WMG’s main focus for the period continued to be the flagship Mulga Tank Ni-Cu-PGE Project where results further validate the discovery of a major nickel sulphide mineral system. Assay results from holes MTD026 and MTD027 were received during the quarter, with results from MTD027 being the best results to date at the project (ASX, MTD027 Best Assay Results Yet at Mulga Tank, 4 October 2023). The results highlight multiple broad intersections of disseminated nickel sulphide mineralisation which cumulatively totalled: MTD026 840m at 0.28% Ni, 140ppm Co, 103ppm Cu, 24ppb Pt+Pd with S:Ni 1.6 MTD027 694m at 0.31% Ni, 141ppm Co, 68ppm Cu, 30ppb Pt+Pd with S:Ni 1.0 Western Mines Group Ltd Level 3, 33 Ord Street West Perth WA 6005 ASX:WMG Telephone: +61 475 116 798 Email: contact@westernmines.com.au www.westernmines.com.au Shares on Issue: 62.55m Share Price: $0.29 Market Cap: $18.14m Cash: $1.87m (30/09/23) 1 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 Whilst the visible disseminated mineralisation, confirmed by assay results, clearly demonstrates extensive Type 2 Mt Keith-style nickel sulphide mineralisation, there is increasing evidence of a likely Type 1/2 hybrid nickel sulphide mineral system more akin to Perseverance-style mineralisation (basal massive sulphide component). This includes numerous examples of remobilised massive sulphide veinlets throughout the Complex, visible larger in-situ immiscible sulphide globules in holes MTD026 and MTD027, and assay results suggesting possible Perseverance-style heavily disseminated “cloud” sulphide at depth in hole MTD027: MTD027 96m at 0.40% Ni, 161ppm Co, 99ppm Cu, 43ppb Pt+Pd from 1,208m inc. 38m at 0.56% Ni, 159ppm Co, 105ppm Cu, 65ppb Pt+Pd from 1,262m inc. 8m at 1.11% Ni, 181ppm Co, 143ppm Cu, 91ppb Pt+Pd from 1,270m Towards the end of the quarter the Company commenced an initial 18 hole (subsequently expanded to 22 holes) reverse circulation (RC) drilling program (ASX, RC Drilling Program Commences at Mulga Tank, 20 September 2023; RC Drilling Expansion and Drilling for Equity, 17 October 2023). The 22 hole program, totalling approximately 6,600m, aims to test the extent of the shallow disseminated nickel sulphide mineralisation observed across the centre of the Mulga Tank Ultramafic Complex. The holes are spread over a 2,500m x 1,000m area in the centre of the main body of the Complex, at approximately 500m x 300m spacing, and will attempt to drill to ~300m target depth. As a complementary technique to the ongoing drilling programs, the Company engaged Expert Geophysics to undertake a MobileMT survey at Mulga Tank. MobileMT (Mobile MagnetoTellurics) is the latest innovation in airborne electromagnetic technology and the most advanced generation of Airborne Natural Source Audio Frequency Magnetotelluric (AFMAG) technologies. This deep resistivity mapping tool aims to further unlock the 3D architecture of the Complex and target accumulations of massive nickel sulphide (ASX, Completion of MTD026 and Upcoming MobileMT Survey, 27 June 2023). The survey was conducted across the entire Mulga Tank Complex and parts of the surrounding Minigwal Greenstone Belt. The survey is complete and initial results have been received but the Company is still waiting on final 3D inversion modelling results (ASX, Completion of MobileMT Survey at Mulga Tank, 8 August 2023). During the period Powder X-Ray Diffraction (XRD) analysis performed on a series of reconnaissance samples taken from Mulga Tank drill core resulted in the identification of the mineral brucite (Mg(OH)2) as well as Hydrotalcite Group minerals. These minerals have been implicated in the passive sequestration of atmospheric CO2 in mine tailings at several locations worldwide, and in particular, tailings from the giant, dunite-hosted Mt Keith nickel deposit