Trevali Exceeds 2019 Production Guidance, Achieves Record Annual Zinc Production and Provides 2020 Guidance

VANCOUVER, British Columbia, Jan. 20, 2020 (GLOBE NEWSWIRE) — Trevali Mining Corporation (“Trevali” or the “Company”) (TSX: TV; OTCQX: TREVF) is pleased to release preliminary fourth quarter (“Q4”) and full year production results for 2019 and provides 2020 operating, capital and exploration expenditure guidance. All financial figures are in U.S. dollars.

Ricus Grimbeek, Trevali’s President and CEO stated, “In 2019 we started the transformation of Trevali. The Company meaningfully beat annual production guidance, the board was refreshed, a new senior management team was assembled, and we launched the T90 Program to modernize our operations and bring them down the cost curve. The Company is well positioned to be a 400-million-pound annual zinc producer with a reducing cost profile until 2022 when we intend to make a step change in production and cost as the RP2.0 Expansion Project at Rosh Pinah in Namibia is commissioned.”

Key 2019 Highlights Include:

  • Marked improvement to safety performance having reduced the Total Recordable Injury Frequency Rate by 46% in 2019 compared to 2018.
  • Exceeded 2019 zinc production guidance by producing a record annual 417 million payable pounds of zinc in 2019.
  • Total lead and silver production also exceeded 2019 guidance with 50 million payable pounds of lead and 1,489 thousand payable ounces of silver produced in 2019.
  • Refreshed the board of directors and introduced a new senior management team.
  • Launched the T90 Program inclusive of the Digital Transformation Program aimed at realizing $50 million in annual sustainable efficiencies and reducing All-In Sustaining Cost1 (“AISC”) to $0.90 per pound of zinc by the beginning of 2022.
  • Published Trevali’s inaugural annual Sustainability Report.
  • Advanced the RP2.0 Expansion Project with an investment decision poised for Q1 2020.
  • Completed the Rosh Pinah filtration & grinding upgrade project on time and on budget.
  • Discovered a third VMS lens at Perkoa below the existing mining horizons named “T3”.
  • Paid down debt of $70 million in 2019.
  • Repurchased 28.6 million shares as part of the normal course issuer bid since November 2018.

2020 Catalysts and Key Drivers

  • T90 Program: Results of the T90 Program will be highlighted and reflected in our production and financials throughout 2020.
  • RP2.0 Expansion Project: Trevali plans on publishing a pre-feasibility study by the end of Q1 2020 to support the initial long lead procurement investment decision which will be followed by the full feasibility study in Q4 2020. The feasibility study will be used to support the full execution funding decision.
  • 2019 Mineral Resources and Reserves Statement: The annual statement will be published by the end of Q1 2020.
  • 2020 Sustainability Report: The report will be published in Q2 2020 and will provide an update on the progress of our sustainability programs and initiatives as part of Trevali’s commitment to be a leader in sustainability and to providing transparency in the areas of environment, social and governance.
  • Perkoa T3 drilling program: Drilling of the 2019 discovery of T3 – the third VMS lens at Perkoa – will advance along with regional targets.
  • Santander Pipe: Infill drilling of the Santander Pipe in Peru will continue in 2020. An internal preliminary economic assessment is expected to be completed by the end of Q4 2020 which will evaluate the economic viability of incorporating the Santander Pipe ore into the existing operation.

Q4 2019 and Full Year 2019 Preliminary Production Results & 2020 Production Guidance

Total zinc production from operations totaled 105 million pounds for Q4 2019 and an annual record of 417 million pounds for the full year, exceeding the Company’s annual guidance of between 361 to 401 million pounds of zinc production. Lead and silver production for 2019 also exceeded guidance at 50 million pounds and 1,489 thousand ounces of production respectively.

Consolidated production guidance for 2020 is estimated between 380 – 410 million pounds of payable zinc, 51 – 57 million pounds of payable lead and 1,440 – 1,580 thousand ounces of payable silver.

2020 Consolidated Cost Guidance

Consolidated cost guidance for 2020 for C1 Cash Costs1 is estimated between $0.85 – $0.93 per pound of zinc and AISC1 is expected to range between $0.98 – $1.08 per pound of zinc (see Table 2). Capital expenditures for the group is forecast at $81 million, consisting of $57 million in sustaining capital, $12 million in exploration capital, and $12 million in expansionary capital, which relates to initiatives under the T90 Program, including deploying technology to improve productivity and decision making.

2020 C1 Cash Costs1 and AISC1 guidance reflect the currently high spot zinc concentrate treatment charges.  Included in 2020 cost guidance is an assumption of $300 per tonne of zinc concentrate. This is up from $250 per tonne of zinc concentrate which was the annual benchmark set for the industry in 2019. For every $30/tonne change (+/-10%) there is an impact to C1 Cash Cost1 and AISC1 of approximately $0.03 per pound of zinc.

While it is Trevali’s view that these historically high spot treatment charges will not subsist for the long term, management has taken a conservative approach and included it in the 2020 cost guidance. Despite this inclusion, the Company is on track to deliver on the T90 Program and reduce AISC1 to $0.90 per pound of zinc by the beginning of 2022.

Quarterly Variability of 2020 Full Year Guidance

  • Production: While production guidance has been provided on an annual basis, we do expect moderate fluctuations on a quarter-to-quarter basis due to mine scheduling. Zinc production overall is forecast to be slightly higher in the second half of 2020 as Caribou and Santander are scheduled to deliver higher production rates relative to the first half of 2020. 
  • Operating costs (“C1 Cash Cost1 and AISC1”): The Company expects costs to begin the year at the higher end of the guided range and trend lower as the year advances as initiatives from the T90 Program are implemented and their benefits are realized in the business.
  • Sustaining and expansionary capital: Quarterly variability of the capital program is not expected to be material. Note that 2020 expansionary capital guidance currently excludes the RP2.0 Expansion Project as timing and costs will be determined and guided as part of the pre-feasibility study to be published by the end of Q1 2020. 
  • Exploration expenditures: The 2020 exploration program will continue to focus on advancing near-mine exploration targets towards the development of new mineral resources located within trucking distance of existing mines, while also maintaining a necessary level of expenditures on regional programs to make new discoveries. Timing of expenditures is contingent on positive exploration results and additional funds beyond guidance may be allocated.

T90 Program

At the end of Q3 2019, Trevali launched the T90 Business Improvement Program which targets $50 million of annual sustainable efficiencies and a reduction in AISC1 to $0.90 per pound of zinc by the beginning of 2022. As of the end of 2019, $42 million in sustainable efficiencies have been identified and $14 million in sustainable efficiencies have been implemented and will be realized on an ongoing annual basis. Highlights of the T90 Program will be discussed in detail in the Q4 2019 and Full Year Results.
