ABOUT TREVALI MINING CORPORATION

Trevali is advancing two polymetallic (zinc-lead-silver-copper) deposits to production in Canada and Peru – the Halfmile and Santander projects respectively. In Canada, Trevali has the Halfmile and Stratmat polymetallic deposits near Bathurst, New Brunswick, and the Ruttan copper-zinc deposit in northern Manitoba. Mine development is underway at Halfmile with a proposed production rate of 2,000-tonnes-per-day anticipated to commence in 2011. In Peru, the Company has the Santander zinc-lead-silver mine project and the formerly-producing Huampar silver mine, both located in the Central Peruvian Polymetallic Belt.

At Santander, in conjunction with Glencore International A.G., mine commissioning and production is anticipated to commence at 2,000-tonne-per-day in late 2011 with full production to follow immediately thereafter. Additionally through its subsidiary Trevali Renewable Energy Inc., Trevali is undertaking a significant upgrade of its wholly-owned Tingo run-of-river hydroelectric generating facility along with transmission line upgrades and extensions to allow, in addition to supplying power to the mining operation on the property, the potential sale of surplus power into the Peruvian National Energy Grid.