in Western Australia. The results significantly enhance the “green” credentials of the project, with tailings generated via a conventional crush, grind and flotation processing route being amenable to relatively rapid sequestration of atmospheric carbon via carbon mineralisation processes - producing NetZero Carbon Nickel, along with the possibility of a carbon credit by-product revenue stream. At the end of the quarter the Company announced the acquisition of neighbouring tenement E39/2134 at Mulga Tank from Dynamic Metals Limited (ASX:DYM). This bolt-on acquisition consolidates the entire Mulga Tank Ultramafic Complex, now 100% owned by WMG. The acquisition consideration was $20,000 cash, 100,000 ordinary shares, 200,000 options over ordinary shares and a 1% Net Smelter Royalty. Limited exploration work was undertaken on the Company’s other projects during the period whilst the Company focused on all the various Mulga Tank exploration programs. ASX:WMG www.westernmines.com.au 2 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 PROJECT OVERVIEW Figure 1: Map of WMG project locations MULGA TANK The Mulga Tank Project comprises exploration licences E39/2132, E39/2134 and E39/2223 and exploration licence application E39/2299, covering the Minigwal Greenstone Belt, 190km east-northeast of Kalgoorlie. The Minigwal Greenstone Belt is a NNW trending linear sequence of predominantly mafic and ultramafic lithologies; it is very under explored due to the presence of shallow sand cover and presents a “frontier” exploration opportunity for major Ni-Cu-PGE and orogenic gold deposits. WMG has been undertaking continuous drilling programs at the Mulga Tank Project since November 2022, with exciting exploration results demonstrating significant nickel sulphide mineralisation and an extensive nickel sulphide mineral system within the Mulga Tank Ultramafic Complex (ASX, MTD023 Assays Confirm Discovery of Significant Nickel Sulphide System, 5 April 2023; MTD026 Assays - 840m of Nickel Sulphide Mineralisation, 30 August 2023; MTD027 Expands Mineralisation 4km Across Mulga Tank, 28 August 2023). ASX:WMG www.westernmines.com.au 3 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 A second multipurpose RC drill rig commenced a systematic shallow drilling program across the centre of the main body of the Complex in September looking to build on these results to date (ASX, RC Drilling Program Commences at Mulga Tank, 20 September 2023). RECENT DIAMOND DRILLING RESULTS Diamond holes MTD027 and MTD028 were completed during the quarter (ASX, MTD027 Expands Mineralisation 4km Across Mulga Tank, 28 August 2023; MTD028 Further Nickel Sulphides at Mulga Tank, 2 October 2023). Hole MTD027 is located on the eastern side of the Mulga Tank Complex in an area that has had no previous drilling. The hole was designed to test a coincident gravity and magnetic high, a minor MLEM anomaly, and for the presence of nickel sulphide mineralisation in this area. The hole was drilled to a total depth of 1,662.3m, the deepest hole drilled at the project, and intersected ~1,500m of variably serpentinised and talc-carbonate altered high MgO meso to adcumulate dunite ultramafic (84-1,630.9m), beneath 84m of sand cover (0-84m), before encountering a footwall of basalt and silicified shales at 1,630.9m depth (1,630.9-1,662.3m). The dunite was divided by an approximately ~39m thick dolerite unit (728-766.8m) that most likely represents a later dyke/sill. This dolerite unit is becoming something of a marker horizon and was seen at a nearly identical depth and thickness in holes MTD023 (EIS1) (~1.7km to WNW) and MTD026 (EIS2) (~1km to WSW). Disseminated magmatic sulphides (trace to 2%) were observed at numerous intervals down the hole, starting from around 216m depth. In a number of places the disseminated