Las Tojas (Don Mario)

Las Tojas is a series of subparallel gold-bearing shear zones hosted by a quartz-amphibole-garnet-magnetite-cordierite schist. AMEC (Peru) S.A. completed a National Instrument 43-101 resource calculation of the Las Tojas gold deposit effective December 19, 2008.

Type '000 Tonnes Gold, grams per Tonne Gold, Ounces

Total M&I 387 2.21 27,440
Inferred 76 1.80 4,398

During fiscal 2008, it was decided to process this gold mineralization. To try to maintain the past levels of annual gold production, a generator and ball mill were commissioned in June 2009 to increase throughput to about 2,000 tonnes per day at the Don Mario Mine. Nonetheless, year-on-year production will decrease. The potential to discover more gold on trend with the Las Tojas deposit is high and exploration is ongoing.
