The organic potential of this portfolio is immense. Westgold is well funded, systematic and focussed on expanding the assets that can deliver higher quality mine outputs, reduce our cost base and enhance our production profile."

Overview

In Q3 FY25, Westgold invested $11M in exploration and resource definition across its portfolio. The Company drilled a total of 82,898m, as summarised by the table below.

Exceptional intercepts returned this quarter from drilling activities are listed below:

Westgold had 16 underground drill rigs and 1 surface drill rig operating at the end of the quarter. The surface drill was operating at Peak Hill and the underground rigs were operating at Starlight (3), Bluebird (2), Great Fingall (3), Beta Hunt (7) and Two Boys (1).

Murchison

Westgold drilled 50,725m in the Murchison in Q3 FY25.

Resource Development Activities

Starlight (Fortnum)

At Fortnum, the focus on defining the high-grade Nightfall Zone ahead of mining activities continued. A large volume of high-grade results in areas set to be mined in CY25 have been assessed, with many showing grades and widths exceeding those modelled in the current mine plan.

Some of the more exceptional result returned this quarter include:

• 9.47m at 25.56g/t Au from 68.00m in NF1120GC89;

• 15.47m at 23.53g/t Au from 82.00m in NF1120GC100; and

• 25.00m at 17.66g/t Au from 169.00m in NF1090GC14.

The Starlight underground mine continues to outperform expectations, and the latest quarter of drilling results suggest this trend will continue.

In December 2024, Westgold announced the results of a Scoping Study on the Fortnum Expansion Project (FXP) which detailed the viability of an expanded Fortnum Gold Operation at an increased milling rate of 1.5 Mtpa over a ten year life¹. The subsequent Pre-Feasibility study has progressed through the detailed pit design and scheduling stage which now contemplates open pit mining progressing as part of a larger, Murchison-wide open pit mining campaign.

Drilling programs to bring this phase of the work to a decision point are currently being designed, and the necessary permitting and infrastructure works are being progressed.

A drill platform in the upper levels of the Starlight underground mine is also in the planning stage. This platform is being designed to enable increased production out of the existing Starlight underground mine and de-risking the deeper portion of the Starlight open pit contemplated by the FXP.

It is anticipated that development of this platform will commerce in Q4 FY25.

Bluebird-South Junction (Meekatharra)

Following on from the large increases in Mineral Resources² and subsequent increase in Ore Reserves³ for Bluebird - South Junction during Q2 FY25, Westgold has focussed ongoing drilling works to support the execution of the greater Bluebird - South Junction mine plan.

Drilling in Q3 FY25 was directed towards providing increased definition ahead of the mining front. Better results from this program include:

• 8.11m at 12.66 g/t Au from 166.00m in 24BLDD203A;

• 6.72m at 8.30 g/t Au from 163.00m in 24BLDD205; and

• 6.57m at 9.41 g/t Au from 170.00m in 24BLDD208.

Fender (Cue)

At Cue, increasing outputs from the upper levels of the Big Bell cave has allowed Westgold to focus drilling resources on the satellite Fender mine and on building geological understanding at the high-grade Great Fingall mine.

At Fender, drilling outcomes have been consistent with expectations, with results such as the following being amongst the standouts:

• 3m at 9.42g/t from 90.00m in 24FNDD0060; and 

• 15.92m at 2.07g/t from 93.00m in 24FNDD0067. 

Great Fingall (Cue)

The application of additional drilling resources at Great Fingall has allowed the testing of areas such as Sovereign Extensions, which currently lie outside of the existing mine plan. This initiative also supports the ongoing definition of the Great Fingall Reef itself.

Results such as those listed below from Sovereign and in what was a previously unrecognised lode are indicative of the upside potential at this historical +1Moz producer: § 19.45m at 2.16g/t Au from 155.00m; and

• 5.7m at 8.25g/t Au from 270.00m in 24SVDD036 at Sovereign; and 

• 0.71m at 55.50g/t Au from the collar in 24SHDD031A.

