"Santander delivered yet another strong quarter with record mill throughput and site cash costs remaining in line with the recent recently reduced 2016 cost guidance. Santander remains one of the lowest-cost, most efficient operating mines in the Central Mineral Belt of Peru. Additionally, stronger zinc prices in Q2, versus Q1, benefitted the Company's operations and we're also seeing a significantly stronger metal price environment so far in Q3 with zinc prices touching 15-month highs," stated Dr. Mark Cruise, Trevali's President and CEO. "Trevali also recently announced Commercial Production at its Caribou Zinc Mine in New Brunswick where similar optimization initiatives are being applied to boost the efficiencies at the operation. As zinc fundamentals continue to look increasingly bullish, Trevali remains well positioned as the only primary zinc producer on the TSX and one of only a few globally."

Santander Production Statistics

Santander Sales Summary:

Santander Zinc Mine, Peru

Production:

Santander operations delivered another excellent quarter with production of 15.2 million payable pounds of zinc, 5.6 million payable pounds of lead and 222,121 payable ounces of silver. Approximately 219,086 tonnes of mineralized material was processed through the mill with underground mine production of approximately 177,415 tonnes.

Metal production remains in line with the recently increased 2016 annual guidance of 57-60 million pounds of payable zinc in concentrate grading approximately 50% Zn, 22-25 million pounds of payable lead in concentrate grading approximately 56-58% Pb and 800,000-1,000,000 ounces of payable silver.

The mill also continues to perform at above design recoveries with Q2-2016 recoveries averaging 89% for zinc, 87% for lead and 73% for silver. Average head grades were 4.16% Zn, 1.39% Pb and 1.32 oz/ton Ag with production of 16,601 tonnes of zinc concentrate averaging 49% Zn and 4,865 tonnes of lead-silver concentrate averaging 55% Pb and 43.7 oz/ton Ag.

During the quarter, the Company sold approximately 15.2 million pounds of zinc, 5.7 million pounds lead and 222,166 ounces of silver. Revenues for the first quarter were approximately US$22.4 million with the average realized metal prices in USD for the quarter of $0.89 per pound of zinc, $0.78 per pound of lead, and $17.09 per ounce of silver.

Q2 cash costs were approximately US$35.64 per tonne, on track with the recently reduced 2016 preliminary annual cost guidance of US$35-$38 per tonne milled (down from the previous guidance of US$40-$43 per tonne milled). The cost savings are primarily attributed to the increased production and implementation of site-wide business initiatives, thus a larger impact on fixed costs as well as the efficiencies and cost cutting measures achieved to date. (Please refer to Non-IFRS Measures in the June 30, 2016 Management Discussion and Analysis).

The Company also received the additional geochemical assay results from its 2016 resource conversion and exploration program which is testing the deeper levels below the currently defined resources of the Magistral North and Central deposits. As previously noted the majority of drill holes continue to return thick intervals of multiple stacked massive sulphide replacement mineralization whose zinc, lead and silver grades are materially higher (typically ranging from approximately 25% to +100%) than those currently being actively mined and processed. All zones including the newly discovered, emergent Oyon zone remain open for expansion and the Company believes that there is very significant resource potential remaining in all three zones where limited down-dip drilling has occurred. During the third quarter diamond drilling will test the depth extents of the Magistral Central and Fatima zones. Please see the Company's news releases dated April 7, 2016 (TV-NR-16-09) and June 2, 2016 (TV-NR-16-12) for additional details.

Outlook:

Santander operations continue in steady state 2,000 tonne-per-day nameplate production with daily production commonly exceeding this by approximately 15-to-25%. The Company continues to work with partner Glencore's local subsidiary, Empresa Minera Los Quenuales S.A., to maximize and further improve operational efficiencies.

An approximate 3,000-metre underground drill program is in progress in order to convert inferred tonnes to a higher confidence category and to follow-up on 2015 exploration successes that tested the deeper levels below the currently defined resources of the Magistral zones. Contingent on results, additional drilling may occur. The program will continue to define and potentially expand the newly discovered Rosa, Fatima and emergent Oyon lead-silver-zinc zones in addition to the Magistral zones that all remain open for expansion at depth.

Caribou Zinc Mine, Canada

The Company continued to successfully advance Caribou commissioning activities during Q2 culminating with the declaration of entering Commercial Production as of July 1, 2016.

Focus continues to reach design mill throughput including associated recoveries and concentrate quality. Scheduled mill optimization initiatives during the third quarter include: completion of the SAG mill modifications - primarily installation of the newly designed lifters and shell liners; mineralogical and size-by-size analysis to track progress; ongoing mill water chemistry trials; Zn and Pb cleaner density trials; completion of recommended pumping infrastructure upgrades and implementation / upgrading of site-wide preventative maintenance program.

Mine optimization initiatives include but are not limited to the ongoing 10,000-metre definition drilling and resource conversion program, modification of drill-blast designs, targeted fleet efficiency, roadway upgrades and enhanced fleet maintenance.

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.
