Copper Mountain mine contains a porphyry copper-gold system located in British Columbia, 180 km east of Vancouver. The mine initiated production in August 2011 and uses truck and shovel open pit mining methods.
A majority of the copper-gold mineralization at Copper Mountain occurs in veins, fracture fillings and disseminations within volcanic rocks of the Nicola Group. Mineralization remains open for expansion in many areas, particularly at depth.
The mineral processing facility was initially designed to process 35,000 tpd, however with the addition of a secondary crusher production capacity is now estimated up to 40,000 tpd. A December 2020 technical report was filed proposing a mill expansion that would be capable of processing 65,000 tpd. The process recoveries will range from 80% for copper, 65% for gold, and 70% for silver.
Sandstorm’s royalty covers a portion of the Copper Mountain claims, including the Alabama and Virginia deposits.
