GIDGEE GOLD PROJECT
RESOURCE ESTIMATION – WHISTLER AND MONTAGUE GOLD DEPOSITS
Immediately subsequent to quarter-end, Gateway Mining Limited (ASX: GML) ( Gateway or Company ) reported a maiden JORC 2012 Inferred Mineral Resource estimate (MRE) for the Company’s 100%-owned Gidgee Gold Project , Western Australia (Figure 1). This initial Mineral Resource position represents the first step in what is expected to be an ongoing process of resource growth and upgrade, over the short to medium term.
The reported Mineral Resource that comprises a total Inferred Resource of 3.425 million tonnes grading 2.2g/t Au 240,000 ounces of contained gold , relates to the Whistler Gold Deposit and Montague Gold Deposit , which are both located on the prospective margin of the Montague Granodiorite. The two Resources are located approximately 800m apart (see Figure 1). The Montague Resource has a component of quartz-stockwork gold mineralisation in the base of the historical open pit, which is now referred to as the Boulder Gold Deposit.

The completion of a maiden resource for these two key deposits represents an important first step in the Company’s strategy to develop a new large-scale gold project at Gidgee. The resources set a strong initial foundation for the Company to unlock the broader potential of this highly prospective emerging gold project.
RESOURCE SUMMARY
The maiden MRE for the Gidgee Gold Project is 3,425,000 tonnes @ 2.2g/t for 240,000 ounces of contained gold[1] and is summarised in Table (1) and additional detail is provided in Appendices 2-4:

RESOURCE EXPANSION AND EXPLORATION – Whistler and Montague Gold Deposits
To advance the resource expansion and exploration push, a major new drilling program of ~16,000m of Reverse Circulation and air-core drilling has now commenced at the Gidgee Gold Project. A significant component of this program will be focused on expanding the Whistler and Montague Gold Deposits.
Whistler Gold Deposit
An opportunity exists to aggressively target a significant expansion of the Whistler Gold Deposit beyond the reported Mineral Resource. The gold deposit remains open in all directions, with immediate strong potential to extend the mineralisation along strike to the north and south, down-plunge and in a series of separate flat-lying structures that have recently been discovered.
The greater Whistler mineralised trend has been defined by shallow drilling over a strike length of approximately 1.25km.
==> picture [360 x 262] intentionally omitted <==
Figure (6): Whistler Long Section – Exploration Targets for current drilling program
Montague Gold Deposit
The Montague Gold Deposit remains open in all directions and is potentially part of a mineralised system consisting of multiple flat-lying shear zones with the mafic volcanic rock package and quartz-stockwork zones on the margin of the granodiorite. The prospective contact zone remains largely untested to the north and south for approximately 2.2km.
ACHILLES EXPLORATION TARGET
In addition to the Company’s main focus of exploration and resource expansion activities at the Whistler and Montague Gold Deposits, the Achilles Project has been identified as a high-priority target to be tested in the upcoming drilling programs[2] .
Cautionary Statement
The Exploration Targets reported within this announcement are not Mineral Resources. The potential quantity and grade of the Exploration Targets are conceptual in nature and there has been insufficient exploration to determine a Mineral Resource. There is no certainty that additional exploration work will result in the estimation and reporting of Mineral Resources.
Gateway has now completed a full evaluation and interpretation of the Achilles Exploration Target, which is located on the highly prospective margin of the Montague Granodiorite (Figure 7).
2 See ASX Announcement 3 October 2019: Major new expansionary drilling programs underway at Gidgee Gold Project following Maiden Resource
4
The generation of this Exploration Target has involved the validation of all historical drilling data and then applying new structural and stratigraphic concepts built on the recent work at both the Whistler and Montague Gold Deposits.
This work by the Company has highlighted the potential of the Achilles Exploration Target to advance rapidly to a JORC 2012 compliant Mineral Resource with additional drilling.
The Achilles Exploration Target incorporates the previously separate NE Caledonian, Rosie North, S-Bend, AF1 Lode and Rosie Prospects. In total, the target extends for a strike length of approximately 1.5km and now comprises an estimated Exploration Target of 1.2 Mt to 3.4 Mt at 2.3g/t to 3.4g/t for 88,000oz and 370,000oz of contained gold.

