Mining Licences

What Are Mining and Exploration Licences?

Ring of Fire mining licences and exploration licences are official legal approvals required to extract natural resources at mining sites, operate facilities, transport dangerous goods, and manage emissions.

They are granted by government agencies that allow companies to carry out regulated activities such as storing explosives, harvesting timber, extracting aggregates, or operating facilities related to mining projects.
Licences differ from permits in that they often apply to ongoing operations, material handling, and the use of natural resources.

Discharge of industrial wastewater or emissions

Along with mining claims, obtaining the appropriate mining licences ensures compliance with federal and provincial laws, protects public safety, and supports environmental stewardship.