In the Great Fingall Reef, results like 3.60m at 8.13g/t Au from 176.00m in 24GFDD116 allude to the impact that Great Fingall production is likely to have on overall head grade through the Tuckabianna mill.

Cuddingwarra (Cue)

The evaluation of large-scale open pit opportunities continue at Cuddingwarra.

As part of the portfolio optimisation, initial evaluations of the district-scale resource model amalgamation were undertaken during the quarter. This first pass evaluation was compelling and encouraged Westgold to move to the next phase which will include endowment modelling of the district. This will in-turn drive another suite of pit evaluations to help Westgold determine the upper limits of potential for the project. With the completion of this work, the Company will have a clear pathway to bring the project to an Investment Decision.

Greenfields Exploration Activities

Greenfields activities in the Murchison included the completion of a major target review and prioritisation program across the ~ 1,200km² portfolio, completion of the Five Ways South Reverse Circulation (RC) drill program at Peak Hill (Fortnum), which had commenced in late Q2 FY25, and commencement of the Murphy Creek Aircore (AC) drilling program at Peak Hill (Fortnum).

Exploration Target Review and CY25 Prioritisation

Post completion of the merger with Karora Resources on 1 August 2024, which resulted in the exploration tenure portfolio increasing from ~1,200km² to ~3200km² (combined Murchison and Southern Goldfields), the expanded exploration team completed a full review of the target pipeline and agreed the top 10 targets in each of the Murchison and Southern Goldfields regions.

While this work delayed some planned drill programs, it has built confidence in the target pipeline for CY25. The resultant priority targets for the Murchison are shown in Figure 6.

Peak Hill – Five Ways South RC Program

During the quarter, the Five Ways South RC program at Peak Hill was completed with an additional 15 holes for 4,047m drilled. This program targeted potential analogous lithostructural positions south of the historic Five Ways open pit mine which produced 6.57Mt @ 3.07g/t Au for 649Koz.

Assay results for the program provided valuable insights, with two holes returning ore grade intersections including (see Appendix A for details):

• 5.00m @ 5.79g/t Au from 144.00m in hole 25PKRC013; and

• 3.00m @ 11.04g/t Au from 146.00m in hole 25PKRC015.

These results indicate potential, and a full analysis of the results is underway with a decision pending potential follow-up drill programs.

Peak Hill - Murphy Creek AC Program

The Murphy Creek drill program commenced late in the month with 28 holes for 1,899m drilled by 31 March. The program is testing identified targets along strike to the northwest of the Company's Durack deposit which currently hosts an Indicated and Inferred Resource of 2.9Mt @ 1.2g/t Au for 111Koz⁴. This potential strike extension has not previously been effectively tested due to the presence of very shallow Bryah Basin volcanic "cover".

The program is yet to be completed, and all assay results were pending at the end of the quarter.

Southern Goldfields

Westgold drilled 32,173m in the Southern Goldfields in Q3 FY25.

Resource Development activity

Beta Hunt (Kambalda)

Seven drill rigs have remained active this quarter at Beta Hunt, extending and refining the Mineral Resource base to support future production growth at the mine.

The Fletcher Stage 1 Exploration Target⁵ resource definition program is nearing completion, with the drilling of the final holes having commenced at the end of the quarter. Results have steadily returned, and the Company expects to compile an initial Mineral Resource Estimate for Fletcher Stage 1 by the end of FY25.

Notable results this quarter include:

• 45.50m at 2.23g/t Au from 746.00m in WF440DD-37AE; an

• 63.00m at 3.62g/t Au from 324.00m in WF490DD-51AE.

Significant results continue to emerge from Western Flanks, the primary source of production at Beta Hunt, illustrating the scale of the orebody and suggesting its potential for future production, including:

• 21.00m at 2.82g/t Au from 130.00m in AWSP310-02AG; and 

• 22.00m at 4.69g/t Au from 134.00m in AWSP310-04AG. 