KEY POINTS – Assumptions and Methodologies
-
All drilling results utilised to derive the Achilles Exploration Target are historical in nature and were completed both by Gateway (pre-2018) and the previous owners of the Gidgee Gold Project. Drilling information has been verified where possible in relation to locational accuracy, sampling protocols and analytical quality control procedures. The drilling data comprises a combination of Reverse Circulation (RC), diamond and rotary air blast (RAB).
-
A total of 55 drill holes have intersected the mineralised shear zones of interest. A complete list of these intercepts and a JORC Table (1) are provided as Appendices 6, 7 and 8.
-
The potential size and contained ounces of gold of the Exploration Target are presented in Table 2 as a range of values, which in the Competent Person’s opinion, represent a reasonable approximation based on the level of available information and estimation methodologies applied.
-
The Exploration Target consists of four mineralised structures that have previously been considered distinct and separate. It is now understood that these structures are part of a greater structural domain and are likely to be interlinked by additional structures. The NE Caledonian, Rosie North, S-Bend, AF1 Lode and Rosie Prospects are the component structures that now make up the current Achilles Exploration Target (Figure 8).
-
The Rosie North, S-Bend and the AF1 lodes are largely sub-vertical, north-striking shear zones hosted in the mafic volcanic rocks on the immediate margin of the Montague Granodiorite. Where the mineralised structure intersects the granodiorite it is typical that a broader quartz stockwork zone is also developed.
-
The NE Caledonian shear zone is relatively flat-lying (30 degrees) and extends from the immediate base of the historical shallow open pit. The mineralisation is typified by quartz veins within a strongly sheared and foliated mafic volcanic rock host sequence. The geometry and style of mineralisation is very similar to that seen at the Montague Gold Deposit which is located 800m to the immediate north.
-
The estimation process was based on assessing the potential for mineralisation amenable to shallow mining techniques to a depth of approximately 100m and making an assessment on the potential for higher-grade mineralisation to a depth of 200m below surface.
-
In the top 100m, either from surface or from the base of the historical open pits, in-house modeling of the gold mineralisation has been completed where it is partially defined by drilling. This work has not been reported as a Mineral Resource Estimation at this point due to insufficient drill spacing and the inclusion of a component of RAB drilling.
-
From 100-200m an assessment was made of high-grade domain characteristics within the existing drilling. Width and grades were adjusted and projected to an arbitrary depth of 200m.
-
An average specific gravity of 2.65 was applied to all of the exploration target. This is based on recent information collected from the resource estimation process at Whistler and Montague.
-
A range of reported outcomes were based on both depths below surface and grade variation (See Table within Appendix 7 for detailed workings)[3] .

DETAILED GRAVITY SURVEY
During the reporting period Gateway completed a detailed ground-based gravity survey over the majority of the Gidgee Gold Project as part of its ongoing commitment to unlock the Project’s potential as a Tier-1 gold exploration and development opportunity[4] .
The investment of time and money into collecting high-quality technical datasets provides a key platform for efficient and effective exploration and reflects Gateway’s commitment to technical excellence and the adoption of a systematic approach to exploration that leverages off the full range of available exploration methodologies.
Importantly, the Montague Granodiorite can be accurately modelled using gravity methods, providing the Company with a relatively effective and efficient exploration targeting strategy by allowing it to pinpoint the location of the prospective contact over its tenements.
Gravity surveys has proven to be an invaluable exploration targeting approach at other granite-hosted gold deposits in Western Australia such as Red 5’s King of the Hills deposit.
The gravity data will be integrated with existing geophysical, geochemical and geological datasets to provide a key platform for the Company’s ongoing targeting processes at Gidgee.
KEY POINTS
-
The detailed ground gravity survey provides a high-quality dataset that clearly and precisely maps out the prospective contact of the Montague Granodiorite (Figures 9 and 10).
-
Accurate positioning of the targeted contact allows for more effective planning of drilling programs.
-
Modeling of the contact in 3D will provide a key understanding of the contact geometry at depth.
-
The data provides greater clarity on the key structures interpreted to control the gold mineralisation across the wider Gidgee Gold Project.
-
The data, particularly when integrated with the airborne magnetic data, allows for targeting of intrusions similar to the Montague Granodiorite that have not previously been identified in the region. These intrusions would be considered as high-ranking targets for future programs of exploration.
-
In addition to the Montague analogue targets, gold deposit styles based on Kanowna Belle and Wallaby are considered as viable targets throughout the wider Gidgee Gold Project and will be actively targeted.
-
Historical exploration has identified a significant volcanic hosted massive sulphide (VHMS) copper-zinc-gold system at the Flametree Prospect. This new gravity dataset can now be utilised to help identify sub-volcanic intrusions that would help focus any future exploration initiative targeting base metals.
GRAVITY SURVEY DETAILS
-
The survey data was collected by Atlas Geophysics Pty Ltd, a Perth based geophysical contracting company.
-
Gravity measurements were acquired using Scintrex CG-5 AUTOGRAV Gravity Meters (SN: 276 and 410811).
-
GPS positions were acquired using CHC Nav i70 Base receiver and CHC i70 GNSS Rover Receivers.
-
Gravity data was acquired on a nominal grid of 200m x 200m station spacing with 100m X 100m infill acquired over high priority areas.
-
Gravity and GPS data were independently reviewed and verified by Southern Geoscience Consultants Pty Ltd.