sulphides coalesced into interstitial blebs (3 to 5% sulphide) between former olivine crystals. Frequent intersections of high-tenor in-situ nickel sulphide globules and remobilised massive nickel sulphide veinlets were also observed down the length of the hole. A number of good examples of high-grade nickel sulphide material filling fractures in the rock were seen, including shallow examples in the top 200m of the hole. This is a very positive observation, in a new previously undrilled area, and opens up the eastern margin in the search for massive sulphide sources or deposits within the Complex (Perseverance-style basal massive sulphide) and not just limited to the western margin where previously encountered. Hole MTD028 is located on the western side of the Mulga Tank Complex between previous holes MTD022 and MTD023 (EIS1). The hole was designed to test the continuity of mineralisation between these holes, possible association of mineralisation with magnetic highs and also further test the large W Conductor EM anomaly at depth. The hole was drilled to a total depth of 1,107.5m and intersected ~950m of variably serpentinised and talccarbonate altered high MgO meso to adcumulate dunite ultramafic (75-1,040.3m), beneath 75m of sand cover (0-75m), before encountering the usual footwall assemblage of black shale, basalt and silicified shales at 1,040.3m depth (1,040.3-1,107.5m). The upper ~300m of the dunite was divided by three basalt-dolerite dykes/sills (one larger ~30m and two smaller <5m). These may correspond to the dolerite unit seen at around ~730m depth in holes MTD023 (EIS1), MTD026 (EIS2) and MTD027 but in a shallower position. The western portion of the Complex is interpreted to be fractured into fault blocks and these may be relatively uplifted versus the eastern portion of the Complex. ASX:WMG www.westernmines.com.au 4 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 Disseminated magmatic sulphides (trace to 2%) were observed at numerous intervals down the hole, starting from around 138m depth. In a number of places the disseminated sulphides coalesced into interstitial blebs (3 to 5% sulphide) between former olivine crystals. A number of intersections of high-tenor remobilised massive nickel sulphide veinlets were also observed in the deeper portion of the hole, similar to those seen in surrounding holes MTD012, MTD013, MTD022 and MTD022W1, and MTD023 (EIS1). This continues to confirm the basal contact of the Complex to be highly prospective for massive sulphide accumulations. Overall hole MTD028 showed similarities with the two neighbouring holes MTD022 (~600m to the W) and MTD023 (EIS1) (~500m to the WSW). Similar intersections of disseminated sulphides were observed to MTD023 (EIS1) occurring in four broad zones, though visible mineralisation was perhaps somewhat masked by the structural overprint in this area and the presence of the shallow later stage basalt-dolerite dykes/sills. A number of examples of remobilised massive sulphide veinlets were logged in the deeper portion of the hole furthering confirming the prospectivity of the basal contact of the Complex for massive sulphide accumulations. GEOCHEMICAL ASSAY RESULTS Assay results for holes MTD026 (EIS2) and MTD027 were received during the period (ASX, MTD026 Assays 840m of Nickel Sulphide Mineralisation, 30 August 2023; MTD027 Best Assay Results Yet at Mulga Tank, 4 October 2023). The results show prospective high-temperature adcumulate-extreme adcumulate dunite host rock down the length of both holes, averaging 48.4% MgO, 0.25% Al2O3 (volatile free), over a cumulative 1,374.5m for MTD026 (EIS2) and 47.8% MgO, 0.31% Al2O3 (volatile free), over a cumulative 1,501m for MTD027. Multiple broad intersections of disseminated nickel mineralisation with elevated Ni and S, in