Main Assets

Trevali has four revenue generating properties located in Namibia, Canada Peru and Burkina Faso

The Rosh Pinah mine is an underground zinc-lead mine and 2,000 tonne per day milling operation located in southwestern Namibia, at the edge of the Namib Desert, and has been in continuous operation since 1969 and currently produces zinc and lead sulphide concentrates containing minor amounts of copper, silver and gold. Rosh Pinah just announced its feasibility study for the RP2.0 expansion, which is expected to increase the throughput of the mine from 0.7 million tpa to 1.3 million tpa and produce zinc for a cash cost of US$0.63 per pound of payable zinc and AISC of US$0.72 per pound of payable zinc.

The Rosh Pinah mine is 90% owned by Trevali and 10% by Namibian Broad-Based Empowerment Groupings and an Employee Empowerment Participation Scheme (EEPS).

The Company’s wholly owned zinc-copper-lead-silver-gold Caribou mine is located 50 km west of Bathurst, New Brunswick, Canada. The operations consist of an underground mine with significant underground development, a fully permitted 3,000 tpd mill, a sulphide flotation recovery plant, metallurgical and geochemical laboratories, a tailings management facility, and other associated infrastructure. On August 3, 2021 Trevali announced a pilot plant testing program using ROL technology that if successful has the potential to allow Trevali to replace the existing flotation circuit at Caribou with atmospheric leach vessels and potentially an SX/EW train, introducing the possibility of producing base and precious metals on-site and thereby save transport costs and offsite treatment costs.
