Metallium Substantially De-Risks Flash Joule Heating Ahead of 2027 Commercial Launch

Flash Joule Heating Technology Nears Commercial Readiness

Metallium Limited (ASX:MTM) has taken a decisive step from technology development to commercialisation of its Flash Joule Heating (FJH) platform, reporting over 100 test campaigns and a successful prolonged multi-reactor operating campaign. The company now regards the core FJH technology as substantially de-risked, shifting its focus to optimisation, scale-up, and commercial execution.

This milestone was underscored by a 12-hour continuous campaign involving three reactors running simultaneously with 83% availability and near full utilisation, confirming the modular reactor design's scalability and operational integrity. This progress supports the company’s target to begin commercial printed circuit board (PCB) processing and initial product sales in the first half of 2027, contingent on permitting and commissioning milestones.

Texas Technology Campus Advances Amid Permitting and Construction

Construction at Metallium’s Texas Technology Campus, dubbed "Gator Point," continues apace with major infrastructure and laboratory developments to support the next phase of technology scale-up. While roof remediation has temporarily relocated chlorination activities, supplementary permitting applications have been submitted to the Texas Commission on Environmental Quality (TCEQ), with a determination expected in the September quarter.

Power infrastructure approvals are in place, with civil works for power distribution expected to complete by August 2026, enabling site-wide testing and commissioning by October. The on-site laboratory, critical for accelerating test result turnaround and commercial feedstock valuation, is on track for dry lab completion in August and wet lab by October.

Feedstock Supply and Proprietary Processing Flowsheet Development

Metallium has secured binding contracts for approximately 4,000 tonnes per annum of PCB feedstock, covering about half of its Stage 1 nameplate capacity of 8,000 tpa. The company is advancing a proprietary PCB pre-processing flowsheet designed to maximise reactor throughput, improve economics, and recover additional value streams, including precious metals and strategic elements like gallium and germanium.

Recent testwork has demonstrated effective dry mechanical separation techniques, upgrading heterogeneous PCB feedstocks by concentrating copper-rich materials and rejecting lower-value fractions. Some commercial PCB batches under evaluation contain gold grades up to 700 g/t, highlighting significant embedded value.

Expanding Commercial Partnerships and Licensing Discussions

Commercial momentum is accelerating with expanded engagement across industry sectors such as AI, data centres, defence, and government. Metallium is progressing strategic sourcing collaborations with Indium Corporation for gallium and germanium feedstocks, while MOUs with Meteoric Resources and Element-USA have been extended for ongoing rare earth and red mud testwork.

Discussions on the company’s first potential technology licensing arrangement have advanced, offering a capital-light growth avenue alongside owned operations. However, no commercial terms have been agreed, and there is no certainty of a definitive agreement.

US Government Funding Pipeline and Strategic Collaborations

Metallium has identified over US$600 million in potential US and Canadian government grants, loans, and initiatives supporting critical minerals processing. The company is actively engaged in more than eight priority funding opportunities, including collaborations with Rice University, Battelle Memorial Institute, and Idaho National Laboratory, focused on expanding FJH applications and next-generation reactor development.

Additionally, Metallium entered a strategic collaboration with AmForge to develop critical minerals processing hubs in the US, with the Greenbrier project in West Virginia as the initial focus. While early stage and subject to approvals, this initiative could seed a network of processing hubs leveraging FJH technology.

Corporate Strength and Leadership Enhancements

The company ended the quarter with approximately A$65 million in cash, supporting ongoing technology development, commissioning, and commercial initiatives. Preparation for a potential NASDAQ listing is progressing, including a PCAOB audit and the search for an additional independent director.

Metallium also appointed Tim Cooper as Chief Financial Officer, bringing two decades of resources sector experience, and added metallurgical veteran Rod Lawry to its Technical Advisory Team, bolstering expertise ahead of commercial operations.

Next Steps and Outlook

Looking ahead, Metallium aims to commence multi-reactor chlorinated processing campaigns in the September quarter, continue optimisation of its integrated e-waste platform, secure further commercial agreements, and progress government funding applications. The company remains on track to start commercial e-waste processing and revenue generation in the first half of 2027, subject to permitting and commissioning success.

Meanwhile, Metallium’s technology development continues to demonstrate versatility beyond e-waste, with recent breakthroughs in direct upgrading of raw rare earth ore to high-value intermediates and successful testwork on germanium, platinum group metals, and other critical minerals. These advances could broaden the company’s commercial and licensing opportunities significantly.
