CRP Provides Update on Proposed Sale of Korella Projects

NEWS RELEASE 25-08 April 17, 2025 Chatham Provides an Update on the Proposed Sale of its Korella Projects WELLINGTON New Zealand – on 20 January 2025 Chatham Rock Phosphate Limited (TSXV: “NZP”, NZX: “CRP” and “3GRE” (Frankfurt) or the “Company”) advised that we had that day agreed to sell to an arm’s-length Australian entity (the Marshall Group) the four mining and exploration leases in respect of our Korella North and South properties currently held by our 100% owned subsidiary Avenir Makatea Pty Limited (AML). The leases to be sold are ML100379, EPM 28589, EPM 28882 in respect of Korella North and EPM 28178 in respect of Korella South. The sale price included a cash payment of AU$4.1 million (CA$3.65 million, NZ$ 4.5 million) on transfer of the leases to the acquiring company and a royalty to be paid to AML at a rate of AU$10 per tonne for the first 0.19 million tonnes of production (total AU$6 million, CA$5.34 million, NZ 6.6 million). A further royalty of AU$1 would be paid per tonne to AML on all production commencing after the completion of the first 0.19 million tonnes up until 31st March 2040. We also advised then that the transactions were conditional on a successful outcome in respect of a due diligence process to be undertaken by the proposed purchaser which then was currently underway, and which was expected be completed on or before 31st March 2025, as well as the successful negotiation of a definitive purchase and sale contract, and TSXV approval, if applicable. On 24 February we advised that the exclusive due diligence process had been agreed to be extended to 30 June 2025. Subsequently the Marshall Group has moved to a non-exclusive negotiation process as they sought to investigate complementary opportunities in the overall phosphate value chain. Accordingly other parties who earlier expressed interest in the acquisition of the Korella leases have re-engaged. Of recent times CRP has also received unsolicited interest in its other phosphate projects in New Zealand and French Polynesia. There continues to be interest in other phosphate projects. For example, on 16 April 2025 it was announced that Christmas Island based PRL Group are in a final 45-day due diligence period for the acquisition of Centrex Limited and their Australia based Ardmore phosphate mine. Shareholders will be kept informed as matters progress.
