Westgold Resources Limited (ASX:WGX) has released its updated Mineral Resource Estimate and Ore Reserve Statement as of 30 June 2025, confirming significant growth across its gold portfolio in Western Australia.

As of the reporting date, the company’s total Mineral Resource Estimate stood at 231 million tonnes at 2.18 grams per tonne (g/t) gold for 16.3 million ounces (Moz). This represents a 24% increase compared to the prior year, reflecting an additional 3.1 Moz added post mining depletion. The total Ore Reserves were reported at 56 million tonnes at 1.93 g/t Au for 3.5 Moz, marking a 5% increase year on year.

Resource Expansion Across Key Assets

Westgold’s exploration and resource definition drilling campaign during FY25 underpinned the growth, with AUD 43 million invested, following AUD 25 million in FY24. The expansion was driven by developments across the company’s operating mines and broader portfolio, with the Murchison and Southern Goldfields regions delivering major contributions.

At the Murchison operations, Mineral Resources increased by 990,000 ounces post depletion, led by growth at Bluebird – South Junction and Starlight. The Bluebird – South Junction Mineral Resource rose to 1.3 Moz, representing a 35% increase year on year, while Starlight’s Mineral Resource advanced to 866,000 ounces, a 46% increase. Ore Reserves also grew substantially, with Bluebird – South Junction up 90% to 528,000 ounces and Starlight up 94% to 250,000 ounces.

At the Southern Goldfields operations, a maiden Stage 1 Fletcher Zone Mineral Resource Estimate was declared at Beta Hunt, totaling 31 Mt at 2.3 g/t Au for 2.3 Moz of gold. This contributed significantly to the overall increase, with the region’s Mineral Resources up by 2 Moz, or 72%, year on year post depletion.

Reserve Life and Future Exploration

Westgold now reports an estimated Reserve life of approximately 10 years, supported by a milling capacity of 5.7 million tonnes per annum across its three processing hubs: Bluebird, Tuckabianna, and Fortnum in the Murchison, and Higginsville in the Southern Goldfields.

The company confirmed that 19 drill rigs are currently active, both on surface and underground, across its 3,200 km² portfolio. In FY26, Westgold plans to allocate AUD 50 million towards exploration and resource development, building on the progress made in FY25.
