The Yukon Water Board has approved a plan that's meant to reduce the risk of a catastrophic tailings spill this spring at the abandoned Mount Nansen mine site in the central territory.
The Little Salmon Carmacks First Nation is warning spring melt could cause the tailings dam at the abandoned Mount Nansen mine in central Yukon to overflow or breach, which would send a toxic slurry into the environment.
In court documents, the company is accused of storing hazardous materials in a manner contrary to an approved management plan between April 19, 2022, and July 25, 2023, a violation of its quartz mining licence.
