• EAU Lithium executes Negotiation Agreement with Bolivia's state-owned lithium company YLB
• Cosmos notifies intention to exercise option to acquire 100% of EAU Lithium
• Successful A$5.0 million placement to advance exploration and support EAU Lithium acquisition

Cosmos Exploration (ASX: C1X) has continued to advance its interest in EAU Lithium Pty Ltd during the quarter, with key developments including the execution of a Negotiation Agreement between EAU Lithium and Yacimientos de Litio Bolivianos (YLB), Bolivia's state-owned lithium company, and the notification of Cosmos' intention to exercise the option to acquire 100% of EAU Lithium's issued share capital, subject to shareholder approval. The company also received firm commitments for A$5.0 million (before costs) through a placement to institutional and sophisticated investors, which will be used to support the proposed EAU Lithium acquisition and advance the company's exploration program across its Australian and Canadian project portfolio. While field-based exploration activities were not undertaken during the quarter due to seasonal constraints, technical and desktop evaluation work continued across the company's assets. Cosmos is well-positioned to execute on its strategic priorities, with the placement proceeds complementing its existing cash reserves of approximately A$3.8 million as of 31 March 2026.

Cosmos Exploration will focus on completing the acquisition of EAU Lithium, subject to shareholder approval, and advancing exploration program planning across its Australian and Canadian project portfolio, supported by the A$5.0 million placement proceeds.
