Announcement PDF 1 1 ASX Announcement 9 June 2026 Chariot Expands Resurgent Lithium Footprint in McDermitt Caldera HIGHLIGHTS • Chariot’s U.S. subsidiary, FMS Lithium Corporation, has expanded its interest in the Resurgent project, staking 573 additional claims at Resurgent East in the eastern McDermitt Caldera. • The move to acquire these claims follows a disciplined reduction of claims at Resurgent during the recent lithium downturn when FMS Lithium Corporation relinquished some claims in order to preserve capital while retaining exposure to the core Resurgent opportunity. • Assuming the new claims are processed by the county and the BLM, the new claims will nearly double FMS Lithium Corporation’s interest in Resurgent from the current 597 claims to 1,170 claims, representing approximately 81% of its earlier and peak 1,450-claim position at Resurgent. • The additional claims strengthen Chariot's position in the eastern McDermitt Caldera, adjacent to Lithium Americas' Thacker Pass development and Jindalee's McDermitt project. Chariot Resources Ltd (ASX: CC9) (“Chariot” or the “Company”) advises that its 79.4%-owned U.S. subsidiary, FMS Lithium Corporation (“FMS”), has staked 573 additional mining claims at Resurgent East, significantly expanding Chariot’s strategic footprint in the McDermitt Caldera which straddles the Nevada–Oregon border in the United States. Chariot has moved to rebuild its Resurgent position due to the recovery in lithium prices. During the 2023–2025 lithium market downturn, the Company relinquished ground at Resurgent in order to preserve capital while retaining exposure to the core Resurgent opportunity. The newly staked claims mark a decisive step to regain a substantial portion of that strategic footprint as lithium market 2 conditions improve and inbound third-party interest in the McDermitt Caldera increases. The new claims remain subject to completion of the required county and BLM filing and recording process. A Location that Appears Poised for Rapid Development Resurgent is strategically positioned within a prominent U.S. lithium district that is transitioning from the exploration phase to active production. Lithium Americas’ neighboring Thacker Pass project is currently under construction and represents a significant milestone and barometer of potential within the district. The development of Thacker Pass is supported by a loan of US$2.23 billion from the U.S. Department of Energy and strategic investments from major industry players such as General Motors (GM) and Orion. The U.S. Government also maintains warrant-based equity positions in both Lithium Americas and the Lithium Americas/GM joint venture, further demonstrating the importance and growth potential of this emerging lithium-hosting region. GM holds a 38% interest in the Thacker Pass joint venture. 1 On the northern flank of the caldera, Jindalee Lithium’s McDermitt project is a second major resource that demonstrates and confirms the scale of the basin in which Resurgent sits. 2 By securing the additional ground now, Chariot materially expands its lithium resource potential, strengthens its control of prospective tenure on the eastern side of the caldera, and enhances its position in anticipation of the next phase of partnering and funding discussions. Claim status and pro forma Tenure Category Claims Status Earlier Resurgent position 1,450 Historical reference point Existing Resurgent claims 597 Current publicly reported baseline Newly staked Resurgent East claims 573 Staked; subject to completion and acceptance of county and BLM filing / recording Pro forma Resurgent package ~1,170 Subject to completion and acceptance of required filings Approximate increase ~96% Calculated against existing 597 claims Approximate rebuild vs earlier 1,450-claim position ~81% Pro forma 1,170 claims as a percentage of earlier 1,450-claim position The historical and pro forma claim figures remain subject to final claim reconciliation and completion and acceptance of the required county and BLM filings by the county and BLM. The newly staked claims should be treated as staked and subject to recordation until the relevant filings are completed and accepted. 1 https://lithiumamericas.com/thacker-pass/overview/default.aspx 2 https://www.jindaleelithium.com/operations/ 3 Project Overview Resurgent is a claystone-hosted lithium project located in the eastern half of the McDermitt Caldera, immediately north-east of Thacker Pass and abutting the McDermitt deposit to the north. FMS has a direct ownership interest in the claims. Chariot has a 79.4% ownership interest in FMS. FMS is managing the permitting process and will manage the upcoming exploration program at Resurgent. As previously announced (ASX Announcement dated 2 October 2025), Chariot has defined 32 high- priority lithium drilling targets at Resurgent using surface sampling results returning up to 3,865 ppm Li. Chariot has designed a minimal-disturbance maiden drilling program that remains subject to permitting. No new exploration results are reported in this announcement.

Complete the county and BLM filing / recording process for the newly-staked claims. 2. Reconcile the newly staked claims against previously relinquished ground to confirm the extent of strategic ground recovered. 3. Update internal GIS and tenure datasets to reflect the expanded position. 4. Integrate the new claims into Chariot’s Resurgent exploration model. 5. Continue pursuing the permits for the planned maiden drilling program. 6. Continue evaluating strategic options in relation to Resurgent with a view to maximising shareholder value.

In addition to the recently announced acquisition of a Nigerian lithium portfolio which has yet to close, Chariot has twelve (12) lithium projects, including two core projects in the United States (the “Core Projects”) and a number of exploration pipeline projects which Chariot majority owns and operates. The Core Projects include Chariot’s Black Mountain Project (which is prospective for hard rock lithium) in Wyoming, USA and the Resurgent Project (which is prospective for claystone lithium) in Nevada and Oregon, USA. Initial survey results from the Core Projects indicate high-grade lithium mineralisation at surface. The Nigerian portfolio of hard-rock lithium assets consists of four project clusters (Fonlo, Gbugbu, Iganna, and Saki) in the Oyo and Kwara states which cover approximately 254 square kilometers and are comprised of 8 exploration licences and 2 small-scale mining leases. These assets represent one of the largest portfolios of lithium assets in the country and have a history of significant artisanal lithium mining. Chariot anticipates completing the acquisition of the Nigerian portfolio in the second half of this calendar year. Chariot also holds an interest in two hard rock lithium exploration pipeline projects located in Wyoming, USA, the Copper Mountain Project and the Tin Cup Project. In addition, Chariot holds a portfolio interest in certain properties prospective for claystone hosted lithium located in the State of Nevada in the United States through its interest in Mustang Lithium LLC.
