New East-West Trending Mineralized Zone Represents High-Grade Resource Expansion Potential at Trevali's Santander Silver-Lead-Zinc Project in Peru

Deep intercepts expand Magistral Norte and Sur zones Highlights include: 13.6 metres at 11.6 oz (361.5 g/t) Silver equivalent 4.45 metres at 32.4 oz (1006.9 g/t) Silver equivalent

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 19, 2009) - Trevali Resources Corp. ("Trevali" or the "Company") (CNSX:TV)(PINK SHEETS:TREVF)(FRANKFURT:4TI) is pleased to announce that diamond drilling has intersected a new zone of very significant near surface mineralization at the Magistral Norte sulphide body on the Santander silver-lead-zinc mine project in Peru. Hole SAN-098, a combined geotechnical - exploration hole, intersected multiple zones of predominantly east-west trending vein and replacement footwall mineralization from approximately 11 metres below surface including two very substantial zones at 38.7 and 94.8 metres downhole that intersected 13.8 metres and 14.8 metres of 13.9 ounce (433.4 g/t) and 11.1 ounce (346.7 g/t) silver equivalent mineralization respectively.

In addition assay results have successfully confirmed the presence of significant silver-lead-zinc mineralization at depth on the Magistral Norte and Sur zones (Table 1). Mineralization remains open on all three Magistral sulphide bodies. Mineral system analysis indicates that very considerable depth potential, on the order of 350 to 500 metres, remains on all three currently defined sulphide bodies. A National Instrument 43-101 resource estimate is imminent.

There are three high-priority targets scheduled for drill testing:

- The newly discovered east - west trending zones intersected in SAN-098 are interpreted to represent feeder zones to the currently defined Magistral sulphide bodies. Similar trending zones have been identified at both Magistral Central and Sur but require drill testing and may represent extensive near-term resource expansion potential. These productive zones intersect prospective lithologies to the East where the entire host-sequence is preserved representing high-priority exploration targets.

- Out-cropping high-grade silver mineralization with values up to 17.9 oz (558 g/t silver) at Puajanca remains a high-priority drill target.

- Additionally, geophysical surveying has identified 12 other high-priority anomalies that require testing - along 17 km of strike on the same productive trend and of equal or greater extent to the pre-drilling geophysical response of the three Magistral deposits.

Project Background

The Santander silver-lead-zinc mine project is located approximately 215 km by road from Lima, in the western extent of Peru's prolific Cerro de Pasco mineral district. The mine operated from 1958-1993 targeting a single Carbonate Replacement Deposit-type pipe and manto structure, the Santander Orebody.

Substantial site infrastructure at the formerly-producing operation includes a fully refurbished 200-man camp and associated support facilities, an ore processing / concentrator plant (including various crushers, mills, flotation cells and filters able to produce zinc, lead-silver and copper concentrates) currently undergoing a refurbishment program, and the Tingo hydroelectric power-station located approximately 17 km down-valley to the west. The Santander project and the considerable existing infrastructure form a highly strategic asset in this mining district. The Company commenced exploration at Santander in November 2007 discovering three new high-grade silver-lead-zinc replacement and massive sulphide bodies to date.

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.