combination with highly anomalous Cu and PGE, show strong evidence for an extensive “live” magmatic nickel sulphide mineral system, and confirm the visual observations. Significant mineralised intersections include: MTD026 130m at 0.31% Ni, 136ppm Co, 122ppm Cu, 24ppb Pt+Pd from 116m inc. 13m at 0.35% Ni, 142ppm Co, 301ppm Cu, 65ppb Pt+Pd from 157m and 158m at 0.27% Ni, 136ppm Co, 70ppm Cu, 19ppb Pt+Pd from 262m and 38m at 0.28% Ni, 136ppm Co, 64ppm Cu, 16ppb Pt+Pd from 448m and 104m at 0.24% Ni, 139ppm Co, 100ppm Cu, 22ppb Pt+Pd from 500m inc. 16m at 0.40% Ni, 175ppm Co, 157ppm Cu, 45ppb Pt+Pd from 528m and 32m at 0.31% Ni, 177ppm Co, 250ppm Cu, 30ppb Pt+Pd from 660m and 258m at 0.26% Ni, 135ppm Co, 95ppm Cu, 24ppb Pt+Pd from 792m and 32m at 0.31% Ni, 149ppm Co, 95ppm Cu, 15ppb Pt+Pd from 1,092m and 53m at 0.34% Ni, 149ppm Co, 136ppm Cu, 40ppb Pt+Pd from 1,154m and 35m at 0.38% Ni, 159ppm Co, 113ppm Cu, 32ppb Pt+Pd from 1,154m Which cumulatively total: 840m at 0.28% Ni, 140ppm Co, 103ppm Cu, 24ppb Pt+Pd ASX:WMG www.westernmines.com.au 5 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 And: MTD027 64m at 0.27% Ni, 133ppm Co, 55ppm Cu, 17ppb Pt+Pd from 122m 38m at 0.32% Ni, 154ppm Co, 114ppm Cu, 44ppb Pt+Pd from 210m 30m at 0.34% Ni, 157ppm Co, 112ppm Cu, 46ppb Pt+Pd from 290m 100m at 0.32% Ni, 136ppm Co, 49ppm Cu, 30ppb Pt+Pd from 430m 118m at 0.29% Ni, 136ppm Co, 60ppm Cu, 25ppb Pt+Pd from 578m 130m at 0.24% Ni, 127ppm Co, 81ppm Cu, 22ppb Pt+Pd from 894m 96m at 0.40% Ni, 161ppm Co, 99ppm Cu, 43ppb Pt+Pd from 1,208m inc. 38m at 0.56% Ni, 159ppm Co, 105ppm Cu, 65ppb Pt+Pd from 1,262m inc. 8m at 1.11% Ni, 181ppm Co, 143ppm Cu, 91ppb Pt+Pd from 1,270m 78m at 0.36% Ni, 139ppm Co, 40ppm Cu, 30ppb Pt+Pd from 1,450m 40m at 0.33% Ni, 151ppm Co, 18ppm Cu, 37ppb Pt+Pd from 1,556m Which cumulatively total: 694m at 0.31% Ni, 141ppm Co, 68ppm Cu, 30ppb Pt+Pd In addition to the extensive Mt Keith-style disseminated mineralisation seen in the holes several remobilised massive nickel sulphide veinlets and in-situ immiscible sulphide globules (MTD027), were also observed. Assay results confirm Ni-Cu-PGE mineralisation in the veinlets and the possible nearby presence of massive sulphide accumulations: MTD026 0.5m at 1.21% Ni, 490ppm Co, 1,455ppm Cu, 93ppb Pt+Pd from 116.5m 0.3m at 1.88% Ni, 846ppm Co, 762ppm Cu, 214ppb Pt+Pd from 224.3m MTD027 1.0m at 1.05% Ni, 290ppm Co, 111ppm Cu, 110ppb Pt+Pd from 504m RC DRILLING PROGRAM An initial 18 hole (subsequently expanded to 22 hole) RC drilling program commenced towards the end the period, designed to systematically test the lateral continuity of shallow disseminated nickel sulphide mineralisation observed in the main body of the Mulga Tank Ultramafic Complex (ASX, RC Drilling Program Commences at Mulga Tank, 20 September 2023; RC Drilling Expansion and Drilling for Equity, 17 October 2023). The holes are spaced at approximately 500m x 300m and look to cover a 2,500m x 1,000m area across the centre of the Complex. Each hole is designed to a target depth of ~300m, for a total of around 6,600m - of which the top ~60m of each hole, or ~1,300m in total, is mud-rotary drilling through the sand cover. The planned RC holes are intended to systematically test the central area surrounding diamond holes MTD012MTD022-MTD023-MTD026-MTD027, to confirm if the shallow mineralisation observed is laterally continuous between the holes and whether richer zones of disseminated mineralisation can be found. At the date of this report, 18 holes have been completed and the remaining 4 holes have all been pre-collared through the sand cover down to ~60m depth. The program has so far proved successful with all but two holes reaching the 300m target depth, and a number of holes extended beyond this where visible disseminated mineralisation continued.

