – investigate the removal of Explaurum form the official list of ASX.

If any of these occur, the Explaurum Directors will not be in a position to guarantee the present strategic direction of the Company or give any assurance about the future ability of Explaurum to create long-term value for Explaurum Shareholders.

The Explaurum Directors also note there is a risk that the price of Explaurum Shares may fall to levels below the Improved Offer price if you do not accept the Improved Offer and Ramelius acquires a substantial shareholding in Explaurum.

4. Short term funding

The Ramelius loan facility will provide sufficient working capital funding to meet Explaurum’s forecast cash commitments until the end of January 2019, thereafter any additional funding is at Ramelius’ discretion. The loan is repayable on 30 June 2019 or such later date as the parties agree.

Supplementary disclosure by the Independent Expert

The Independent Expert, BDO Corporate Finance (QLD) Ltd, completed its report in relation to Ramelius' original Offer, which was despatched to Shareholders on Thursday 6 December 2018.

==> picture [376 x 37] intentionally omitted <==

The Independent Expert's Report did not take into account and consider the Improved Offer, the Initial Mace Resource Estimate or the Tampia Feasibility Study Update. Accordingly, Explaurum confirms that the Independent Expert is preparing supplementary disclosure which considers these additional items and provides an assessment of the Improved Offer. The Board’s recommendation and their personal voting intentions are not conditional upon the outcome of any supplementary disclosure from the Independent Expert.

Explaurum Board

As Ramelius now has a relevant interest in 26.73% of Explaurum Shares, a nominee of Ramelius will be invited to join the Explaurum Board.

Cancellation of Alkane Meeting

As the Alkane Strategic Investment is no longer proceeding and the Ramelius Offer will become unconditional, Explaurum intends to cancel to the General Meeting scheduled for Friday, 21 December 2018.

EXPLAURUM LIMITED

INITIAL MACE RESOURCE ESTIMATE

==> picture [76 x 76] intentionally omitted <==

07 December 2018

Explaurum Limited ( Explaurum or the Company ) is pleased to provide an update on the initial Mineral Resource estimate for the Mace supergene mineralisation based on recent RC and diamond drilling programs.

HIGHLIGHTS

  • The Mace deposit extends from the southwestern margin of the proposed Tampia open pit. It is 40-80m wide with an average thickness of 5m from approx. 8m below surface and is hosted within clay.

  • Coarse gold distribution and challenged drill sample quality has limited the ability of the initial Mineral Resource estimate to be classified at a higher level of resource confidence. The grade of the resource estimate is also considered to be conservative by the Competent Person.

  • The initial Mineral Resource estimate for the Mace deposit is 400kt at 1.4g/t Au for 20,000oz contained gold, which has been classified in the Inferred category in accordance with the JORC Code (2012):

Classification Tonnes
(‘000)
Grade
(g/t Au)
Cont. gold
(koz)
Inferred 400 1.4 20
Total 400 1.4 20
  • The Mineral Resource estimate is based on 310 RC drill holes (for 7,403m), on a 20m x 10m drill spacing, plus 25 diamond drill holes (for 427m). It covers only 700m of the strike extent of the Mace deposit.

  • The distribution and continuity of mineralisation between drill lines is excellent. Given the mineralisation is at shallow depth and hosted by unconsolidated sediments, any mined ounces at Mace possess the clear potential to deliver high metallurgical recoveries and very low operating costs.

  • Extension drilling to the west recently increased the strike extent of the Mace deposit by a further approximate 400m to over 1.1km. Further extension drilling is planned to commence in early 2019.

  • Mine planning for the Mace deposit, together with significant capital and operating cost optimisations across the broader Tampia Gold Project, are currently being undertaken as part of the Bankable Feasibility Study targeted for completion this month.

Commenting on the progress at Mace, Explaurum Managing Director, John Lawton, said:

“At a headline level, the initial Mace Mineral Resource estimate has returned a somewhat frustrating result. However, the finer detail behind it presents a different story. The infill RC drilling program was undertaken on a close-spaced 20m x 10m drill pattern, with many high-grade intercepts being returned. However challenging sample quality, as a result of the gold mineralisation being coarse, or nuggety, and being hosted by unconsolidated clay, has had the effect of significantly negatively biasing the final grade estimate for the resource.

“This dynamic is illustrated simply by comparing the RC drilling results with the corresponding diamond drilling results. The average RC intercept grade of 4.1g/t Au is less than half of the average diamond drill intercept grade of 9.4g/t Au. The Competent Person has clearly established that, on a statistical basis, all RC intercept

grades above 0.6g/t Au are negatively biased, thereby significantly downgrading estimation of the actual gold grade. This relatively low statistical level of confidence in the grade estimate is the reason why the Mace Resource cannot be classified in anything other than the Inferred category.

“Notwithstanding these dynamics, the strong grade, shallow depth and sediment hosted nature of the Mace supergene mineralisation highlight that this material has excellent potential to deliver high recovery and low cost ounces early in the proposed Tampia mine plan – a dynamic that we are rapidly evaluating.

“We have now confirmed the presence of a sizable body of shallow, enriched gold mineralisation at Mace. The strike extent of this mineralisation exceeds 1.1 kilometres – and remains open to the west. Subject to approval of the Alkane strategic investment, we plan to aggressively accelerate extensional drilling at Mace in early 2019.”

Mace infill RC drilling

The Mace mineralisation extends from the southwestern margin of the proposed Tampia open pit for more than 1,100m. It is up to 80m wide with an average thickness of 5m from approx. 8m below surface. The eastern most 700m strike length of gold mineralisation on the main mining lease has been infilled to a 20m by 10m drill spacing in order to generate an initial Mineral Resource estimate (Figure 1 and Figure 2).

==> picture [420 x 336] intentionally omitted <==

Figure 1. Tampia Project location map.

A total of 223 infill RC holes were completed for a total of 4,433 metres (Table 1), in addition to previously reported drill programs (as reported in the EXU announcements of 7 September 2018, 3 July 2018 and 12 March 2018).

  • 6m at 1.12 g/t Au from 3m in MPRC297;

  • 6m at 19.00 g/t Au from 4m in MPRC304, including 2m at 55.55 g/t Au from 8m;

  • 5m at 2.09 g/t Au from 7m in MPRC307;

  • 5m at 4.47 g/t Au from 9m in MPRC314;

  • 2m at 4.95 g/t Au from 15m in MPRC323;

  • 5m at 9.76 g/t Au from 10m in MPRC338, including 2m at 21.75 g/t Au from 12m and

  • 6m at 2.11 g/t Au from 14m in MPRC343 (Tables 1 and 2, and Figure 3).

The infill drilling continued to intersect high grade gold mineralisation, with up to 147 g/t Au intersected in MPRC274 in this phase of drilling (Table 2). This was similar to the high-grade gold mineralisation intersected previously in MPRC025 of up to 144 g/t Au at similar depths (Figure 3; Table 2).

The 137 g/t Au sample from 10-11m in MPRC122 was panned to check the assay result and check for the presence of visible gold. The host to the gold mineralisation is a yellow, limonitic clay in the saprolite zone. Significant amounts of coarse free gold were panned (Figure 3). The gold appears predominantly coarse with very little fine gold in the tail and appears crystalline and 0.5-1mm in size. The tail also includes a significant amount of magnetite. The panning confirms the assay grade and the presence of coarse free gold in the resource.

Only 700m of the 1,100m mineralised zones has had infill drilling completed due to farming activities and the initial Mace Mineral Resource estimate is confined to this area. The distribution and geological continuity along and between sections of the supergene gold mineralisation continues to be good, although grade continuity appears to be variable as would be expected with coarse gold distribution.

Mace diamond drilling

The eastern most 700m strike length of gold mineralisation on the main mining lease has been tested by diamond drilling, which has provided important geological data on the controls of gold mineralisation and enabled metallurgical test work to be completed (Figure 4).

There were 25 diamond holes completed for a total of 427 metres (Table 3). There were 13 holes drilled to verify the RC drill assay results, 5 holes drilled to provide sample for metallurgy test work, 4 holes drilled for geotechnical studies and 3 holes drilled to collected geological data.

Better intersections included (Table 4):

  • 4m at 6.20 g/t Au from 11m in MPDD001;

  • 3m at 24.99 g/t Au from 12m in MPDD002, including 1m at 70.90 g/t Au from 13m;

  • 10m at 4.47 g/t Au from 0m in MPDD014, including 1m at 26.80 g/t Au from 4m.

All the twin diamond holes were mineralised, confirming that the Mace supergene gold resource area contains high grade gold mineralisation up to 173 g/t Au, like the high-grade gold mineralisation intersected previously in MPRC025 with 144 g/t Au and MPRC122 with 137 g/t Au, and at similar depths (Figure 4; Table 4).

The diamond drilling intersected gold mineralisation in a similar stratigraphic location as the RC drilling (compare Table 2 and Table 4). The diamond core intersections are on average narrower and higher grade than the RC intersections with an average diamond core intersection width of 5m compared to an average RC intersection width of 9m and an average diamond core grade of 7.92 g/t Au compared to an average RC grade of 4.37 g/t Au (Table 5).

The distribution and geological continuity along and between sections of the supergene gold mineralisation continues to be good, although grade continuity appears to be variable with a strong nugget effect. This is evident in the two pairs of check diamond holes MPDD011 and MPDD014, which have similar widths of 9m and 10m respectively but significantly different gold grade of 0.79 g/t Au and 4.47 g/t Au respectively. These results were used for geostatistical analysis for resource estimation.

Geology and mineralisation

Regional geology

The Mace deposit is part of the larger Tampia Gold Project, which is located in the Southern Cross province near the boundary between the Western Gneiss terrane and the Southern Cross Greenstone Belt. The Western Gneiss terrane can be divided into three smaller terranes comprising different metamorphic belts, each separated by major thrust faults. The Lake Grace terrane, encompassing the Tampia Hill area, is the easternmost of these. This terrane contains many greenstone belt remnants that have all been metamorphosed to granulite facies. The terrane is dominated by banded felsic and granulite gneiss that have been intruded by undeformed seriate and porphyritic granite. Belts of mafic gneiss occur inter-fingered with the felsic gneiss as well as minor metamorphosed banded iron formation (BIF) and metasediments. Zircon geochronology from hypersthene-bearing granites that are interpreted to have intruded during granulitefacies metamorphism within the Lake Grace terrane, have a U-Pb age of 2,627 ± 12 Ma, and granitoid gneisses around Dumbleyung have Rb-Sr whole rock ages of 2,611 ± 162 Ma. The youngest granitoids also come from this region, with an average age of 2,587 ± 25 Ma. These younger coarse-grained granodiorites postdate granulite-facies metamorphism in the Lake Grace terrane and intrude the migmatites and charnockitic granites.

