Arianne Phosphate Extends Its Credit Facilities

Press Release

SAGUENAY, QUEBEC – (March 12, 2026) – Arianne Phosphate (the “Company” or “Arianne”) (TSX VENTURE: DAN; OTCQB: DRRSF; FRANKFURT: JE9N), a development-stage phosphate mining company, advancing the Lac à Paul project in Quebec’s Saguenay-Lac-Saint-Jean region, is pleased to announce that it has entered into an agreement as at the date hereof (the “2026 Letter Agreement”) with its senior secured lender Mercury Financing Corp. (“Mercury” or the “Lender”) to extend until September 30, 2027 its three existing credit facilities respectively dated August 21, 2012, July 29, 2013 and October 20, 2015, as subsequently amended.  The extended secured credit facilities are in the aggregate amount of $26,328,001 (the “Loan”) and were set to expire on March 31, 2026. The aggregate amount of the Loan includes an aggregate amount of $1,850,873 in accrued interest payable in common shares of the Company as detailed below. These credit facilities will continue to bear interest at an annual rate of 8%, with all interest capitalized through maturity. The extension is subject to the parties executing definitive agreements in connection with the transactions contemplated under the 2026 Letter Agreement by no later than March 31, 2026 (the “Closing Date”).

“Mercury’s willingness to extend Arianne’s credit facility should be taken as a very positive sign by investors,” said Marco Gagnon, Executive Chairman of Arianne. “In particular, the fact that many of the terms of the facility are tied to the performance of the Company’s equity by way of common shares and warrants, allows for the alignment of interests by all parties involved. It also validates the importance of recent corporate events over the last few months including the extension of Arianne’s permit and production of a very high purity phosphate concentrate, allowing us to target specialty applications like the LFP battery.”

Highlights of the Agreement with Mercury

• The Company has agreed to pay the accrued interest on the Loan from April 1, 2025 up to the 2026 Letter Agreement in common shares at a price of $0.26, for a total of 7,118,742 common shares in full and final payment of such accrued interest. The Company has also agreed to pay the accrued interest on the Loan from the 2026 Letter Agreement to the Closing Date in common shares at a price per share equal to the closing market price of the common shares on the TSX Venture Exchange (“TSX-V”) on the date immediately prior to the Closing Date (collectively, the “Interest Payment Shares”);
• The Company will issue 10 million common shares (the “2026 Shares”) to the Lender on the Closing Date.  The Lender has agreed to the following voluntary hold periods: 5 million 2026 Shares subject to a voluntary hold period of 6 months from the Closing Date and 5 million 2026 Shares subject to a voluntary hold period of 9 months from the Closing Date (collectively, the “Voluntary Hold Period”). In the event the Company completes an equity financing following the Closing Date, the Voluntary Hold Period shall be reduced to the lesser of (a) the period of time remaining under the Voluntary Hold Period and (b) the regulatory hold period, if any, applicable to the securities issued by the Company under such equity financing. Furthermore, the Voluntary Hold Period shall automatically terminate in the event of a merger, amalgamation, acquisition, disposition, arrangement or other business combination transaction involving Arianne (a “Business Combination Transaction”).
• The Company will issue 25 million non-transferable warrants (the “2026 Warrants”) entitling the Lender to acquire the same number of common shares at a price of $0.28 per share until September 30, 2027, subject the requirements under the policies of the TSX-V in the event of a total or partial voluntary repayment of the Loan by Arianne within the first year following the Closing Date. Furthermore, the Lender shall not be entitled to exercise such aggregate number of 2026 Warrants which would result in the Lender holding, following such exercise, on a partially diluted basis, more than 19.9% of the issued and outstanding common shares of the Company. The Lender shall nevertheless be entitled to exercise the 2026 Warrants without the limitations of these warrant exercise restrictions applying in the event of a Business Combination Transaction. In the event of a transaction of the Company resulting in the creation of a new Control Person (as defined in the policies of the TSX-V) and requiring the Company to obtain disinterested shareholder approval in connection with such transaction, the Company shall also request the approval of its disinterested shareholders in order to remove the warrant exercise restrictions from said 2026 Warrants, thereby entitling the Lender to become a Control Person of the Company;
• For as long as the Loan remains outstanding, the Lender shall have the right to designate a nominee for appointment to the board of directors of the Company and such nominee shall be appointed as a member of the Human Resources and Corporate Governance Committee;
• Arianne agrees to pay to the Lender an additional production fee of $0.25 per metric ton of phosphate concentrate sales for the life of the project, including any non-arm’s-length sales or in connection with any non-arm’s-length transformation of such phosphate concentrate, which can be repurchased at any time for a lump sum payment of $2.25 million. Should Arianne fail to reimburse the Loan in full on or before March 31, 2027, the Company agrees to pay to the Lender an additional production fee of $0.25 per metric ton of phosphate concentrate sales, including any non-arm’s-length sales or in connection with any non-arm’s-length transformation of such phosphate concentrate, which additional production fee can be repurchased at any time for a lump sum payment of $2.25 million.

The credit facility extension and other transactions contemplated under the 2026 Letter Agreement remain subject to TSX-V approval. Furthermore, the Interest Payment Shares, the 2026 Shares and the 2026 Warrants will be subject to a regulatory hold period of four months and one day from their date of issuance.
