Wednesday, Nov 28, 2012

Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(TSX:TV.WT)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) reports that ongoing development at its Santander Zinc-Lead-Silver Mine in west-central Peru is in the final phase with initial mining and milling operations currently scheduled to commence in Q1-2013. All critical mill and processing infrastructure is now in place and underground development continues to progress well with 1.8 kilometres of ramp completed to date. Approximately 100,000 tonnes of mineralized material averaging 5.6% zinc, 0.65% lead and 1.65 oz/t silver has now been stockpiled on surface for processing upon commissioning of the 2,000 tonne-per-day plant. There are currently over 900 construction workers, contractors, miners and management staff on site involved in the final development process.

SITE INFRASTRUCTURE

All core site infrastructure is now complete and fully operational - accommodation units, catering facilities, and various mine planning and site offices.

Construction of the project's 65-kilometre transmission-line to the National Grid has been completed. Energization of the power-line is currently being coordinated with the Peruvian regulator in order to minimize disruptions with local end-users. It is anticipated that the Santander mine site will be accessing power from the Peruvian Grid prior to year-end. In the interim, during this the final construction phase, site is being powered by the Company's run-of-river power station at Tingo and supplemented by a combination of generators and excess power from a neighbouring mining unit.
