The expansion project at the Cozamin mine, in Mexico, is set to deliver an even better outcome than previously thought, with base metals miner Capstone Mining now forecasting an increase in production of between 50-million and 55-million pounds of copper and 1.4-million to 1.5-million ounces of silver.
The expansion project, which was announced in late 2018, involves debottlenecking the mine with a one-way ramp system. It was previously forecast to improve production by between 40-million and 45-million pounds.
