Lynn Lake Gold Project

Alamos Gold Inc. is proposing the construction, operation, decommissioning, and reclamation of an open pit gold mine and new metal mill located approximately 1000 kilometres north of Winnipeg, near Lynn Lake, Manitoba. The Lynn Lake Gold Project would involve the redevelopment of two historical gold mines (the Gordon site and MacLellan site) and have an ore input capacity of 8,000 tonnes per day over an 13-year period. Components of the project would include new mine infrastructure, open pits, an access road, a central ore milling and processing plant, ore stockpiles and mine rock storage areas, and a tailings management facility.
