Santander Operations, Peru

Production:

Approximately 190,498 tonnes of mineralized material was processed through the mill in Q2-2015. Underground production was approximately 191,259 tonnes for the quarter, and was sourced primarily from the Magistral North-Rosa and Magistral South zones. Magistral Central was in a development cycle with scheduled production from the zone expected to increase throughout the remainder of the year.

Production results for the second quarter were 13.7 million payable pounds of zinc, 8.7 million payable pounds of lead and 291,177 payable ounces of silver.

The mill continued to perform at above design recoveries with Q2-2015 recoveries averaging 90% for zinc, 88% for lead and 78% for silver. Mill throughput for the quarter was 190,498 tonnes. Average head grades were 4.27% zinc, 2.47% lead and 1.85 oz/ton silver with production of 14,708 tonnes of zinc concentrate averaging 50% Zn and 7,081 tonnes of lead-silver concentrate averaging 59% Pb and 39.46 oz/ton Ag.

During the quarter, the Company sold approximately 13.2 million pounds, 8.7 million pounds, and 290,879 ounces, of zinc, lead and silver respectively. Revenues for the second quarter was approximately $31 million, with average realized metal prices for the quarter of US$0.95 per pound of zinc, US$0.82 per pound of lead, and US$16.33 per ounce of silver. Cash costs were approximately $45 per tonne in line with cost guidance for 2015 (Please see Cautionary Note on Forward Looking Statements at the end of this document).

Outlook:

The Santander operation is currently in steady state 2,000 tonne-per-day nameplate production.The Company continues to work to maximize and improve operational efficiencies. An approximately 6,000-metre, predominantly underground, drill program commenced during the second quarter and will continue throughout 2015 in order to convert inferred tonnes to a higher confidence category. This program will also to continue to define and potentially expand the newly discovered Rosa and Fatima lead-silver-zinc zones.

Production guidance for 2015 from the Company's Santander mine is remains unchanged at approximately 48-50 million pounds of payable zinc (in concentrate grading approximately 50% Zn), 23-25 million pounds of payable lead (in concentrate grading approximately 55-57% Pb) and 850,000-950,000 ounces of payable silver reporting to the Pb concentrates. Site cash costs for 2015 are estimated at US$48-51 per tonne milled. (Please see Cautionary Note on Forward Looking Statements at the end of this document).

Caribou Operations, New Brunswick

Commissioning of the 3,000 tonne-per-day Caribou mill commenced during the quarter with progress to date in line with Company expectations. Based on experience garnered from Santander operations the Company adopted a phased commissioning plan initially using lower-grade feed as the operators familiarize themselves with the various recovery circuits and reagent characteristics.

All critical mill circuits that is, Crushing - Grinding - Zn and Pb flotation - Concentrate Filters Metallurgical and Geochemical laboratories and Concentrate handling/load out have been either fully replaced, refurbished or repaired where necessary and available for utilization. Initial focus will be on the Zn circuit to be followed by Pb (Ag) in the third quarter and finally by the Cu circuit following its installation. External specialists have been mobilized to site in order to provide technical support and training.

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.
