Announcement PDF BPH GLOBAL LTD ACN 009 104 330 21 February 2025 Company Announcements Pla8orm Australian Securi;es Exchange Excep&onal silver and cobalt assays from seaweed cul&va&on Highlights • Silver Assays up to 12.67 mg/kg • • Cobalt Assays up to 13.68mg/kg Seaweed was grown using clean, filtered seawater from the island of Sentosa • • Testwork to be conducted on seaweed culQvated in polluted, brackish water in Johor, Malaysia Scope of tesQng for next batches to be expanded to include Copper and Gold The Board of BPH Global Ltd (ASX: BP8) (Company), is pleased to announce the ini;al laboratory assay results of the R&D program conducted by Temasek Innova;on Holdings Pte Ltd (TPIH), an opera;ng company of Temasek Polytechnic in Singapore, in conjunc;on with the Company’s Singapore-based R&D consultant Gaia Mariculture Pte Ltd (Gaia Mariculture). Managing Director MaYhew Leonard said: “The presence of cobalt and silver in the seaweed has been an exci;ng development. It appears that the seaweed has the poten;al to act like a sponge for base and precious metals in seawater and we intend to inves;gate this further.” Figure 1: Sesuvium Portucalastrum seaweed cul*vars growing in Gaia Mariculture’s laboratory in Singapore Background The Company previously announced its execu;on of an outsourcing R&D agreement, pursuant to which TPIH is undertaking a R&D program to develop the technology and exper;se to locate, separate and extract minerals from seaweed by deploying phycomining techniques. In doing so, the Company is seeking to confirm that seaweeds grown in polluted waters will contain higher concentra;ons of minerals than those grown in pris;ne waters. This R&D collabora;on with TPIH compliments the Company’s other seaweed-based ac;vi;es and follows the comple;on of the Company’s joint venture transac;on to establish its Indonesia-based seaweed business. The Company’s main undertaking is the sale of raw seaweed into ASEAN seaweed and food markets. Other exis;ng and proposed ac;vi;es include: (i) the proposed produc;on of bio s;mulant seaweed products for sale in the Indian market; (ii) extrac;on of seaweed-based nutraceu;cals for infusion in food, health and cosme;c products; and (iii) the proposed capture of biohydrogen and other bio-gases as a byproduct of the processing of seaweed. Phase 1 Work Plan The seaweed species Sesuvium Portucalastrum was cul;vated in early December 2024 at the Gaia Mariculture’s laboratory in Singapore. The process u;lised clean, filtered seawater from the Singapore Island of Sentosa, without industrial/urban pollu;on and without sediment. Two harvests of the seaweed were taken in January 2025 with Batch 1 on the 6th of January and Batch 2 on the 21st January. Both batches were sent to TPIH for processing and assaying for metal content. The samples from each batch were digested using concentrated nitric acid and hydrogen peroxide. The samples were then filtered and diluted to facilitate metal determina;on using Induc;vely Coupled Plasma– Mass Spectrometry (ICP-MS) with results shown in Table 1. Table 1: Assay results of samples from Batch 1 and 2 u?lising ICP-MS Metal Co Ni As Ag Cd Pb Metal Content (mg/kg) Batch 1 13.68 0.80 0.53 2.76 0.31 0.93 Batch 2 0.25 0.89 0.52 12.67 0.00 0.61 Phase 1 R&D Objectives and Findings The primary objec;ve of the Phase 1 R&D program was to test for the presence of minerals in 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). Ini;al focus was on a small suite of base and precious metals of high intrinsic value including Nickel (Ni), Arsenic (As) and Silver (Ag) and Cobalt (Co). The analysis of the assay results indicates that: • The Sesuvium Portucalastrum seaweed species appears to be a good absorber of minerals. • Early accumula;on of minerals occurs in the leaves of the seaweed and subsequently in the stems and roots. • Silver is accumulated incrementally over ;me with Batch 2 concentra;on approximately 6 ;mes higher than Batch 1. • • Seaweed should be harvested at the end of its lifecycle to maximise the Silver content. Cobalt is absorbed quickly but is subject to leaching over a longer dura;on with Batch 2 concentra;on significantly lower than Batch 1. • Cobalt is accumulated primarily in the leaves, and leaching can occur due to leave drop at more mature phases of the growth cycle. • To maximise Cobalt content, the seaweed should be harvested early on in its growth cycle. • The concentra;ons of Nickel (Ni) and Arsenic (As) remained constant in Batch 1 and Batch 2. Next Steps The primary objec;ve of Phase 2 will be to cul;vate the Sesuvium Portucalastrum seaweed species 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 grown in dirty, polluted waters will absorb higher concentra;ons of minerals than seaweed grown in pris;ne waters due to the “sponge” effect. In addi;on, the mineral search will be expanded to include Gold (Au) and base metals including Copper (Cu).
