QMines Says Open Pit Optimization at Queensland Gold-Silver Project Delivers Production Target Estimate

MT Newswires Live

Jul 22, 2025

QMines (ASX:QML) said open pit optimization results for its Mt. Mackenzie gold-silver project in Queensland delivered a production target estimate of 800,000 tonnes of oxide material at 1.3 grams per tonne grade of gold and 7.7 g/t grade of silver and 1.5 million tonnes of sulfide material at 1.38g/t grade of gold and 9.5 g/t grade of silver, according to a Tuesday Australian bourse filing.

The production target estimate consists of 90% indicated and 10% inferred resources.

This demonstrates that Mt. Mackenzie can be economically mined via open pit mining and hauled to the planned Mt. Chalmers process plant, and based on these positive results, Mt. Mackenzie will be integrated into the Mt. Chalmers updated prefeasibility study due for release in the first half of 2026.
