The Gahcho Kué diamond mine in the Northwest Territories reported a net loss of $120.6 million in the second quarter of 2026, as disclosed by Mountain Province Diamonds, one of its co-owners, in a recent press release. Mountain Province Diamonds holds a 49% interest in the mine, while De Beers Canada owns the remaining stake. In comparison, the mine recorded a net loss of $65.1 million in the first quarter of 2026 and a total net loss of approximately $280 million in 2025. Notably, Gahcho Kué is the sole operational diamond mine in Canada.
The challenging scenario in the diamond market persists for producers, amidst factors like U.S. tariffs causing geopolitical and economic uncertainty. Nevertheless, despite the financial setback, Jonathan Comerford, the President and CEO, noted a positive development in diamond prices during the latest diamond sale, crediting the improvement to a reduction in the global diamond supply. Comerford cautiously expressed optimism, stating that while it is premature to confirm a sustained market upturn, the recent sale results were promising.
The global diamond industry has witnessed a trend of closures or temporary halts in operations at several mines due to unfavorable market conditions. For instance, the Ekati Mine in the N.W.T. recently entered receivership after being supported by federal loans for some time. This shrinking supply landscape may potentially benefit surviving mines like Gahcho Kué.
According to Paul Zimnisky, an independent analyst in the diamond sector, around ten major diamond mines worldwide have ceased operations or suspended production, marking a significant decline in diamond output this year. Notably, higher-quality diamonds have displayed better market performance over the past year, but recently, lower-demand diamond categories have shown improved performance, likely influenced by the reduced supply.
While positive signs in the supply chain have emerged, Zimnisky cautioned that a substantial recovery in diamond prices necessitates an increase in demand. Historically, De Beers’ role in financing diamond marketing has been pivotal in driving demand. Zimnisky highlighted the importance of marketing, especially for luxury goods like diamonds, where consumer emotions heavily influence demand. He emphasized the need for a new demand catalyst to drive diamond prices to desired levels, foreseeing stable pricing trends in the near term.
