Avenir Minerals Limited, a wholly owned subsidiary of Agnico Eagle Mines Limited established in October 2025 to evaluate and advance critical and strategic mineral projects, entered into a definitive Arrangement Agreement on May 4, 2026 to acquire all of the issued and outstanding common shares of Fox River Resources Corporation, other than the Fox River shares already held by Avenir Minerals and its affiliates, by way of a statutory plan of arrangement under the Canada Business Corporations Act. Under the terms of the Arrangement Agreement, Fox River shareholders will receive C$1.10 per share in cash, representing a premium of approximately 20 percent to the 30-day volume-weighted average price of the Fox River shares as of May 1, 2026, for an aggregate purchase price of approximately C$94.3 million on a fully-diluted basis. Fox River's sole material asset is its 100 percent interest in the Martison Phosphate Project, a large-scale igneous phosphate deposit located near Hearst, Ontario, planned as a vertically integrated operation capable of supplying phosphate fertilizers and purified phosphoric acid for the lithium iron phosphate battery industry. The transaction is the Company's first platform-level entry into a critical minerals asset. The Fox River board, on the unanimous recommendation of a Special Committee whose sole member is independent director David Lotan, and on receipt of a fairness opinion from Mills Dunlop Capital Partners Ltd., resolved to recommend that shareholders vote in favour of the arrangement. Directors and officers holding approximately 23.5 percent of the outstanding Fox River shares, together with Adrian Day Asset Management (up to approximately 14.7 percent), entered into voting support agreements. The transaction requires approval of at least two-thirds of the votes cast by Fox River securityholders at a Special Meeting scheduled for June 23, 2026, together with Ontario Superior Court of Justice and customary regulatory approvals.
