1 1 30 July 2026 ANTILLES GOLD QUARTERLY REPORT & APPENDIX 5B – 30 JUNE 2026 U.S. SANCTION OF CUBAN JOINT VENTURE MINING COMPANY On 4 June 2026, the Cuban joint venture mining company, Minera La Victoria SA (“MLV”), was designated by the U.S. Department of Treasury’s Office of Foreign Assets Control (“OFAC”) as a Specially Designated National (“SDN”). The U.S. Department of State (“DoS”) press release announcing the designation explains the rationale of Executive Order 14404 under which it is made, and that any U.S. entity or person is generally prohibited from transacting with an SDN and secondary sanctions may be imposed on parties from other jurisdictions. The press release is available at: https://www.state.gov/releases/office-of-the-spokesperson/2026/06/sanctions on-cuban- actors-responsible-for-subversive-anti-american-activities-fact-sheet/ As a consequence, Antilles Gold Limited’s subsidiary, Antilles Gold Inc (“AGI”), which is a 50% shareholder in MLV, advised its Cuban joint venture partner, Gold Caribbean Mining S.A. (“GCM”), that it was suspending its direct participation in the administration and management of MLV’s activities while it evaluates the implications of the OFAC designation, and available options. Following discussions with DoS, AGI submitted a Proposal to DoS suggesting changes to the operation and structure of the joint venture that could lead to the lifting of the sanction, or OFAC licencing MLV to transact with U.S. entities or persons. To advance the Proposal, a potential cornerstone U.S. investor in AGI is required to approach DoS directly on the matter and gain approval for the various stakeholders to undertake negotiations on the proposed commercial arrangements and commitments to DoS. AGI is in preliminary discussions on this matter with potential U.S. investors. The following activities during the Quarter took place prior to their suspension on 4 June 2026.
