Rio Tinto-owned Diavik Diamond Mine in the Northwest Territories of Canada has reached a significant milestone of producing 150 million carats of rough diamonds since it commenced production in 2003.

Diavik, located on an island in a remote sub-Arctic lake, produces predominantly gem-quality white diamonds and a small quantity of yellow diamonds, destined for high-end jewellery in all major consumer markets around the world.

It is the first diamond mine in Canada to achieve 150 million carats of rough diamond production, surpassing the original expectations in the late 1990s of just over 100 million carats, according to Rio Tinto.

From the beginning, Diavik has set new benchmarks in technology, partnerships and sustainability, with its diamonds revered for their Canadian origin and pure provenance.

Matthew Breen, COO of Diavik, said the milestone is a testament to the focus of the Diavik team and their commitment to safe and effective operations despite challenging operating conditions.

Diavik mine, comprising four pipes, is scheduled to end production in early 2026. Planning for closure has been ongoing throughout the life of Diavik, with closure goals covering safety, land use, landforms, water, biodiversity, community capacity and resource development, revealed Rio Tinto.
