TSX and OTC: MPVD

TORONTO and NEW YORK, Feb. 10, 2026 /PRNewswire/ -- Mountain Province Diamonds Inc. ("Mountain Province" or the "Company") (TSX: MPVD) (OTC: MPVD) provides a corporate update on its senior management and recent financial and operational matters primarily regarding its joint venture with De Beers Canada Inc. ("De Beers") pursuant to which the Company holds a 49% interest and De Beers holds a 51% interest in the Gahcho Kué Mine in the Northwest Territories (the "Mine").

Appointment of Jonathan Comerford

Following the departure of Mark Wall, the Board of Directors has decided, as part of ongoing cost-saving measures, not to seek a replacement at this time. The Board has appointed Jonathan Comerford, currently Chairman of the Board, as acting President and CEO.

Tuzo Phase 3

De Beers and Mountain Province, have made the decision to pause the Tuzo Phase 3 project at the Mine

This decision follows a careful assessment of the project's economics considering the prevailing market environment. While the Tuzo Phase 3 project has demonstrated strong potential, current market conditions have prompted the partners to take a measured approach to its development.

The partners remain committed to responsibly managing operations at the Mine and will continue to monitor market conditions to determine the optimal timing for any future development of the Tuzo Phase 3 project.

Importantly, this decision will not impact carat production in 2026 or the number of carats the Company expects to sell in 2026, as the current focus remains on mining out the high-grade NEX pipe. The Company will be issuing its Q4 2025 production and sales figures later this week, along with its guidance for 2026.

Joint Venture with De Beers

The Company has received three in-kind election notices (together, the "IKE Notices") from De Beers pursuant to the amended and restated joint venture agreement between the Company and De Beers dated as of March 18, 2025 (the "JVA") for an aggregate amount of CAD$49,171,619 (the "Cash Call Amount" and together with the default interest accruing thereon, the "Outstanding Cash Call Amount").

Receipt of the IKE Notices does not constitute an event of default under the JVA however failure to pay the outstanding amount under any IKE Notice within 60 days of that IKE Notice will constitute a formal event of default under the JVA, unless otherwise agreed between the joint venture partners. A formal event of default under JVA will constitute a cross default under the Company's other secured indebtedness.

Payments under the first IKE Notices for the Outstanding Cash Call Amount are due March 17, 2026 (as to $38,847,140) and, as to the balance of the Outstanding Cash Call Amount, weekly thereafter.

The Company anticipates that the proceeds from scheduled diamond sales may be sufficient to satisfy the first Outstanding Cash Call Amount due March 17, 2026.

In addition, the Company received an IKE Notice in respect of amounts overdrawn by the joint venture from time-to-time to finance prior operations at the Mine (the "Overdraft IKE") The Company has not had an opportunity to review and consider the merits or quantum of the claim for Overdraft IKE, which is outside of the current arrangements with De Beers.

The Company has been in and is in continuing discussion with De Beers regarding the IKE Notices and both the Company and De Beers are working together to identify opportunities to reduce joint venture costs, while maintaining value for stakeholders.

Extension for Approval of Facility Fee

As announced on July 28, 2025, as consideration for a US$10M increase to its bridge term facility under its amended and restated bridge credit facility agreement with Dunebridge Worldwide Ltd., ("Dunebridge"), the Company agreed to pay Dunebridge a US$1 million fee (the "Facility Fee") on maturity.

Either the Facility Fee was to be approved by disinterested shareholders, or such shareholder approval was not to be required by January 25, 2026 (the "Outside Date"), failing which an event of default will have occurred under the amended and restated bridge credit facility agreement. To permit such shareholder approval to be obtained at the Company's 2026 annual general meeting of shareholders, Dunebridge extended the Outside Date to June 30, 2026.

Mountain Province Diamonds President and CEO Jonathan Comerford commented:

"The challenges currently facing the Company largely reflects the prolonged weakness in the diamond sector. In this environment, our focus remains on carefully managing costs, protecting liquidity, and making measured decisions to support the long-term sustainability of our operations. We are working closely with De Beers and our stakeholders to address the in-kind election notices and to secure the ongoing viability of both the Company and the Gahcho Kué mine."
