ABOUT TREVALI MINING CORPORATION

Trevali is advancing two polymetallic (zinc-lead-silver-copper) deposits to production in Canada and Peru – the Halfmile and Santander mine projects respectively. In Canada, Trevali has the Halfmile and Stratmat polymetallic deposits in the Bathurst Mining Camp of northern New Brunswick, and the past-producing Ruttan copper-zinc mine in northern Manitoba. Mine development is currently underway at the Halfmile Mine Project with a planned production rate of 2,000-tonnes-per-day anticipated to commence by year-end 2011.

In Peru, the Company has the Santander zinc-lead-silver mine project and the former-producing Huampar silver mine, both located in the Central Peruvian Polymetallic Belt. At the planned 2,000-tonne-per-day Santander operation, mine commissioning is anticipated to commence in the first half of 2012 with full production to follow immediately thereafter. Additionally through its wholly-owned 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.
