CHATHAM RETURNS TO PDAC 2025

NEWS RELEASE 25-04 February 19, 2025 CHATHAM RETURNS TO PDAC 2025 – THE PREMIER WORLD STAGE FOR RESOURCE INVESTOR OPPORTUNITIES WELLINGTON, New Zealand – Chatham Rock Phosphate Limited (TSXV: NZP and NZX: CRP) (“Chatham” or the “Company") wishes to confirm that it will again have a strategically located booth (#2933) in the Investors Exchange in the Prospectors & Developers Association of Canada (“PDAC”) annual conference being staged in Toronto from March 2nd to March 5th. PDAC is demonstrably the largest mining investment show in the world and has proven to be a most successful venue for the Company in the past. Showcasing Chatham at PDAC has led to subsequent, robust investor support not only from Canada and the USA, but Germany, Switzerland, and the United Kingdom. The Company will be represented by President & CEO Chris Castle and non-executive director Dr Georg Hochwimmer, who, en-route to Toronto, will be presenting to existing and potential new investors in Germany and Switzerland. The timing of this travel ties in particularly well with our current fundraising of 5 million units at CAD 7 cents, NZD 8.6 cents and AUD 7.8 cents (see our press release dated January 21, 2025 on SEDAR+). The Chatham Renaissance Attendance at PDAC 2025 is only a small part of Chatham’s present drive to inform world markets about our Company’s renaissance in the last four and a half years. During that period Chatham has transformed from a single project company facing an uncertain and expensive permitting hurdle to a rapidly expanding group of projects much closer to generating operating cash flows. Phosphate The existing phosphate projects are: 1. Chatham Rise marine project in New Zealand, planned production rate 1.5 Mtpa from 2028; 2. Avenir Makatea – onshore phosphate mine/rehabilitation project, planned production rate 250,000 tpa; 3. Korella South – 2 Mtpa export focussed mine; 4. Korella North – 250,000 tpa production rate aimed at the domestic phosphate market; All of these phosphate deposits are ultra-low in cadmium, a food safety attribute already essential in Europe and likely to become a universal requirement. Ultra-low cadmium rock phosphate is relatively rare and will over time become an increasingly valuable and strategic resource. Rare Earths Rare earths are present on the Chatham Rise as well as in the two Korella project areas. Private Placement of 5 million Units. Shareholders and prospective investors who consider themselves eligible to invest should contact Chris Castle by return email.
