The Project
The Casino Mine Project, a proposed open-pit copper-gold-molybdenum mine located 300km northwest of Whitehorse in Yukon Territory, encompasses comprehensive facilities, including a heap leach facility for gold extraction, a processing mill for copper and molybdenum concentrates, and a tailings and waste rock management facility. Due to predicted elevated levels of cadmium, copper, uranium, zinc, selenium, and sulphate in water from the tailings management facility pond and open pit, Casino Mining Corp engaged True Environmental to investigate treatment options. Through a systematic approach involving site assessment, bench-scale testing, and off-site pilot-scale testing conducted from November 2016 to July 2017, True Environmental evaluated the efficacy of constructed wetlands treatment systems (CWTS) as a passive/semi-passive water treatment solution.
The pilot testing, which simulated various hydraulic retention times and predicted water chemistry conditions, successfully demonstrated that CWTS could achieve outflow concentrations meeting Canadian Council of Ministers of the Environment guidelines, with confirmed sequestration of contaminants in stable soil forms and verified cold climate treatment mechanisms, ultimately establishing CWTS as a viable closure water treatment technology for the project
