Announcement PDF BPH GLOBAL LTD ACN 009 104 330 11 August 2025 Company Announcements Pla6orm Australian Securi:es Exchange TPIH To Conduct Addi/onal Assays On Seaweed Species Sesuvium Portulacastrum For Further Confirma/on of Metal Uptake Poten/al Highlights • TPIH to conduct addi?onal assays on naturally growing Sesuvium portulacastrum from polluted waters in Johor, Malaysia. • • No cost to the Company for this supplementary work. Focus on gold, silver and rare earth elements content in the harvested biomass. • Builds on recent R&D findings confirming Sesuvium portulacastrum as a hyperaccumulator of high-value metals, with prior assays recording concentra?ons of 5.23–81.32 mg/kg dry biomass. • Results will provide addi?onal suppor?ng evidence for the species’ poten?al scalable deployment as a source of bio-ore. The Board of BPH Global Ltd (ASX: BP8) (BP8 or Company) is pleased to advise that Temasek Innova:on Holdings Pte Ltd (TPIH), in collabora:on with the Company’s Singapore-based R&D consultant Gaia Mariculture Pte Ltd (Gaia Mariculture), has agreed to undertake addi:onal assays on naturally growing Sesuvium portulacastrum seaweed samples harvested from polluted waters in Johor, Malaysia. Gaia Mariculture has already delivered the harvested seaweed samples to TPIH to facilitate the commencement of this work. Importantly, TPIH has confirmed it will conduct this further work at no cost to the Company. These supplementary assays will focus on the mineral content of gold, silver and rare earth elements in the harvested biomass. The work represents a direct extension of the Company’s recently completed six-month R&D program, which confirmed that the halophy:c seaweed species Sesuvium portulacastrum is a hyperaccumulator of minerals, including several high-value metals, when grown in polluted or mineral-rich waters. The purpose of these addi:onal assays is to: • • • Further evaluate mineral uptake in naturally occurring popula:ons of Sesuvium portulacastrum in real-world polluted marine environments; Provide addi:onal suppor:ng evidence on whether naturally growing biomass demonstrates similar or enhanced concentra:ons of precious and rare earth metals compared to previously tested cul:vated samples; and Strengthen the dataset suppor:ng the species’ poten:al for scalable deployment as a source of bio-ore. Managing Director MaYhew Leonard said: “This no-cost extension of our research by TPIH is an excellent outcome for the Company and our shareholders. These further assays will allow us to build on the strong results from our ini:al program, giving us addi:onal suppor:ng evidence on the capacity of naturally occurring Sesuvium portulacastrum in Johor’s polluted waters to accumulate not only precious metals, but also rare earth elements. This incremental data will further underpin our next phase of R&D focused on extrac:on technologies.” The Company will update the market on the results of these addi:onal assays. 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
