Trevali Reports 2021 Mineral Reserves and Resources Including a 50% Increase to Mineral Reserves at Rosh Pinah

Canada NewsWire

VANCOUVER, BC, March 31, 2022 /CNW/ – Trevali Mining Corporation (“Trevali” or the “Company”) (TSX: TV) (BVL: TV) (OTCQX: TREVF) (Frankfurt: 4TI) reports its Mineral Reserves and Mineral Resources statements as of December 31, 2021.

“We are pleased to announce a 4.9 million tonne increase in our consolidated Proven and Probable Mineral Reserves, which is a 28% increase over the year ended 2020,” said Ricus Grimbeek, President and CEO. “Through the dedicated efforts of the team our flagship operation, Rosh Pinah, contributed significantly to this achievement by increasing its Mineral Reserves by 50% year over year, and also represents a 36% increase to the Rosh Pinah Expansion RP2.0 Feasibility Study published in August 2021. This is a great result as it adds 4.39 million tonnes to the existing 12.35 million tonnes of Mineral Reserves reported in that study and is expected to extend the mine life beyond 2032. With the RP2.0 early works program underway we view Mineral Resource and Reserve expansion as an effective and efficient way to create value for shareholders.”

The increase in Mineral Reserves at Rosh Pinah comes predominantly from the conversion of existing Mineral Resources through the following two factors: first, the infill drilling program at the Eastern and the AAB Orefields; second, the expected change to the mining method with the inclusion of paste backfill as outlined in the Rosh Pinah Expansion RP2.0 Feasibility Study, which is anticipated to lead to higher mining recoveries.

Highlights
  • Consolidated Proven and Probable Mineral Reserves of:
    • 2.9 billion pounds of contained zinc;
    • 676 million pounds of contained lead; and,
    • 19.9 million ounces of contained silver.
    • Increase in tonnage by 4.9 million tonnes and contained metal by 450 million lbs zinc is due to conversion drilling and engineering work at Rosh Pinah partially offset by mining depletion at Perkoa.
  • Consolidated Measured and Indicated Mineral Resources of:
    • 7.5 billion pounds of contained zinc;
    • 2.1 million pounds of contained lead; and,
    • 63.2 million ounces of contained silver.
    • Successfully replaced due to exploration and expansion drilling, with an increase at Rosh Pinah offsetting decreases at the Perkoa and Caribou Mines.
  • Rosh Pinah Mineral Reserves of:
    • 2.1 billion pounds of contained zinc – an increase of 44.6%;
    • 466 million pounds of contained lead – an increase of 46.0%; and,
    • 10.6 million ounces of contained silver – an increase of 39.8%.
    • Increase in tonnage by 50% from the Company’s December 31, 2020 statement, from 11.2 million tonnes to 16.7 million tonnes.
  • Perkoa Mineral Reserves decreased due to mining depletion and limited conversion of Mineral Resources to Mineral Reserves. While the Company is doing work to evaluate the cost structure of the operation in the current zinc price environment, it is not currently anticipated that there will be a material conversion of existing Measured and Indicated Mineral Resources. Exploration efforts continue.
  • Caribou Mineral Reserves modestly decreased as mining depletion was only partially offset by an increase in Net Smelter Return (NSR) values driven by higher metal prices.
Consolidated Mineral Reserves and Mineral Resources Statement

Consolidated Mineral Reserves and Mineral Resources statements are summarized in Tables 1 to 3, while detailed breakdowns for each of the mines and projects are provided in the detailed section. Mineral Resources in this document are reported inclusive of Mineral Reserves.

Detailed Mineral Reserve and Mineral Resource Disclosure
Rosh Pinah Mine

The conversion drilling program, along with increasing NSR values and higher mining recoveries, successfully replaced and exceeded the 2021 mining depletion, resulting in a 50% increase in tonnage in Proven and Probable Mineral Reserves compared to the 2020 year-end Mineral Reserves disclosure. The Mineral Reserve zinc grade is modestly lower than the 2020 year-end disclosure, the decline occurred primarily due to a combination of factors including mining higher than average Mineral Reserves grade tonnes in 2021, as well as adding lower grade tonnage along the Eastern Orefield and at the AAB deposit.

