Announcement PDF 7 March 2025 Company Announcements Pla8orm Australian Securi;es Exchange Excep&onal gold and copper assays from seaweed cul&va&on Highlights • • Gold Assays up to 14.85 mg/kg Copper Assays up to 10.88mg/kg • Assays from further tes>ng of Phase 1 Seaweed grown using clean, filtered seawater from the island of Sentosa • Testwork to be conducted on seaweed cul>vated in polluted, brackish water in Johor, Malaysia The Board of BPH Global Ltd (ASX: BP8) (Company), is pleased to announce the latest laboratory assay results from its ongoing R&D program conducted by Temasek Innova;on Holdings Pte Ltd (TPIH), an opera;ng company of Temasek Polytechnic in Singapore, in collabora;on with the Company’s Singapore-based R&D consultant Gaia Mariculture Pte Ltd (Gaia Mariculture). Managing Director MaWhew Leonard said: “The presence of gold and copper, in addi;on to the previously iden;fied cobalt and silver, marks another exci;ng milestone in our research. These results further support our view that seaweed has the poten;al to act like a sponge for base and precious metals in seawater. We look forward to inves;ga;ng this further in Phase 2 of the R&D Program.” Phase 1 Work Plan and addi>onal tes>ng As detailed in the Company’s announcement on 21 February 2025, Phase 1 focused on the cul;va;on of Sesuvium Portucalastrum in a controlled laboratory se^ng. The process, ini;ated in early December 2024 at Gaia Mariculture’s Singapore facility, used clean, filtered seawater sourced from Sentosa Island—free from industrial or urban pollu;on and sediment. Ini;al tests revealed excep;onal silver and cobalt levels. Following these results, the Company asked TPIH to undertake addi;onal assays on Batch 1 of Phase 1 to measure the gold and copper content. The samples, previously processed with concentrated nitric acid and hydrogen peroxide, were filtered and diluted for analysis using Induc;vely Coupled Plasma–Mass Spectrometry (ICP-MS). The results are presented in Table 1 below: Table 1: Assay results of samples from Batch 1 u6lising ICP-MS Metal Gold Copper Batch 1 metal content (mg/kg) 14.85 10.88 Phase 1 R&D Objectives and Findings The primary objec;ve of Phase 1 was to assess the mineral absorp;on capabili;es of Sesuvium Portucalastrum seaweed grown in the laboratory in pris;ne waters (clean, filtered seawater from the Singapore Island of Sentosa, without industrial/urban pollu;on and without sediment). The ini;al focus on a small suite of base and precious metals of high intrinsic value including Nickel (Ni), Arsenic (As), Silver (Ag) and Cobalt (Co). This was expanded to test for Gold (Au) and Copper (Cu) based on the ini;al results. The analysis of the addi;onal assay results on Batch 1 further indicates that Sesuvium Portucalastrum seaweed species appears to be a good absorber of minerals, including gold and copper. Next Steps Building on the announcement from 21 February 2025, Phase 2 will shie focus to cul;va;ng Sesuvium Portucalastrum seaweed species in brackish waters of Johor, Malaysia that are proximate to shipping lanes and industrial ac;vity. This will enable the Company to test its hypothesis that seaweed absorbs higher mineral concentra;ons in dirty, polluted waters than seaweed grown in pris;ne waters due to the “sponge” effect. Further updates The Company will provide further updates regarding the Phase 2 cul;va;on and assays cycle. This announcement has been approved for release by the Board of Directors. - END For further informa=on, please visit our website at www.bp8global.com or contact: Mr Paul Stephenson BPH Global Limited Chairman E: pauls@bp8global.com
