InvestorNewsBreaks — McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) Releases Report on Phase 1 Testing

McEwen Mining (NYSE: MUX) (TSX: MUX), a gold and silver producer with operations in Nevada, Canada, Mexico and Argentina, and McEwen Copper Inc. have released results from the recently completed phase 1 copper heap leaching metallurgical tests. The tests were conducted at SGS Chile Limitada in Santiago, Chile, with test results produced utilizing conventional bio-heap leaching technology. Final phase 1 results indicate an increase in the average recovery to 76% in an estimated 230 days of leaching over the planned 27-year life of the project. The report also showed average net acid consumption was reduced by 8.3% relative to the Preliminary Economic Assessment (“PEA”). The announcement noted that the potential impact of the 3.2% increase in average recovery and 8.3% reduction in net acid consumption could be illustrated by selectively adjusting the PEA Base Case financial model, which results in a life of mine copper cathode production increase of 172,000 tonnes and an after-tax NPV(8%) increase of approximately $262 million.