TENEMENTS
There have been no material changes to the Company’s tenement holdings during the reporting period (see Appendix 1).
CORPORATE
Appointment of Technical Director
Subsequent to the reporting period, Gateway announced that it appointed highly experienced Australian mining executive Mark Cossom as Executive Technical Director subsequent to the Quarter[5] . Mr Cossom commenced employment with the Company on 21 October 2019. The appointment reflects Gateway’s commitment to establish a strong in-house technical team with project evaluation and development capability as it advances its flagship Gidgee Gold Project in Western Australia to the next level.
Mr Cossom is a highly regarded geologist and mining executive with a strong background in gold exploration and mining geology, coupled with strong economic evaluation and corporate experience. He played a key part of the team that helped transform Doray Minerals from a junior gold explorer to an ASX-200 gold miner, holding a range of senior positions with the company including as Geology-Development Manager from 2010-2015 and General Manager – Geology and Exploration from 2015 to 2019 (prior to its takeover by Silver Lake Resources).
Prior to his time at Doray, Mr Cossom worked as Principal Geologist (SE Asia) for Harmony Gold Ltd based in Brisbane, overseeing all exploration and mine geology activities across the region including for the major Morobe Mining Joint Venture with Newcrest Mining Ltd in PNG. He has also worked in a range of roles for Harmony Gold at their South Kal Operations and for Dioro Exploration as Technical Support Manager.
Mr Cossom holds of Master of Science (Mineral Economics) from the WA School of Mines and a Bachelor of Science (Honours) in Applied Geology from Curtin University.
Capital Raising
During the quarter, the Company successfully completed a capital raising of A$3.46 million (before costs) ( Placement ) to institutional, professional and sophisticated investors to underpin a major new phase of drilling and exploration at its flagship 100%-owned Gidgee Gold Project in Western Australia.
The new phase of drilling will focus on a range of high-priority targets ranging from advanced, resource-level to greenfields opportunities – all aimed at establishing Gidgee as a substantial new Australian gold development project .
The Placement, which comprised the issue of 230,966,664 shares at an issue price of $0.015 per share, was strongly supported by existing and new investors including, subject to shareholder approval, by the Company’s Directors.
As the participation of the Company’s directors in the Placement is subject to shareholder approval, the Placement will be issued in the following two tranches:
-
210,966,664 shares to institutional, professional and sophisticated investors using the Company’s capacity under ASX Listing rule 7.1 and Listing Rule 7.1A ( Tranche 1 Shares ); and
-
20,000,000 shares to Directors of the Company or their nominees, subject to shareholder approval being obtained at a general meeting of shareholders ( Tranche 2 Shares ).