Local Geological Setting and Mineralisation

The stratigraphy at Mace has been defined from detailed logging of 12 PQ diamond core holes and 223 RC holes drilled for resource estimation and is described below.

7

Quaternary Sediment (QA)

The top of the sequence is a ferruginous clay rich soil, which contains fragments of lateritic cap, pisolites and weathered mafic gneiss at the base of the sediment, thus it is interpreted to have been recently transported. This unit is called Quaternary Alluvial Sediment (‘QA’ in Figure 6) and the base of the unit is defined by Erosion Surface 1.

Tertiary Sediment (PC)

Below Unconformity 1 lies a second sedimentary unit, Tertiary Sediment (‘PC’ in Figure 6), that follows the Quaternary channel. It comprises grey clay and quartz grains from 1/16 mm to 2 mm. The unit grades from little quartz in the top of the unit, with sand increasing in proportion and grainsize, from 1/16 mm to 2mm, with depth. This unit varies in thickness from 1 m to 20 m with the base of the unit typically contains large quartz cobbles (e.g. Figure 6). These quartz cobbles vary in size from 1 to 10 cm and they are well-rounded, suggesting they have travelled significant distances. The cobbles also include lithologies that are not present at Tampia. This unit has been lateritised and is overprinted by the mottled zones and upper saprolitic zone.

The Tertiary Sediment is not continuous and thins to the north and east where Quaternary Alluvial Sediment directly overlies the Archean basement. The Tertiary Sediment is thickest over the preferentially-weathered Archean felsic gneiss. The base of the unit is defined by Erosion Surface 2.

Mottled Zone (MZ)

Underlying the Tertiary Sediment is a residual Archean regolith profile, consisting of residual lateritised saprolitic clays of the Archean felsic and mafic gneiss basement, which hosts the gold at Tampia. At the top of the regolith profile is a mottled zone (‘MZ’ in Figure 6) comprising of red and white mottled and clays.

Upper Saprolite (US)

A leached upper saprolite (‘US’ in Figure 6) occurs below the MZ; it is a grey clay with quartz sand (grey quartzwacke). This US is distinguished from the underlying lower saprolite zone by the generally higher degree of oxidation and colour. The oxidation front and change from lower to upper saprolite suggests a change in redox state. The US is typically more extensive over the felsic lithologies and more mottled over the mafic lithologies.

Lower Saprolite (RLS)

Underlying the US is a lower saprolite zone (‘RLS’ in Figure 6), in which the original minerals in the rock have been strongly weathered and altered. The RLS is typically greenish in colour and friable. The lower saprolite has an ‘oxidation front’ between oxidised minerals above, and reduced minerals below.

Residual Saprock (RSR)

A well-established lower residual saprock (‘RSR’ in Figure 6) has developed above the fresh basement rocks. In this zone, weathering is restricted along joints, foliations, faults and other failures within the fresh rock. Geometry and geochemical characteristics of the Tampia mineralisation are mostly preserved in this unit.

Gold Mineralisation

The orientation of the Mace deposit geology and the gold mineralisation are controlled by the Tertiary Sediment, which generally follows the modern drainage system. The Tertiary Sediment unit is thickest and best developed in the deepest weathered areas, which is interpreted to be an infilled paleochannel that cuts through the Felsic Gneiss. The Tertiary Sediment occurs as a narrow linear body 40m wide in the southeast over the mafic gneiss that hosts the gold mineralisation at Tampia. The Tertiary sediment is wider, averaging 100m, over the felsic gneiss to the south west. The Tertiary Sediment then narrows to about 40m over the next mafic gneiss to the west of Tampia. The Tertiary Sediment then bifurcates over the next felsic gneiss unit where it can reach widths of up to 250m wide. The Quaternary Alluvial Sediment is a pervasive blanket cover of approximately 3m thick covering the entire local area.

Figure 6. Schematic evolution of the mace geology since exhumation of the Archean basement.

Gold mineralisation present in the unweathered Archean rocks and residual saprock below the alluvial channel at Mace (‘Dm1’ in Figures 6, 7 & 8; within AB and RSR) are accounted for in the Tampia hard-rock gold Mineral Resource estimate.

The majority of the gold mineralisation at Mace is hosted in the regolith (RLS, US, and MZ). Where laterisation is spatially related to the Tertiary sediments in the paleo-channel the mineralisation has been labelled as ‘Dm2’ (Figures 6, 7 & 8). Some minor mineralisation in the Quaternary sediments (QA) is also grouped within Dm2 because the mineralisation in the Quaternary sediments is patchy, often contiguous with the saprolitic Dm2 domains, and do not have significantly different statistical characteristics. Where the laterisation has affected the Archean bedrock, with no clear relationship to the paleo-channel, the mineralisation has been labelled as ‘Dm3’ (Figures 6, 7 & 8).

Dm2 mineralisation is best developed in the deeper parts of the Tertiary paleo-channel. It is spatially associated with the paleo-channel, which suggests a component of lateral transport of the gold through supergene redistribution. The gold re-deposition is related to a change in clay colour from light grey to brown-yellow, which represents the redox front. This supergene re-deposition of gold transcends laterally along the RLS–US and US–MZ boundaries, and importantly, across the paleo-channel boundaries into the felsic gneiss regolith. Some of the coarse gold grains panned from the drill cuttings have crystal faces, further supporting this model of dissolution and re-deposition.

Drilling Techniques

Due to time constraints, the gold mineralisation at Mace was drilled with the same drill equipment that was used for the drill-out of the Tampia deposit. A total of 344 RC holes were drilled to an average depth of 15.6m on a 20m by 10m drill pattern during the 2018 Mace resource definition drilling program. Low drill recoveries were noted in the earlier drill holes at Mace, due to clays getting stuck in the RC equipment. Diamond holes were therefore drilled in order to twin selected RC holes to compare assay results for quality control studies. Fourteen of the RC holes were twinned by diamond holes.

Reverse circulation drilling equipment with face sampling hammers were used to collect samples. The drilling was conducted by an Atlas Copco E220RC Explorac. No booster was used due to drilling shallow holes. All new drill bits were supplied as 146 mm or 143 mm, had a shroud size of 145 mm or 142 mm, and were sized to suit as they wore. All rods were Harlson 4 ½ inch RRE Rods, which are 6 m long, with a 4 m starting rod used. All sample hoses were 76 mm inside diameter.

To try to mitigate the issues with poor sample recoveries, stringent standard operating procedures (SOPs) for the drilling process were used. The Competent Person has reviewed these and, even though the drilling technique was sub-optimal for the deposit, considers the SOPs to provide reasonable assurance of the drilling quality, and fit for the purpose of establishing an Inferred resource classification.

Specifically, water issues were controlled by investing the time to set proper collars, and by having appropriate equipment on site, including blow-down valves and sufficient air pressure. The first 39 holes (MPRC001 – MPRC039) had PVC collars to fresh rock, the following 82 holes (MPRC040 – MPRC121) had PVC to a sufficient depth to maintain air pressure for reasonable sample return. Holes MPRC122 – MPRC344 were not collared due to their shallow depth. In rare instances where wet drilling could not be avoided, holes were terminated. Any issues with wet drilling (leading to sample loss) were noted for each sample.

Loss of fine material through the cyclone vortex finder was managed by infusion of mist spray.

Metre delimitation was carefully controlled by a process of total sample bag weighing and monitored on a control sheet after standardising for bit size and density of the specific lithology from the logging. Delimitation plots were generated on a daily basis and used as a tool for continuous improvement of the drillers’ procedures.

10

Sampling and sub-sampling techniques

Samples collected by the drill hammer were delivered to a Metzke Splitter for sub-splitting. The splitters were specifically purchased for the 2017 Tampia hard-rock resource definition program as they provided a superior split over the more industry-standard cone splitter. However, at Mace, these devices had little positive effect, as sticking clays caused sample splitting issues.

Recoveries were generally low, with an average of 65% in samples over 0.2 g/t Au. To evaluate the sample quality and determine its fitness for the purpose of resource estimation, results of 14 diamond drilling control samples were investigated. The diamond core was of PQ size and collared as close to existing RC holes as possible. Holes were drilled along the long axis of the deposit, thereby providing a representative sub-set of data for comparison. Samples were submitted to the laboratory as whole-metre intervals, where they were crushed, pulverised and leached. The results of samples within a 5m buffer of RC samples, with diamond core recoveries of more than 80%, and within the low-grade mineralisation domain were compared using a quantile-quantile plot (Figure 9). This resulted in 55 sample pairs, sufficient for statistical comparison.

==> picture [277 x 239] intentionally omitted <==

Figure 9. QQ plot of diamond control drilling and RC resource drilling

The results show that the RC results are biased low above approximately 0.6 g/t Au, with the diamond control samples being higher on average than the RC drilling. The means of the two data sets (with diamond data set capped at 63 g/t, the maximum grade in RC population) are markedly different (9.4 g/t for diamond and 4.1 g/t for RC), which is due to the several high-grade ‘outliers’ in the diamond control data set that are not present in the RC dataset.

It is clear that the RC drilling does not efficiently recover coarse gold, likely due to a combination of drilling type, splitting process and analytical process, whereas in the diamond core drilling and sampling, apart from perhaps minor plucking effects, all gold in the primary sample is reported in the final assay. Sonic drilling, followed by whole-sample leaching would be the best drilling and sampling method for this type of mineralisation and host rock.

Chutes on the splitters were adjusted to deliver a maximum-size sample split to the laboratory, in the order of 3 – 4 kg. This weight was assumed to be fit-for-purpose, rather than determined by a nomogram, as there was little to no pre-existing sample data for Mace available. The coarse nature of the gold does not make this a suitable split size, which is reflected by the diamond control sample results. The performance of splitting was monitored on a per-sample basis by collecting a duplicate split sample for each metre. The difference in sample weight acted as a proxy for sample split consistency, which was monitored in a spread sheet in real-time. Reasonable precision was demonstrated form the analysis of duplicate primary sample splits (Figure 10). The Competent Person audited this performance throughout the campaign and, apart from minor issues, deems

11

the sample splits of reasonable quality and, following comparison with diamond drilling control samples, marginally fit for the purpose of resource estimation.

