The monthly totals to February 11th, were 1550 tonnes milled for production of 47 tonnes of concentrate grading 8.4 kg/t silver. Average month to date silver feed grade for February was 329 g/t at 77% recovery. This feed grade result is similar to the estimated resource grade of 332 g/t in the NI 43-101 report by Orequest 2009. Gold results are pending from the accredited lab of SGS in Durango, Mexico. Silver assays are from the on-site laboratory using aqua regia digestion followed by AA spectroscopy. Weekly check samples for silver and gold are sent to SGS, Durango.
Silver recovery of 77% was an improvement over January results of 70% when 1793 tonnes were processed for the production of 72 tonnes of concentrate grading 5 Kg/t silver and 28.3 g/t gold. The mineralized zone where the bulk sample has been extracted is partially oxidized and near the surface. Efforts are continuing to be made at the plant to improve the recovery.
