Rock Lake Mine North Rehabilitation Project

Proposal details:

The Rock Lake Mine (AMIS number 07781) is a former gold, silver and copper mine that operated from 1899 to 1903. The mine property is divided into a northern area accessed by a private trail and a southern area accessed via a residential driveway.

The objective of the project is to rehabilitate the mine hazards located in the northern portion of the Rock Lake Mine property. The hazards include a shaft, two raises, a stope to surface, and multiple crown pillars. The mine openings to surface are all currently flooded with no egress provided. The Rock Lake North Mine is situated on private land held by a surface rights owner.

The proposed rehabilitation strategy for all mine workings is backfill. Access will be provided by an existing roadway off Highway 638, with limited access improvements required. Some tree removal may be needed to facilitate the placement of the backfill. The work is expected to occur over several months, during the fall of 2025, outside of the active period for bats and birds.
