CHATHAM ROCK ANNOUNCES LOAN AGREEMENT

Chatham Rock Phosphate Ltd. entered into a secured loan agreement on Aug. 9, 2025, with Wetstone Global Inc., an arm's-length party, and its wholly owned subsidiary Chatham Rock Phosphate (NZ) Ltd. (CRPNZ), pursuant to which Wetstone agreed to lend CRPNZ the sum of $150,000 (U.S.). The company did not announce the loan agreement on the date of signing in error.

The loan is to be used by CRPNZ for working capital, and is secured against the assets of CRPNZ, specifically its Chatham Rise project. The loan agreement also contains provisions allowing for the conversion of the loan into shares of CRPNZ only upon CRPNZ entering into a definitive agreement in relation to a transaction involving the provision of equity finance (including financial instruments convertible into equity), at a conversion rate fixed under the loan agreement. No finder's fee was payable in connection with the loan.

We seek Safe Harbor.
