June 2026 Quarterly Report 2

Westgold Managing Director and CEO Wayne Bramwell commented:

“FY26 was a defining year for Westgold and showed our strategy is delivering results.

Over the past two years, we have simplified our portfolio, focused on our highest return assets and prudently allocated

capital on key projects and infrastructure that enables future growth. In FY26, this strategy delivered record annual

production of 387,354oz, above our guidance range, achieved our cost guidance, and placed Westgold in the strongest

treasury position in its history.

Improving operational delivery generated an underlying cash build of $233M for the quarter, with Westgold closing FY26

with $939M in cash, bullion and liquid investments. We remain debt free, unhedged and with the financial strength to

fund both organic growth, and ongoing return of capital to our shareholders.

During the quarter, we invested $142M in growth, optimisation and infrastructure projects across the business. This

included $79M of planned investment in key growth projects including the Bluebird-South Junction and Great Fingall

mine developments and the early commencement of the Murchison Open Pit Programme which was brought forward

from FY27. We also invested $64M in plant and equipment including the purchase of the Westgold Village, formerly

known as the Bluebush Accommodation Village in Kambalda.

Corporately we have been active, completing the Valiant Gold (ASX: VAL) IPO in March and the divestment of our

remaining non-core assets during Q4. These initiatives streamline our portfolio and immediately unlock significant

value for our shareholders.

On a cost basis, Westgold’s full year cost performance was within our guidance and reflects greater scale, improving

asset utilisation and more disciplined operational and commercial execution. In FY27 cost control remains key, with

our team focused on lifting mill feed grade, mine productivity and processing efficiency to offset potential cost inflation

across the sector.

Westgold enters FY27 with a committed team, increasing operational momentum, a robust balance sheet and

confidence in our long-term strategy. These factors enhance the resilience of our business and with our four processing

hubs being optimised, cornerstone mines ramping up and our internal financial capacity to support organic growth,

Westgold is well placed to continue to deliver sustainable returns to our shareholders.”

June 2026 Quarterly Report 3

Executive Summary

Cash Position as of 30 June 2026

Westgold closed Q4 FY26 with cash, bullion and liquid investments of $939M – representing a quarter-on-quarter build

of $83M.

Underlying cash build for Q4 FY26 was $233M - before share buy backs ($22M), growth and exploration spend (invested

$142M on non-sustaining capital and $11M on exploration), and one- off cash inflows (proceeds from asset divestment

totalled $25M).

June 2026 Quarterly Report 4

Group Highlights – Q4, FY26

In Q4 FY26, Westgold processed 1,468 kt (Q3 FY26: 1,481kt) of ore at an average grade of 2.3g/t Au (Q3 FY26: 2.1g/t

Au), producing 98,854oz of gold (Q3 FY26: 93,145oz). The higher production was driven from the Murchison business

with increasing contributions from higher grade ore from Starlight, the expanding Bluebird-South Junction underground

mine, improvement in the Cue operations and third party purchased ore processed at the Meekatharra hub.

During the quarter, Westgold mined 1,334kt at 2.1g/t Au (Q3 FY26: 1,148kt at 2.2g/t Au). Total tonnes mined increased

quarter on quarter due to improving mining rates at Bluebird-South Junction, Big Bell, Great Fingall and Beta Hunt.

On a full year basis, Westgold produced 387,354oz of gold for FY26, achieving record annual production for the

Company and exceeding the top end of our FY26 production guidance of 345,000 – 385,000oz. 2

All-In Sustaining Cost (AISC) for Q4 FY26 was $230M (Q3 FY26: $231M), and on a per ounce basis was $2,802/oz (Q3

FY26: $2,931/oz). The reduction in AISC/oz was driven primarily by the higher production quarter on quarter.

FY26 AISC was $2,841/oz - delivering our FY26 cost guidance range of $2,600 – $2,900/oz.2

Increases in the price of diesel added $12M to Westgold’s cost base in Q4 FY26, offset by a reduction in royalty

payments due to the softening of the gold price compared to the prior quarter.

Importantly, Westgold has not experienced any diesel supply disruptions. The Company maintains long-term supply

agreements with a global major diesel producer, providing security of supply across its operations. Westgold retains

contingency plans to manage potential supply disruptions due to geopolitical developments in the Middle East,

ensuring operational continuity and the protection of shareholder value.

Westgold’s current 3-Year Outlook3 (3YO) outlines a clear strategy going forward to optimise value from our core

assets. Lower grade stockpile feed is progressively being replaced with higher grade sources across the portfolio, with

Westgold actively accelerating organic opportunities (such as the Murchison Open Pit Programme) that can bring value

forward across the 3YO.

Westgold will provide its full year FY26 Financial Results, a dividend update, and FY27 Guidance in August 2026. With

FY26 now complete, the Company will also provide an updated 3 Year Outlook in August that will incorporate FY29.

June 2026 Quarterly Report 5

*Q1 and Q2 FY26 AISC adjusted post Half-Year Financial Report for the period ended 31 December 2025

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

In Q4 FY26, the Company sold 110,345oz of gold achieving a price of $6,391/oz , generating $705M in revenue. With

Westgold hedge free, operations generated $313M of mine operating cashflows and a strong AISC margin of $3,589/oz.

