N.W.T.'s Gahcho Kué diamond mine marks grand opening

Just over two decades in the making, Canada's newest diamond mine is set to officially open Tuesday in the N.W.T. at a ceremony involving Indigenous leaders, mining and territorial officials.

The Gahcho Kué mine, located on the tundra about 280 kilometres northeast of Yellowknife, is estimated to be one of the 10 biggest diamond mines in the world.

De Beers predicts that over the mine's expected 12-year life span, Gahcho Kué will inject about $6.7 billion into the Canadian economy, with a significant portion of that landing in the N.W.T.

The company says it has already invested about $1 billion in developing the mine, with about $440 million going directly into the N.W.T. economy. Another $4 million has been paid to the six aboriginal groups that signed impact and benefits agreements.