APPENDIX (2): SUMMARY OF GIDGEE GOLD PROJECT MINERAL RESOURCE ESTIMATE
Whistler
Geology, Geological Interpretation and Mineralisation
The Whistler Gold Deposit, within Gateway Mining Ltd’s Gidgee Project is located approximately 630km NE of Perth and 70km north of Sandstone within mining tenement M57/217.
The geology at Whistler comprises of a basalt-granodiorite contact with granodiorite to the west and basalt and minor gabbro dykes to the east, with the mafic rocks being saprock to fresh at the water level. The contact dips steeply west and strikes 345°, and is relatively undeformed at both ends of the pit. The basalt on the east wall is intruded by two gabbro dykes oriented 55-90°→095°. The granodiorite is intruded by a swarm of 1-15m thick biotite-lamprophyre dykes oriented 85-90°→110-115°.
The ore zone at Whistler consists of an en echelon array of NNE-striking veins that cut across a N-S striking, 70° west-dipping foliation which is hosted predominantly in the granodiorite unit.
Drill hole Database
The drill hole database provided for the Whistler deposit contains data for 341 individual drill holes. A restriction has been applied to the database for the estimation of Whistler between the MGA northings of 6,967,900mN and 6,968,400mN and MGS eastings of 751,350mE and 752,000mE. Auger, air core (AC), rotary air blast (RAB) and water bore drill holes have been excluded.
In total, 45 diamond drill holes (DDH) for a total of 7,031.45m and 72 Reverse Circulation (RC) drill-holes for a total of 15,568m have been utilised in the Mineral Resource estimate.
The surface drill hole sections have been predominately drilled on an azimuth of ~270 degrees, with a general dip of -60 degrees. Approximately four historic drill holes were drilled ~090 degrees with a general dip of -60 degrees.
Sampling
Drilling at Whistler was historically drilled by CRA Exploration (1987-1989) and positioned on a grid with a nominal spacing of 20x25m. Verification of data was conducted from open file annual reports. Diamond core was generally half cut sampled over 1m downhole intervals, with infrequent sampling of up to 2m. RC samples were riffle split on 1m downhole intervals. All CRA samples were analysed via 50g fire assay method, a proportion of samples were also analysed for multi-elements.
Gateway RC sampling: 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. A second 2kg-3kg sample was collected at the same time as the original sample. This sample was stored on site and retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags.
Gateway Diamond sampling: Core was drilled by DDH1 Drilling Pty Ltd. Sample lengths were dominantly 1m in length, but where geological contacts were present, the core was sampled to this contact creating a sample less or greater than 1 metre. Minimum sample length was 0.2m and the maximum sample length was 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio.
Assaying
CRA analysed all drill holes by AAS assay at 1-metre intervals. Where the value exceeded 0.5 g/t Au the sample was re-analysed by 50g fire assay. Where the fire assay exceeded 3 g/t Au or where spotty gold was suspected, the sample was re-analysed by screen fire assay. The protocol for a given sample was that screen fire assays were better than fire assays which were in turn better than AAS assays. For all resource/reserve calculations fire assays and screened fire assays only were used.
Gateway drill samples were submitted to ALS (Perth). All samples were analysed by a 50g fire assay (AAS finish) which is a total assay. Ore zones were also submitted for accelerated cyanide leachwell test work. This is involved a 2000g leach with AAS finish.
Field duplicates were collected at a rate of 1:25 with CRM’s inserted at a rate of 1:25 also. The grade ranges of the
12
CRM’s were selected based on grade populations.
Resource Estimation
(a) Geological Modelling
Geological and mineralisation wireframes have been generated inhouse by creating lithology wireframes and applying a cutoff grade of 0.3 g/t Au.
The geological and weathering wireframes have been generated in LeapFrog Geo implicit software from logged lithology and oxidation records.
(b) Variography
Variography has been completed in Supervisor 8.7 software on a grouped domain basis where enough data is present. Domains with too few composites have borrowed variography.
Variograms have been modelled using the following approach:
-
All variograms are standardised to a sill of one;
-
The nugget effect has been modelled from the true downhole variogram;
-
Variograms have been modelled using two or three-structure nested spherical variograms;
-
The variograms have been evaluated using normal scores transforms rather than traditional variograms. This method produces a clearer image of the ranges of continuity, especially in skewed datasets;
-
All variogram models have been standardised to a sill of one. The nugget and sill values have been back-transformed in Supervisor to traditional variograms using the discrete Gaussian polynomials technique.
(c) Block Model Estimation
Grade estimation of gold g/t has been completed using Ordinary Kriging (OK) into 29 mineralised domains using Maptek Vulcan 11.0.2 software. Grade assignment of gold at 0 g/t has been undertaken in unestimated blocks only.
Top cutting of grade has not been assigned to any of the assays for the Whistler mineral resource estimation. This affects a single Domain and is not considered material to the total inferred resource. The Domain has a noted amount of coarse visible gold and is considered geological distinct from the rest of the resource and as such a decision was made to not to apply a top-cut. Additional drilling will be required in this Domain to confirm the full characteristics of the gold prior to any increase in resource confidence levels.
(d) Block Model Construction
The block model parent block size is 12.5m (X) by 12.5m (Y) by 5m (Z). A sub-block size of 0.5m (X) by 0.5m (Y) by 0.1m (Z) has been used to define the mineralisation edges, with the estimation undertaken at the parent block scale.
-
Pass 1 estimations have been undertaken using a minimum of 8 and a maximum of 30 samples into a search ellipse which ranges of 25m (Dir 1) by 25m (Dir 2) by 15m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 2 estimations have been undertaken using a minimum of 8 and a maximum of 30 samples into a search ellipse which ranges of 50m (Dir 1) by 50m (Dir 2) by 30m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 3 estimations have been undertaken using a minimum of 4 and a maximum of 30 samples into a search ellipse which ranges of 100m (Dir 1) by 100m (Dir 2) by 60m (Dir 3). No sample per drill hole limit has been applied.

