Trevali Defines Multiple Priority Targets at Santander Zinc-Lead-Silver Project

Surface Values Up to 27.9 oz/T (955.9 g/t) Silver, 1.34 g/t Gold, and 4.8% Lead

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 8, 2011) - Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(OTCQX:TREVF)(FRANKFURT:4TI)(BVLAC:TV) is pleased to announce that ongoing multi-disciplinary exploration has defined four high priority polymetallic (zinc-lead-silver) targets for follow-up testing on its Santander Mine Project in west-central Peru.

These new targets share many similarities to the Magistral deposits prior to initial discovery drilling such as location on known productive mineral fairways / structural settings, proven host units, anomalous outcropping mineralization and/or 'productive' alteration gangue mineral assemblage and spatial association with geophysical (magnetic) anomalies (Table 1 & Fig. 1-2). All four prospects have anomalous rock and/or soil geochemical signatures displaying elevated manganese, lead, silver and zinc values.

"Our latest exploration continues to demonstrate the significant mineral potential on the Santander project," stated Dr. Mark Cruise, President & CEO of Trevali. "Concurrent with mine development presently underway on the three Magistral deposits at Santander, we will also be undertaking exploration programs to evaluate these recently defined targets with the ultimate aim of further building the zinc-lead-silver resources on the project."

The Capilla and Nati targets have sulphide mineralization outcropping on surface. The Nati prospect consists of an outcrop of skarn alteration with disseminated mineralization surrounded by alluvial cover. Sulphide mineralization at the Capilla prospect is exposed discontinuously on surface within a 250-metre long and 1-to-2-metre wide structural corridor. Fifteen characterization samples of sulphide mineralization returned grades ranging from 27.9 - 0.5 oz/T (955.9 - 18.7 g/t) silver, 1.34 - 0.013 g/t gold and 4.8 – 0.04% lead. An additional five characterization samples in wall rock outside of sulphide mineralization had elevated but sub-economic lead and silver values. Detailed mapping and sampling are currently underway with the goal of preparing these targets for near term exploration drilling.

Trevali's exploration team has successfully discovery five new zinc-lead-silver deposits to date on its large, 44km2 property. All mineralized bodies remain open for expansion and three diamond drill-rigs are currently extending mineralization at depth – the most recent hole SAN-167 extended the Magistral Central body 130-metres down dip to approximately 480 metres below surface, intersecting 10.15 metres at 1.4 oz/T (47.7 g/t) silver, 14.4% zinc and 0.23% copper.

Bridge Loan Facility

Trevali has arranged a US$10 million Bridge Loan Facility with Resource Income Fund, L.P. of Fort Lee, New Jersey for mine development and working capital purposes. The loan will bear a fixed interest rate of 12 per cent per annum, has a term of up to three months and is secured by the pledging of the shares of the operating companies holding the Halfmile and Stratmat projects in New Brunswick. The Company has also negotiated an extension option with the Lender that would allow the Company to extend the Maturity date for up to an additional 90 days, subject to typical terms and conditions, should the same be necessary at the maturity of the Bridge Loan.

Trevali has paid a closing fee of 1.5 per cent of the Facility amount and will issue Common Stock Purchase Warrants for 500,000 shares at an exercise price set at a 10 per cent premium to the 5-day volume weighted average closing price, prior to loan closing and with a term of 12 months.

Qualified Person and Quality Control/Quality Assurance

EurGeol Dr. Mark D. Cruise, Trevali's President and CEO and a qualified person as defined by National Instrument 43-101, has supervised the preparation of the scientific and technical information that forms the basis for this news release. Dr. Cruise is not independent of the Company, as he is an officer and shareholder.

The work programs at Santander were designed by, and are supervised by, Tim Kingsley (Senior Geologist) and Mark D. Cruise, President & CEO, Trevali and who together are responsible for all aspects of the work, including the quality control/quality assurance programs. On-site personnel at the project rigorously collect and track samples which are then security sealed and shipped to ACME Laboratories, Vancouver, for assay. ACME's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Blind certified reference material is inserted at regular intervals into the sample sequence by Trevali personnel in order to independently assess analytical accuracy. Finally, representative blind duplicate samples are routinely forwarded to ACME and an ISO compliant third party laboratory for additional quality control.


Trevali is advancing two polymetallic 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 at a 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 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.

The common shares of Trevali are currently listed on the TSX (symbol TV), the OTCQX (symbol TREVF) and on the Lima Stock Exchange (symbol TV). For further details on Trevali, readers are referred to the Company's web site ( and to Canadian regulatory filings on SEDAR at