The sample splits were submitted for the same sample preparation process as the samples for the Tampia hard-rock deposit. Samples were weighed wet (on site) and wet (at the laboratory), and then split in a Rocklabs Boyd RSD Combo, which allowed a percentage linear split to be specified for each sample. The split weights were optimised for pulverising in Essa LM-2s and their percentage passing size monitored consistently. Samples were then milled in the LM-2s before a manual split of around 200 g was put in brown paper bags. The final 50 g charge weight was weighed from this. Duplicate samples were inserted at each of the splitting stages, to monitor precision. Duplicates were collected at >10% from mineralised zones only. Samples that were duplicated in the field were also flagged for duplication at subsequent splitting stages at the laboratory. The Competent Person notes that such a splitting process is not necessarily optimal for this style of mineralisation but considered acceptable for the purpose of mineral resource estimation and appropriate classification.

Duplicate results for primary splits, secondary (crush) splits and pulp splits were monitored, and no significant bias was noted in the splitting processes.

In the Competent Person's opinion, the sampling and sub-sampling were not always accurate (leading to lower-grade bias), and often imprecise. However, based primarily on the results of the diamond control drilling, the methods are considered marginally fit for the purpose of resource estimation. The likely under-reporting of Au content provides a potentially significant upside to the project but can only be proved with better-quality drilling or mining.

Sample Analysis Method

All samples were analysed at ALS Laboratories in Perth, Australia. All samples used in the Mineral Resource estimation were assayed via fire assay with atomic absorption spectroscopy (AAS) finish. Charge weights of 50 g were used, with careful management of the flux ratios and fusion process. Standard fluxes were used on normal samples, and the fluxes adjusted before potting based on the oxidation, base metal and sulphur levels (based on portable X-ray fluorescence (pXRF) values). Fusion and cupellation happened under controlled conditions at 1100 and 900°C respectively. Prills were digested in aqua regia and then flamed in AAS. Any issues noted by the lab were documented.

The Competent Person has audited the laboratory prior to the 2018 drilling campaign and has carefully reviewed each step of the flux-mixing, fusion, deslagging, cupellation, digestion and AAS process. At the time of auditing, all steps were carried out in accordance with ALS's standard operating procedures.

A thorough quality control program was applied for sample analysis. In addition to ALS's own internal use of CRM material, a range of OREAS standards were used that were selected to cover the grade range, including CRMs close to the cut-off value. Daily monitoring identified several minor instances of errors at the laboratory (Figure 11), which were all immediately discussed with the laboratory management and resolved. After analysis of all results via appropriate monitoring systems, in the Competent Person’s opinion, the laboratory has delivered consistent results throughout the campaign.

Figure 11. Consistency monitoring of accuracy using CRM OREAS 254.

Following the monitoring of consistency at the laboratory and the establishment of consistent results, all CRM laboratory results were checked for bias against the certified values. This was done for both Explaurum and ALS CRMs (total 7 different CRMs). Although some CRMs performed better than others, no statistically significant bias was detected.

The laboratory results are considered accurate across the entire campaign by the Competent Person.

Bulk Density

Bulk densities were measured using the core-submersion method for selected samples from the diamond drilling. Samples were not coated with wax prior to submersion and were not allowed to dry, because most of the samples were of very competent clay, which did not break up in water. Bulk wet densities were calculated and later converted to bulk dry densities after drying at the laboratory. The process was carefully qualitycontrolled and several process errors remedied throughout. Density values were compared with theoretical values by calculating the volume of the core and recording the weight, showing acceptable differences.

The Competent Person notes that determination of bulk dry densities using the water-submersion technique in regolith or conglomeritic material is difficult and therefore often discouraged. However, review of the processes and the results show a process of due care and results that align with several calliper-method cross checks. The density data therefore are fit for the purpose of resource estimation.

13

Estimation Methodology

The Mineral Resource was estimated using ordinary kriging (OK). This method was selected because, after subdomaining into low-grade (LG) and high-grade (HG) domains, followed by minor grade capping, the data showed an acceptable coefficient of variation within each of the domains (CV < 1.6).

Because of the observed relatively abrupt (‘hard’) grade boundaries, the estimation was carried out within the LG and HG domains, aiming to constrain the interpolation to only relevant samples that are broadly characterised by the same geological features. Significant effort was expended to find geological signatures that would identify and isolate different mineralised zones, or that would, for instance, define drivers for highvs low-grade zones.

The gold mineralisation at Mace mostly occurs as supergene. It has been separated into two domains, based on general geometry and depositional processes, with the Dm2 domain being spatially associated with the paleo-channel and being very continuous along the long axis of the deposit, and the Dm3 domain being associated with several flat lenses of typical supergene mineralisation hosted in the lower saprolite. The mineralisation appears to envelope the boundaries between regolith units (e.g. redox front, interface between MZ and US), rather than being contained within specific geological units, and therefore domains were not defined by geological boundaries but by grade boundaries.

Sample data points were extracted within the domains for the drilling of the recent 2018 drilling campaign and RC exploration drilling in the Mace area during 2016 and 2017. Diamond drilling was not included in the estimation as many of the holes were either twin drill holes to confirm RC results or were not sampled as they were drilled for other purposes (geotechnical and metallurgical). No compositing was required as all samples were 1 m. RC grades were not adjusted following the outcome of the diamond twin drilling.

Variograms were modelled for each of the domains. This showed a nugget of 55% for low-grade, and 70% for the high-grade domains, and long ranges of 35m for low-grade, and 15m for high-grade domains. These are relatively high nugget values and are likely to include a component of sampling errors.

The domains were then estimated using ordinary kriging into panels with 10 x 5 x 2 m dimensions. The block size was determined through a process of kriging neighbourhood analysis, which showed a significant improvement when choosing a 2m over a 1 m vertical block height. Sub-celling was applied at SMU scale of 5 x 5 x 1m. Three passes were applied with increasing search ellipses and decreasing minimum number of samples, with first-phase search neighbourhood criteria set to minimum 12 and maximum 35 samples and a 17.5 m search radius, and second-phase criteria set to minimum 8 and maximum 35 samples and a 35m search radius, filling most of the blocks.

The OK estimate was compared and checked with a polygonal (nearest neighbour) estimate and showed a reasonable correlation (lower grade, more tonnes), given the volume-variance effect at a 0 g/t Au cut-off.

Resource Classification

The Mineral Resource estimate has been classified in the Inferred category (Table 6). There is no material classified as Indicated or Measured.

Classification Tonnes

Grade (g/t Au) Cont. gold (koz)

Notes:

1. The Mineral Resource is classified in accordance with JORC, 2012 edition

14

2. The effective date of the mineral resource estimate is 3 December 2018.

3. The Mineral Resource is contained within E70/2132, M70/815 and M70/816

4. Estimates are rounded to reflect the level of confidence in these resources at the present time. All resources have been rounded to the nearest 100,000 tonnes

5. The mineral resource is reported at 0.1 g/t Au cut-off grade

The Mineral Resource estimate has been classified in accordance with the JORC Code (2012). In classifying the Mineral Resource estimate, the Competent Person has considered the bias in the RC sampling on which the estimation was based. However, there is good comfort in the high Kriging efficiencies (~0.38), as a direct result of the close-spaced drilling and strict pattern, and despite the low co-variance demonstrated in the variograms. Any bias introduced by the poor sampling has therefore resulted in a conservative estimate and should be regarded as an upside to the project.

Portions of the deposit that do not have reasonable prospects for eventual economic extraction are not included in the Mineral Resource estimate.

Metallurgy

At Mace, metallurgical tests have been carried out on composited samples taken along the Mace paleo channel in the Tertiary sediments and adjacent weathered bedrock in the northwest part of the deposit.

Preliminary test work has shown that gravity and cyanidation are effective for the gold extraction as rapid and near complete dissolution of gold will result in greater than 96% gold recovery at moderate cyanide and low lime consumptions. Concentrations of arsenic and other deleterious elements (copper, antimony, tellurium, carbon and mercury) are low.

More test work is underway to investigate further metallurgical properties of the mineralisation and to cover the entire deposit. This will map the metallurgical zones of the deposit in more detail for mine planning purposes.

In the Competent Person’s view, the metallurgical test work is sufficient to show the potential for economic extraction of the Mineral Resource.

Cut-off Grades & Mining Methods

A cut-off grade of 0.1g/t Au on the resource blocks at SMU scale was determined as an appropriate cut-off grade. This value was adopted from the optimisation work carried out on the weathered material at the main Tampia deposit, which shows similar characteristics, and which took into consideration all available geotechnical, metallurgical, hydrogeological parameters. Various gold price scenarios were evaluated, with the selected 0.1 g/t Au cut-off reflecting a gold price of A$1675/oz.

Next steps

Additional extensional drilling

Extension and infill drilling of the +400m of the Mace mineralisation not currently in resource will be drilled after harvesting is completed in December. This has been planned along with extension and exploration drilling for additional supergene gold resources up to 1,700m to the west of the current Mace resource area targeting the creek and associated gold soil anomalies (Figure 12). This planned drilling consists of 633 RC drill holes for a total of 12,660m.

Section 1 Sampling Techniques and Data

Criteria JORC Code Explanation Commentary
Sampling
techniques
Nature and quality of sampling (e.g. 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.
One metre RC samples were collected via a
reverse circulation drill rig. These samples were
split using a Metzke rotary cone splitter system
to produce a 5kg representative sample. The
quality of the sample is actively measured using
various quality control techniques. The quality of
the sampling is deemed to be fit-for-purpose to
define a JORC Compliant Resource based on the
quality control metrics being used. Every effort is
made to ensure all samples are drilled dry and
when this is not possible samples are logged as
wet. Where samples are wet the pXRF sample is
left to dry before analysing.
Triple-tube diamond core samples were collected
via diamond drill rig, PQ core collected from
surface. The recovery of core was measured and
recorded by the driller and checked and
corroborated by the logging geologist. This
allowed for detailed logging of the lithologies
intersected and continuous sampling. Full core
samples were taken from the core to replicate
the RC samples wherepossible.
Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
Various quality control metrics are being actively
monitored to ensure the quality of RC samples
collected. Such measures include:

The collection of large 5kg sub-
samples from the splitter system.

The measuring and monitoring of total
RC sample to measure total recovery
and consistency of recovery and
therefore
monitor
the
metre
delineation of the rig (after correcting
for density based on lithology averages
and volume differences based on bit
size)

The collection of both primary and
duplicate
sub-samples
and
the
weighing of these samples to ensure
the consistency of the splitter system.

