Kudz Ze Kayah is an open-pit and underground silver, copper, gold, lead and zinc mine development located approximately 115 kilometres southeast of Ross River, Yukon and 5 km west of the Wolverine zinc mine.
The project is anticipated to inject up to C$720 million in capital expenditures into Canadian and Yukon economies over its life, Natural Resources Canada said.
The project can now proceed to the regulatory phase.
One of the additional conditions in the environmental decision document includes the establishment of a "Finlayson Caribou Herd Oversight Committee" with representation from Kaska First Nations to provide input into the next phases of the project.
The Canadian government is makling critical minerals development a central piece if its mining policy.
