Mountain Province Posts Record 2.0M-Carat Q1 but C$65M Net Loss as Realized Price Falls to $47/ct

Executive Summary

Mountain Province Diamonds, 49% partner with De Beers in Canada's Gahcho Kué mine, reported record Q1 2026 production of more than 2.0 million carats, a 163% year-over-year increase driven by recovered grade of 2.64 carats per tonne, up 222%. The volume gain was outweighed by sharp price pressure: 858,000 carats sold for C$40.0 million (US$29.2 million), an average realized price of US$47 per carat versus $103 in Q1 2025. The company reported a loss from mine operations of C$36.2 million and a net loss of C$65.1 million (C$0.31 per share), with negative adjusted EBITDA. The size-mix issue is the central problem: smaller stones, which face the steepest market pressure, made up a higher share of the recovered output, suppressing average value despite the throughput gain. Liquidity has tightened. The company sold US$999,999 of future receivables from diamond sales to long-time backer Dermot Desmond on May 1 and extended a credit facility. Management is now reviewing strategic alternatives. The result highlights Gahcho Kué's exposure to a market where higher volume cannot offset sub-$50/ct realized prices, and adds another distressed Canadian operator to the May news cycle alongside Ekati.

Industry Impact

Mountain Province's quarter is a real-time stress test of the small-stone segment, showing that even record output cannot rescue cash flow when realized prices halve. As 51% operator of Gahcho Kué, De Beers may face partner-financing questions and reputational pressure if Mountain Province requires an equity rescue. Sightholders and rough traders should consider sub-$50/ct realized prices as a possible floor scenario for melee-heavy mines. Polished manufacturers that rely on small and melee goods should expect continued supply availability, and pricing weakness, into H2 2026.

Next Steps

1. Recalibrate small-stone (≤0.10ct) sourcing forecasts; expect continued supply at depressed prices.
2. Watch for Mountain Province strategic-alternatives disclosure (sale, recapitalization, JV restructuring) in the next 30–60 days.
3. Pressure-test melee inventory carrying costs against a $40–50/ct realized-price assumption.
4. Monitor De Beers commentary on Gahcho Kué partner financing in the next Anglo American operational update.
5. Track Dermot Desmond filings for additional Mountain Province funding signals.
6. Reassess marketing claims that link Canadian origin to scarcity, given the record Q1 volume.