The following bulk densities have been applied to the resource estimation model:
| Domain / Lithology | Weathering | Bulk Density Assigned t/m3 |
|---|---|---|
| Waste dumpfill | NA | 1.4 |
| Basalt | Oxide | 1.8 |
| Granodiorite | Oxide | 1.8 |
| Biotite Schist | Oxide | 1.8 |
| Basalt | Fresh | 2.9 |
| Granodiorite | Fresh | 2.7 |
| Biotite Schist | Fresh | 2.8 |
High grade yields have been applied in three domains in order to reduce the smearing of high grades during estimation.
(e) Resource Classification
Classification of the Whistler Mineral Resource estimate has been completed in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the JORC Code, as prepared by the Joint Ore Reserve Committee of the AusIMM, AIG and MCA and updated in December 2012).
All classifications and terminologies have been adhered to. All directions and recommendations have been followed, in keeping with the spirit of the code. The categories of Mineral Resource as outlined by the code are as follows;
-
Measured - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.
-
Indicated - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence.
-
Inferred - tonnage, grade, and mineral content can be estimated with a reduced level of confidence.
The resource classification has been applied to the Mineral Resource estimate based on the drilling data spacing, grade and geological continuity, and data integrity. The resource has been classified on the following basis;
-
The Measured Mineral Resource classification has not been applied to the Whistler mineral resource estimate;
-
The Indicated Mineral Resource classification has not been applied to the Whistler mineral resource estimate. Whilst drill spacing is sufficient, the limited documented hardcopy assay data reports and documented geological information reduces the confidence of the resource to lower than Indicated;
-
An Inferred Mineral Resource has been defined by a nominal drill spacing of 25m by 25m, to 25m by 50m.
(f) Mineral Resource Optimised Pitshell
The current in situ, drill-defined resource inventory for the Whistler Deposit has been reported inside an optimized pit-shell at a cut-off of 0.5g/t Au at a gold price of AUD $2,400. The pit-shell has been generated in Whittle by Mining Plus by applying the costs/gold price.

