• Life-of-mine forecast gold production increased by 82,000oz to 1.22Moz
• Base Case NPV5 post-tax cashflow increased by A$75 million to A$1.028B with an IRR of 52.4%
• Lower AISC of A$2,157/oz over first four years and A$2,252/oz life-of-mine

Ausgold Ltd has completed an Updated Definitive Feasibility Study (DFS Update) for its 100%-owned Katanning Gold Project (KGP) in Western Australia. The DFS Update incorporates a re-estimation of the June 2025 Definitive Feasibility Study mine plan to reflect project enhancements stemming from a transformative land acquisition deal. The updated DFS demonstrates exceptionally robust financial returns over a +10-year mine life, with average annual gold production of 143kozpa in the first four years supporting strong early cashflows and rapid capital payback. The Base Case NPV5 post-tax cashflow increased by A$75 million to A$1.028 billion (US$0.67 billion) with an IRR of 52.4% at a A$4,300/oz (US$2,795/oz) gold price. At the current spot gold price of approximately A$6,400/oz (US$4,300/oz), the NPV5 post-tax cashflow is A$2.30 billion (US$1.55 billion) with an IRR of 92%. The increased 1.33Moz Ore Reserve, of which 83% is in the Proved category, underpins the life-of-mine production of 1.22Moz at an average gold recovery of 90.4%. The project location, close to the regional hub of Katanning, provides excellent existing roads and infrastructure and easy access to major regional centers.

The DFS Update forecasts average annual gold production of 143kozpa in the first four years of the +10-year mine life, with a life-of-mine All-In Sustaining Cost of A$2,252/oz (US$1,464/oz).

Ausgold is progressing pre-development activities at pace, including front-end engineering and design, tendering of key contracts, and finalizing permitting for the Katanning Gold Project, with the aim of reaching a final investment decision in mid-2026.
