ARGENTINA – Yamana Gold of Toronto has announced its decision to proceed with the construction of the Cerro Moro project, a high grade, low cost gold-silver property in Santa Cruz province. In the first three years of production, output is targeted at 135,000 oz of gold and 6.7 million oz of silver annually.

The initial capital requirement is $265 million, followed by sustaining capital costs of $133 million. With a 1,000 t/d mill to be built in a single stage, production is expected to begin in the second half of 2017. Yamana expects to see all-in sustaining costs of US$547 to US$557 per oz of gold and US$7.60 to US$7.80 per oz of silver.

Ore is to be mined from small open pits as well as underground cut and fill methods. The plant flowsheet includes standard crushing, grinding and flotation with counter-current decantation and a Merrill Crowe circuit.

Cerro Moro is a low sulphidation epithermal vein deposit. The project has probable reserves of 1.95 million tonnes grading 11.38 g/t Au and 648 g/t Ag, containing 715,000 oz of gold and 40.72 million oz of silver.