Montague
Geology, Geological Interpretation and Mineralisation
The Montague Gold Deposit, within Gateway Mining Ltd’s Gidgee Project is located approximately 630km NE of Perth and 70km north of Sandstone within mining tenement M57/98.
The historic open cut pit is interpreted to comprise of two domains of mineralisation, separated by a NW-SE striking fault. The western extent of the pit contains WSW dipping mineralisation of the Montague Lode, and the eastern extent containing SSE dipping Boulder mineralisation.
The Montague and Gordon’s Lode is hosted entirely within a shallow westerly dipping biotite schist which displays significant sericite alteration on the hangingwall margin. This unit is hosted within the aphyric basalt unit on the western margin of the granodiorite. The Boulder lode is hosted entirely within the granodiorite unit.
Drill Hole Database
The drill hole database provided for the Montague deposit contains data from 371 individual drill holes. A restriction has been applied to the database for the estimation of Montague between the MGA northings of 6,967,550mN and 6,966,500mN and MGA eastings of 750,500mE and 751,500mE. Auger, air core (AC), rotary air blast (RAB), Grade Control (GC) and water bore drill holes have been excluded.
In total, 7 diamond drill holes (DDH) for a total of 1,668.9m and 364 Reverse Circulation (RC) drill-holes for a total of 18,886m have been utilised in the Mineral Resource estimate.
The surface drill hole sections have historically been drilled vertically while the more recent Gateway drilling has been drilled both vertically and with an azimuth of 090 degrees and a dip of -60. The more recent drilling has been targeting the shallow dipping Montague mineralized structure.
Sampling
Historic mining of the Boulder lode is reported recovering 7076.4 tonnes @ 19.9g/t Au from 1906 to 1913 underground “room and pillar stoping in a shallowly dipping main lode” (Clackline Ltd NOI report, mp 15, pg3, 1988). Operations drilling conducted by Herald Resources (1986-88) located south of the Boulder surface workings, contain downhole lengths where assays are missing from the hardcopy reports. It is unclear as to whether the samples were assayed or whether stoping was encountered during drilling. Due to the level of ambiguity with these samples, these drill holes were omitted from this resource estimation process.
From the documented assays, Herald Resources RC and diamond sampling was conducted over 1m intervals.
15
Gateway RC sampling: 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. A second 2kg-3kg sample was collected at the same time as the original sample. This sample was stored on site and retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags.
Gateway Diamond sampling: Core was drilled by DDH1 Drilling Pty Ltd. Sample lengths were dominantly 1m in length, but where geological contacts were present, the core was sampled to this contact creating a sample less or greater than 1 metre. Minimum sample length was 0.2m and the maximum sample length was 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio.
Assaying
Herald Resources RC and diamond sampling was conducted over 1m intervals and submitted to Pilbara Laboratories for a 50g fire assay analysis.
Gateway drill samples were submitted to ALS (Perth). All samples were analysed by a 50g fire assay (AAS finish) which is a total assay. Ore zones were also submitted for accelerated cyanide leachwell test work. This is involved a 2000g leach with AAS finish.
Field duplicates were collected at a rate of 1:25 with CRM’s inserted at a rate of 1:25 also. The grade ranges of the CRM’s were selected based on grade populations.
Resource Estimation
(g) Geological Modelling
Geological and mineralisation wireframes have been generated inhouse by creating lithology wireframes and applying a cutoff grade of 0.5 g/t Au.
The geological and weathering wireframes have been generated in LeapFrog Geo implicit software from logged lithology and oxidation records.
(h) Variography
Variography has been completed in Supervisor 8.7 software on a grouped domain basis where enough data is present. Domains with too few composites have borrowed variography.
Variograms have been modelled using the following approach:
-
All variograms are standardised to a sill of one;
-
The nugget effect has been modelled from the true downhole variogram;
-
Variograms have been modelled using two or three-structure nested spherical variograms;
-
The variograms have been evaluated using normal scores transforms rather than traditional variograms. This method produces a clearer image of the ranges of continuity, especially in skewed datasets;
-
All variogram models have been standardised to a sill of one. The nugget and sill values have been back-transformed in Supervisor to traditional variograms using the discrete Gaussian polynomials technique.
(i) Block Model Estimation
Grade estimation of gold g/t has been completed using Ordinary Kriging (OK) into 21 mineralised domains using Maptek Vulcan 11.0.2 software. Grade assignment of gold at 0 g/t has been undertaken in unestimated blocks only.
Top cutting of grade has not been assigned to any of the assays for the Montague mineral resource estimation. The mafic volcanic hosted domains have a recognized nugget effect however the higher grades are considered to be representative on a geological basis. Additional drilling will be required in the mafic volcanic hosted Domains to confirm the full characteristics and distribution of the gold prior to any increase in resource confidence levels.
(j) Block Model Construction
16
The drill hole data spacing is typically 20m by 20m with areas of extensional drilling at 80m by 80m in the down-dip and along-strike extents.
The block model parent block size is 10.0m(X) by 10.0m (Y) by 5.0m (Z). A sub-block size of 2.0m (X) by 2.0m (Y) by 0.5m (Z) has been used to define the mineralisation edges, with the estimation undertaken at the parent block scale.
-
Pass 1 estimations have been undertaken using a minimum of 8 and a maximum of 20 samples into a search ellipse which ranges of 72m (Dir 1) by 30m (Dir 2) by 24m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 2 estimations have been undertaken using a minimum of 8 and a maximum of 20 samples into a search ellipse which ranges of 120m (Dir 1) by 50m (Dir 2) by 40m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 3 estimations have been undertaken using a minimum of 4 and a maximum of 20 samples into a search ellipse which ranges of 120m (Dir 1) by 50m (Dir 2) by 40m (Dir 3). No sample per drill hole limit has been applied.
The following bulk densities have been applied to the resource estimation model:
| Domain / Lithology | Weathering | Bulk Density Assigned t/m3 |
|---|---|---|
| Waste dumpfill | NA | 1.4 |
| Basalt | Oxide | 1.8 |
| Granodiorite | Oxide | 1.8 |
| Biotite Schist | Oxide | 1.8 |
| Basalt | Fresh | 2.9 |
| Granodiorite | Fresh | 2.7 |
| Biotite Schist | Fresh | 2.8 |
High grade yields have been applied in seven domains in order to reduce the smearing of high grades during estimation.
(k) Resource Classification
Classification of the Montague Mineral Resource estimate has been completed in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the JORC Code, as prepared by the Joint Ore Reserve Committee of the AusIMM, AIG and MCA and updated in December 2012). All classifications and terminologies have been adhered to. All directions and recommendations have been followed, in keeping with the spirit of the code. The categories of Mineral Resource as outlined by the code are as follows;
-
Measured - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.
-
Indicated - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence.
-
Inferred - tonnage, grade, and mineral content can be estimated with a reduced level of confidence.
The resource classification has been applied to the Mineral Resource estimate based on the drilling data spacing, grade and geological continuity, and data integrity. The resource has been classified on the following basis;
-
The Measured Mineral Resource classification has not been applied to the Montague mineral resource estimate;
-
The Indicated Mineral Resource classification has not been applied to the Montague mineral resource estimate. Whilst drill spacing is sufficient, the limited documented hardcopy assay data reports, historic missing assay data, ‘nugget effect’ associated with the Montague domain and limited documented geological information reduces the confidence of the resource to lower than Indicated;
17
- An Inferred Mineral Resource has been defined by a nominal drill spacing of 20m by 20m to 80m by 80m in the down-dip and along strike extents.

