  • Replace and Expand Underground Resources: Underground drilling for reserve, resource, and inventory definition to support production and growth (38,000 metres).
  • Identify Satellite Deposits:Near-mine surface drilling to evaluate targets for potential shallow open-pit satellite deposits within a 10 km-radius of the mill (6,500 metres).

Our Community

Maintaining strong First Nations partnerships with the Indigenous Communities, governments and businesses where we operate are paramount to the success of the Musselwhite operation. We strive to create lasting positive change by supporting the economic and social well-being of our host communities. Our goal is to make sure the benefits continue well beyond the life of the mine, while keeping our impacts to a minimum. By working together, we aim to foster trust and cultivate a genuine, positive relationship between the company and the community.
