Australia: Perth,Western Australia USA: Houston, Texas Metallium Ltd ASX: MTM | OTCQX: MTMCF ENGAGE WITH THIS ANNOUNCEMENT ON INVESTORHUB: HERE ASX Announcement 05 January 2026 METALLIUM EXECUTES BINDING E-SCRAP SUPPLY AGREEMENT WITH GLENCORE Metallium Limited (“Metallium” or the “Company”) (ASX: MTM; OTCQX: MTMCF) is pleased to announce that its U.S. subsidiary, Flash Metals USA Inc. has executed a binding electronic-scrap (“e-scrap”) supply agreement with Glencore Ltd. (“Glencore”), a major recycler of end-of-life electronics, lithium-ion batteries, and other critical metal-containing products1 . The agreement marks a significant commercial milestone for Metallium, providing secure long-term access to e-scrap feedstock to support the ongoing commissioning and scale-up of the Company’s Flash Joule Heating (FJH) technology platform in the United States. This agreement is Metallium’s first binding feedstock supply contract and marks the Company’s transition from development into commercial commissioning and execution. Securing a multi-year supply from a global Tier-1 recycler provides the throughput certainty required to scale Metallium’s U.S. FJH operations, enabling predictable processing rates and multi-line deployment across the Company’s Technology Campus. HIGHLIGHTS: ▪ Metallium has executed a binding contract for the supply of up to 2,400 tonnes per annum of e-scrap from Glencore into the Company’s U.S. operations. ▪ The agreement establishes a secure, multi-year feedstock foundation supporting ongoing commercial commissioning and subsequent scale-up of FJH processing lines. ▪ The contract reflects Glencore commercial terms for secondary materials and follows technical and commercial collaboration under the parties’ previously announced MOU2 . ▪ Metallium and Glencore continue to progress a separate binding offtake agreement, consistent with the framework outlined in the MOU. ▪ Metallium has secured its first binding, long-term feedstock supply contract, underpinning the Company’s transition into U.S. commercial operations, with several more similar agreements under negotiation. ▪ The agreement delivers feedstock certainty during commissioning, enabling predictable reactor utilisation and future multi-line scale-up. STRATEGIC IMPORTANCE Securing contracted feedstock is fundamental to operating stable mass-balance planning during commissioning, predictable reactor utilisation and scalable deployment of FJH processing lines across Metallium’s U.S. Technology Campus. As the Company’s inaugural binding supply agreement, it establishes Metallium’s commercial operating base in the United States and materially accelerates the timetable for FJH capacity expansion. The agreement also enhances Metallium’s position within the rapidly developing U.S. critical-materials recycling landscape, supporting deeper engagement with downstream refiners, OEMs and strategic partners. Metallium Managing Director & CEO Mr Walshe said: “This is a defining moment for Metallium. Our first binding supply agreement gives us exactly what every processing technology company needs most: consistent, secure, high-quality feedstock. Glencore’s commitment allows us to commission and scale with confidence, and it’s a strong validation of our FJH technology and U.S. strategy. We look forward to building on this relationship as we finalise the complementary binding offtake agreement.” 1 Glencore 2025, https://www.glencore.com/what-we-do/recycling? 2 Ref ASX: MTM release 02/10/2025, ‘E-Waste Supply & Metal Offtake MOU Executed with Glencore’. 2 ASX: MTM | OTCQX: MTMCF NEXT STEPS • Commencement of delivery scheduling and logistics to support commissioning and initial commercial-scale processing campaigns. • Finalisation of the separate binding offtake agreement covering metal products recovered via FJH. • Further updates will be provided as additional milestones are achieved. Apart from the binding nature of the agreement and the contracted annual supply volume, all other commercial terms remain commercial-in-confidence as agreed by both parties. The Company confirms that the undisclosed terms are customary for Glencore’s secondary-materials supply arrangements and do not alter the strategic significance of the agreement. E-WASTE AND PCB RECYCLING CONTEXT Printed circuit boards (“PCBs”) represent one of the highest-value waste streams in the global recycling industry, containing elevated concentrations of gold, silver, palladium and copper relative to most primary ores. The accelerating replacement cycle for servers, telecom infrastructure, defence electronics and EV power systems has resulted in a sustained increase in U.S. PCB scrap generation, positioning technology-metal recycling as one of the most strategically important segments of the broader circular-economy landscape3 . Despite this, the U.S. has historically relied on exporting PCB scrap to offshore smelters due to limited domestic processing capacity. Conventional pyrometallurgical routes are capital intensive, slow to build and optimised for copper concentrates rather than heterogeneous, polymer-rich PCB streams. As a result, a significant proportion of U.S. e-waste has been processed overseas, creating long logistics chains, variable recoveries and limited transparency for downstream customers seeking secure, domestic supply of critical metals. Metallium’s Flash Joule Heating (FJH) platform provides a modular, electrically driven and rapidly deployable alternative to conventional smelting. By instantaneously liberating metals from complex waste matrices, FJH enables the production of consistent metal-bearing intermediates from PCBs and related technology waste streams, offering a pathway to domestic onshoring of high-value metal recovery aligned with U.S. industrial-policy and supply-chain resilience objectives. The binding supply agreement with Glencore delivers the feedstock certainty required to support Metallium’s commercial scale-up in the United States. Glencore is one of the world’s largest recyclers of end-of-life electronics, and a major recycler of complex secondary copper, nickel, cobalt, gold, silver, platinum and palladium bearing feeds, and this agreement provides a reliable, well-characterised and scalable source of PCB-rich scrap for the Company’s Technology Campus in Texas. With commissioning now underway at its Texas Technology Campus, Metallium is positioning FJH as a near-term domestic processing solution for PCB-rich waste streams.
