Extending Known Zones

Recent intersections have revealed strong grade continuity, supporting the geological model for Sulphide City. The drilling has identified multiple mineralised zones within single holes, showcasing the potential scale of the deposit.

The company’s approach combines both infill and step-out drilling to target deeper extensions and refine the understanding of semi-massive and massive sulphide formations. By using diamond drilling tails to reach targeted depths, QMines is improving confidence in its resource estimates and planning for future development phases.

Integration into Long-Term Plans

Develin Creek is viewed as a cornerstone asset within QMines’ broader strategy. The company aims to integrate output from Sulphide City with material from the Mt Chalmers and Mt Mackenzie projects, creating a steady supply for a large-scale copper-gold-zinc operation in Central Queensland.

Metallurgical testing has indicated that copper, zinc, gold, silver, and lead from the deposit can be recovered efficiently, supporting the operational flexibility of future processing plants.

Broader Project Workstreams

Alongside the Sulphide City drilling campaign, QMines is advancing a pit optimisation study at the Scorpion deposit to guide initial mine planning. Pre-feasibility level test work is also underway to determine the most effective processing methods and evaluate the advantages of blending ore from different deposits.

A scoping study is assessing how multiple projects can be integrated to capture operational efficiencies. The results will feed into an updated pre-feasibility study, which is scheduled for release in the first half of 2026, shaping the company’s next growth phase.