Higginsville

At Higginsville, Westgold has quickly moved its first Southern Goldfields open pit project to the execution phase. The project reached this stage after completing resource definition, grade control works, design and evaluations, and establishing a commercial agreement with an open pit contract miner.

The open pit contractor has mobilised and first ore production from the Atreides, Harkonnen and Bridgette open pits was achieved in April 2025.

This quarter saw continued progress on developing the Higginsville Line of Lode underground targets. Planning and evaluation efforts have progressed, allowing for the determination of the mine execution sequence. Current efforts are concentrated on defining the technical work program necessary to mitigate risks associated with any investment decision.

Greenfields Exploration Activities

Greenfields exploration activities in the Southern Goldfields included the completion of a major target review and prioritisation program across the ~ 2,000km² portfolio along with receipt and review of the assay results for the Erin and Bandido RC drill programs completed in Q2 FY25, ongoing geophysical and geochemical exploration programs, and the commencement of Aboriginal Heritage surveys over priority drill targets.

Exploration Target Review and CY25 Prioritisation 

As described in the Murchison section above, the same target review and prioritisation exercise was completed in the Southern Goldfields during the quarter with the resultant priority targets shown on Figure 11.

Higginsville - Erin RC Drill Program Results 

The final assay results for the Erin RC Drill Program completed at Higginsville in Q2 FY25 were received during the quarter with analysis and interpretation completed. A total of 15 holes returned assays of interest, with the best intersections being (see Appendix A for details):

• 9.00m @ 5.21g/t Au from 93.00m in hole KXRC0467;

• 2.00m @ 18.70g/t Au from 87.00m in hole KXRC0467;

• 10.00m @ 1.67g/t Au from 102m in hole KXRC0461; and

• 1.00m @ 14.90g/t Au from 62.00m in hole KXRC0467.

The best results were related to mineralised structures and veining proximal to lithological contacts between gabbro/dolerite/basalt/porphyry units. These units were observed to be the most brittle of the units encountered and most susceptible to dilation and thus are more favourable for mineralised fluids. Gold mineralisation is very nuggety making interpretation difficult, but further work is underway, particularly around the potential of an identified porphyry unit that has potential to the north.

Higginsville - Bandido RC Drill Program Results

The final assay results for the Bandido RC program completed at Higginsville in Q2 FY25 were received during the quarter, with analysis and interpretation completed. Assay results for the program did not warrant further investigation, and so no further work is currently planned for this target.

Beta Hunt – Mason Target

Since acquiring Beta Hunt, the Company has been compiling and reinterpreting the available extensive historical drilling information with the aim of building a new comprehensive 3D geological model of the entire Beta Hunt sub-lease area⁶. While this work is well advanced, a significant number of historical Western Mining Corporation (WMC) nickel drill holes that have never been assayed for gold were identified. These drill holes represent an outstanding exploration data source that Westgold has commenced re-logging and assaying for gold in key areas within the sub-lease boundary to allow completion of the new 3D model.

During the 3D model building process, the significance of the Mason Target was highlighted and is now interpreted to be the southern extension of the Fletcher Zone, south of the Alpha Island Fault (AIF) (Figure 12). This is consistent with the known movement on this important fault where the Larkin Zone is interpreted to be the southern continuation of Western Flanks.

The Mason Target, which is interpreted to be ~1.8km long, has been intersected by a modest number of historical drill holes with most of these in a fan at the northern end of the zone, proximal to the AIF. The identified historical drill holes at Mason have returned some outstanding gold intersections which are shown on Figure 12 and detailed in the ASX Release of 18 February.

First pass drill testing of the Mason target is scheduled for Q1 FY26 and will comprise 9 diamond drill holes for ~6,000m.

This report contains references to estimates of Mineral Resources and Ore Reserves. The estimation of Mineral Resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral Resources that are not Ore Reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral Resource estimates may require re-estimation based on, among other things: (i) fluctuations in the price of gold; (ii) results of drilling; (iii) results of metallurgical testing, process and other studies; (iv) changes to proposed mine plans; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses.