The collection of duplicates to test the
closed spaced variability of the deposit
and indicate adequacy of sample size.

The use of blanks to ensure the correct
calibration of laboratory equipment
and identify contamination at the
laboratory.

The
use
of
certified
reference
materials to test both accuracy and
precision of laboratory analyses.
Various quality control metrics were used to
ensure the quality of diamond drilled samples
collected, with recovery measured and recorded
by the drillers on the rig and corroborated by the
geologist when metre marked. Sampling was
constrained by lithological boundaries, with a
maximum sample size of 1m and a minimum
sample size of 20cm.
Aspects of the determination of mineralisation that are
Material to the Public Report. In cases where ‘industry
standard’ work has been done this would be relatively
simple (e.g. ‘reverse circulation drilling was used to obtain
1 m samplesfrom which 3 kg waspulverised toproduce a
5kg RC samples have been dried before fine
crushing, splitting using a Boyd rotary splitter to
produce an 800g sub-sample, which is pulverised
to produce a 50g sample for fire assay and

35

Criteria JORC Code Explanation Commentary
30g charge for fire assay’). In other cases, more
explanation may be required, such as where there is
coarse gold that has inherent sampling problems.
Unusual commodities or mineralisation types (e.g.
submarine nodules) may warrant disclosure of detailed
information.
multielement analysis via ICP-MS for Cu, Ni, Co,
As and S.
pXRF analysis was carried out on every RC metre
by taking a small 50g sample from the bulk RC
sample and analysing using a pXRF Vanta
Analyser with all three beams enabled with each
beam set to 10 seconds each.
Diamond core drilling was conducted collecting
PQ sized core samples. The diamond core was
sampled in full and samples size varied from
20cm to 1 metre dependant on mineralisation
and lithology. These samples were jaw crushed to
-2mm, a quarter (~300g) was riffle split and
pulverized and 50g aliquots were taken from this
sample for gold fire assay and full multi element
analysis via ICP-MS.
pXRF analysis on diamond core was conducted to
provide indicative lithogeochemical data by
taking 1-2 analyses per small lithological interval
or 3 analyses per metre for lithologies over a
metre. These analyses were taken using a Delta
Premium XRF Analyser with all beams enabled for
20 seconds each.
Drilling
techniques
Drill type (e.g. core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic, etc.) and
details (e.g. core diameter, triple or standard tube, depth
of diamond tails, face-sampling bit or other type, whether
core is oriented and if so, by what method, etc.).
Reverse circulation drilling equipment with face
sampling hammers were used to collect samples.
Metzke gravity fed fixed cone splitters were used
to take representative sub-samples of complete
metres. Drill bit diameter is recorded as part of
the logging to ensure correct volumes are used
for recovery estimations from total sample
weights.
A Boart Longyear KWL 1600 truck mounted
diamond drill rig was used to recover HQ sized
core. 3m rods were used and triple tube methods
were used to ensure sample recovery, especially
through clayzones.
Drill sample
recovery
Method of recording and assessing core and chip sample
recoveries and results assessed.
All sample recovery information was digitally
recorded on the rig using locked auto-validating
excel spreadsheets. Samples were weighed using
digital scales and recoveries were estimated
based on average density of logged lithology, bit
diameter (indicating volume of sample) and total
sample weight. The recovery was constantly
monitored using live-updating graphs.
The drilling crew measured each run and
recorded the amount of core recovered. This was
double checked by the geologist when the core
was meter marked. Due to the competent nature
of the mafic gneiss in Tampia Hill there was
minimal core loss, only occasionally recorded in
the shallow clay zone. Recovery was recorded as
apercentageper metre.
Measures taken to maximise sample recovery and ensure
representative nature of the samples.
An auxiliary booster is used to maximise air
pressure to improve RC sample recovery, which
allows most holes to be drilled dry. Where
samples were drilled wet, they have been logged
as such. Furthermore, constant monitoring of
recoveries via measurement and evaluation of
total sample weights on the rig enable recoveries
to be maximised.
Triple tubing was used to assume maximum
diamond core sample recovery.

36

Criteria JORC Code Explanation Commentary
Whether a relationship exists between sample recovery
and grade and whether sample bias may have occurred
due to preferential loss/gain of fine/coarse material.
No relationship between RC sample recovery and
grade has been observed.
Due to the high level of diamond core recovery,
an assessment of the relationship between
recoveryandgrade was not required.
Logging Whether core and chip samples have been geologically
and geotechnically logged to a level of detail to support
appropriate Mineral Resource estimation, mining studies
and metallurgical studies.
All RC chip samples have been geologically logged
to 1m resolution on the rig recording information
on rock type, mineralogy, mineralisation, fabrics,
textures and alteration. This logging is integrated
with geological logging from downhole optical
data, which can log to at least 10cm resolution
and records structural information for contacts,
foliation, banding and veining in the form of dip
and dip direction measurements. Magnetic
susceptibility and density measurements are also
used to assist this logging.
All core was logged by a geologist on a centimetre
resolution. Areas of proposed mineralization
were given extra attention. Features of interest
that were logged include; lithology, alteration,
structure and chemical composition (acquired
through pXRF analysis). Downhole Optical
Televiewer,
Acoustic
Televiewer
and
petrophysical
logging,
including
magnetic
susceptibility, gyro and density measurements,
were also conducted and paired with geological
and geotechnical logging. This logging provides
information on structure, contacts, foliation,
banding, veining etc. in the form of dip and dip
direction measurements on a 10cm resolution.
Whether logging is qualitative or quantitative in nature.
Core (or costean, channel, etc.) photography
The logging for the RC drilling was qualitative for
the geological data collection and quantitative
for structural, geotechnical and geochemical
data. A hand held XRF was used to collect
continuous geochemical data and Televiewer
optical and audio data collection allows the
measurement of structural and geotechnical
data.

2mm and split using a Boyd rotary splitter to
produce an 800g sub-sample which was
pulverised. From this 800g pulverised sample a
50g aliquot was taken for fire assay and finished
with ICP-OES. A multi-element assay was
collected via 50galiquot and an ICP-MS finish.

If non-core, whether riffled, tube sampled, rotary split,
etc. and whether sampled wet or dry.
Samples were split using a Metzke rotary cone
splitter system. Holes were kept dry wherever
possible via use of an auxiliarybooster.
For all sample types, the nature, quality and
appropriateness of the sample preparation technique.
The RC sub-sample taken for assay was split using
a rotary cone splitter system. A 5kg sample was
collected to minimise bias. The samples were
dried and fine crushed before being split with a
Boyd Rotary splitter to produce a 20% (800g)
subsample, which was pulverised, from which a
50g aliquot was taken for fire assay and multi-
element analysis via ICP-MS. The quality of these
sample has been measured via the quality control
methods
already
described.
The
sample
preparation method is deemed appropriate given
the mineralisation style.
pXRF samples were taken from the bulk reject
sample and given their purpose this sample
method is deemed appropriate. The samples
undergo no sample preparation and as such
indicative only.
The core samples collected are considered fit-for-
purpose as they are intended to provide
geological,
structural
and
mineralisation
information in a new area of interest.
Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.
RC duplicates are taken at all sub-sampling stages
from the same metre. A duplicate is taken from
the splitter system, crush duplicates are taken
from the Boyd Rotary splitter following fine
crushing and pulp duplicates are taken from the
pulverised sample before fire assay. The results
of these duplicate samples are assessed as results
are returned to identify problems as they may
arise to allow for their resolution as soon as
possible.
The core samples are considered representative
and fit for purpose with each split considered for
accuracy and precision. Each split is conducted
after a crushing stage to reduce particle size and
improve homogeneity. A balance between
practicality and price has been found and is
deemed optimal.
Measures taken to ensure that the sampling is
representative of the in-situ material collected, including
for instance results for field duplicate/second-half
sampling.
Repeat and duplicate RC samples are submitted
for all holes. The results from these are reviewed
statistically and reported when all data have
been reviewed.
Duplicate core samples were taking at the riffle
split sub-sample stage and at the final split
following pulverization. Duplicates performed
acceptably given thepurpose of the analysis.
Whether sample sizes are appropriate to the grain size of
the material being sampled.
The RC sample size is believed to be appropriate
for the mineralisation style with appropriate
methods used to deal with coarse gold identified
at the project.
Given the identification of coarse gold in the form
of visible gold the full core sample size is
considered fit-for-purpose. The choice of HQ core
was made to provide a large mass sample as
economical for the drill hole.

Criteria Explanation Commentary
Geology Deposit type, geological setting and style of
mineralisation.
The Tampia Hill project area covers a sequence of late
Archaean mafic-felsic granulite facies granitoid and gneiss. The
lowest unit in the sequence as interpreted from the structural
position of the units is a suite of banded feldspar-garnet-
biotite-quartz granulite that also can contain graphite and
pyrrhotite in augen gneiss. The original sequence for this unit
is believed to be clastic sediment, wacke, arenite and graphitic
shale. The next unit stratigraphically above is a mafic feldspar-
biotite-amphibole-pyroxene granulite that appears to contain
a mixture of sedimentary and mafic precursor lithologies.
Stratigraphically above this unit is a banded felsic feldspar-
biotite-quartz granulite. The uppermost part of the sequence
consists of a mafic granulite dominated by pyroxene-
plagioclase-amphibole lithologies. Minor biotite, spinel,
enstatite and quartz with pyrrhotite up to 2% also occur. The
precursor lithology is inferred to be tholeiitic basalt. This
sequence is intruded by quartz-feldspar granitoid dykes and
sills that have complex cross-cutting relationships suggesting
multiple phases of emplacement. This entire sequence is
intruded by several unmetamorphosed dolerite dykes that are
thought to be of Proterozoic in age.
Gold mineralisation at Gault is dominantly disseminated
throughout, or concentrated within, pods of hornblende-
biotite-pyroxene and hornblende-biotite-plagioclase within
pyroxene and biotite-bearing mafic granulites. The gold occurs
with disseminated non-magnetic pyrrhotite, arsenopyrite,
chalcopyrite and rare pyrite. Total sulphide contents of
mineralised intersections are between 1% and 3%, with a
maximum estimated 5% sulphide. Sulphides occur along S1
foliation planes and are folded by F1 minor folds.
Mineralisation occurs in elongate to ellipsoidal pods that vary
in size from 1-10 m thick, 50-150 m wide (east-west) and 50-
200 m long (north-south). Four mineralised shoots were
identified in the north Wanjalonar Zone of the prospect, with
another two zones in the central Merino Gold Zone and
southern Leicester Gold Zone. Average grades within a zone
>1g/t Au vary between 1 to 5 g/t Au over 5-10 m intervals. The
northern zone has yielded the best grades with Leicester
showing promisingsigns of additional highgradegold.

