Copper Mountain is 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 to expansion in many areas, particularly at depth.
The mineral processing facility was designed to process 35,000 tpd and with the addition of a secondary crusher is now targeting up to 40,000 tpd. Metallurgical recoveries in the mill range between 79% and 92% depending on the mining location, with an average annual recovery of approximately 84%.
Sandstorm’s royalty covers a portion of the Copper Mountain claims, including the Alabama and Virginia deposits. Ore is not currently being mined from Sandstorm’s royalty ground.
Copper Mountain announced the results from the Preliminary Economic Assessment for the New Ingerbelle deposit, located one kilometer from the Copper Mountain mine. Sandstorm’s royalty does not cover the Ingerbelle deposit.
Mining activities were focused on the Pit#2 and Virginia pit areas during 2016. Copper Mountain is no longer producing from the Virginia pit.
