Milestone was awarded a contract to provide labour, materials, and equipment for Phase 2 of remediation at the Atlin Ruffner Mine Site in BC. This phase focused on water management around the adit drainage, tailings pond and sedimentation pond areas. The project also included provisions for establishing permanent access to the site.

The objective of the work was to divert surface water and groundwater around the tailings and sedimentation ponds to minimize interaction between clean water and remnant tailings. The work was completed as per the requirements of the mine closure permit and regulatory requirements.
