Mt Chalmers Copper-Gold Project – Test-work and Pre-Feasibility Study

QMines commissioned Como Engineers to supervise test-work for flowsheet development and a subsequent pre-feasibility study to examine the potential for extraction and sale of copper, gold, zinc and silver from a combined mining operation at the Mt Chalmers deposit. The deposit was discovered in 1860, with underground and open pit gold and copper mining undertaken periodically until 1982. The work included the design and supervision of test-work programs for the development of a 1 Mtpa stand-alone process plant. The studies investigated an operation which would produce, during the initial life of mine, 65,000 tonnes of copper, 160,000 oz of gold, 30,600 tonnes of zinc, 1.8M oz of silver and 583,000 tonnes of pyrite.
