Oct 20 (Reuters) - Canada’s Minera Andes MAI.TO posted a quarterly decline in silver and gold sales at its flagship San Jose mine in Argentina, as a result of increase in products inventory.
For the third quarter, while there was marginal change in production, sales of silver and gold were down 21 percent and 19 percent, respectively, as there was a decrease in products inventory in the same period last year.
The company said it will give details on production costs with the third-quarter results.
Earlier in the month, Minera said the discovery of nine veins of gold and silver would “significantly” extend the life of San Jose mine. [ID:nSGE6960KT]
The controversial San Jose mine is operated by Minera Santa Cruz SA, also a joint venture between Hochschild Mining Plc HOCM.L and Minera Andes.
Minera shares have risen 74 percent in value since the company resolved a dispute with Hochschild over the repayment of loans for financing the San Jose project in September. [ID:nSGE68J0KA]