Total non-sustaining capital expenditure during Q4 FY26 of $142M (Q3 FY26: $81M) includes $79M of planned

investment in growth projects (Bluebird-South Junction and Great Fingall development, and the early commencement

of the Murchison Open Pit Programme brought forward from FY27) and $64M in plant and equipment (processing

facilities, ventilation, water, and camp infrastructure across the Group, and purchase of the Westgold Village, formerly

known as the Bluebush Accommodation Village in Kambalda).

Total non-sustaining capital expenditure for FY26 was $341M, above FY26 guidance of $270M2. The increase primarily

reflects the deliberate acceleration of several high-return growth and optimisation initiatives planned for FY27,

including bringing forward capital elements of the Murchison Open Pit Programme and investment in infrastructure in

FY26 to support future production growth.

Investment in exploration and resource development for the quarter was $11M (Q3 FY26: $13M). For FY26, exploration

and resource development investment was $42M, below the FY26 exploration guidance of $50M2. The variance

primarily reflects the timing of approvals and access requirements for planned drilling programs, with expenditure

deferred into FY27.

Westgold expects exploration investment to increase in FY27. This is a deliberate decision as increasing our drilling

budgets in resource development and exploration can build value and reduce execution risk of the Company's

extensive pipeline of organic growth opportunities.

The net mine cash inflow for Q4 FY26 was $159M (refer Table 1 under Group Performance Metrics).

June 2026 Quarterly Report 8

Q4 FY26 Group Performance Overview

MURCHISON

Westgold’s Murchison operations delivered a stronger quarter-on-quarter performance, producing 74,096oz of gold in

Q4 FY26 (Q3 FY26: 64,132oz). The improvement was driven by increased production from the Meekatharra Hub

following the continued ramp-up of Bluebird-South Junction, together with stronger contributions from Big Bell, Great

Fingall, Starlight and third party purchased ore.

At the Meekatharra Hub, Bluebird-South Junction continues to demonstrate the benefits of the updated mine design

and operating methodology, delivering higher mining rates (including hitting a 1Mtpa run rate in June), increased ore

supply and improved production outcomes quarter-on-quarter. The operation continues to build momentum as one of

Westgold's key growth assets, with mining performance tracking in line with the planned expansion profile.

Development and mining productivity remained strong during the period, underpinning confidence in Bluebird-South

Junction's ability to deliver sustained mining rates through FY27.

Additional quarter on quarter production growth was delivered from Big Bell, Great Fingall and Starlight. Following

completion of the Big Bell ventilation upgrade in Q3, improved airflow increased access to mining areas and supported

record ore outputs. Great Fingall continued its progressive ramp-up as deeper virgin stopes were opened, while

Starlight benefited from improved grade performance from the Nightfall stopes.

These Murchison assets provided a meaningful contribution to Westgold’s stronger quarter-on-quarter performance

and reflect the operational flexibility within the Murchison business unit.

Also at the Meekatharra Hub, the New Murchison OPA delivered 17koz at 3.1g/t in Q4 FY26, up from 14koz at 3.1g/t in

Q3 FY26. The OPA material provided more oxide material than expected, facilitating continued higher than planned

processing rates through Westgold’s Meekatharra processing hub.

Total AISC of $148M (Q3 FY26: $128M) was higher than the prior quarter due to improved milling performance drawing

down on surface stockpiles built during the prior quarter.

AISC per ounce of $2,567/oz (Q3 FY26: $2,584/oz) was in line with the prior quarter.

Total Non-Sustaining Capital Expenditure of $94M, includes Growth Capital ($65M) and plant and equipment ($29M)

across the Murchison. Growth capital was higher than the prior quarter as a result of increased development costs at

Great Fingall, longer-dated extensional drilling at Bluebird-South Junction and the deliberate decision to commence

the Murchison Open Pit Programme earlier than originally planned (in late FY26), bringing value forward in the 3YO.

SOUTHERN GOLDFIELDS

The Southern Goldfields produced 24,758oz of gold in Q4 FY26 and as expected, was lower than the prior quarter (Q3

FY26: 29,013oz). The lower quarter-on-quarter production outcome was primarily driven by reduced tonnes processed,

reflecting the scheduled deferral of a 50kt toll treatment parcel at the Lakewood processing facility (previously flagged

in Q3 FY26). Toll treatment at Lakewood is scheduled to recommence in Q1 FY27.

The total AISC in the Southern Goldfields decreased quarter on quarter (Q4 FY26 AISC: $82M vs Q3 FY26 AISC: $103M).

On a per ounce basis, AISC was lower at $3,331/oz in Q4 FY26 (Q3 FY26: $3,546/oz). This is predominantly due to lower

processing maintenance spend with no major planned shutdown and no toll treating at Lakewood.

Total Non-Sustaining Capital Expenditure of $48M in Q4 FY26 - includes Growth Capital ($14M) and plant and

equipment ($35M) across the Southern Goldfields Operations mainly relating to the purchase of Westgold Village

($22M), primary ventilation, extensional drilling and power distribution equipment at the Beta Hunt mine, and tailings

storage facilities at Higginsville.