APPENDIX (3): JORC Code 2012 Edition Table (1) Reporting of Sampling, Exploration Results and the Estimation and Reporting of Mineral Resources for the Whistler Gold Deposit.
| 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. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • 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 samples from which 3 kg was pulverized to produce a 30 g 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. |
• DIAMOND Drilling– Core was drilled by DDH 1. Gateway staff collected the core from the rig and took the core back to the core yard where the core was cleaned, reassembled and marked up with metre marks for logging by Gateway geologists. The geologist marked up the core for sampling and the HQ and NQ core was half cut in half using a corewise automatic core saw. Sample lengths were dominantly 1m in length, but where geological contacts were present, the core was sampled to this contact creating a sample less or greater than 1 metre. Minimum sample length is 0.2m and maximum sample length is 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio • RC drilling - 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. Once the metre was completed, the drill bit was lifted off the bottom of the hole, to create a gap between samples, when the gap of air came into the collection box the top shutter was closed off. Once the top shutter was closed, the bottom shutter was opened, and the sample was dropped under gravity thorough a Metzke cone splitter. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. A second 2kg-3kg sample was collected at the same time the original sample. This sample has been stored on site. These duplicate samples have been retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags. • The bulk sample from the waste was collected in wheelbarrows and dumped into neat piles on the ground. • During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. • Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges. Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. |

| Diamond Drilling:HQ3 and NQ core drilled in fresh rock. Core orientated and mineralised noted and marked for cutting. Sample lengths sampled on 0.5 to 2m intervals and cut to half-core sub-sample collected. Samples were analysed for Au by AAS technique with results greater than 0.5ppm Au re- assayed by Fire Assay. Assays >3g/t Au re-assayed by Screen Fire Assay. This methodology was applied to account for a recognized coarse gold component within the mineralised zones. RC Drilling:Samples were collected on 1m intervals, riffle split and 5m composite samples prepared for assay. Re-assays were undertaken on selected 1m samples. Analysis was carried out by Australian Laboratory Services and Sheen Analytical Services. All holes were cased with 50mm PVC to facilitate downhole geophysical logging. |

| 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.). |
• DIAMOND - was drilled by DDH1 (Perth) using a Boart Longyear KWL 1600H drill rig. • RC – Challenge Drilling drill rig was used. The rig consisted of a Schramm truck mounted RC rig with 1150cfm x 350psi on board compressor, an Airsearch 1800cfm x 900psi on board Booster, and a truck mounted Sullair 900cfm x 350psi auxiliary compressor. Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. Diamond Drilling:RC percussion or HQ3 pre-collars were drilled to fresh rock. NQ core drilled for remainder of holes. No details available on drilling rig specifications. RC Drilling:RC percussion drilled as pre-collars to fresh rock. No details available on drilling rig specifications. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximize sample recovery and ensure representative nature of the samples. • 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. |
• DIAMOND – the holes were rough cored from surface through the broken oxide zone which is well understood from previous drilling. The remnant core was examined by Gateway Geologists and then discarded. Once coherent coring was established the drill sample recovery was measured routinely by Gateway Geologists. Overall recovery was excellent. • During the RC sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. From this process showed that the majority of ore grade samples had recoveries greater than 80% • Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. • At the end of each metre the bit was lifted off the bottom to separate each metre drilled. • The majorityof samples were ofgoodqualitywithground water havingminimal |

• Diamond core was put into core trays on the drill rig and then cleaned, reassembled and marked up with metre marks for logging by Gateway geologists • Reverse circulation chips were washed and stored in chip trays in 1m intervals for the entire length of each hole. Chips were visually inspected and logged to record lithology, weathering, alteration, mineralisation, veining and structure. • Data on rock type, deformation, colour, structure, alteration, veining, mineralisation and oxidation state were recorded. • Logging is both qualitative and quantitative or semi quantitative in nature. Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. Reverse circulation chips were washed and stored in chip trays in 1m intervals for the entire length of each hole. Chips were visually inspected and logged to record lithology, weathering, alteration, mineralisation, veining and structure. Records of samples being wet or dry were taken. Diamond core was presented and stored in industry standard core boxes. The core was orientated and core loss noted. Data on rocktype, deformation, colour, structure, alteration, veining, mineralisation and oxidation state were recorded. RQD, magnetic susceptibility and core recoveries were recorded. Logging is considered both qualitative and quantitative or semi-quantitative in nature. The logging information is considered to be fit for purpose. |

| 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. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • 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 samples from which 3 kg was pulverized to produce a 30 g 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. |
• DIAMOND Drilling– Core was drilled by DDH 1. Gateway staff collected the core from the rig and took the core back to the core yard where the core was cleaned, reassembled and marked up with metre marks for logging by Gateway geologists. The geologist marked up the core for sampling and the HQ and NQ core was half cut in half using a corewise automatic core saw. Sample lengths were dominantly 1m in length, but where geological contacts were present, the core was sampled to this contact creating a sample less or greater than 1 metre. Minimum sample length is 0.2m and maximum sample length is 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio • RC drilling - 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. Once the metre was completed, the drill bit was lifted off the bottom of the hole, to create a gap between samples, when the gap of air came into the collection box the top shutter was closed off. Once the top shutter was closed, the bottom shutter was opened, and the sample was dropped under gravity thorough a Metzke cone splitter. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. A second 2kg-3kg sample was collected at the same time the original sample. This sample has been stored on site. These duplicate samples have been retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags. • The bulk sample from the waste was collected in wheelbarrows and dumped into neat piles on the ground. • During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. • Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges.