The RC contractor, Orlando Drilling, provided a Schramm 450
drill rig and an Atlas Copco E220RC Explorac (Truck). Samples
were collected from a rig mounted Metzke cyclone via a gravity
fed fixed cone splitter. Additional air pressure was used when
necessary from an all-wheel drive auxiliary/boosters supplying
2100cfm at 1000psi.
RC drill samples were collected in two calico bags on either of
the ports of the gravity fed static cone splitter and the excess
sample was collected into a 600mm wide plastic bag. Both
calico bags are pre-numbered with the sample number clearly
visible and the green bag with the bulk reject written with the
metres. At the completion of each metre drilled the driller’s
offsiders collected the calico bags and green bag and placed
them in rows. All calico bags and the total sample were
weighed on the rig to check split accuracy and total
recoveries/metre delineation. This data is recorded on excel
spreadsheet and analysed using graphs to ensure the sampling
system is in control. The geologist then collected a portion of
the bulk sample from the plastic bag using a scoop and sieve.
This portion was sieved, washed, logged and a spoonful saved
in a chip tray into the appropriate metre interval marked on the
chip tray. All data logged was recorded via laptop computer
directly into an excel spread sheet saved on a USB external
drive. A Vanta XRF analyser was used to take one reading every
sample interval. The readings were taken for lengths of 10
seconds per beam for all three beams.
Certified Reference Materials (CRM’s) were inserted regularly
into the RC sample stream at 1:20 ratio. Blanks and duplicates

were taken through expected mineralisation and where
mineralisation is observed at a density of around 10%. Blanks
are inserted at a frequency of 5% through mineralised zones
and at least 1 every 40 samples.
The 5kg RC samples were dried and fine crushed before being
split using a Boyd Rotary splitter to provide a 20% split (800g).
This sub-sample is pulverised and a 50g aliquot is taken for fire
assay. All samples undergo for two types of analysis: 50g Au
Fire Assays with an ICP-OES finish and 4 acid digest ICP-MS
multi element analysis for As, Cu, S, Co and Ni.
The diamond drilling contractor, Terra Drilling, provided a
Boart Longyear KWL 1600 truck mounted diamond drill rig.
Support vehicles included a Hanjin Track Mounted Rod Carrier,
fuel and fresh water truck and a Toyota Hilux light vehicle.
The equipment provided by the contractor was inspected by
the geologist before the start of the drilling campaign and was
deemed to be well maintained, safe and fit for purpose.
All drill holes were pegged as required using a Garmin GPSMAP
78s GPS unit. All holes will be accurately surveyed using a
mmGNSS RTK differential GPS once the program is completed.
The drill rig was positioned and oriented on the drill pad by the
geologist using a geological compass to magnetic azimuth
relevant to the hole and the declination was determined by a
clinometer on the mast of the rig and aligned to 60° - 80°
dependant on the hole requirements. The magnetic declination
in the region is -0.61°.

Data aggregation
methods
In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (e.g. cutting of
high grades) and cut-off grades are usually
Material and should be stated.
Drill intersections include those that have an aggregate of 0.5
g/t Au over at least one metre. Internal dilution below 0.5g/t
was allowed for up to 3m.
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.
Intersection aggregation is typically from 0.5g/t and higher
with up to 3m of internal dilution. Where particularly high
grade influences the grade significantly these grades have been
reported separately to the total intersection grade, e.g. 11m at
13.9 g/t Au from 7m (including 1m at 144 g/t Au).
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
Not applicable.

widths and
intercept lengths

Results.

respect to the drill hole angle is known, its
nature should be reported
Due to the clay lithology the vertical RC holes have been drilled
orthogonally to the general dip and strike of mineralisation.
and it is interpreted they intersections represent true widths.
The diamond holes were designed to collect geological
information. The orientation of the holes varied and were not
planned to intersect perpendicular to mineralisation.
Therefore, it should be noted that thickness reported may not
be true thickness.
If it is not known and only the down hole
lengths are reported, there should be a clear
statement to this effect (e.g. ‘down hole
_length, true width not known’). _

All recent RC drill holes with assays have been included and
significant intercepts have been fairly represented.
Any historic RC and Core intercepts in the holes nearest the
reported holes have all been previously reported.

survey results; bulk samples – size and
method of treatment; metallurgical test

Soil sampling, stream sediment sampling, gravity, magnetics
geophysics and downhole magnetic susceptibility, acoustic
imagery, optical imagery, natural gamma readings, resistivity
and pXRF data have been used to assist the interpretation of
the target areas.
A regional and detailed gravity survey was completed to map
the distribution and extent of potential host rocks for gold
mineralisation at Tampia. The main resource area at Tampia is
associated with a bullseye gravity anomaly that corresponds to
a block of mafic gneiss that hosts the main gold mineralisation
at Tampia. There are several gravity trends mapped by the
detailed gravity that appear to follow known mineralised
trends in the resource area. The gravity data clearly map the
distribution of the mafic gneiss in the region with respect to
granite and felsic gneiss, with the denser mafic gneiss (gravity
highs) having a strong spatial association with anomalous gold
in soil geochemistry anomalies, including the area hosting the
main resource at Tampia. The soil anomalies, mafic units and
gravity trends remain largely untested, but have many
similarities to the known resource area. The gravity map will
be used to plan future exploration and resource extension
drilling.
A metallurgical test work program has been completed to
determine the overall gold recoveries from the main ore types
at Mace. The aim of the program was to identify the
amenability of the Mace supergene gold mineralisation to
gravity and cyanidation processing, whilst examining the
rheological behaviour noting the presence of clays. The gravity
processing gave a recovery of 50%, which confirms the results
of the panned samples, and the CIL recovery at a 180µm grind
was 49.7% for a total recovery of 99.7%. There was fast
leaching (8hr) but slower carbon adsorption (18hr), due to the
presence of slimes. The lime consumption was about 5 kg/t and
the NaCN consumption was 0.5 kg/t. The BBWi for 6mm to
150µm crushes was 13.6 kW.hr/t, which is higher than
expected due to the presence of quartz cobbles in the ore. The
recommended grind for treating the Mace ore is 180µm
although a coarser grind may be possible, depending on CIL
tank design.
Further work The nature and scale of planned further work
(e.g. tests for lateral extensions or depth
extensions or large-scale step-out drilling).
A feasibility study has been conducted on the adjacent Tampia
Gold Resource and has been released. Further development
work will include a scoping study to incorporate the Mace Gold
resource into the Tampia Gold Project miner schedule and
exploration drilling to test extensions to the Mace prospect and
complete infill resource drilling of a selected area of the Tampia
Gold resource.

Database
integrity
Measures taken to ensure that data has not
been corrupted by, for example,
transcription or keying errors, between its
initial collection and its use for Mineral
Resource estimation purposes.
All data was directly entered into digital logging
equipment and imported into the database through
automated scripts, with several levels of validation and
quality control. The integrity of the data is considered of
very high standard. It is fit for the purpose of mineral
resource estimation.
Data validation procedures used. Validation of data was carried out automatically upon
entered of data (auto-controlled data entry fields), when
it was uploaded to the database, and then manually by
the database geologist.
Site visits Comment on any site visits undertaken by
the Competent Person and the outcome of
those visits.
The Competent Person visited the site several times just
before the 2018 drilling campaign. All systems were
properly implemented during the first visit and
subsequent visits were aimed at ongoing quality control
and monitoring of correct implementation of SOPs. All
issues encountered were minor and were resolved on site.
If no site visits have been undertaken
indicate why this is the case.
Site visits were undertaken.
Geological
interpretation
Confidence in (or conversely, the
uncertainty of) the geological interpretation
of the mineral deposit.
There is a high degree of geological confidence in the
geological interpretation of the deposit.
The mineralised trends and hosting rocks have predictable
geometries from section to section, and even though
variability occurs on scales smaller than average drill
spacing, the geological framework at the resolution of the
resource model is robust.
Nature of the data used and of any
assumptions made.
Logging data, multi-element ICP, pXRF and density data
were all used to aid in constructing the geological model.
Assumptions did not have major implications on the
overall geometries of the various geological domains.
Geological continuity is relatively simple to establish from
hole to hole and the deposit is not structurally complex.
The effect, if any, of alternative
interpretations on Mineral Resource
estimation.
In the Competent Person's opinion, alternative
interpretations of the geology are not likely to deviate
much from the current model and will have little to no
impact on the mineral resource.
The use of geology in guiding and controlling
Mineral Resource estimation.
Drill hole lithology was used significantly to guide the
geology interpretation, as the mineralisation related to
lithological contacts.
The factors affecting continuity both of
grade and geology.
Grade continuity is affected by subtle differences in local
pressure and geochemistry conditions.
Geological continuity beyond the paleo-channel deposit is
not yet fully understood. At the eastern part of the
deposit is a mixture of supergene and alluvial
mineralisation and exact boundaries are difficult to
determine. Mainly due to the close proximity of the lode
gold mineralisation at Tampia.
Dimensions The extent and variability of the Mineral
Resource expressed as length (along strike
or
otherwise), plan width, and depth below
surface to the upper and lower limits of the
Mineral Resource.
The deposit measures 700 m along, 200 m across strike
and 30 m deep.
Estimation

techniques
The nature and appropriateness of the
estimation technique(s) applied and key
assumptions, including treatment of
extremegrade values, domaining,

