CHATHAM ROCK ANNOUNCES LOAN AGREEMENT

WELLINGTON New Zealand - Chatham Rock Phosphate Limited, "CRP" or "the Company" (TSXV: "NZP", NZX: "CRP" FSE "3GRE") announces it entered into a secured loan agreement (the "Loan Agreement") on August 9, 2025 with Wetstone Global Inc. (the "Lender"), an arm's length party, and its wholly-owned subsidiary Chatham Rock Phosphate (NZ) Limited ("CRPNZ"), pursuant to which the Lender agreed to lend CRPNZ the sum of USD$150,000 (the "Loan").
