Diavik Diamond Mine Closure in Northwest Territories Involves Extensive Remediation Efforts
Gord Stephenson oversees the closure of the Diavik diamond mine, which involves remediation and monitoring efforts lasting over a decade. After mining ends, the site will undergo three to four years of cleanup, with some materials repurposed and hazardous waste transported for disposal. The closure poses economic challenges for NWT, where diamond mining contributed $1.2 billion to GDP. Premier R. J. Simpson suggests future opportunities in critical minerals may sustain the economy.
The Diavik diamond mine in Northwest Territories is set for closure, which will require extensive remediation. Gord Stephenson is managing the process that transforms the mine back into an untouched landscape, with cleanup efforts projected to last three to four years, followed by ten years of monitoring.
The site will see processed kimberlite fill craters, and some materials may be repurposed. The closure is economically significant for NWT, where diamond mining has contributed $1.2 billion to GDP. The territory anticipates potential opportunities in critical minerals to support its economy post-mining.
