Trevali Announces Temporary Suspension of Caribou Mine Operations

March 26, 2020

Vancouver, British Columbia: Trevali Mining Corporation (“Trevali” or the “Company”) (TSX: TV, BVL: TV; OTCQX: TREVF, Frankfurt: 4TI) today announced the temporary suspension of operating activities at its Caribou mine near Bathurst, New Brunswick.

The global zinc market has deteriorated, and this has been exacerbated by the continued challenges presented by COVID-19. These market conditions, combined with high concentrate treatment charges, make mine operations at Caribou uneconomic at this time. The mine will be put on a care and maintenance program immediately to preserve the value of the mineral resource and mine assets. No timeline for a potential restart of operations has been defined. Trevali’s operations centre in Bathurst, which serves the Company’s global mine portfolio, will continue to operate.

Ricus Grimbeek, Trevali’s President and CEO stated, “This is a difficult but necessary decision given the market and operating circumstances. We have a capable and engaged team at Caribou, and in the last 12 months we have made incremental improvements to increase production and reduce the cost structure. During the past year we demonstrated that the Caribou mill can achieve higher throughput than nameplate capacity while at the same time increasing metallurgical recoveries leading to higher production, however the significant recent drop in the zinc price limits our ability to generate positive cash flow. This decision is no reflection on the quality of our team or the operating conditions in New Brunswick, and while the operation is paused, we will study a multitude of options in the Bathurst region to maximize value and reduce the overall cost structure of Caribou. This includes the potential to supplement the Caribou mine ore feed from ore deposits within trucking distance of the Caribou mill, metallurgical opportunities which may lead to commercial benefits around copper and gold, and potential for joint ventures with third parties.”

Added Mr. Grimbeek: “This was not a decision made lightly and we are sensitive to the impact this will have on the community and on our team. We will be providing transition assistance to our workforce in addition to severance. I thank the entire Caribou team for their efforts to enhance the competitive position of the mine.”

One-time costs to place the mine on care and maintenance over the course of April and May are estimated to total approximately US$5 million with the ongoing costs expected to be approximately US$0.5 million per month on a cash basis to ensure that the mine, mill, and associated infrastructure are safe and secure, and positioned to restart efficiently when conditions might allow. The Company will be examining the carrying value of Caribou and will provide an update as part of its Q1 2020 financial and operating results.


Trevali is withdrawing its current 2020 guidance due to the suspension of operations at Caribou as well as the resulting uncertainty caused by COVID-19. Trevali is currently implementing proactive and reactive mitigation measures to minimize any potential impacts COVID-19 may have on our people, communities, operations, supply chain, and finances. This also includes preserving capital and deferring capital programs where appropriate. The Company expects to provide an update on its future outlook in due course.

Aligned with the strategy of preserving capital, Trevali also announced that it has cancelled the Normal Course Issuer Bid ("NCIB") commenced December 2, 2019, as the Company no longer intends to repurchase its common shares. No common shares were purchased by the company under the renewed NCIB, though under the original NCIB in place from November 19, 2018 to November 18, 2019, a total of 28.6 million common shares were repurchased for cancellation.


Trevali is a global base-metals mining company, headquartered in Vancouver, Canada. The bulk of Trevali’s revenue is generated from base-metals mining at its four operational assets: the 90%-owned Perkoa Mine in Burkina Faso, the 90%-owned Rosh Pinah Mine in Namibia, the wholly-owned Caribou Mine in northern New Brunswick, Canada and the wholly-owned Santander Mine in Peru. In addition, Trevali owns the Halfmile and Stratmat Properties and the Restigouche Deposit in New Brunswick, Canada, and the past-producing Ruttan Mine in northern Manitoba, Canada.
