The Company has completed the construction of its pumping infrastructure upgrade which is currently undergoing commissioning in order to facilitate long-range planning as mining transitions deeper in the Magistral zones, to reduce power requirements and improve overall mine efficiency.

In Q4, combined surface and underground exploration and definition drilling campaigns continued testing the down-plunge and lateral extension and continuity of Magistral and Pipe deposits. The results will be incorporated into an updated resource-reserve statement scheduled for completion by the end of the first quarter-2018. All deposits remain open for expansion and the Santander exploration team will continue to drill test the system in 2018 as part of its annual exploration campaign.

As previously disclosed, mill maintenance in the first quarter of 2018 remains on track (head of ball mill replacement on one of the four Santander mills) and will result in lower throughput with mined ore stockpiled for processing in subsequent quarters.

Caribou Mine, Canada:
Production results from Caribou for Q4 was 21.7 million payable lbs. of zinc, 8.7 million payable lbs. of lead and 249,643 payable ozs. of silver. During the quarter the mine sold 23.9 million lbs. of zinc, 8.7 million lbs. of lead, and 252,116 ozs. of silver for total revenues of $37.0 million, with average realized metal prices for the quarter of $1.45 per lb of zinc, $1.13 per lb of lead, $16.55 per oz of silver.

Mill throughput for the quarter was 252,857 tonnes with recoveries averaging 78% for zinc, 66% for lead, and 40% for silver contained in lead concentrate. Q4 underground mine production increased to 250,225 tonnes attributable to improved equipment availability and productivity.

Average head grades of the tonnes milled in Q4 were 6.02% Zn, 2.56% Pb and 2.32 oz/ton of Ag, with production of 25,021 tonnes of zinc concentrate averaging 47% Zn and 10,644 tonnes of lead-silver concentrate averaging 40% Pb and 21.8 oz/ton Ag.

The site cash operating cost during the fourth quarter of 2017 continued to trend lower at $55.14 per tonne milled, reflecting the transition from contracted to owner-operated mining and ongoing efficiencies from optimization initiatives. Direct site cash cost per zinc equivalent payable lb. produced in Q4 was $0.45 per lb. (Please refer to Non-IFRS Measures in the December 31, 2017 Management’s Discussion and Analysis).

Construction of the mill re-grind project was completed, and commissioning which commenced in Q4 is ongoing. When fully commissioned it is anticipated to result in improved zinc and lead recoveries in addition to higher-grade concentrates. Business improvement programs have been implemented to target key operational areas including production drilling support, introduction of raise-boring to improve the stope production cycle and mobile fleet optimization. These initiatives are improving mine site operational efficiencies and will continue throughout 2018.

(1)  EBITDA (earnings before interest, taxes, depreciation and amortization) is calculated by considering Company’s earnings before interest payments, tax, depreciation and amortization are subtracted for any final accounting of its income and expenses. The EBITDA of a business gives an indication of its current operational profitability and is a non-IFRS measure. See non-IFRS Measures below and in Trevali’s accompanying 2017 Management’s Discussion and Analysis.
(2)  ZnEq Payable Pounds Produced = ((Zn Payable lbs Produced x Zn Price)+(Pb Payable lbs Produced x Pb Price)+(Cu Payable lbs Produced x Cu Price)+(Au oz Payable Produced x Au Price)+(Ag oz Payable Produced x Ag Price))/Zn Price.
(3)  ZnEq Payable Pounds Sold = ((Zn Payable lbs Sold x Zn Price)+(Pb Payable lbs Sold x Pb Price)+(Cu Payable lbs Sold x Cu Price)+(Au oz Payable Sold x Au Price)+(Ag oz Payable Sold x Ag Price))/Zn Price. (All metal prices are the average realized metal price for the period).
(4)  Revenues include prior period adjustment.

A key initiative at Perkoa in 2017 was to re-commission the zinc regrind mill, which was completed in the fourth quarter, with positive impacts on recovery and concentrate grades. These benefits are expected to continue in 2018.

The Company has approved the procurement and installation of a more efficient site power generating system subsequent to the year-end.  Phase I of the project will entail the installation of two 2.5MW Heavy Fuel Oil (HFO) generators for a total estimated budget, including contingency, of $9.2 million. The project has an anticipated cost savings of approximately $7 per tonne milled. As the Company integrates the assets, further synergies are expected in supply and procurement, operational and technical support efficiencies.

2018 CONSOLIDATED PRODUCTION AND COST GUIDANCE(1,2,3)
Consolidated production guidance for 2018 remains unchanged and is estimated between 400 and 427 million pounds of payable zinc, 43.8 and 46.0 million pounds of payable lead and 1.4 and 1.47 million ounces of payable silver. Consolidated operating costs will range from $60-$66 per tonne.

(2)  Operating and cash costs are based on various assumptions and estimates, including, but not limited to: production volumes, commodity prices (Zn: $1.25/lb Pb: $1.00/lb Ag: $19/lb) and foreign currency exchange rates (N$/USD: 13.00; XOF/USD: 609; PEN/USD 3.25; C$/USD $1.25) and is a non-IFRS measure. See non-IFRS Measures below and in Trevali’s accompanying 2017 Management’s Discussion and Analysis.
(3)  Trevali’s interest is 90% of Perkoa and 80% of Rosh Pinah.

Production guidance has been provided on an annual basis but we expect moderate production fluctuations on a quarter-to-quarter basis due to mine scheduling, with modestly lower first quarter production versus the balance of the year.

Such forward-looking statements and information include, but are not limited to statements as to: consolidated production guidance for 2018, expected consolidated operating costs, cash costs (net of by-product credits), timing and costs of the proposed site power generating system, including expected cost savings, synergies in supply and procurement, operational and technical support efficiencies, expectations regarding the updated resource-reserve statement scheduled for completion by late first quarter-2018, timing and results from mill maintenance, including expected lower throughput with mined ore stockpiled for processing in subsequent quarters, the expected benefits from the zinc regrind mill, including improved zinc and lead recoveries and higher-grade concentrates, business improvement programs and improvement of site operational efficiencies, increased production gains and efficiencies, the accuracy of estimated Mineral Resources, anticipated results of future exploration, and forecast future metal prices, expectations that environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of Mineral Resources. 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.
