Vancouver, British Columbia...Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV; BVL: TV; OTCQX: TREVF; Frankfurt: 4TI) reports preliminary production results for its third quarter 2014, ended September 30, 2014, of approximately 12.6 million payable pounds of zinc, 6.3 million payable pounds of lead and 217,600 payable ounces of silver from the Santander Mine in Peru.

Average recoveries for the quarter were 88% for zinc, 83% for lead and 74% for silver. Q3-2014 throughput at the 2,000-tonne-per-day-rated Santander processing complex was 174,075 tonnes, delivering a mill utilization factor of approximately 97%. Average head grades of 4.40% Zn, 2.11% Pb and 1.66 oz/ton Ag were realized to produce approximately 13,466 tonnes of zinc concentrate averaging 50% Zn and 5,370 tonnes of lead-silver concentrate averaging 56% Pb and 39.0 oz/ton Ag.

Q3-2014 metal production at Santander increased versus Q2 due primarily to completion of modifications of underground workings within the Magistral North Deposit, which now incorporates portions of the recently discovered Rosa Zone (higher-grade lead and silver mineralization) into production scheduling.

2014 Production Guidance Increased
Given the performance of the mine year-to-date, Trevali has increased its 2014 full-year Santander production guidance estimate to approximately 47-50 million pounds of payable zinc, 20-23 million pounds of payable lead and 820,000 to 850,000 ounces of payable silver.
