Yukon mine in 2024 failure will discharge treated water in preparation for snow melt
The Eagle Gold Mine in Yukon had a catastrophic heap leach failure in June 2024, spilling about two million tonnes of cyanide-soaked ore that contaminated local groundwater.
The Yukon government says that ditches, culverts, and pumping systems have been set up to divert spring runoff from cyanide-contaminated water onsite.
Storage ponds at the mine have about 315,000 cubic metres of storage capacity to handle expected influxes of water from the spring snowmelt.
Since April 2025, interception wells have captured over 670,000 cubic metres of cyanide-containing water for treatment, and the receiver is recovering gold from this water to fund site remediation while seeking a new buyer.