MobileMT is the latest innovation in airborne electromagnetic technology and the most advanced generation of Airborne Natural Source Audio Frequency Magnetotelluric (AFMAG) technologies. MobileMT utilises naturally occurring electromagnetic fields in the 25Hz to 20,000Hz frequency range and is essentially a high-resolution deep resistivity and conductivity mapping tool capable of delivering 3D geoelectrical information down to >1km depth - that should effectively target the entire Mulga Tank Complex and basal contact, based on WMG’s geological model. The survey was completed during the quarter (ASX, Completion of MobileMT Survey at Mulga Tank, 8 August 2023) and whilst preliminary results have been received, the Company is still waiting on final 3D inversion modelling from a third party. As well surveying the main body of the Complex within tenement E39/2132 the Company took the opportunity to fly the entire Complex and interpreted komatiite channels within WMG’s northern tenement application E39/2299 and subsequently acquired neighbouring tenement E39/2134 (acquisition details below). ASX:WMG www.westernmines.com.au 8 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 This survey is another step in the Company’s systematic exploration strategy and use of cutting edge technologies at the Mulga Tank Project. Combined with the Company’s existing 3D datasets, such as magnetics, gravity and the extensive geological information gained from the recent deep EIS holes, the deep resistivity and conductivity mapping provided by the MobileMT system will unlock further insight into the Complex and help target massive nickel sulphide deposits. Figure 4: Mulga Tank MobileMT survey area ASX:WMG www.westernmines.com.au 9 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 RECONNAISSANCE XRD MINERALOGICAL ANALYSIS Powder X-Ray Diffraction (XRD) analysis performed on a series of reconnaissance samples taken from Mulga Tank drill core resulted in the identification of the mineral brucite (Mg(OH)2) as well as Hydrotalcite Group minerals. These minerals have been implicated in the passive sequestration of atmospheric CO2 in mine tailings at several locations worldwide, and in particular, tailings from the giant, dunite-hosted Mt Keith nickel deposit in Western Australia. Forsterite and serpentine minerals (the main gangue minerals in Mulga Tank nickel sulphide-bearing dunite) are known to react relatively rapidly with CO2 compared to other silicate minerals, however, brucite and several members of the Hydrotalcite Group of minerals react orders of magnitude faster than forsterite or serpentine under atmospheric conditions, and can thereby help mitigate the carbon output of a mine in realistic timeframes. Recently published work by Lu et al. (2022) estimated that an average brucite content of between 1.7 and 5.9 weight percent in mine tailings is required to make a mine carbon neutral if this brucite is allowed to react with atmospheric CO2. Although only a small group of samples were analysed as part of this first pass study, the results demonstrate that the mineralogy of Mulga Tank Ultramafic Complex contains critical components which could partially or entirely mitigate the output of atmospheric CO2 generated in future mining activities. The presence of brucite and Hydrotalcite Group minerals may result in any tailings generated via a conventional crush, grind and flotation processing route being amenable to relatively rapid sequestration of atmospheric carbon via carbon mineralisation processes - thereby significantly enhancing the “green” credentials of the project by producing NetZero Carbon Nickel, along with the possibility of a carbon credit by-product revenue stream. CONSOLIDATION OF THE ENTIRE MULGA TANK ULTRAMAFIC COMPLEX Just after the end of the quarter WMG entered into a binding agreement to acquire 100% of neighbouring tenement E39/2134 held by Dynamic Metals (ASX:DYM), contiguous to the Company’s current Mulga Tank project area. The acquisition expands WMG’s project area to 425km2, covering approximately 37km strike and the entire under explored Minigwal Greenstone Belt (ASX, WMG Consolidates Entire Mulga Tank Complex, 3 October 2023). The new ground contains a number of interpreted ultramafic bodies thought to represent potential komatiite channels emanating from the main Mulga Tank dunite intrusion. These interpreted ultramafic bodies have never been drill tested but are very likely extensions of the komatiite sequences drilled by WMG in the Panhandle area of the Mulga Tank Complex. WMG’s recent holes MTD016 and MTD024 and historical hole MTD006 show these komatiite sequences contain evidence for high-grade nickel sulphide mineralisation (ASX, First Assay Results Confirm Ni-Cu-PGE Mineralisation, 15 August 2022) and could potentially host Kambalda-style massive nickel sulphide deposits. These komatiite channels are interpreted to extend through the new tenement E39/2134 and up into WMG’s northern tenement application E39/2299 (Figure 5). Acquisition consideration of $20,000 cash, 100,000 fully paid ordinary shares in the Company, 200,000 options over ordinary shares (with an exercise price of $0.60 per share, exercisable 3 years from the date of issue) and a 1% Net Smelter Royalty. ASX:WMG www.westernmines.com.au 10 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 Figure 5: Mulga