Musselwhite: Increasing Productivity and Underground Development

  • Musselwhite was one of the first mines in Canada to enter into a comprehensive agreement with First Nations communities when the Musselwhite Agreement was signed in 1992. In 2014, the Mishkeegogamang Agreement was signed.
  • In the fourth quarter of 2020, Musselwhite implemented a new conveyor system and material handling systems, improving material movement from its two main zones below Opapimiskan Lake. The underground shaft hoists ore from the underground crushers, reducing haulage distances and ventilation costs.
