Mining activity at the Whitehorse Copper Mine has resulted in a disturbed land area of approximately 800 acres. Within this area there are about 53 acres with active slope instability and subsidence associated with the mine and underground workings. The mine is located within the city limits of Whitehorse, about six miles from the city centre. Although the mine has been decommissioned to a level acceptable to the mine inspector, there is still some concern for public safety. In addition, the current decommissioning plan is expected to result in the permanent loss of useful land from within the city limits. This report presents an assessment of the site conditions and options for reclamation to address these concerns.