interpolation parameters and maximum
distance of extrapolation from data points.
If a computer assisted estimation method
was chosen include a description of
computer software and parameters used.
The estimation was carried out within domains, aiming to
constrain the interpolation to only relevant samples that
are characterised by the same geological features.
Significant effort was expended to find geological
signatures that would identify and isolate different
mineralised zones, or that would for instance define
drivers for highvs low grade zones.
Surpac, and Supervisor was used for estimation and data
analysis.
See further detailed explanation in the text of the report.
The availability of check estimates, previous
estimates and/or mine production records
and whether the Mineral Resource estimate
takes appropriate account of such data.
The OK estimate was compared and checked with a
polygonal (nearest neighbour) estimate and showed a
reasonable correlation (lower grade, more tonnes), given
the volume-variance effect at a 0 g/t Au cut-off.
The assumptions made regarding recovery
of by-products
No by-products are expected to be recovered.
Estimation of deleterious elements or other
non-grade variables of economic
significance (eg sulphur for acid mine
drainage characterisation)
Not applicable as there are no deleterious elements.
In the case of block model interpolation, the
block size in relation to the average sample
spacing and the search employed.
The block size was set to 10 x 10 x 2 m to honour the data
distribution, with sub-celling set at 5 x 5 x 1 m for volume
resolution at the SMU scale.
Any assumptions behind modelling of
selective mining units.
SMUs were set after preliminary review of mining
parameters and most likely equipment scenarios (surface
miner).
Any assumptions about correlation between
variables.
Correlation between variables have not been assumed or
used in the estimation.
Description of how the geological
interpretation was used to control the
resource estimates
See the main body of the text for a detailed description of
the integration of geology into the resource estimation.
The geological model was used to guide the domaining for
mineralisation; however, no specific geological feature
could be used in combination or in isolation to model the
direct constraint for mineralisation.
Discussion of basis for using or not using
grade cutting or capping.
A grade cap of 64 g/t Au was applied to the high-grade
domain and three samples were capped. This was to
reduce the effect of extreme grades.
The process of validation, the checking
process used, the comparison of model data
to drill hole data, and use of reconciliation
data if available.
The resource was validated by a comparison of top-cut
mean sample values both globally, and within estimation
domains. A visual validation of block model values on
screen compared well globally to input drill hole data. As
expected with ordinary kriging, local validation was
acceptable.
Moisture Whether the tonnages are estimated on a
dry basis or with natural moisture, and the
method of determination of the moisture
content.
Tonnages are estimated on dry tonnage basis and
moisture was not considered.
Cut-off
parameters
The basis of the adopted cut-off grade(s) or
quality parameters applied.
A cut-off grade of 0.1 g/t on the resource blocks at SMU
scale was determined as an appropriate cut-off grade. This
value was determined by preliminary optimisation work,
and by taking into consideration all available geotechnical,
metallurgical, hydrogeological parameters. Various gold
price scenarios were evaluated, with the selected 0.1 g/t
Au cut-off reflecting a gold price of AUD 1675.

Preliminary test work has shown that gravity and
cyanidation are effective for the gold extraction as rapid
and near complete dissolution of gold will result in greater
than 96% gold recovery at relatively moderate cyanide
and low lime consumptions. Any sulphur in the Mace lode
is present as sulphates indicating a low likelihood for
refractoriness in the deposit. Concentrations of arsenic

TAMPIA FEASIBILITY STUDY UPDATE

14 December 2018

Explaurum Limited (ASX:EXU) ( Explaurum or the Company ) is pleased to advise the key outcomes of an updated Tampia Feasibility Study which incorporates further metallurgical test work, mine design and scheduling together with refined capital and operating cost estimates. The updated Feasibility Study also includes the addition of the Mace supergene deposit.

Summary of updated Feasibility Study outcomes[1]

  • Pre-tax NPV of approx. A$156M (up from A$125M) and pre-tax IRR of approx. 70% (up from 47%)

  • Estimated average C1 operating cost of A$825/oz (down from A$885/oz) and all-in-sustaining-cost (AISC) of A$917/oz (down from A$998/oz)

  • Initial capital expenditure to commercial production of approx. A$111M (down from A$119M)

Summary of key changes from May 2018 Feasibility Study

  • Initial capital cost of standalone process plant subjected to competitive tender process

  • Flotation circuit and ultra fine grind (UFG) circuit construction deferred for approximately 15 months after commencement of operations

  • Mine design and mine scheduling optimised, resulting in improved gold recovery during first two years of operations

  • Mace supergene gold Mineral Resource estimate incorporated in mine plan, not requiring additional development capital

Commenting on the results of the updated Feasibility Study, Explaurum Managing Director, John Lawton, said:

"Explaurum undertook to provide shareholders with critical Tampia project information in order to enable a balanced evaluation of the Company within the context of the current Ramelius takeover offer. This updated Tampia Feasibility Study delivers on this commitment and details new and relevant information not previously assessed in the Independent Expert’s Report prepared by BDO.

“The updated Feasibility Study confirms that Tampia is a technically sound and robust project with forecast annual production in excess of 100,000 ounces of gold, at an all-in-sustaining-cost averaging A$917 per ounce. This places Tampia in the lowest cost quartile of gold projects globally. It also generates an outstanding margin of over A$800 per ounce at current spot gold prices, which are trading at A$75 per ounce higher than the gold price used in the updated Feasibility Study.

“We have commenced targeting extensions to the Mace resource, which are planned to be drilled aggressively over the upcoming summer period. This will be coupled with advancing exploration at the highly prospective A8 target to the north.”

1 Note that there has been no change to the Tampia Ore Reserve or Indicated Mineral Resource announced in the May 2018 Tampia Feasibility Study (see ASX release dated 30 May 2018) as part of the updated Feasibilty Study.

Production Target Based Partly on Inferred Mineral Resources

The Production Target referred to in this announcement is based partly (12%) on Inferred Mineral Resources. In compliance with clause 5.16.4 of the ASX Listing Rules, the Company confirms that there is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources, or that the Inferred component of the Production Target (12%) itself will be realised.

The Company notes that the updated Tampia mine and process schedule does not incorporate processing of the Mace Inferred Mineral Resource until after project payback has been forecast to occur.

Forward Looking Statements

Explaurum is pleased to report this summary of the updated Study in a fair and balanced way and believes that it has a reasonable basis for making the forward-looking statements in this announcement, including with respect to any mining of mineralised material, modifying factors, production targets and operating cost estimates.

The Explaurum Board confirms that it has a reasonable basis for the view that the requisite funding for development of the Tampia Gold Project will be available when required. The grounds for this reasonable basis are as outlined in section 4.6(a) of Explaurum’s First Supplementary Target’s Statement (released to the ASX on 24 October 2018).

This announcement has been compiled by Explaurum from the information provided by the various contributors to the updated Study. All financial assumptions and estimates are quoted in Australian Dollars ( A$ or AUD ) only.

KEY OUTCOMES OF UPDATED TAMPIA FEASIBILITY STUDY

Explaurum is pleased to report the findings of the updated Tampia Feasibility Study, based on programs undertaken following completion of the Feasibility Study in May 2018.

Further studies, negotiations with contractors and discussions with consultants have resulted in variations to the May 2018 Feasibility Study outcomes. In particular, the process plant design and specifications, pit design, metallurgical recovery, mining fleet and dry hire costings, mine scheduling and accommodation are all areas that have been further assessed. The key outcomes of this additional study work are summarised below and in Table 1.

Initial capital cost of standalone process plant

The process plant construction has been put out to competitive EPC tender. This process will be completed shortly, but it is currently estimated the total initial capital cost for development will be approximately A$111M, including contingencies ranging from 5% to 10%. Variations from the initial estimate include increases in site buildings, project management team, pre-production, site works and communications, and reductions in the process plant and capital spares.

Deferred construction of flotation and UFG circuit

Metallurgical test work has been undertaken to optimise gold recovery. A revised recovery model has been applied to the Tampia resource that has highlighted that the southern end of the Ore Reserve has lower arsenic (As) content. Consequently this material is capable of processing via standard carbon in leach (CIL), rather than flotation and ultra fine grinding (UFG), while still delivering high forecast LOM recoveries averaging 91.8%. The major capital deferral items are therefore the flotation and UFG circuit (now Year 2 of operations) and outright purchase of the accommodation village.

4 The royalty payable to the Tampia Joint Venture partner has been reduced to 1% of total gold production within the JV tenements

5 AISC includes C1 costs + sustaining capital, royalties, site rehabilitation and head office corporate costs

Mine design and mine scheduling

As a result of defining the different metallurgical character of the southern portion of the Tampia orebody, the mine design was changed to allow mining of this material in the first 12 to 18 months of operations. In addition to allowing deferral of the flotation and UFC circuit construction, this also has the effect of delivering considerably lower forecast operating costs, without the ‘loss’ of any gold production. In addition, low grade/high arsenic material is now planned to be mined and stockpiled, rather than included in the process schedule as previously. This is the key driver of the higher average grade of ore processed, but also the higher strip ratio and slightly lower LOM gold production.

Addition of Mace Supergene Mineral Resource

The Mace deposit has been recently assessed as an addition to the Tampia Gold Project. A new Mineral Resource estimate, reported in accordance with the JORC Code (2012) and classified by a Competent Person,

3

based on 310 RC drill holes totalling 7,403m and 25 diamond drill holes (for 427m), was reported to ASX on 3 December 2018. Mining and processing of a significant component of that Resource is incorporated in the updated Study.[1]

OTHER STUDY DETAILS

The updated Study has been prepared by senior Explaurum staff with substantial input from a number of consultants including:

ALS Metallurgy Pty Ltd Assaying, Mineralogy & Metallurgical Testing
JT Metallurgical Services Metallurgy program management
Kenex Pty Ltd Geology
MBS Environmental Environmental
Metallurgy Pty Ltd Metallurgical Testing
MineComp Mine Design
MinEcotech Pty Ltd Project Management & Mining
RSC Global Pty Ltd Geology and Resource Estimation

The updated Study has assumed an open pit mining operation using an excavator/truck mining fleet and utilising the Tampia standalone processing plant designed for treatment of 1.5Mtpa, but capable of a processing rate of up to 1.9Mtpa on weathered feed such as Mace.

1 The information is extracted from the report entitled ‘Initial Mace Resource Estimate’ released on 3 December 2018 and is available to view here. The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement and that all material assumptions and technical parameters underpinning the estimates in the announcement continue to apply and have not materially changed. The Company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original market announcement.

ADDITIONAL INFORMATION ON MACE

Metallurgical test work was carried out on a composite metallurgical sample of the Mace gold mineralisation to confirm its amenability to gravity and cyanidation processing as well as testing its rheological behaviour due to the presence of clays. All samples originated from a diamond drlling program. The following key findings are made from this test work:

  • Gold extraction is rapid and near complete (+99%) at moderate cyanide and low lime consumptions. Gravity recoverable gold was high between 49-59%;

  • All bulk tests (BLEG and Gravity/Leach tests) displayed an approximate 40% uplift in grade compared to the head assay indicating the presence of free gold and associated sampling/assaying bias when dealing with small masses;

  • The presented composite contained below detectable limits of typical deleterious elements, including arsenic.

Based on the test work, the process flowsheet to be applied to Mace consists of single stage crushing, grinding (SAG mill), gravity circuit, carbon-in-leach (CIL) leaching and electrowinning to produce dore gold for refining in Perth. The flotation, ultra-fine grinding an enhanced leaching sections of the Tampia plant are not required for the Mace feed.

