Trevali Announces Infrastructure Upgrades in Santander District

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 24, 2010) - Trevali Resources Corp. ("Trevali" or the "Company") (CNSX:TV)(PINK SHEETS:TREVF)(FRANKFURT:4TI) is pleased to announce that the Ministerio de Transportes y Comunicaciones (Ministry of Transport and Communications) has commenced significant infrastructure upgrades on the principal roads providing access to the Company's Tingo run-of-river hydroelectric power station and the former Santander Silver-Lead-Zinc Mine Site, both of which are located in west-central Peru's world-class Central Polymetallic Belt.

  • Blasting and widening of switch-back corners.
  • Installation and maintenance of a new road surface (asphalt and packed gravel respectively).
  • Construction of permanent draining channels leading to improved surface water run-off during the wet season.
  • Strengthening of pre-existing and construction of new bridges capable of facilitating heavy equipment in addition to concentrate transport vehicles.
  • Installation of guard-rails for improved road safety.

"These upgrades will significantly decrease personnel and heavy equipment transport times to and from site," states Mark Cruise, Trevali's President and CEO. "Time savings will not only provide an economic benefit to our Santander mine project but will also yield major benefits to local communities in the district."

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 world-class Central Mineral Belt. Site infrastructure includes a fully refurbished 200-man camp and the Tingo hydroelectric power-station located 17 km down-valley to the west. The Company commenced exploration at Santander in November 2007 discovering four new high-grade silver-lead-zinc replacement and massive sulphide bodies to date. Mineralization remains open in all three Magistral deposits, the Puajanca zone and the Santander Pipe, and numerous high priority targets remain to be tested on the Company's large 100%-owned land package.
