TREVALI BEGINS TRUCKING CONCENTRATE AT CARIBOU MINE

Trevali Mining Corp.'s Caribou mine, located 50 kilometres west of Bathurst, N.B., Canada, has trucked its first ore concentrate on March 30, 2021, since announcing the planned restart of operations on Jan. 15, 2021

On Feb. 10, 2021, Trevali restarted operations at the Caribou mine, which had been on care and maintenance since March, 2020. Since reopening, rehabilitation of the main ramp, underground operating levels and access ways have been completed. Additionally, testing of surface infrastructure, including the mill, was successfully completed.

The first ore was brought to surface and delivered to the stockpile on March 6, 2021. The mill's first 24-hour production period without interruption took place on March 25, 2021. The Caribou operations team plans to process 2,600 to 2,800 tonnes of ore per day for the remainder of 2021 representing 60 million to 65 million pounds of zinc and shipping concentrate at regular intervals throughout the year.

Ricus Grimbeek, president and chief executive officer, noted: "I am proud of the Caribou team for all the work they have put into restarting the mine. The team moved quickly to staff up the operation over the last couple months and get the mine, mill, and other systems and infrastructure into good working order. With this first truckload of concentrate leaving the site, we have achieved a major milestone safely and on schedule. I look forward to the continued safe ramp-up of operations. Thanks to everyone on the team and in the community for their efforts in making this a continuing success."
