ABOUT TREVALI MINING CORPORATION

Trevali is rapidly fast-tracking two advanced polymetallic deposits to production in Canada and Peru – the Halfmile and Santander projects respectively. In Canada, Trevali holds the Halfmile and Stratmat polymetallic deposits near Bathurst, New Brunswick, and the Ruttan copper-zinc deposit in northern Manitoba. Advanced permitting and engineering studies are in progress at Halfmile with proposed production at a rate of 2,000-tonnes-per-day, anticipated to commence in 2011.

At Santander, in conjunction with our partner 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 wholly owned subsidiary, Trevali Renewable Energy Inc., the Company is undertaking a significant upgrade of the 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.

The common shares of Trevali are currently listed on the TSX (symbol TV). For further details on Trevali, readers are referred to the Trevali's web site (www.trevali.com) and to Canadian regulatory filings on SEDAR at www.sedar.com.
