First in-situ recovery (ISR) uranium mine in Canada to set new standard for sustainability.
Janna Switzer, director of health, safety, environment and regulatory compliance at Denison, is enthusiastic about introducing the ISR method to Saskatchewan uranium mining. “Traditional mining methods can have workers travel to depths of 500 metres underground,” says Switzer. “With ISR, all operations are done at the surface. That’s a key health and safety factor.”
“Using the ISR mining method means that we will not require a conventional tailings facility,” explains Switzer, “because we didn’t remove the rocks containing the uranium to process them on surface. Instead, we dissolve the uranium where it is underground and we don’t have to dispose of all of the other waste. We also don’t have to de-water underground mine workings, so we are also expecting to treat and release a much smaller amount of water to operate the site.
After that, Switzer says, “From a regulatory perspective, it’s expected to be about a two- to three-year process to address the comments, finalize an environmental impact statement, and submit the document to the provincial Minister of the Environment and the CNSC.”Article content