The Tampia financials benefit from the inclusion of the Mace Mineral Resource due to the character of the gold resource being free gold at shallow depth (all of the resource is less than 20m below surface) and hosted by unconsolidated sediments.

Modelling has been based on mining the total resource in the first year of operations and processing on an incremental basis (<100ktpa), with processing only scheduled to commence post the forecast payback period for the project.

Resource Classification

A Mineral Resource model was produced by RSC Global Pty Ltd. The model was based on 10m x 5m x 2m blocks and was created using ordinary kriging methodology with a 0.1 g/t cut-off. The Mineral Resource estimate has been classified in the Inferred category (Table 2). There is no material classified as Indicated or Measured.

Notes:

1. The Mineral Resource is classified in accordance with JORC, 2012 edition

2. The effective date of the Mineral Rresource estimate is 3 December 2018.

3. The Mineral Resource is contained within E70/2132, M70/815 and M70/816

4. Estimates are rounded to reflect the level of confidence in these resources at the present time.

5. All resources have been rounded to the nearest 100,000 tonnes

6. The Mineral Resource is reported at 0.1 g/t Au cut-off grade

Cut-off Grades and Mining Methods

A cut-off grade of 0.3g/t Au on the resource blocks at SMU scale was determined as an appropriate cut-off grade. This value was adopted from the optimisation work carried out on the weathered material at the main Tampia deposit, which has similar metallurgical recovery characteristics and processing costs, and which took into consideration all available geotechnical, metallurgical, hydrogeological parameters. Various gold price scenarios were evaluated, with the selected 0.3 g/t Au cut-off reflecting a gold price of A$1,650oz.

The Mace deposit is planned to be mined conventionally with light blasting and using a 100 t class excavator. This approach is well suited to the nature of the Mace resource and the size, depth and configuration of the open pit.

Mining

Geotechnical Assessment

The slope parameters used for the Mace pit design have been assumed based on work done on the overlapping Tampia Pit design, and allowing for the shallow depth, and very short mine open time, and 100% backfilling.

The initial shallowest northwest stages of the Mace pit will be backfilled with Mace waste earth, while the later stages that lie underneath the footprint of the waste rock dump of the Tampia main pit will be backfilled with Tampia main pit waste.

The weathering is shallow and weakly developed with no fresh rock occurring in the Mace pit. The batter face angle used in the pit design was 60[0] .

A geotechnical study is being commissioned, using structural analysis of diamond drill core and laboratory testing of rock strength and shear strength to assess the physical properties of all lithologies within the proposed pit area.

6

Pit Design

The resource model was supplied to Minecomp for pit design.

No ore loss or dilution were applied for the purposes of the mine planning work.

Due to the shallow depth of the Mineral Resource, the simple ore geometry, and the strong geological controls on the mineralisation, an open pit optimisation study was not required

The Mace pit was manually and interactively designed by MineComp. Blocks above 0.3 g/t that occurred above the oxidation boundary were included in the pit design, though any isolated blocks that would incur a higher stripping ratio were excluded. To ensure access and efficient mining, areas of subgrade or waste were included where necessary in the design. Final access ramp designs were not needed, because operational access will be by temporary or backfilled ramps, or from the adjoining Tampia pit.

The relevant pit design criteria for the Tampia pit were applied to the Mace design, including:

Minimum single lane ramp width 13.9m
Maximum ramp gradient 10%
Berm width 7m
Berm vertical spacing 20m
Maximum mining bench spacing 5m
Weathered pit wall batter slope 60°

A batter angle of 60[0] was applied and, because the pit walls did not exceed 20m depth, no berms were required.

The Mace Gold Resource pit design, outside the Tampia pit, is 600m long, ranging from 50m to 100m wide, and up to 18m deep. The resulting pit design has a waste to ore stripping ratio of 2.1.

The Mace pit design is shown in plan view (Figure 2) and a three dimensional view showing the relationship with the Tampia pit (Figure 3).

Figure 2. Mace pit design, MGA 94 Grid Plan View

The southeastern part of the Mace Mineral Resource occurs within the larger planned Tampia Pit, much of the pit lies underneath the planned Tampia waste rock dump (WRD), with a small north-western part that lies outside the WRD footprint.

Most of the waste mined from Mace is planned to be utilised in construction of the TSF embankment, or as bulk fill in the ROM pad. The NW part, after backfilling with Mace waste, is planned to be reinstated to the original natural terrain and rehabilitated as native vegetation.

==> picture [441 x 253] intentionally omitted <==

The final pit design was evaluated using the resource model with a 0.75 g/t Au high-grade cut and 0.3 g/t Au low-grade cut, and 0.15 g/t Au mineralised waste cut (Table 3).

Mining Schedule

The northwestern part will be mined first, and internally backfilled, followed by the central part. The southeastern portion is included in the Tampia mining schedule.

The Mace pit has been scheduled to be mined simultaneously with the Tampia pit over a six-month period. The Mace mining schedule comprises 100% Inferred Resources.

Mining Operations

The Study assumes technical and managerial direction will be controlled by Explaurum, using a drill and blast contractor, while the load, haul and support operations will be conducted by Explaurum using a fully maintained dry hire mining fleet.

Metallurgy and Processing

Metallurgical test work has been carried out on composited diamond drill samples taken along the Mace paleo channel in the Tertiary sediments and adjacent weathered bedrock in the northwest part of the deposit.

A single composite sample composed of 28 separate 1m mineralised intervals and weighing approximately 110kg was homogenised at <2mm grain size for rheological, gravity and cyanidation test work. A separate composite sample (+2mm – 6mm) was used for ore hardness test work. All leach and rheological test work utilised Tampia site water (Figure 4).

9

==> picture [380 x 438] intentionally omitted <==

Figure 4. Metallurgical test work flow sheet

The key results from the test work were as follows:

  • A significant disparity between assay grade and (higher) recalculated grade in the leach test work caused by the presence of free gold

  • No silver or deleterious elements present (As, Cu, Sb, Te, Hg or C);intensive cyanide leaching resulted in near complete dissolution (99.7%) within 12 hours

  • Bond Ball Work Index (BBWi) of 13.6 kWhr/t conducted on <6mm composite at a closed screen size of 150µm

  • Gravity concentrate (Knelson) ranged between 48.9% and 59.4%

  • Cyanide leach tests were conducted at P80 106µm, 150µm and 180µm with similar recoveries at 106µm and 150µm of over 99%, and slightly slower at 180µm of 97.7%

  • Lime consumption (4.5kg/t) was low and cyanide consumption (0.31kg/t) was moderate

  • Slimes may affect carbon adsorption rates, but the effect can be minimised by reducing feed density or using a viscosity modifier

Test work has confirmed that gravity and cyanidation are effective for the gold extraction as rapid and near complete dissolution of gold will result in greater than 96% gold recovery at moderate cyanide and low lime

consumptions. Any sulphur in the Mace mineralisation is present as sulphates indicating a low likelihood of the deposit being refractory. Concentrations of arsenic and other deleterious elements (copper, antimony, tellurium, carbon and mercury) are low.

(a) Process Plant Design

Processing of oxide ore allows the Tampia process rate to be increased to 1.9Mtpa from 1.6Mtpa, providing the extra plant capacity for treating Mace feed.

Though a grind requirement of only P80 180µm is needed for the Mace feed, the Tampia SAG mill and gravity / CIL circuits can handle 190 tpa at 125µm grind of the harder Tampia feed, so there is ample processing capacity for the added soft Mace feed.

Mace is considered suitable feed for the Tampia weathered ore flow chart, which has sequential gravity, and CIP processing (Figures 5 and 6). A high-intensity cyanide reactor is planned to further treat the gravity concentrate, and conventional elution and gold room processes will produce gold dore bars.

Figure 6. Flow Sheet – CIL leach and Gold Room circuits

(b) Process Plant Operations

The Mace feed has been scheduled for processing on an incremental basis throughout the project processing operations, commencing post the forecast initial payback period for the project.

The mining schedule and the proposed Tampia plus Mace processing plan gives a weathered Tampia ore processing rate of 1.9Mtpa for the first 6 months, reducing to 1.5Mtpa on fresh ore, then subsequently rising again, up to 1.9Mtpa towards the end of the initial project life on the combination of Mace feed plus Tampia Low Grade ore expected scheduled to be treated in those latter phases stage.

The underlying Tampia processed grade estimate assumes a stockpile management strategy where higher grade ore and low arsenic ore is preferentially treated, leaving lower grade ore on the ROM stockpile to be treated when the new ore feed rate drops off near the end of the pit life, and the same approach is applied to the Mace lower grade material.

(c) Tailings Storage Facility (TSF)

Mace will require no change to any aspects of the Tampia Tailings Storage Facility.

Waste material mined from the Mace pit is expected to be good material for the TSF construction.

Project Infrastructure

Mace will require no change to any of the Tampia infrastructure requirements.

12

Environmental Impact and Approvals

Being immediately adjacent to, or overlapping the main Tampia project, Mace has no significant additional environmental impact. Mace will have no change in the impact on the visual amenity.

Subterranean fauna and troglofauna are expected to be present in the Mace groundwater, and to be affected by the mining and pit dewatering. The overall species impact is however expected to be low, because the species have been sampled downstream of Mace, and Mace is located near the upstream limit of the hosting paleochannel.

A waste rock characterisation study has not been done because the Mace ore and waste is redeposited weathered material that is similar to, or more benign than, the weathered lithologies found in the Tampia pit.

Additional test work may be required to assess potential for clay dispersion of the highly weathered Mace waste rock. Test methods would include particle size distribution, Emerson Aggregate Test (clay dispersion) and exchangeable cation (calcium, magnesium, sodium and potassium) measurements.

Mace is not expected to have any significant effect on the environmental approvals process currently underway, because it is fully covered by the completed baseline surveys and is highly integrated with the main project.

The Mace resource covered by this study requires no clearing of native vegetation.

The mining of Mace requires no change to the currently planned Groundwater Licences.

No significant changes to the Tampia Works Approvals and Environmental Licences are required.

No significant changes are required to the Tampia Project Management Plan (PMP) that identifies the hazards and associated risks with the proposed operation from a health and safety perspective.

No significant changes are required to the Tampia Dangerous Goods Licence, nor to the Shire development applications, or building and sewerage Permits.

Social Impact

The Mace study area falls within the Shire of Narembeen Town Planning Scheme 2 on land zoned as, and predominantly used for farming.

