Board approves 4th diamond mine in Canada’s Northwest Territories
A review board in Canada’s Northwest Territories has approved the regions proposed fourth diamond mine in a report released Friday.
The Mackenzie Valley Environmental Impact Review Board recommended De Beers’s Gahcho Kue Diamond Project proceed, but with a number of conditions.
De Beers and Mountain Province Diamonds want to build a large open-pit diamond mine at Kennady Lake about 280 kilometres northeast of the territorial capital of Yellowknife.
The panel that reviewed the project said Gahcho Kue is likely to cause significant adverse impacts on the Bathurst caribou herd unless measures are taken to protect it.
Those measures would include:
- developing a caribou and caribou habitat protection plan prior to mine construction
- keeping the mine’s footprint as small as possible
- building and operating the winter road to the mine in a way that will minimize impacts on caribou
- developing a monitoring plan to determine what effects the road and the mine are having on caribou
The review panel is also calling on the federal and territorial governments to develop a framework to measure the effects Gahcho Kue is going to have on caribou in combination with other mining projects in the area.
The proposed mine is located not far from De Beers’s other Northwest Territories diamond mine, Snap Lake. Mountain Province owns 49 per cent of project; De Beers 51 per cent.
With the Ekati and Diavik diamond mines winding down their mine lives, the NWT/Nunavut Chamber of Mines says now is the time to begin work on a new diamond mine.
“We need to have projects in the queue that can start to take the place of the ones that close,” said Tom Hoefer. “We need to be starting now.”
Gahcho Kue would be a smaller mine with a shorter lifespan.
To get at the diamonds, De Beers and Mountain Province Diamonds propose to drain the southern part of Kennady Lake.
Steve Nitah with the Lutselk’e First Nation said he worries about the environmental impacts to fish habitat and migrating caribou.
“Such a huge footprint for such a short mining life,” he said. “What can the long term benefits really be?”
The federal government will have the final say if the mine is approved to go ahead.
