Ekati goes dark: Canada's first diamond mine finds no buyer

§1No buyer came, so the court did.

The order arrived with none of the ceremony that attended the mine's opening. On July 14, a British Columbia court approved a receivership for the Ekati diamond mine at the request of the Northwest Territories government, appointing PricewaterhouseCoopers to wind the operation down. Production is expected to stop by mid-August, after which a roughly five-week closure sequence hands the site over to reclamation. Ekati was Canada's first diamond mine when it opened in 1998; nearly three decades later, it will be the country's most consequential diamond closure.

The arithmetic of the final weeks was unforgiving. Owner Burgundy Diamond Mines had operated under court protection since May, while an eight-week search for a buyer or fresh investment came up empty. Ottawa had already extended roughly C$185 million in loans, and a further C$50 million made available in May was never drawn because no viable bid materialized to anchor it.

By July 10 the mine held about C$14 million in cash and was expected to exhaust it within days. Its last diamond sale brought in C$27.4 million, two million short of projections. When the money and the bidders both failed to appear, receivership was the only door left.

§2Three hundred and forty people, last in line.

The human ledger is harder reading. Ekati employed about 340 people as of March, down from 700 employees and 542 contractors as recently as 2024. Court filings set aside C$3.5 million for accrued vacation pay and C$2.1 million for a final payroll, and the receiver holds broad authority to conduct layoffs without the notice ordinarily required under the Canada Labour Code. Union of Northern Workers president Gayla Thunstrom warned that "workers' severance is at the bottom of the creditor payment list."

One protection did survive the filing: just over C$326 million in environmental security is shielded from creditor claims, ring-fencing the site's cleanup.

§3The safest supply just got a closing date.

Nothing about the failure was unique to Ekati. Natural diamond demand has been ground down by lab-grown alternatives, tariff friction, geopolitical tension and a prolonged slump in Chinese buying, and prices for the mine's run-of-mine production never recovered enough to carry its costs. Burgundy chief executive Jeremy King called the mine's role in the territory an extraordinary contribution across more than 25 years, and the description is fair: for a generation Ekati anchored an industry that made the NWT the world's third-largest diamond producer by value and made Canadian origin a brand of its own.

What closes with the gates is supply the market had long counted as safe. Canadian goods commanded a provenance premium precisely because they carried none of the questions attached to other origins, and Ekati's carats fed that pipeline for 28 years. With the territory's remaining mines working against their own depletion clocks, the majority of Canada's diamond output now has a visible end date, and the trade's provenance-conscious buyers, from Tiffany to the Canadamark program's licensees, will be bidding for a shrinking pool.
