VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 12, 2009) - Trevali Resources Corp. ("Trevali" or the "Company") (CNSX:TV)(PINK SHEETS:TREVF)(FRANKFURT:4TI) is pleased to announce that the recent discovery and re-assaying of historic diamond drill core from the Puajanca target has confirmed the presence of a significant silver-lead-zinc mineralized zone extending to depth on the Santander Mine project in Peru.

Hole PJ-2E, a historic exploration hole, intersected significant mineralization from approximately 100 metres down-hole - 75 metres vertical extent. The hole terminated at 106.7 metres down-hole in massive sulphide mineralization - the final sample is 2.12 metres grading 186 g/t silver, 3.6% lead and 3.36% zinc.

Hole PJ-3E intersected a very broad zone of disseminated and vein-style mineralization from approximately 150 metres down-hole - within which numerous higher-grade intervals occur down to vertical depths of 225 metres (Table 1).

The high silver-lead to zinc mineral ratios are similar to the company's silver-rich Magistral Norte and Central orebodies and are indicative of the upper portions of a productive mineralized system, the fourth identified by the Company to date. Mineral system analysis and empirical observations based upon the three Magistral orebodies and the former Santander Pipe suggest very significant additional depth potential at Puajanca, conservatively estimated to be on the order of 350 to 500 metres or more.

Geologically the Puajanca target, in conjunction with the former producing Santander Pipe, defines an important second mineralization fairway - that extends over approximately 3 kilometres strike length - on the Company's large 44-square kilometre property.
