NEW BRUNSWICK – Trevali Mining Corp. of Vancouver has begun the mill commissioning process at its 3,000-t/d Caribou zinc mine in the Bathurst Mining Camp. The company replaced, repaired or refurbished all key mill circuits in preparation for production.

Initially the mill will treat low grade material in the grinding and flotation circuits until they are operating as designed. Production of zinc and lead-silver concentrates will be a priority. The copper circuit will be commissioned later this year.

A surface stockpile of 75,000 tonnes of ore mucked from underground is available for mill commissioning. An additional 28,000 tonnes has been drilled and is ready for blasting and mucking when needed.

In July or August, Trevali plans to send its senior metallurgical consultant to site, and Glencore has offered to make Isa Mill specialists available if Trevali so desires.

Caribou concentrates will be tolled at the nearby Belledune smelter belonging to Glencore.
