Amerigo Resources Ltd. kicked off commissioning of the new rougher flotation circuit as part of the phase-two expansion at the company's Minera Valle Central copper project in Chile.
Copper concentrates from the new flotation circuit are being processed in the existing cleaner flotation circuit, according to a Sept. 5 release.
The construction of the new cleaner flotation circuit is expected to be completed this month, while construction of Minera Valle Central's molybdenum circuit would be finished in October.
As a result, the company's copper production is increasing, and unit costs are dropping in line with its guidance.
Amerigo expects to produce 65 million to 70 million pounds of copper at a cash cost of C$1.45 to C$1.60 per pound this year.
The phase-two expansion will boost copper production from Minera Valle Central to between 85 million and 90 million pounds per year and lower the cash cost to C$1.45/lb.
