Since achieving its first commercial production in April of 1997, Musselwhite mine has produced over three million ounces of gold. For 2015, gold production totaled 270,300 ounces.
A key target of 2016 exploration efforts will be extending the West Limb, where six mineralized horizons have been established. Exploration in 2016 will also follow-up on the Upper Lynx zone where two mineral horizons are both open to the north for further expansion.
On July 27, 2016 the board approved the Materials Handling Project at Musselwhite. Currently, mining is at a depth below 1,000 metres under Lake Opapimiskan and the truck haulage distance is 7.5 km to the 400 mL underground crusher. This growth has resulted in a haul truck fleet size of 17 haul trucks, necessitating a more economical and practical means of transporting ore as the current ventilation system cannot support the additional haul truck fleet required to extend mine life. The project will enable hoisting of ore through an underground winze and associated infrastructure which will result in reduced reliance on high-cost truck haulage by significantly reducing uphill truck haulage between the winze and underground crushers leading to improved energy efficiency, reduced ventilation requirements, reduced mining costs, enhanced production profile and potential to extend mine life through exploration success.
Following completion of the winze, which is expected in the first quarter of 2019, incremental production of approximately 20% is anticipated and operating costs are expected to be reduced by approximately 10% for the life of the mine.
