Copper North Mining Corp. (TSX.V:COL) is a Canadian mining exploration and development company, spun out from Western Copper Corporation (TSX:WRN) in October 2011. Copper North's key asset is the Carmacks Copper Project, located in the Yukon Territory, Canada. Carmacks is permitted for construction and will produce 30 million pounds of cathode copper per year. The project is being re-engineered as a copper-gold-silver leach operation. A Preliminary Economic Assessment was completed in May 2014 and indicates that the addition of gold and silver recovery provides a positive improvement in project economics. A second phase of engineering work is in progress to evaluate opportunities to further improve operations and reduce capital and operating costs. The company resumed exploration in 2014 and 2015 leading to a substantial increase in oxide and sulphide resources, with the potential to extend mine life.
