USCM Amends McDermitt East Option Agreement to Provide for Acquisition of 100% Interest in the Project

Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - US Critical Metals Corp. (CSE: USCM) (OTCQB: USCMF) (FSE: 0IU) ("USCM" or the "Company"), together with its wholly owned subsidiary US Energy Metals Inc. ("USEM"), is pleased to announce that it has entered into an amending agreement (the "Amendment") with Live Energy Minerals Corp. ("LIVE") and Lithium Valley Holdings Corp. ("LVH") to restructure the terms of the previously-announced Exploration and Option to Enter Joint Venture Agreement dated September 15, 2023 (the "Original Agreement") (see full press release, here). The Amendment provides USCM with a clear path to acquire a 100% ownership interest in the McDermitt East Lithium Project (the "Project" or "McDermitt East"), located in the McDermitt Caldera, one of the largest lithium districts in North America.¹

The McDermitt Caldera is anchored by the Thacker Pass Project, currently being constructed by Lithium Americas. The U.S. government recently acquired an equity stake in Lithium Americas and released the first tranche of a project construction loan. This support is consistent with broader government funding initiatives across the critical minerals sector, including the investment in MP Materials' Mountain Pass rare earth mine.²

By moving forward with consolidating 100% ownership of McDermitt East, USCM expects to strengthen its position as a North American-focused critical minerals company, advancing assets aligned with U.S. government priorities to reduce reliance on Chinese-controlled supply chains.

USCM previously reported sampling results of up to 2,129 ppm lithium at McDermitt East, underscoring the Project's potential as part of a strategically vital U.S. lithium district (reference full press release, here).

Management Commentary

Darren Collins, CEO of USCM, commented: "This transaction represents a significant milestone for USCM, as it provides a direct path to full ownership of McDermitt East, a highly strategic asset located in one of the most important lithium districts in the world. Consolidating our position reinforces our commitment to building a portfolio of projects that directly support U.S. supply chains and critical mineral independence. USCM now controls strategic footholds in the two preeminent lithium districts in the U.S., including the McDermitt and Clayton Vally through its 100% interest in the Clayton Ridge Lithium Project."
