Mountain Province Diamonds Announces US$10 Million Additional Borrowings Under Bridge Facility

TSX and OTC: MPVD

TORONTO and NEW YORK, July 28, 2025 /PRNewswire/ -- Mountain Province Diamonds Inc. ("Mountain Province" or the "Company") (TSX: MPVD) (OTC: MPVD) announces today that it has entered into an amendment (the "Amendment")  to the amended and restated bridge credit facility agreement with Dunebridge Worldwide Ltd., ("Dunebridge") to increase such the size of the bridge term facility under that agreement by US$10 million (the "Additional Bridge Term Facility"), from US$30 million to US$40 million.

The bridge credit facility agreement, which was originally entered into on February 24, 2025 (and was subsequently amended and restated on May 13, 2024, to provide for a US$33 million working capital facility), provided for US$30 million in immediately available funds to the Company (the "Original Bridge Term Facility"), with the Additional Bridge Term Facility to be made available to the Company at the discretion of Dunebridge on terms and conditions to be agreed to, which are now represented in the Amendment.

The Additional Bridge Term Facility will mature on the same date as the Original Bridge Term Facility, on March 18, 2026, and is subject to the same rate of interest of 10.5% per annum, to be capitalized and compounded quarterly on the principal amount and payable on maturity. The interest rate will increase to 12.5% per annum, if the Additional Bridge Term Facility or the Original Bridge Term Facility are not repaid, together with all accrued interest, upon maturity.

As consideration for the Additional Bridge Term Facility, the Company will pay Dunebridge a US$1 million fee (the "Facility Fee") on maturity. Payment of the Facility Fee is subject to receipt of disinterested shareholder approval in accordance with the TSX Company Manual (the "Manual") at a duly called meeting of the Company's shareholders or such approval no longer being required if the Company obtains an alternative listing of its common shares on the TSX Venture Exchange (the "TSXV") and voluntarily delists its common shares from the Toronto Stock Exchange. The Company has not yet determined whether it will proceed with pursuing a listing on the TSXV. Failure to either obtain the requisite disinterested shareholder approval under the Manual or obtain an alternative listing of its common shares on the TSXV in advance of January 25, 2026, unless waived or extended by the lender will constitute an event of default under the amended and restated bridge facility agreement.

MI 61-101 Reliance on Exemption for Financial Difficulty in Respect of Additional Bridge Facility

Dunebridge is a "related party" of the Company, for the purposes of MI 61-101 and the entering into of the Amendment is a related party transaction for the purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Amendment is being completed pursuant to an exemption from the minority shareholder approval requirements applicable to a related party transaction under section 5.7(1)(e) of MI 61-101 on the grounds that the Company is in serious financial difficulty. The board of directors of the Company, acting in good faith, and all of the Company's independent directors, acting in good faith, have determined that entering into the Amendment, generally, and the Additional Bridge Term Facility, including the Facility Fee, is reasonable given the financial difficulties that the Company is facing (the "MI 61-101 Exemption").

TSX Conditional Approval

On the basis that the Amendment involves Dunebridge, an insider and related party of the Company, but does not involve the issuance or potential issuance of the listed securities of the Company, MPD applied for, and received, the TSX's conditional approval for the Amendment and under Section 501(c) of the TSX Company Manual.

The TSX provided conditional approval of the Amendment on the basis that the value of the consideration to insiders in respect of the Additional Bridge Facility (excluding the Facility Fee) will not exceed 10% of the Company's market capitalization as of July 28, 2025, being approximately CAD11.68 million.

Value of Consideration to Insiders

The value of the consideration to insiders for the Additional Bridge Facility (excluding the Facility Fee) is an estimated CAD959,000 as of July 28, 2025 or 8% of the market capitalization of the Company discussed above. Such consideration reflects the interest consideration payable on the Additional Bridge Facility on maturity.

The value of the consideration to insiders for the Additional Bridge Facility (including the Facility Fee) is an estimated CAD2,329,000 as of July 28, 2025 or 20% of the market capitalization of the Company discussed above. Such consideration reflects the interest consideration payable on the Additional Bridge Facility on maturity plus the amount of the Facility Fee.
