September 2025 Quarterly Report 2

Westgold Managing Director and CEO Wayne Bramwell commented:

“Westgold’s underlying cash build in Q1, FY26 of $180M before growth and exploration spend, culminated in a

closing balance of $472M in cash, bullion, and liquid investments . This was an increase of $108M quarter on

quarter.

Operationally, we maintained our focus on safety and efficiency, achieving an 11% improvement in our TRIFR

and delivering group gold production of 83,937 ounces at an AISC of $2,861 per ounce. This was a solid start to

FY26, and we remain on track to FY26 guidance of 345,000 to 385,000 ounces at an AISC of $2,600 to $2,900

per ounce.

The 2025 Reserves and Resources statement released during the quarter demonstrated the success of

continued investment in growth projects and exploration, with our Mineral Resource Estimate increasing by

24% to 16.3Moz and Ore Reserves up 5% to 3.5 Moz. This growth now underpin a 10-year Ore Reserve life and

highlights the latent mineral potential that drilling can unlock from within our portfolio.

In Q1 the Company released its first three-year outlook (3YO) to the market. The 3YO is a high confidence plan

building from a FY26 production guidance mid-point of 365,000 ounces, growing organically to approximately

470,000 ounces of production by FY28. Importantly, the 3YO is conservative by design , sees our cost profile

fall and excludes multiple tangible opportunities currently being advanced to bring value forward in the outlook.

Westgold’s value proposition is to focus on organic growth to increase shareholder returns. This objective is

now underpinned by growing treasury strength, increasing Ore Reserves, four processing hubs and a pragmatic

approach to capital allocation that creates value. The declaration of a 3 cent per share final dividend for FY25

shows our commitment to shareholder returns with an upgrade to our dividend policy for FY26 and the launch

of a 5% on-market share buyback defining our approach.

Our team is focussed on optimising our larger producing assets in FY26 to maximise free cash flow. With

improving operational performance and a clear pathway defined by the 3YO, the business can now plan to

sustain safe, responsible, and profitable production into the future.”

September 2025 Quarterly Report 4

Group Production Highlights – Q1, FY26

Westgold is pleased to report Q1, FY26 Group gold production of 83,937oz (Q4 FY25: 88,022oz). The Murchison

produced 53,140oz (Q4 FY25: 54,811oz) and the Southern Goldfields produced 30,797oz (Q4 FY25: 33,211oz).

Q1, FY26 production was marginally lower than Q4, FY25 as expected due to scheduled process plant

shutdowns across the group . This is consistent with the e ectations set out in Westgold’s FY Guidance,

which shows group production output weighted towards the second half of FY26.

All-In Sustaining Cost ( AISC) for Q1, FY26 was $240M (Q4 FY25: $ 237M), and on a per ounce basis was

$2,861/oz (Q4 FY25: $2,688/oz). The higher quarter -on-quarter costs were primarily due to the early

commencement of third-party ore delivery (from the gold price linked Ore Purchase Agreement (OPA) with New

Murchison Gold), planned maintenance costs and lower Group production. Excluding gold production from

ore purchased under the OPA, Group AISC was $2,792/oz.

Westgold maintains its production and cost guidance for FY26 of 345 – 385koz at $2,600 – $2,900/oz.

Figure 2: Westgold Quarterly Production (oz), Achieved Gold Price and AISC ($/oz)

The Company sold 94,913oz of gold for the quarter achieving a record price of $5,296/oz, generating $503M in

revenue. With Westgold hedge free , operations generated $205M of mine operating cashflow s with the

achieved gold price $2,435/oz over AISC.

Total non-sustaining capital expenditure during Q1 FY26 of $60M (Q4 FY25: $39M) includes $39M of investment

in growth projects (Bluebird-South Junction and Great Fingall development) and $21M in plant and equipment

(processing facilities, ventilation, water, power and paste infrastructure across the Group).

Investment in exploration and resource development of $12M (Q4 FY25: $9M) for the quarter continued

focusing on Bluebird-South Junction and Starlight in the Murchison, and the Fletcher Zone at Beta Hunt in the

Southern Goldfields. Westgold remains on track to achieve the FY26 exploration guidance of $50M.

September 2025 Quarterly Report 5

The net mine cash inflow for Q1 FY26 was $133M (refer Table 1 under Group Performance Metrics).

FY26 guidance and 3 year outlook

Westgold issued its FY26 guidance in August 2025 , signalling an uplift over the prior year in group mine and

milling out uts. The om any’s outloo is su orted by ongoing investments in ey processing and mining

assets and more consistent operational performance, positioning Westgold for continued value creation.

