• 930,000 tonnes @ 1.73% CuEq confirmed from the Scorpion-Window open pit optimisation
• Scoping Study production target material comprises 98% Indicated Resources
• Total of 13.6Mt from the optimised open pits, a 3.2Mt increase in material

QMines Limited has reported the results of an open pit scoping level optimisation completed at the Scorpion-Window deposit within the Develin Creek project in central Queensland. The optimisation confirms a Production Target of 930,000 tonnes grading 1.21% Cu, 0.95% Zn, 0.2g/t Au and 8.1g/t Ag with a Copper Equivalent (CuEq) grade of 1.73%. The Scorpion-Window optimisation will now progress to a mine design for future inclusion in the company's revised Pre-Feasibility Study (PFS) expected in H2-2026. The total optimised open pit material across Mt Chalmers, Develin Creek and Mt Mackenzie has now grown to 13.6Mt, an uplift of 3.2Mt on the initial 10.4Mt from Mt Chalmers. The company is confident the Develin Creek project can deliver high-grade feed into the proposed Mt Chalmers processing hub, with robust metallurgical recoveries already demonstrated. The optimisation advances QMines' broader vision to become a low cost, long-life copper and gold producer in central Queensland.

With several additional deposits still to be optimised, this reinforces the scale of the regional opportunity QMines is building. The company is confident this project will evolve into a significant, long-life copper and gold operation for Central Queensland.
