CANADA ADDS PHOSPHORUS TO ITS CRITICAL MINERALS LIST

NEWS RELEASE 24-17 June 11, 2024 CANADA ADDS PHOSPHORUS TO ITS CRITICAL MINERAL LIST WELLINGTON, New Zealand - Chatham Rock Phosphate Limited (“CRP”) (TSXV: NZP, NZX: CRP, Frankfurt Borse: 3GRE) wishes to advise that just as phosphorus was added to the strategic minerals list in Australia, Canada has now added phosphorus to its critical minerals list. See the announcement link below. The European Union and South Korea have also recognized phosphorus as a critical and/or strategic mineral. A decision by the United States Government on the status of phosphorus as a critical and strategic mineral is expected in 2024-25. A US Senate bill (S. 3956) to include phosphorus on the final list of critical minerals of the U.S. Department of the Interior was introduced on March 14, 2024. Canada has limited phosphate resources with small sedimentary phosphate deposits in British Columbia while having extensive but low-grade igneous deposits in Ontario and Quebec. Australian ASX listed Fertoz Limited is developing small phosphate deposits in British Colombia while Canadian company First Phosphate has started development of a large-scale igneous phosphate deposit in Ontario. In the USA, with phosphate production in decline, the current focus is on food and fertilizer production. However, the expected demand for high quality phosphoric acid for lithium iron phosphate ("LFP") battery production will drive the demand for supply of high-quality phosphate rock. CRP is strategically positioned to meet this demand. CRP’s low cadmium rock phosphate projects, Korella, Chatham Rise and Makatea, have the logistical and resulting cost advantage of being able to ship from Pacific Ocean ports providing competitive deliveries of rock phosphate to the west coast of USA including the Port of Longview, (Washington State) and to south west Canada (Port of Vancouver, BC) CRP has already identified potential customers and logistics solutions for importation of CRP phosphates into Canada and USA. Our Korella project, exporting out of the Port of Townsville, provides CRP with the first opportunity to offer rock phosphate to meet the increasing demand for phosphate in North America. https://www.canada.ca/en/natural-resources-canada/news/2024/06/government-of-canada-releases-updated-critical-minerals-list.html For further information please contact: Chris Castle President and Chief Executive Officer Chatham Rock Phosphate Limited 64 21 55 81 85 or chris@crpl.co.nz Statements about the Company’s future expectations and all other statements in this press release other than historical facts are “forward looking statements”.
