Mountain Province agrees 49% Gahcho Kué transfer to De Beers, subject to completion
JEWEL DAILYThe restructuring would give De Beers full ownership of Gahcho Kué while preserving a route for Mountain Province to return. Its significance for rough-diamond supply depends on completion, future funding and mine plans.
Ownership would change on completion
Mountain Province Diamonds announced a restructuring agreement on 1 October 2026 with De Beers Canada, lender Dunebridge Worldwide and its senior secured noteholders. Its wholly owned subsidiary, 2435386 Ontario Inc. (JVCo), would transfer its 49% interest in Gahcho Kué, in Canada’s Northwest Territories, to De Beers, which already holds 51%.
De Beers would become the sole owner when the transaction completes. No subsequent completion notice was found in the public announcements checked through 5 October; the release gives no closing date.
Debt relief has a defined scope
The transfer would settle remaining reclamation payments and debts owed to De Beers under specified joint-venture and payment agreements. On completion, related obligations, guarantees and accrued interest would be released, and specified agreements terminated. The announcement does not establish that every Mountain Province debt disappears or disclose a monetary transaction value.
Dunebridge and the noteholders also agreed to suspend interest and principal repayments and the exercise of specified rights for six months. The release does not specify that period’s start and end dates.
A possible route back to 49%
JVCo would have an option to repurchase the same 49% interest before 31 December 2029. The stated price is the decommissioning-cost share attributable to that interest; no cash amount is given. Separately, first-offer and first-refusal rights would apply if De Beers later chose to sell all or substantially all of the mine or its mineral rights.
Those provisions preserve possibilities for future participation. Exercising them would still require the relevant circumstances and funding; the announcement provides no guarantee of a return.
Production and selling prices tell different stories
For the quarter ended 30 June 2026, Gahcho Kué recovered 2,014,563 carats on a whole-mine basis, against 708,072 a year earlier. Separately, Mountain Province sold 869,520 carats for C$43.5 million, averaging C$50 per carat, compared with C$90 in Q2 2025.
The sales figures concern the company, not the entire mine. Average realised prices also reflect the assortment sold and are not a like-for-like diamond price index. Higher recovered volume alone therefore cannot demonstrate stronger margins or a broad market recovery.
The supply question needs operating evidence
The partners had already announced a pause in the Tuzo Phase 3 expansion in February. De Beers’ July interim report described operations focused on remaining ore in the current cut. This chronology matters: the pause predates the October restructuring and should not be presented as its consequence.
For cutters, dealers and jewellery businesses, the useful next evidence is confirmation of completion, an updated mine plan and any changes to rough-sales arrangements. The restructuring announcement itself supplies no new production forecast or expansion restart date. Changes in ownership and liabilities should therefore be kept separate from assumptions about additional carats reaching the market.