| Diamond Drilling:HQ3 and NQ core drilled in fresh rock. Core orientated and mineralised noted and marked for cutting. Sample lengths sampled on 0.5 to 2m intervals and cut to half-core sub-sample collected. Samples were analysed for Au by AAS technique with results greater than 0.5ppm Au re- assayed by Fire Assay. Assays >3g/t Au re-assayed by Screen Fire Assay. This methodology was applied to account for a recognized coarse gold component within the mineralised zones. RC Drilling:Samples were collected on 1m intervals, riffle split and 5m composite samples prepared for assay. Re-assays were undertaken on selected 1m samples. Herald Resources RC and diamond sampling was conducted over 1m intervals and submitted to Pilbara Laboratories for a 50g fire assay analysis. There are several instances with the historic MOA prefixed RC holes where the assay results are missing from the historic hardcopy reports. GML believe that the assay results are missing as opposed to the drill hole not being analysed. These missing intercepts are recorded as -99 in the database and these holes were omitted from the inferred resource model. |

• DIAMOND – the holes were rough cored from surface through the broken oxide zone which is well understood from previous drilling. The remnant core was examined by Gateway Geologists and then discarded. Once coherent coring was established the drill sample recovery was measured routinely by Gateway Geologists. Overall recovery was excellent. • During the RC sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. From thisprocess showed that the majorityof oregrade samples |

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| 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. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • 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 samples from which 3 kg was pulverized to produce a 30 g 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. |
• Historic Gateway RC drilling (GRC pre-fix) - 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. Once the metre was completed, the drill bit was lifted off the bottom of the hole, to create a gap between samples, when the gap of air came into the collection box the top shutter was closed off. Once the top shutter was closed, the bottom shutter was opened, and the sample was dropped under gravity thorough a Metzke cone splitter. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. A second 2kg-3kg sample was collected at the same time the original sample. This sample has been stored on site. These duplicate samples have been retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags. • The bulk sample from the waste was collected in wheelbarrows and dumped into neat piles on the ground. • During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. • Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges. • Historic Gateway RAB drilling (GRB – prefix) was conducted by Bordec Drilling. All analysis was completed by Genalysis Laboratories, Perth. Submitted samples comprised 2kg speared parent samples which were subjected to total preparation. Au by B/ETA to 1ppb. Ag,As Co,Cu,Ni Sb and Zn by B/AAS to 1ppm. Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases.

• 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.). |
• RC – Challenge Drilling drill rig was used. The rig consisted of a Schramm truck mounted RC rig with 1150cfm x 350psi on board compressor, an Airsearch 1800cfm x 900psi on board Booster, and a truck mounted Sullair 900cfm x 350psi auxiliary compressor. • RAB Drilling – Bordec Drilling completed all of Gateway’s historic RAB drilling programs Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. Diamond Drilling:RC percussion or HQ3 pre-collars were drilled to fresh rock. NQ core drilled for remainder of holes. No details available on drilling rig specifications. RC Drilling:RC percussion drilled as pre-collars to fresh rock. No details available on drilling rig specifications. |

• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximize sample recovery and ensure representative nature of the samples. • 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. |
• During the RC sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. From this process showed that the majority of ore grade samples had recoveries greater than 80% • Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. • At the end of each metre the bit was lifted off the bottom to separate each metre drilled. • The majority of samples were of good quality with ground water having minimal effect on sample quality or recovery. • From the collection of recovery data, no identifiable bias exists. Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. |

| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drill lines were orientated perpendicular to the perceived strike of the mineralized structure. Inclined RC holes (-60 degrees) are perpendicular to the dip of the mineralized structure creating minimal sampling bias. The vertical RC holes are around 20-30 degrees off being perpendicular to the dip in the mineralised structure creating a minimal sampling bias. • Historical Drilling: All information referred in this report not collected in this current program has been accessed through verifying historical company reports and/or available digital databases. The majority of holes have been drilled at a 60 to 90 degree dip and intersected the mineralisation at an appropriate angle. In some cases reverse angled holes have been completed to test for short range controls on the gold mineralisation. The orientation of the drilling is suitable for the mineralisation style and orientation of the mineralisation at the Whistler, Montague and Caledonian Targets. |
