Commenting on the RC assay results, WMG Managing Director Dr Caedmon Marriott said:

“Some great assay results to start the new year with three more holes taking our RC ‘hit rate’ to 19 out of 20 holes received to date showing broad zones of nickel sulphide mineralisation. This latest batch returned a couple of intersections over 1% Ni in holes MTRC006 and MTRC007. These holes were located on the southern boundary of the central-eastern area tested by the drilling - demonstrating the mineralisation be open in this direction. Infilling and extending this zone will likely be a focus of our drilling programs planned for this year.”

MULGA TANK RC DRILLING PROGRAM

Exploration results from the Company’s various drilling programs at the Mulga Tank Project over the last 12 months have demonstrated 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 ).

The Company completed a 22 hole RC drilling program designed to systematically test the lateral continuity of the shallow, uppermost zone of disseminated nickel sulphide mineralisation observed in the Company’s diamond holes MTD012, MTD022, MTD023, MTD026, MTD027 and MTD028 within the main body of the Mulga Tank Ultramafic Complex ( ASX, Completion of 7000m RC Drilling Program at Mulga Tank, 7 November 2023 ) (Figure 1).

The holes were spaced at approximately 500m x 300m and cover a 2,500m x 1,000m area across the centre of the Complex. Each hole was designed to a target depth of ~300m, which was achieved in all but three holes, for a total of 7,035.5m - of which the top ~60m of each hole, or 1,321m in total, was mud-rotary drilling through the sand cover.

All holes were sampled at 1m intervals from the start of RC drilling (i.e. base of mud rotary) with a total of 5,721 samples delivered to the ALS laboratory in Perth for geochemical assay.

All results have now been received by the Company with the exception of one batch of 321 samples, covering parts of holes MTRC021 and MTRC022, due to one sample being identified as possibly fibrous and delaying processing. Full results for holes MTRC021 and MTRC022 will be reported to shareholders once received.

HIGH MGO ADCUMULATE DUNITE

Assay results for MTRC006 averaged 47.4% MgO and 0.30% Al2O3 portion of the hole, whilst MTRC007 averaged 48.4% MgO and 0.24% Al2O3 (volatile free) over 239m of ultramafic and MTRC008 average 47.5% MgO and 0.19% Al2O3 (volatile free) over 237m of ultramafic. Using Al2O3 as a proxy for interstitial material and MgO as a proxy for temperature, geochemical characterisation shows the host rock to be nearly entirely high-temperature, extreme adcumulate dunite with Al2O3 generally less than 0.5% and MgO greater than 40%.

This observation of extensive intersections of high MgO extreme adcumulate dunite within the Complex, starting essentially immediately under the sand cover, has positive implications for the targeting of large volume, low grade Type 2 Mt-Keith style disseminated nickel sulphide deposits within the Mulga Tank Complex.

NICKEL SULPHIDE MINERALISATION

Broad intersections of visible disseminated nickel sulphide mineralisation have frequently been observed in the Company’s diamond core drilling and ~390m of disseminated sulphide was observed down hole MTRC009 ASX, RC Drilling Expansion and Drilling for Equity, 17 October 2023 ). However, this style of mineralisation is generally harder to see in RC drill chips.

In the absence of magmatic sulphide processes nickel is incorporated into olivine during crystallisation and essentially trapped within the dunite host rock. Whereas, in “live” sulphur saturated mineral systems the nickel will partition into potentially “recoverable” nickel sulphide form. The Company uses a number of elements, such as Cu and PGE’s (Pt and Pd), that have high affinity for sulphide (chalcophile), in combination with S (and the S:Ni ratio) as geochemical indicators to confirm the presence of active magmatic sulphide processes and the geochemical signature of nickel sulphide mineralisation.

DISCUSSION

lateral continuity of the shallow, uppermost zone of disseminated nickel sulphide mineralisation observed in the Company’s diamond holes MTD012, MTD022, MTD023, MTD026, MTD027 and MTD028 (Figure 1). The results from this RC drilling will offer a step change in the understanding of the geology and geochemistry of the Complex and its potential to host a significant disseminated nickel sulphide deposit.

The results from these three holes (and 17 previously announced holes) are very positive and demonstrate the continuity of this uppermost zone of shallow mineralisation, with numerous broad intervals of interpreted nickel sulphide mineralisation identified in all the holes. Around 40-70% of the samples from 19 of the 20 holes received to date show the geochemical signature of nickel sulphide mineralisation with elevated Ni and S, in combination with highly anomalous chalcophile elements Cu and PGE.

The Company believes the central area of the main body of the Mulga Tank Complex could host globally significant quantities of disseminated Mt Keith-style nickel sulphide mineralisation which could be amenable to large scale, open-pit mining operation.

