Diavik Diamond Mine

Diavik Diamond Mine is a large diamond mine situated on an island in Lac de Gras, in Canada's Northwest Territories, within the Arctic Circle. The operation was developed as an open-pit and later underground mine, extracting kimberlite ore bodies rich in gem-quality diamonds. It is majority owned and operated by Rio Tinto, the multinational mining group, with Dominion Diamond Mines previously holding a minority stake. The mine ranks among the world's most significant diamond producers, supplying rough stones to the global jewellery and industrial-diamond markets. Its remote location demands specialised logistics, including ice roads and air transport, and heavy reliance on diesel power generation historically, with efforts since made to incorporate renewable energy such as wind power to reduce emissions. The site uses large fleets of mining equipment, including haul trucks and loaders supplied by manufacturers such as Caterpillar, alongside pumps and processing equipment from companies like Weir. Diavik has featured in industry discussions on critical minerals and sustainable mining practices in harsh environments. The mine began production in the early 2000s and has operated for more than two decades, becoming a benchmark for Arctic resource extraction. It has faced a planned transition towards closure as its kimberlite pipes near depletion, prompting attention to environmental rehabilitation. The mine remains a reference point in coverage of responsible mining and technology adoption in extreme climates.