Land ownership of the study area is freehold, and the Mace Resource applicable to this Study, is as with all of Tampia, fully within a single ownership.

Native Title and Cultural Heritage

No Native Title applies at Tampia because all property that would be impacted by mine development is privately owned. As with Tampia, there is no Aboriginal and European Cultural heritage present.

Operating Cost Estimate

Mining Costs

The mining operating cost estimate is based on the Tampia Feasibility Study mining cost model for conventional open pit mining using the 100t excavator and 100t trucks.

The Mace ore is very soft but the material properties observed in the diamond core indicate the UCS is too high to be consistently ‘free dig’, and light blasting to loosen the ground for high excavator productivity appears

13

necessary. A blasting powder factor of 0.25 kg/BCM of wet ground emulsion explosive, 102mm diameter holes, and 5m deep blasts has been applied.

The same excavator and truck productivity and costs have been applied as for the weathered zone of the Tampia pit. Because the underlying Tampia mining operation covers the monthly fixed mining costs, and because Mace has a lower stripping ratio, the cost per tonne of ore mined is lower than the equivalent mining cost of Tampia ore.

Incremental Drill & Blast (A$0.81 /BCM) and Load & haul (A$1.47 /BCM) costs have been applied, as shown in Tables 4 and 5.

Table 5. Mace Incremental Load & haul costs

Depth below Surface(m) Mining Cost (A$/bcm) Mining Cost (A$/bcm)

Processing Costs

The processing cost of Mace is based on processing costs in the Tampia Feasibility Study for the 1.6 Mtpa weathered ore processing by gravity CIL throughput of weathered ore. The cost is adjusted for the higher annual throughput (1.9 Mtpa) with the incremental Mace material, and the lower grinding power requirements of the Mace material, giving an incremental CIL processing cost of A$12.96/t.

A large front end loader is proposed to be added to the mining fleet to complement the scheduled loading capacity of the excavators. This machine is also available as a backup ROM loader, and it will be retained on site after the end of mining as the main low-grade loader, allowing the new weathered processing rate to be supported on LG feed.

Administration

The administration cost of Mace is fully covered by the weathered ore processing G&A costs applied to the base load Tampia ore in the Feasibility Study.

Sustaining Costs

There is no required sustaining capital cost required for the six months of mining the Mace Mineral Resource.

14

Because most of Mace underlies the Tampia Waste rock dump (except a small northewestern section) and will be consumed within 6 months of mining, no additional provision for rehabilitation is required.

Corporate

No additional project related corporate costs are required for the mining and processing of the Mace Mineral Resource.

Capital Costs

No additional capital cost is required for the mining and processing of the Mace resource.

Description of the Mineral Resource estimate
used as a basis for the conversion to an Ore
Reserve
The most recent Mineral Resource estimate for Tampia
(April 2018) was used for reporting the Tampia Ore
Reserves (May 2018). Both are unchanged.
Clear statement as to whether the Mineral
Resources are reported additional to, or
inclusive of, the Ore Reserves
Mineral Resources are reported inclusive of Ore Reserves.
Site visits Comment on any site visits undertaken by the
Competent Person and the outcome of those
visits.
If no site visits have been undertaken indicate
why this is the case.
The Competent Person (Engineering) has visited the
Tampia project site on six occasions through 2017 and
2018.
Study status The type and level of study undertaken to
enable Mineral Resources to be converted to
Ore Reserves.
The Code requires that a study to at least Pre-
Feasibility Study level has been undertaken to
convert Mineral Resources to Ore Reserves.
Such studies will have been carried out and
will have determined a mine plan that is
technically achievable and economically
viable, and that material Modifying Factors
have been considered.
A The Ore Reserve statement is based upon the May 2018
Project Feasibility Study.
Financial modelling completed as part of this December
2018 Feasibility Study Update shows that the project
remains economically viable under current assumptions.
Modifying Factors (mining, processing, infrastructure,
environmental, legal, social and commercial) have been
considered during the original Ore Reserve estimation
process and this study Update.
Cut-off parameters The basis of the cut-off grade(s) or quality
parameters applied.
An economic cut-off of 0.30 g/t Au cut-off for weathered
and 0.45 g/t Au cut-off for fresh material was applied to the
Resource modelling from which the Ore Reserve was
estimated.
These cut-off grades were calculated in consideration of
the following parameters: gold price, operating costs,
process recovery, transport and refining costs, general and
administrative costs and royalty costs, and they remain
valid in this Study Update.
Mining factors or
assumptions
The method and assumptions used as
reported in the Pre-Feasibility or Feasibility
Study to convert the Mineral Resource to an
Ore Reserve (i.e. either by application of
appropriate factors by optimisation or by
preliminary or detailed design).
The choice, nature and appropriateness of
the selected mining method(s) and other
mining parameters including associated
design issues such as pre-strip, access, etc.
The

made
regarding
geotechnical parameters (e.g. pit slopes,
stope sizes etc) grade control and pre-
production drilling.
The major assumptions made and Mineral
Resource model used for pit and slope
optimisation (if appropriate).
The mining dilution factors used.
The mining recovery factors used.
Any minimum mining widths used.
The manner in which Inferred Mineral
Resources are utilised in mining studies and
While an allowance for edge dilution was made during the
Tampia Reserve optimisation process with a global dilution
of 2.5% being applied, no dilution has been applied to the
Mace inferred resource.
Metallurgical parameters were applied to the Mace
resource model in order to model product grades and
yields.
Minor and non-material modifications have been made to
the Tampia detailed pit designs with due consideration of
geotechnical, geometric, and access constraints. These pit
designs were used as the basis for production scheduling
and economic evaluation.
Conventional mining methods (truck and excavator), were
selected.
The geotechnical parameters have been applied based on
geotechnical studies.
Inferred Mineral Resources were excluded from the

a measurable positive impact but are not material to the
economic viability of the production schedule.
Metallurgical
and

factors
or
assumptions
The metallurgical process proposed and the
appropriateness of that process to the style of
mineralisation.
Whether the metallurgical process is well
tested technology or novel in nature.
The nature, amount and representativeness
of the metallurgical test work undertaken,
the nature of the metallurgical domaining
applied and the corresponding metallurgical
factors applied.
Any assumptions or allowances made for
deleterious elements.
The existence of any bulk sample or pilot scale
test work and the degree to which such
samples are considered representative of the
orebody as a whole.
For minerals that are defined by a
specification, has the ore reserve estimation
been based on the appropriate mineralogy to
meet the specifications?
Conventional gravity and CIL processing is proposed as the
basis of both the weathered and fresh ore. Fresh ore
processing will also utilise ultra-fine grinding of a flotation
concentrate. All these processes have been successfully
tested at laboratory scale on the Tampia mineralisation
and are currently being used at plant scale in the gold
industry.
Representative samples of mineralisation types suited to
the three processing approaches above have been
obtained by metallurgical diamond drilling and tested in
metallurgical laboratories.
Weathered material was processed initially followed by
fresh material, with fresh ‘low grade’ being stockpiled for
processing at the end of the mine life.
A scheduled plant throughput of 1.9Mtpa is applied to
weathered and fresh low grade feed and a throughput of
1.5Mtpa is applied to the fresh high grade feed.
Environmental The
status
of
studies
of
potential
environmental impacts of the mining and
processing operation. Details of waste rock
characterisation and the consideration of
potential sites, status of design options
considered and, where applicable, the status
of approvals for process residue storage and
waste dumps should be reported.
All primary environmental, heritage and tenure approvals
required under State and Commonwealth legislation are
being progressed.
The mine is to be developed under the Mines Act 1978.
Infrastructure The existence of appropriate infrastructure:
availability of land for plant development,
power, water, transportation (particularly for
bulk commodities), labour, accommodation;
or the ease with which the infrastructure can
be provided or accessed.
Tampia minesite is readily accessible from Perth by
multiple sealed highways and Shire graded roads locally.
The workforce will be housed in Company accommodation
in Narembeen on a drive-in drive-out (DIDO) basis.
Infrastructure is plentiful and readily available in the
region.
The mine development will be on private land acquired by
the Company. Power and water supply studies have
identified appropriate solutions for mining operations.
Costs The derivation of, or assumptions made,
regarding projected capital costs in the study.
Projected capital costs have been provided predominantly
based on quoted estimates by specialist suppliers as well as
current knowledge and industry experience where
applicable.
The methodology used to estimate operating
costs.
Operating cost estimates were developed by Explaurum
from first principles, based on a dry hire mining and
contract drill and blast model, and updated to reflect
current operating costs.
Allowances made for deleterious elements. Gold mineralisation at Tampia is associated with arsenic
which may affect metallurgical recovery and have
environmental consequences. These issues were fully
addressed in the Feasibility Study and there are no material
changes.
The source of exchange of exchange rates
used in the study.
Capital cost estimates for process plant and infrastructure
are made in 2018 Australian dollars, using an exchange rate
of USD:AUD = 0.75 where applicable.
Derivation of transportation charges.
The basis for forecasting or source of
treatment and refining charges, penalties for
failure to meet specification etc.
Gold dore transportation and refining charges at the Perth
Mint Refinery have been used in the Study.

The gold price assumed for LOM operations is A$1650 oz.
The price has been set by the Company based on a 5 year
historic average price of A$1600 oz. The A$1650 price
assumes a LOM USD:AUD exchange rate of 0.75.

is economically viable with a positive Net Present Value
(NPV). A discount rate of 8% has been used in the financial
analysis, and the inflation rate has been assumed at 0%,
with a fixed price for gold produced through LOM.

Classification The basis for the classification of the Ore
Reserves into varying confidence categories.
Whether the result appropriately reflects the
Competent Person’s view of the deposit.
The proportion of Probable Ore Reserves that
have been derived from Measured Mineral
Resources (if any).
The estimated Ore Reserve is based on the underlying
Mineral Resource classification of Indicated and Inferred
Mineral Resources. Consequently, the Ore Reserve
estimate consists entirely of Probable Reserves in
accordance with JORC Code (2012) guidelines.
There are no Probable Ore Reserves derived from
Measured Mineral Resources and no Inferred Mineral
Resources are included in the Ore Reserve.
The Competent Person is satisfied that the stated Ore
Reserve classification reflects the outcome of technical and
economic studies.
Audits or reviews The results of any audits or reviews of Ore
Reserve estimates.
The Ore Reserve estimate was prepared by AMC based on
inputs from a number of other independent consulting
groups and EXU personnel. The estimate has subsequently
been externally reviewed by CSA Global with no fatal flaws
identified.
