Copper Discovery at Mt Chalmers

• New copper discovery 180m beyond existing resource
• Mineralisation exhibits characteristics of Mt Chalmers copper-gold system
• Potential for additional massive sulphide lenses
• Follow-up drilling underway, assays expected in late October

Qmines Ltd announced a significant copper discovery at its Mt Chalmers project, with drillhole 26MCDD052 intersecting an 11-meter zone of visually identified copper sulphides, including semi-massive chalcopyrite-pyrite mineralisation, approximately 180 meters beyond the existing resource. The mineralised intercept exhibits characteristics consistent with the Mt Chalmers copper-gold system, indicating potential for significant resource growth. The discovery could represent a northern extension of the Mt Chalmers main lode, a separate NNE-trending mineralised zone, or mineralisation associated with Botos. Follow-up drilling is underway to test the zone's orientation, true width, and continuity, with laboratory assays expected in late October 2026.

Qmines is optimistic about the potential for significant resource growth at Mt Chalmers, with the new discovery providing a basis for further exploration in the area.
