Element 25 Limited (E25, Element 25 or Company) (ASX: E25; OTCQX: ELMTF) is pleased to announce its wholly-owned subsidiary, Butcherbird Operations Pty Ltd, has executed a binding long-term offtake agreement with OM Materials (S) Pte Ltd, (OMM) a subsidiary of OM Holdings Limited (ASX: OMH), for 100% of manganese concentrate produced at Element 25’s Butcherbird Mine in Western Australia’s (WA) Pilbara region, with carve-outs to support plans for future feedstock for battery-grade high purity manganese sulphate (HPMSM) production. OM Holdings is a long-established manganese alloy producer and operator of manganese smelting facilities in Malaysia, providing a downstream industrial customer for Butcherbird production. 1 E25 ASX Announcement dated 22 January 2025 2 E25 ASX Announcement dated 27 May 2026 3 AUGUST 2026 | ASX: E25 2 The agreement establishes a long-term sales channel for manganese concentrate from BBX, which is targeting expanded 1.1Mtpa of manganese concentrate production3 and represents a key milestone in advancing BBX towards development and financing. The Offtake contract is the latest agreement executed by Element 25 for BBX, following its recent announcement of long-term Mining Services and Ore Haulage Services Agreements with ReGroup Australia Pty Ltd (ReGroup)4 . Key terms of the agreement include: • OMM will purchase 100% of manganese concentrate production from Butcherbird, capped at ~1.1 Mtpa. • Agreement includes take-or-pay obligations, supporting contracted volumes. • OMM granted exclusive global marketing rights for conforming product, with limited carve outs for non-conforming material and Element 25’s own downstream processing requirements. • Pricing is based on a transparent index-linked framework, referencing internationally recognised manganese ore benchmarks and includes quality-based adjustments reflecting product specifications, with freight normalisation to free on board (FOB) basis. • Periodic pricing reviews to ensure alignment with prevailing market conditions. • Includes staged payment arrangements linked to production, shipment and final reconciliation. • Initial five-year term from first shipment, with option for extension of up to five additional years, subject to performance and review. • Agreement is subject to customary conditions, including Board approval, project financing (including NAIF funding) becoming unconditional and regulatory approvals. Element 25 Managing Director Justin Brown said: “This agreement secures a high-quality, long-term offtake partner for manganese concentrate produced at our expanded Butcherbird Operations, extending our existing relationship with OMH and its subsidiary, OMM. OMH has established downstream smelting capability, providing a strong commercial foundation for the Butcherbird Project over the initial five years of operation, and potentially beyond that timeframe. Securing a strong offtake partner also represents a major step forward in de-risking the development pathway for our Butcherbird expansion, giving lenders and investors the confidence needed to support project financing. The structure of our agreement delivers revenue certainty while still preserving market exposure, ensuring we participate in upside conditions without compromising stability. Importantly, the agreement maintains our strategic flexibility, allowing Element 25 to continue advancing our value-added downstream ambitions, including our HPMSM battery materials program.” 3 E25 ASX Announcement dated 22 January 2025 4 E25 ASX Announcement dated 27 May 2026 3 AUGUST 2026 | ASX: E25 3 Product specification is aligned with standard manganese concentrate benchmarks (~31.5% Mn), and there are restrictions on resale into certain downstream markets to support the Company’s plans to produce HPMSM. Element 25 is in the process of expanding Butcherbird, based on an updated January 2025 Feasibility Study5 (BBX FS) and an updated Ore Reserve of 101.4Mt at 10.4% Mn (10.54Mt contained manganese)6 , supporting an 18+ year Life of Mine (LOM) at the planned throughput rate. As remaining outstanding contracts for BBX close to finalisation, Element 25 currently forecasts mechanical completion and commissioning in Q1 CY2027. ABOUT ELEMENT 25 Element 25 is an ASX-listed company (ASX: E25) that operates the world-class 100%-owned Butcherbird Manganese Project in Western Australia and is currently undertaking activities to recommence production at approximately 1.1Mtpa of medium-grade high silica manganese ore for use in traditional and new energy markets. E25 is also commercialising innovative proprietary technology to produce battery-grade high-purity manganese sulphate monohydrate (HPMSM) for use in Electric Vehicle (EV) battery manufacturing. The Company is planning its first HPMSM refinery in Louisiana USA to produce raw material for the US EV market, with support from General Motors LLC (GM), Stellantis N.V. (Stellantis) and a grant for US$166 million (A$268M) in project funding from the U.S. Department of Energy (DoE) under the Battery Materials Processing Grant Program. An anticipated strategic shift towards lithium manganese rich (LMR) battery chemistries over high nickel formulations will materially increase demand for HPMSM, with GM being one of the first automakers looking to adopt this technology after spending more than a decade on research. Ford Motor Company has also announced a plan to introduce LMR batteries to improve safety, energy density, and reduce costs. LMR battery cells use around to 50-70% manganese increasing the required manganese by up to 10X compared to high nickel ternary chemistries.
