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. The property encompasses 19,601 hectares, comprised of seven mining leases totalling 2,007 hectares, and 45 mineral claims encompassing 17,594 hectares. Mount Polley mine is owned and operated by Mount Polley Mining Corporation (MPMC), a subsidiary of Imperial.
Following the temporary suspension of operations on August 4, 2014 due to the breach of the tailings dam, modified mine operations were restarted on August 5, 2015. MPMC received further authorizations from the BC Ministry of Energy and Mines (MEM) and the Ministry of Environment (MOE) on June 23, 2016 which consented the mine’s return to normal operations utilizing the repaired and buttressed tailings storage facility. Since 2014 significant rehabilitation of the areas impacted by the breach has been completed. Instream work required to create fish habitat was also completed on approximately one kilometre in the upper portion of Hazeltine Creek below Polley Lake. Additional necessary rehabilitation and monitoring of these areas will continue. Research and monitoring to date indicates the environment is recovering rapidly.
Mining activity in 2016 was focused in the Cariboo pit and the Boundary zone underground workings. The underground development to allow diamond drilling on the Martel Zone, was completed in 2016, following which a 5,000 metre underground drill program was initiated. The goal of the program is to confirm a higher grade mineable block within the previously defined resource of 6.26 million tonnes grading 1.17% copper and 0.40 g/t gold.
The 2017 production target for Mount Polley is 26-29 million pounds copper and 55-60 thousand ounces gold. All 2017 production is expected to come from open pit operations.
