Santander Operations, Peru

Santander operations delivered another exceptional quarter with production of 13.7 million payable pounds of zinc, 6.4 million payable pounds of lead and 221,324 payable ounces of silver. Approximately 209,188 tonnes of mineralized material was processed through the mill with underground mine production of approximately 175,579 tonnes.

Metal production remains in line with 2016 annual guidance of 52-55 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 continues to perform at above design recoveries with Q1-2016 recoveries averaging 89% for zinc, 88% for lead and 76% for silver. Average head grades were 3.93% Zn, 1.66% Pb and 1.32 oz/ton Ag with production of 14,840 tonnes of zinc concentrate averaging 49% Zn and 5,469 tonnes of lead-silver concentrate averaging 56% Pb and 38.7 oz/ton Ag.

During the quarter, the Company sold approximately 13.0 million pounds, 6.3 million pounds, and 210,427 ounces, of zinc, lead and silver respectively. Revenues for the first quarter were approximately US$20 million with the average realized metal prices in USD for the quarter of $0.82 per pound of zinc, $0.82 per pound of lead, and $15.32 per ounce of silver.

Q1 cash costs were approximately US$32.22 per tonne, significantly below the Company's previous annual 2016 cost guidance. Consequently, the Company has revised its 2016 preliminary annual cost guidance to US$35-$38 per tonne milled (down from 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 see non-IFRS measures at the end of this MD&A).

During the quarter the Company also received the final geochemical assay results from its 2015 exploration program, which tested the deeper levels below the currently defined resources of the Magistral zones. In summary the majority of the drill holes intersected zinc grades higher than those in current mining operations with values ranging from 3.52% to 12.98%. The three Magistral deposits all 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 (see March 22, 2016 - TV-NR-16-07 news release).

Santander operations continue at steady state 2,000 tonne-per-day nameplate production with site typically exceeding throughput by approximately 15-20% on a daily basis. The Company continues to work with partner Glencore's local subsidiary, Empresa Minera Los Quenuales S.A., to maximize and improve operational efficiencies.

An approximate 3,000-metre underground, drill program is currently 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, which all remain open for expansion at depth.

The Company also provides a mine and mill commissioning update for its Caribou Zinc Mine in the Bathurst Mining Camp of northern New Brunswick. A detailed description and discussion is provided below and progress highlights are as follows:

Caribou Zinc Circuit Summary

During Q1-2016 and year-to-date ("YTD") the Caribou metallurgical team and partner Glencore continued with the implementation of the metallurgical performance plan that mainly focuses on increasing zinc recoveries to entitlement ranges as outlined in the Caribou PEA report (see Technical Report on Preliminary Economic Assessment for the Caribou Massive Sulphide Zinc-Lead-Silver Project, Bathurst, New Brunswick, Canada prepared by SRK Consulting (Canada) Inc., on the Company's website or on SEDAR).

The Company continues to focus on highlighted areas for metallurgical improvement including decreasing the primary grind size, improved zinc-cell mixing and retention times with modifications to be implemented during ongoing scheduled maintenance periods (please see News Release TV-NR-16-10, April 14, 2016 for details).

Modifications completed during April, and which are ongoing, continue to focus on the primary grind and zinc circuits, and includes:

  • Improved vortex finders on three of the five cyclones, which are successfully pushing more material to the mills for grinding and resulting in feed size reduction from approximately 36-41 microns to 22 microns on the modified cyclones (note optimal target primary grind is approximately 30 microns).
  • Zinc bank splitter box improvements completed and residence time in the zinc banks is essentially balanced.
  • Zinc Cleaner density trials have commenced and are ongoing.
  • Smaller ?_-inch charge media supply is steady and currently converting Ball Mill 1 charge to the same.
  • Plant-scale mineralogical reports received and indicate a high degree of liberated sphalerite (approx. 89% volume - zinc) with very little "locked" or theoretically unrecoverable material. On the Pb circuit, minimum material reported to the tails (approx. 3%) as liberated galena, highlighting excellent performance. Mineralogy also indicates that the IsaMills are preforming as designed.
  • Initial water chemistry test work indicates that Zn recoveries are adversely affected by the calcium content of the plant process water, that is, high Ca content results in subdued Zn recoveries. The plant reagent mix was adjusted accordingly and returned 80.9% Zn recoveries to produce a concentrate grading 50.8% Zn. The metallurgical team is currently focusing on optimum reagent addition points for Ca precipitation.

Ongoing scheduled optimization initiatives during Q2 include:

  • SAG Mill modifications, primarily the newly designed lifters and shell liners (fabrication in progress) and charge from late-May onwards.
  • IsaMill redundancy test work.
  • Test-work and implementation of pumping recommendations and pumping station upgrades in June-July in order to maintain consistent cyclone feed pressures that have been impacted by fine grind frothing.
  • New instrumentation (flow metres and pressure sensors) to enable enhanced thickener performance in April -- May.
  • Increase the number of sample stations for the on-stream sample analyzer -- April-May.

Caribou Mining

Underground production during the month averaged 1,952 tonnes-per-day at average grade of 6.0% Zn, 3.0% Pb and 2.7 oz/ton Ag.

Underground production YTD (end of April) averaged 2,062 tonnes-per-day at average grade of 6.0% Zn, 2.8% Pb and 2.4 oz/ton Ag. With mill recoveries, specifically Zn, approaching target entitlement range levels the Caribou team is refocusing on underground operations and plans to ramp production to 2,500-2,700 tpd in Q2.

Ongoing mine optimization initiatives include mobilization of an additional scoop to improve fleet support and efficiency (scheduled to arrive late May), decreasing feed/waste and average haul distances, and restructuring of technical supervision to provide 7-day support to the mine team.

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.