Tank acquisition of tenement E39/2134 DISCUSSION It was a pretty incredible quarter for the Company. Having demonstrated a major nickel sulphide mineral system at Mulga Tank with our first EIS hole MTD023 in the previous quarter, the Company backed this up with better results from MTD026 (EIS2) and a further deep hole MTD027. Combined, the drilling to date at the project highlights an extensive magmatic nickel sulphide mineral system within the Mulga Tank Ultramafic Complex. Significant Type 2 Mt Keith-style disseminated nickel sulphide mineralisation has been demonstrated across the majority of the main body of the Complex, over some ~4km. Broad intervals of shallow disseminated nickel sulphide mineralisation, within the top 250 vertical metres, have now been seen across diamond drill holes MTD012-MTD022-MTD023-MTD026-MTD027 approximately 3.5km apart. In order to test the continuity and extent of this mineralisation the Company commenced a shallow RC drilling program during the period. The 22 hole program, over an area of approximately 2,500m x 1,000m, aims to test a volume of around 600,000,000 cubic metres (assuming the 300m target depth of drilling and ~60m of sand cover) in the central part of the main body. Mineralisation, in the top 250 vertical metres, could potentially be amenable to large scale open pit mining, especially considering the top 50-90m of sand cover is essentially “free-dig”, easily removable overburden. Whilst, the ~500m x ~300m drill spacing is unlikely to be sufficient for JORC compliant inferred resource it is hoped to generate an initial exploration target for shallow Mt Keith-style mineralisation. ASX:WMG www.westernmines.com.au 11 ASX RELEASE | QUARTERLY ACTIVITIES REPORT SEPTEMBER 2023 JASPER HILL The Jasper Hill Project comprises exploration licences E39/2073, E39/2079 and prospecting licence application P39/6267. The project is located approximately 80km southeast of Laverton and covers part of the poorly exposed Merolia Greenstone Belt, a NNW trending belt, up to 20km wide, that can be traced over 110km in a SSE direction from the Burtville Mining Centre. The project area is lightly explored, due to being partly under shallow cover, but is contiguous to the historical producing mines of Lord Byron (160,000oz at 1.0g/t Au) and Fish (87,000oz at 4.1g/t Au). Jasper Hill is the Company’s primary gold project containing a mineralised gold trend over 3km strike. The Company as completed field reconnaissance work involving geological mapping, high-resolution ground magnetic survey and locating historical drill collars significant aboriginal heritage sites. The Company plans to complete a litho-structural interpretation and drill targeting work, to advance the project ready for an initial RC drilling program. The Company engaged remote sensing specialists Earthscan Pty Ltd to complete satellite based remote sensing work over the project area, using ASTER multispectral imagery. This work focused on mapping alteration signatures of possible gold targets. Numerous new and existing alteration targets were identified by the work which will be ground-truthed during the next field visit.

The project is located approximately 25km NW of Paynes Finds and lies at the south-eastern end of the Yalgoo-Singleton Greenstone Belt, within an area known as the Warriedar Fold Belt that comprises a folded sequence of gabbro and dolerite intercalated with basalt, ultramafics, sediments and BIF. The Warriedar Fold Belt hosts a number of historic gold workings at the Pinyalling Mining Centre, 3km north of the tenement area, as well as the Baron Rothschild prospect drilled by Thundelarra Exploration during the 1990s. The Company engaged remote sensing specialists Earthscan Pty Ltd to complete satellite based remote sensing work over the project area, using ASTER multispectral imagery. This work was principally focused on mapping pegmatite sequences that could potentially host lithium mineralisation. The Company notes the upswing in lithium focused exploration in the area at Golden State Mining’s (ASX:GSM) nearby Paynes Find Lithium Project (ASX:GSM, Lithium Exploration and Drilling Update, 22 December 2022). An initial field reconnaissance visit is planned to ground-truth these interesting early results is planned in the coming weeks.

The project is located approximately 50km north-northeast of Southern Cross and lies on the western side of the Koolyanobbing Greenstone Belt, a northwest trending sequence of mafic and ultramafic volcanic and intrusive rocks with lesser sediments intercalated with BIF horizons forming prominent ridges. The BIF horizons have been exploited since the 1960s, with several open pit iron ore mines that are currently owned by Mineral Resources (ASX:MIN). Historical rock chip samples from Jock’s Fury show anomalous results of up to 0.74% Ni, 0.11% Cu and 0.22g/t Pt+Pd over 140m strike. BHP drilled several shallow holes at Jocks Fury in the late 1960’s including H202 intersecting 4.6m at 1.28% Ni, 597ppm Cu, 293ppm Co from 42.7m to the end of hole (EOH) and H273 intersecting 16.8m at 0.78% Ni, 360ppm Cu, 285ppm Co from 12.2m, including 3.1m at 1.60% Ni, 865ppm Cu, 700ppm Co from 24.4m. No exploration work was done on the project during the quarter. The Company continues to wait on the grant of tenement application E77/2746, containing Jock’s Fury, in order to comm
