Overview

Trevali Mining Corp. (TSE:TV,FSE:4TI,OTCQX:TREVF) is a mineral development company focusing on 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.

Chief Projects

Santander Mine – West Central Peru

The 4,455 hectare property contains numerous outcropping polymetallic mineralized bodies: Magistral North, Central, South, Puajanca South and the Santander Pipe. The Magistral North, Central, and South deposits are all new discoveries hosted in favorable carbonate lithologies and located a few kilometers Northwest of and along the same structural trend hosting the past producing Santander ore body that was mined from 1958 until 1992.

With key permits already in place, Trevali plans zinc-lead-silver production commencing in early 2012 at a rate of 2,000 tonnes-per-day with an anticipated production expansion to 4,000 tonnes-per-day in 2013/14. Trevali has a strategic partnership with Glencore International AG that are providing the 2,000 tonne-per-day processing plant, contract mining and manpower, and will receive a life-of-mine metals concentrate offtake agreement (at International Benchmark Terms) – greatly mitigating both financial and technical risks. Trevali retains 100% ownership of the Santander project and also plans to acquire ownership of Glencore’s processing plant via a toll charge over the initial 4 years of operation. Due to significant silver and lead credits plus low-cost hydroelectric power, Trevali anticipated that Santander will be a low cost zinc producer.

Trevali Renewable Energy Inc., a fully owned subsidiary of Trevali, will provide the Santander Mine site with inexpensive and reliable power from the Tingo hydroelectric generating facility approximately 17 km down-valley to the West and already connected to the mine site. Trevali is planning a major upgrade of the power station from its present production capacity of 1.6 MW to approximately 8.8 MW and 10 MW during the wet season. As mine production (at 2,000 tonnes-per-day) at Santander is estimated to require approximately 4 to 5 MW of power consumption, the excess power can be sold to third parties via the Peruvian National Energy grid to generate potential additional cash flow to Trevali.

Halfmile – New Brunswick, Canada

Trevali acquired the Halfmile project through its merger/acquisition of Kria Resources in early 2011. Halfmile is a polymetallic  massive sulphide (lead-zinc-copper-silver) deposit located in the Bathurst base metal camp of northeast New Brunswick. The property is situated approximately40 kilometres from Xstrata’s world-class Brunswick 12 mine.

Previous exploration was carried out on Halfmile by Xstrata Zinc and other companies in the 1960s. In February 2009, an NI 43-101 compliant resource estimate was created for the Halfmile property which revealed an indicated resource of 6.26 million tonnes at 8.13% zinc, 2.58% lead, 0.22% copper and 30.78 g/t silver. An additional inferred resource for the property revealed 6.08 million tonnes at 6.69% zinc, 1.83% lead, 0.14% copper and 20.51 g/t silver; all resources are open and used a 5.0% capped zinc equivalent cut-off grade.

In April 2011, Trevali announced initial drill results from the metallurgical test program at Halfmile’s Upper Zone. The drilling intersected substantially thigher zones of massive sulphide in the deposit – in addition to the new zones of high-grade copper in the Hanging Wall. The Company also uncovered that silver and gold grades are elevated in the lead-zinc dominant section of the massive sulphide body.

Highlights from the drilling at Halfmile include:

• 29.25 meters of 6.87% zinc, 2.23% lead, 0.46% copper, 52 g/t silver and 0.86 g/t gold
• A new copper-rich stringer zone over 3.63-to-7.0 metre drill-indicated widths with intercepts ranging from 0.86% to 2.97% copper has been identified.

Underground development is currently underway with planned production by Q4-2011 with toll milling through Xstrata’s Brunswick 12 processing facility. Initial production will be at 2,000 tonnes-per-day with a planned increase to 4,000 tonnes per days within the following 2-3 years as the satellite Stratmat deposit is developed.
