For full details of the Minyari Project Mineral Resources Estimate, please refer to ASX announcement dated 2 April 2026, “Minyari Project Resource Grows to 3.6 Moz Gold Equivalent ”. 3. The Minyari Dome MRE has been reported within optimised open pit shells at a cut -off grade of 0.3 g/t gold and within optimised (MSO) underground stopes with a Net Smelter Return (NSR) ≥ A$110, using metal prices of US$5,000/oz gold, US$65 silver and AUD/USD of 0.65 and cost and revenue assumptions. 4. The satellite deposits Tim’s Dome, Chicken Ranch and RPS MREs have been reported at cut -off grades above 0.3 g/t gold which assumes open pit mining. 5.

A gold equivalent grade (Aueq) has been calculated from individual gold, copper, silver and cobalt grades. This equivalent grade has been calculated and decl ared in accordance with Clause 50 of the JORC Code (2012) that it is the Company’s opinion that all metals included in this m etal equivalent calculation have reasonable potential to be recovered and sold, using the following parameters: The m etal prices used for the calculation are as follows: − US$ 2,030 per oz gold − US$ 4.06 per lb copper − US$ 24.50 per oz silver − US$ 49,701 per tonne cobalt An e xchange rate (A$:US$) of 0.7000 was assumed. Metallurgical re coveries for by-product metals, based upon Antipa test-work in 2017 and 2018, are assumed as follows: − Gold = 88.0% Copper = 85.0%, Silver = 85%, Cobalt = 68% The g old equivalent formula, based upon the above commodity prices, exchange rate and recoveries, is thus: Aueq = (Au g/t) + (Ag g/t * 0.012) + (Cu % * 1.32) + (Co % * 5.88) INVESTOR PRESENTATION | 43 Competent Persons Statement – Exploration Results The information in this document that relates to Exploration Results is based on and fairly represents information and supporting documentation compiled by Mr Roger Mason, a Competent Person who is a Member of The Australasian Institute of Mining and Metallurgy.