For FY26, Westgold forecasts gold production in the range of 345,000 oz to 385,000oz at an AISC of $2,600 to

$2,900 per ounce, reflecting a substantial production improvement over FY25. The om any’s guidance also

includes indicative AISC for purchased ore . Planned non -sustaining capital expenditure totals $27 0M,

predominantly directed toward major growth projects and infrastructure upgrades . The exploration and

resource definition budget is set at A$50 M, representing a balanced investment in exploration, targeting

significant drilling activity across core regions.

Building on the FY26 guidance, Westgold released a detailed three-year outlook (3YO) on 1 October 2025 that

presents a high-confidence, e ecutable lan to increase the Grou ’s annual gold roduction to a ro imately

470,000oz per annum by FY28, while reducing AISC to around $2,500 /oz from FY27 onwards. This organic

growth plan is predicated u on Westgold’s existing portfolio of operating assets, 2025 Ore Reserves (56 Mt at

1.93g/t for 3.5 Moz of gold), and the four processing hubs with a combined current processing capacity of

approximately 6Mtpa.

Importantly, the 3YO excludes tangible opportunities that, if realised represent substantial upside to the

plan. These opportunities are being actively advanced to bring value forward into the 3YO.

September 2025 Quarterly Report 7

Q4 FY25 Group Performance Overview

Westgold mined a total of 1,225kt at 2.2g/t Au (Q4 FY25: 1,264kt at 2.3g/t Au) slightly down quarter on quarter

as expected, driven by level access and paste establishment at Bluebird South Junction mine at Meekatharra.

Westgold processed 1,355 kt (Q4 FY25: 1,408kt) of ore in total at an average grade of 2.1g/t Au (Q4 FY25: 2.1g/t

Au), producing 83,937oz of gold ( Q4 FY25: 88,022oz). Group AISC in Q1 FY26 was $240M, marginally higher

than the previous quarter (Q4 FY25: $237M).

MURCHISON

The Murchison hubs produced 53,140oz of gold (Q4 FY25: 54,811oz). Quarterly production declined slightly as

anticipated due to planned processing maintenance shutdowns at the three processing hubs and lower grades

mined at Fortnum.

The quarter-on-quarter reduction in ore mined was driven primarily by schedule constraints at Bluebird-South

Junction as the mine transitioned to paste fill. Encouragingly, the first paste pour was completed in Q1 ahead

of target, placing the Meekatharra Hub in a strong position to lift production as forecast over the year. The lower

quarter-on-quarter mining rate from Bluebird-South Junction was partly offset by the early delivery of ore under

the OPA with New Murchison Gold which contributed 2,601oz.

Total AISC of $163M (Q4 FY25: $138M) was higher than the prior quarter, mainly due to the commencement of

the gold price linked OPA and planned maintenance across the three processing hubs.

AISC per ounce of $3,061/oz (Q4 FY25: $2,503/oz) increased due to the higher total AISC and lower quarterly

production. Excluding the OPA, the Murchison AISC per ounce was $2,960/oz.

Total Non-Sustaining Capital Expenditure of $38M, includes Growth Capital ($30M) and Plant and Equipment

($8M) across the Murchison. Growth Capital mainly related to the continuation of Great Fingall development

and expansions to the Bluebird-South Junction underground mine.

SOUTHERN GOLDFIELDS

The Southern Goldfields hub produced 30,797oz of gold in Q1 FY26 (Q4 FY25: 33,211oz). Higginsville

throughput was in line with expectations . Production was lower quarter on quarter due to the timing of an

additional tolling parcel in Q4 FY25 at Lakewood. Beta Hunt mining output was in line with expectations and

steady quarter on quarter. Beta Hunt mining rates are expected to lift from late Q2, FY26 onwards as new

ventilation and pumping infrastructure removes constraints in the mine.

The total AISC in the Southern Operations decreased quarter on quarter (Q1 FY26 AISC: $77M vs Q4 FY25 AISC:

$99M). On a per ounce basis, AISC was lower at $2,516/oz in Q1 FY26 (Q4 FY25: $2,992/oz). This is

predominantly due to the combined impact of a 61kt stockpile build and the non-cash adjustment to stockpile

values of the Southern Goldfields following the finalisation of the purchase price allocation for the Karora

transaction.

Total Non-Sustaining Capital Expenditure of $22M, includes Growth Capital ($9M) and Plant and Equipment

($13M) across the Southern Goldfields Operations mainly relating to water management, primary ventilation

and underground infrastructure at the Beta Hunt mine.