The Rosh Pinah Expansion “RP2.0” Feasibility Study, which focused on evaluating an expansion scenario to the Rosh Pinah concentrator and a change of mining method to paste back fill, was completed in 2021 and contributed significantly to the conversion rate of Measured and Indicated Mineral Resource to Proven and Probable Mineral Reserves. Approximately 50% of the increase in Mineral Reserves can be attributed to the change in mining method along with higher NSR values associated with higher metal prices. The remaining increase in Mineral Reserves was the result of Mineral Resources conversion mainly at the Eastern Orefield and the AAB Orefield.

Perkoa Mine

The annual Mineral Reserve statement for the Perkoa mine utilized a net smelter return cut-off-value of US$90 per tonne, which is a decrease of $10 in comparison to the 2020 year-end disclosure. The Mineral Resources are disclosed using a 5% ZnEQ cut-off value which is the same value used as previous years. The 2021 mine production at Perkoa resulted in a net mining depletion of 0.70 million tonnes. Mineral Reserves decreased by 0.57 million tonnes year on year, which is less than the 2021 mining depletion, and is the result of higher NSR values associated with higher metal prices.

While the Company is doing work to evaluate the cost structure of the operation in the current zinc price environment and continuing exploration, it is not currently anticipated that there will be a material conversion of existing Measured and Indicated Mineral Resources to Mineral Reserves in 2022.

Caribou Mine – Bathurst Mining Camp Operations

The annual Mineral Reserve statement for the Caribou mine utilized a net smelter return cut-off-value of US$80 per tonne, which represents a $5 per tonne increase over the 2020 year-end cut-off. Proven and Probable Mineral Reserves tonnage decreased slightly from 2020 mainly due to mining depletion which was minimized by higher NSR values driven by higher metal prices. The overall Mineral Reserve grade decreased slightly due to the inclusion of lower grade material in the Mineral Reserves due to the higher NSR values.

Qualified Persons and Technical Information

The Mineral Reserve and Mineral Resource estimates have been estimated and compiled in accordance with definitions and guidelines set out in the Definition Standards for Mineral Resources and Mineral Reserves adopted by the Canadian Institute of Mining, Metallurgy, and Petroleum and as required by Canada’s National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources at Trevali’s material properties, as well as data verification procedures and a general discussion of the extent to which the estimates of scientific and technical information may be affected by any known environmental, permitting, legal title, taxation, sociopolitical, marketing or other relevant factors, please see the technical reports for the company’s material properties as filed by Trevali on SEDAR at www.sedar.com.

The Mineral Reserve and Mineral Resource estimates were prepared under the supervision of Yan Bourassa (M.Sc., P.Geo.), Trevali’s Vice President of Technical Services & Exploration. Mr. Bourassa is a Qualified Person as defined by NI 43-101.

Notice to United States Investors

Unless otherwise indicated, all mineral resource and mineral reserve estimates included in this press release have been prepared in accordance with NI 43-101, and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 contains the rules and codes of practice developed by the Canadian Securities Administrators that established minimum standards for all public disclosure of scientific and technical information an issuer makes concerning mineral projects. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These definitions differ materially from the definitions in the U.S. Securities and Exchange Commission (“SEC”) Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Exchange Act of 1934, as amended. Under the SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves, and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into reserves. Actual recoveries of mineral products may differ from reported mineral reserve and mineral resource estimates due to inherent uncertainties in acceptable estimating techniques. In particular, inferred mineral resources have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in very limited circumstances. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of “contained metal” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures. Mineral resources may be affected by further infill and exploration drilling that may result in increases or decreases in subsequent resource estimates. Mineral resources may also be affected by subsequent assessments of mining, environmental, processing, permitting, taxation, socio-economic, and other factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Investors are cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into proven and probable mineral reserves. For the above reasons, information contained in this news release containing descriptions of the Company’s mineral deposits may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
