Trevali's Santander Mine production exceeds 2014 guidance

January 21, 2015
Annual production of 50.4 million lbs zinc, 23.3 million lbs lead and 914,600 ounces silver

Vancouver, British Columbia...Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV; BVL: TV; OTCQX: TREVF; Frankfurt: 4TI) reports preliminary production results for its fourth quarter ("Q4") ending December 31, 2014 of approximately 11.2 million payable pounds of zinc, 7.1 million payable pounds of lead and 241,600 payable ounces of silver from the Santander Mine in Peru (see Table 1).

Full-year 2014 Santander production was approximately 50.4 million payable pounds of zinc, 23.3 million payable pounds of lead and 914,600 payable ounces of silver, exceeding the Company's modified production guidance estimate for the year.

2014 full-year recoveries averaged 88% for zinc, 85% for lead and 75% for silver. Annual mill throughput was 709,140 tonnes. Average head grades were 4.24% Zn, 1.89% Pb and 1.64 oz/ton Ag with production of 54,204 tonnes of zinc concentrate averaging 50% Zn and 19,375 tonnes of lead-silver concentrate averaging 57% Pb and 46.7 oz/ton Ag for the year.

Average recoveries for Q4-2014 were 88% for zinc, 88% for lead and 80% for silver. Q4 throughput at the 2,000-tonne-per-day-rated Santander processing complex was 185,862 tonnes, giving an average daily throughput of approximately 2,100 tonnes. Average head grades of 3.65% Zn, 2.12% Pb and 1.56 oz/ton Ag were realized to produce approximately 12,050 tonnes of zinc concentrate averaging 50% Zn and 5,815 tonnes of lead-silver concentrate averaging 59% Pb and 43.7 oz/ton Ag.

"We are encouraged with our first commercial production year at Santander and particularly pleased with the Q4 mill performance where we achieved above design through-put and recoveries of all metals. We will continue to focus on site optimization and business efficiencies in 2015 in order to maximize site-performance prior to anticipated Zn price strengthening later this year as global supply constraints are forecast to commence," stated Dr. Mark Cruise, Trevali's President and CEO. "2015 stands to be another milestone year for Trevali as we build upon the successes realized at Santander and commission our Caribou Mine in New Brunswick in the second quarter."

Statements containing forward-looking information express, as at the date of this news release, the Company's plans, estimates, forecasts, projections, expectations, or beliefs as to future events or results and the company does not intend, and does not assume any obligation to, update such statements containing the forward-looking information. Such forward-looking statements and information include, but are not limited to statements as to: the accuracy of estimated mineral reserves and resources, anticipated results of future exploration, and forecast future metal prices, anticipated results of future electrical sales and expectations that environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of mineral reserves. These statements reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the Company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies.

These statements reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements contained in this news release and the company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in spot and forward markets for silver, zinc, base metals and certain other commodities (such as natural gas, fuel oil and electricity); fluctuations in currency markets (such as the Peruvian sol versus the U.S. dollar); risks related to the technological and operational nature of the Company's business; changes in national and local government, legislation, taxation, controls or regulations and political or economic developments in Canada, the United States, Peru or other countries where the Company may carry on business in the future; risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, industrial accidents, unusual or unexpected geological or structural formations, pressures, cave-ins and flooding); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom the Company does business; inadequate insurance, or inability to obtain insurance, to cover these risks and hazards; employee relations; relationships with and claims by local communities and indigenous populations; availability and increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits and the presence of laws and regulations that may impose restrictions on mining,; diminishing quantities or grades of mineral reserves as properties are mined; global financial conditions; business opportunities that may be presented to, or pursued by, the Company; the Company's ability to complete and successfully integrate acquisitions and to mitigate other business combination risks; challenges to, or difficulty in maintaining, the Company's title to properties and continued ownership thereof; the actual results of current exploration activities, conclusions of economic evaluations, and changes in project parameters to deal with unanticipated economic or other factors; increased competition in the mining industry for properties, equipment, qualified personnel, and their costs. Investors are cautioned against attributing undue certainty or reliance on forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. The Company does not intend, and does not assume any obligation, to update these forward-looking statements or information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.

Trevali's production plans at Caribou-Halfmile-Stratmat and Santander are based only on Indicated and Inferred Mineral Resources and not Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is therefore no certainty that the conclusions of the production plans and Preliminary Economic Assessment (PEA) will be realized. Additionally where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

We advise US investors that while the terms "measured resources", "indicated resources" and "inferred resources" are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize these terms. US investors are cautioned not to assume that any part or all of the material in these categories will ever be converted into reserves.
