"We remain pleased with the continued strong operational results from our Santander zinc mine where we've seen ongoing efficiencies realized throughout 2015 despite a weakened commodity price climate during the second half of the year," stated Dr. Mark Cruise, Trevali's President and CEO. "The Company currently has in excess of $20 million in the treasury and continues to advance the commissioning of the Caribou zinc mine, which when in full production is anticipated to substantially boost the Company's zinc output and position the Company to benefit from forecast increases in the zinc price looking forward. Year-to-date zinc remains one of the best performing metals and annual 2016 smelter Treatment Charges have decreased materially, having reversed approximately 80% of its 2012-2015 gains in a single year, reflecting a tightening global zinc concentrate market. It is noteworthy that global zinc supply is on-track to decrease by record levels in both absolute tonnages and percentage-wise in 2016, which general consensus suggests should result in very material strengthening in zinc prices going forward."

2015 Financial Results Conference Call

The Company will host a conference call and audio webcast at 10:30 a.m. Eastern Time (7:30 a.m. Pacific Time) on Thursday, March 31, 2016 to review the 2015 annual financial results. Participants are advised to dial in 5-to-10 minutes prior to the scheduled start time of the call.

Santander Operations, Peru

Santander achieved outstanding operational results in 2015. The Company exceeded expected production guidance for the year, which was estimated at approximately 48-50 million pounds of payable zinc, 23-25 million pounds of payable lead and 850,000-950,000 ounces of payable silver, achieving actual production results of 54.1 million pounds of payable zinc, 30.2 million pounds of payable lead and 1,055,965 ounces of payable silver. Estimated 2015 cash costs of US$48-51 per tonne milled was also bettered, coming in at US$42.65 per tonne milled for the year (2014 - US$47.33). The decrease in per tonne costs is due to higher mill throughput and continued cost optimization throughout 2015 versus 2014. In addition, many of the cost and optimization savings were realized in the renegotiations of key contracts, fuel and power for the mine and mill. ⁽²⁾

The mill continued to perform at above design recoveries averaging 90% for zinc, 89% for lead and 77% for silver. Mill throughput for the year was 778,151 tonnes. Average head grades were 4.14% Zinc (Zn), 2.09% Lead (Pb) and 1.66 oz/ton Silver (Ag) with production of 58,232 tonnes of zinc concentrate averaging 50% Zn and 24,962 tonnes of lead-silver concentrate averaging 58% Pb and 40 oz/ton Ag.

During the year, the Company sold approximately 52.9 million pounds, 30.4 million pounds, and 1.1 million ounces of zinc, lead and silver respectively. Annual revenues were approximately US$83.2 million, with average realized metal prices for the year of US$0.84 per pound of zinc, US$0.77 per pound of lead and US$15.67 per ounce of silver.

The Company also received additional assay results for 10 holes from its 2015 resource definition and expansion program (see March 22, 2016 - TV-NR-16-07 news release). Drilling intersected high-grade zinc mineralization and successfully expanded the Magistral Central and South zones: intercepts ranged from 5 to 15 metres downhole thickness (est. at 85-95% of true width) with grades ranging from 4.09 to 11.5% Zn, 0.04 to 3.2% Pb and 5.6 to 71 g/t/ Ag.

Significantly, the results to date suggest that mineralization width and grade is increasing at depth and that the Magistral South and Central zones have merged into a single zone based on results to date (at depth). The area sits above and is spatially associated with a very large, strong geophysical anomaly (Down-Hole Electromagnetic anomaly approximately 300-by-300 metre modelled conductive plate) that extends at least an additional 150-200 metres deeper than current drilling and remains open to the north, south, east and at depth.

Outlook

Santander operations continue at steady state 2,000 tonne-per-day nameplate production. The Company continues to work with partner, Glencore's local subsidiary, Empresa Minera Los Quenuales S.A. ("Los Quenuales"), to maximize and improve operational efficiencies.

The preliminary 2016 production guidance estimate for the Santander zinc mine is:

52-55 million pounds of payable zinc in concentrate grading approximately 50 percent Zn; 22-25 million pounds of payable lead in concentrate grading approximately 56-58 percent Pb; and 800,000-1,000,000 ounces of payable silver

Site cash costs for 2016 are estimated at approximately US$40-US$43 per tonne milled (please see Cautionary Note on Forward Looking Statements at the end of this document).

In addition, an approximate 3,000-metre underground drill program is planned for the first half of 2016, which is anticipated to convert inferred tonnes to a higher confidence category and to follow-up on 2015 exploration successes. Contingent on results, additional drilling may occur. The program will continue to define and potentially expand the recently discovered Rosa and Fatima lead-silver-zinc zones in addition to the Magistral zones, all of which remain open for expansion at depth.

In Canada, the Company continues to focus on the ongoing commissioning of its Caribou zinc mine and mill to achieve design throughputs from both the mine and mill, including associated recoveries and concentrate quality. The Company will continue to provide regular updates until declaration of commercial production, which based on progress to date is currently estimated to occur in mid-year 2016.

Trevali's production plan at the Caribou Mine is based only on measured, indicated and inferred resources, and not mineral reserves, and does not have demonstrated economic viability. Trevali's production plan at the Santander Mine is based only on indicated and inferred mineral resources, and not mineral reserves, and does 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.
