Mount Polley Copper/Gold Mine

Mount Polley is an open pit copper/gold mine with an underground component located in south-central British Columbia, 56 kilometres northeast of Williams Lake.

About This Project

Mount Polley mine is owned and operated by Mount Polley Mining Corporation (MPMC), a subsidiary of Imperial.

The Mount Polley mine resumed normal operations in June 2016, following receipt of authorizations from the Ministry of Energy and Mines (MEM) and the Ministry of Environment (MOE). To date, significant progress has been made with the rehabilitation of the areas impacted by the 2014 Mount Polley Breach. Research and monitoring has observed rapid recovery of the impacted environment. The rehabilitation work and monitoring of these areas is ongoing.

Mining in the Cariboo pit will be completed in mid-2018, and the mine will then rely on stockpiled ore to provide mill feed for the balance of 2018. Approximately 5 million tonnes of mill tailings were stored in the Springer pit following the resumption of operations in 2015. To remove the tailings from the Springer pit and gain access to the ore beneath, a dredge is being mobilized to pump the tailings from the pit to the repaired and buttressed tailings facility. It is expected for this to be complete by early 2019.
