The McCreedy West Mine was first developed by Inco in 1970 and operated until1998, when it was closed. KGHM International began work on the McCreedy West property in 2002. Exploration efforts on the property resulted in the discovery of the contact nickel Inter Main Deposit in 2002, which has been in production since 2003. The company closed McCreedy West in October 2015 due to low nickel prices. Nickel production will end in 2016, with mining from Morrison to continue thereafter, producing copper concentrate only.