These latest holes show further intersections of around 1% Ni or better:

MTRC006 1m at 1.19% Ni, 424ppm Co, 234ppm Cu, 21ppb Pt+Pd from 277m 1m at 0.96% Ni, 368ppm Co, 68ppm Cu, 41ppb Pt+Pd from 289m MTRC007 2m at 1.05% Ni, 394ppm Co, 583ppm Cu, 27ppb Pt+Pd from 196m 1m at 1.58% Ni, 574ppm Co, 708ppm Cu, 39ppb Pt+Pd from 197m

Holes MTRC006 and MTRC007 are located on the southern edge of the central-eastern part of the Complex, in an area where results from previously announced holes have identified richer zones of mineralisation (Figure 8). These results highlight that mineralisation tested by the RC drilling is certainly open to the south of the initial area targeted and currently remains unconstrained. The Company intends to follow-up with further drilling around this area in early 2024, aimed at extending this zone.

MULGA TANK PROJECT

JORC CODE, 2012 EDITION - TABLE 1 SECTION 1: SAMPLING TECHNIQUES AND DATA

Criteria	JORC Code explanation	Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specifc 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 (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fre 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 (eg submarine nodules) may warrant disclosure of detailed information.	• Reverse circulation (RC) drilling was completed using standard industry best practice • Individual 1m samples were collected directly from the rig sampling system. Samples were crushed and pulverised to produce a sub- sample for analysis by either multi-element ICP-AES (ME-ICP61 and ME-ICP41), precious metals fre assay (Au-AA25 or PGM-ICP23) and loss on ignition at 1,000°C (ME-GRA05)
Drilling techniques	• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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 percussion drilling rig with a 5.25inch face sampling bit
Drill sample recovery	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise 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 fne/ coarse material.	• Standard drilling techniques using “best practice” to maximise sample recovery • Information not available to assess relationship between sample recovery and grade

Criteria	JORC Code explanation	Commentary
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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged.	• Drill holes geologically logged on a metre basis • Logging is to a level of detail suffcient to support a Mineral Resource estimation, though further information would be required • Logging is qualitative in nature and recorded lithology, mineralogy, mineralisation, weathering, colour, and other features of the samples. Chip trays were photographed in both dry and wet form • Drillhole was logged in full, apart from rock rolled pre-collar intervals
Sub-sampling techniques and sample preparation	• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffed, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for feld duplicate/ second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled.	• Individual 1m samples were collected directly from the rig sampling system. Samples were crushed and pulverised to produce a sub- sample for analysis by either multi-element ICP-AES (ME-ICP61 and ME-ICP41), precious metals fre assay (Au-AA25 or PGM-ICP23) and loss on ignition at 1,000°C (ME-GRA05) • Majority of samples were dry however some ground water was encountered and some samples were taken wet • Industry standard sample preparation techniques were undertaken and considered appropriate for the sample type and material sampled • The sample size is considered appropriate to the grain size of the material being sampled

Geology	• Deposit type, geological setting and style of mineralisation.	• The geology of the project area is dominated by the irregular shaped Mulga Tank serpentinised metadunite intrusive body measuring ~5km x 5km, hosted within metasediments, mafc to felsic schists and foliated metagranite of the northwest trending Archean Minigwal Greenstone Belt • Previous drilling intersected disseminated and narrow zones of massive nickel-copper sulphide mineralisation within the dunite intrusion • The intrusion is concealed under variable thicknesses of cover (up to 70 m in places) with the interpretation of the bedrock geology based largely on aeromagnetic data and limited drilling
Drill hole information	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth hole length. • If the exclusion of this information is justifed on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	• A listing of the drill hole information material to the understanding of the exploration results provided in the body of this announcement • The use of any data is recommended for indicative purposes only in terms of potential Ni-Cu-PGE mineralisation and for developing exploration targets
Data aggregation methods	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	• No metal equivalent values have been quoted • Results where stated have been normalised to a volatile free sample based on the LOI at 1,000°C results using the formula M(VF) = M / (100%-LOI%)
Relationship between mineralisation widths and intercept lengths	• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).	• The drillhole was oriented to intersect perpendicular to the mineralisation or stratigraphy • The relationship of the downhole length to the true width is not known
Diagrams	• Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any signifcant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	• Appropriate maps, photos and tabulations are presented in the body of the announcement

Criteria	JORC Code explanation	Commentary
Balanced reporting	• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	• Reporting of signifcant intersections in Table 1 • Reporting of majority of all sample results on charts within the document
Other substantive exploration data	• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	• Not applicable
Further work	• The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	• Future exploration planned includes further drill testing of targets identifed • Exploration is at an early stage and future drilling areas will depend on interpretation of results
