Environmentalists are demanding an immediate halt to exploratory drilling on Catface Mountain, 13 kilometres north of Tofino on the west coast of Vancouver Island.

Selkirk Metals is drilling for copper on an exploratory drilling permit issued by the province, but not reviewed or approved by the local Clayoquot Sound Central Region Board, the group Friends of Clayoquot Sound said Thursday.

The group said the regional board must review all land use decisions in the Clayoquot Sound UNESCO biosphere reserve to ensure First Nations and local community concerns are represented.

Selkirk hopes to develop an open-pit copper and molybdenum mine on Catface Mountain.
