Silver Standard Updates Pirquitas Project
VANCOUVER, BC - Silver Standard Resources Inc. reported that its wholly-owned Pirquitas Mine in Jujuy, Argentina, is on schedule to commence concentrate production in the current quarter. Initial production will focus on the processing of over 400,000 tonnes of run-of-mine grade jig tails from historic operations and then transition to material from the open pit. To date, approximately five million tonnes of material has been moved from the Pirquitas open pit and stockpiling of ore has commenced.
At current metal prices, the silver and tin concentrates account for over 95% of the anticipated revenue from the mine. As a result, the silver circuit will be optimized first, followed by the tin circuit. A decision to complete the zinc circuit is dependent on the results of metallurgical testwork to be received on increasing silver recoveries. Process equipment purchased for the zinc circuit may be better served increasing the silver recovery.
As reported in the company's third quarter 2008 conference call, inflation in wages and local inputs continues to place pressure on the US$220 million estimated capital cost of the mine. In developing this cost estimate in November 2007, Silver Standard estimated inflation for wages and other inputs within Argentina significantly higher than the official rate. With inflation exceeding company estimates, the estimated cost to complete the construction of Pirquitas has increased to US$230 million or 5% over the 2007 estimate. With eight months of mining experience and in-country administration, the company estimates that mining, milling and administration costs will now average US$26/tonne over the life of the mine.
With production ramping up through Q2, Pirquitas is expected to produce in excess of six million ounces of silver in 2009 with full production in excess of 10 million ounces in 2010.
