:: Trevali Commences Concentrate Production at Santander Mine


Trevali Mining Corporation wishes to announce that it has commenced zinc and lead-silver concentrate production from the metallurgical plant at the Santander Mine in Peru.

The Crushing, Transfer, Grinding (all four mills), Flotation and Tailings circuits are all operational and undergoing commissioning and optimization.

As part of the commissioning process the mill is currently processing stock-piled mineralized feed during day-shift and fine tuning the plant and optimizing the reagent schemes and run criteria following each run during the subsequent night-shift as required.

The Company currently has 156,945 tonnes of mineralized material grading 4.9% Zn, 1.2% Pb, 0.22% Cu and 1.5 oz/T Ag available for commissioning.

A video of the Santander mineral processing operations (crushing, milling and flotation/recovery) is available for viewing on Trevali’s website at: www.trevali.com/s/videos.asp.

“Commencing metal concentrate production from our Santander Mine is a major achievement for Trevali. We now aim to ramp-up operations to the planned 2,000-tonne-per-day throughput," stated Dr. Mark Cruise, Trevali’s President and CEO. “This milestone is a testament to the hard work and dedication of the Trevali - Glencore construction teams as well as our contract partners that continue to play a vital role in our success."
