Rock Lake Mine South Rehabilitation Project

Proposal details: The Rock Lake Mine (AMIS #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 southern portion of the Rock Lake Mine property. The rehabilitation work will focus on an adit feature that provides access to the underground workings and is easily accessible by the public. The adit is accessed by a residential driveway off Highway 638. Limited site access improvements are needed to facilitate the work. The boundary of the project area is defined by the access road and the area east of the adit. All other hazards associated with the Rock Lake Mine are primarily situated in the northern portion of the property and will be included as part of a separate Class Environmental Assessment.

It is assumed that the underground workings provide habitat to bat species at risk and, as such the preferred rehabilitation strategy is the installation of a stainless-steel gate. The gate will eliminate safety concerns related to access by the public, while still allowing bats to easily enter/exit the underground workings. The work is expected to occur over five days, during the summer months (i.e., between May 1st and October 31st) when bats are not expected to be actively hibernating within the mine.
