Metallium Advances Flash Joule Heating with Multi-Reactor Trial and Key US Contracts

Multi-Reactor Operation to Validate Scalability

Metallium Limited (ASX:MTM) is charging ahead with its Flash Joule Heating (FJH) technology, having completed more than 40 processing campaigns this quarter at its Gator Point Technology Campus in Texas. These trials, spanning feedstocks from printed circuit boards to catalytic converter scrap, have generated a rich data set that is actively informing improvements in throughput, recovery rates, and system stability.

The company’s next critical objective is to demonstrate multi-reactor operation by running three FJH units in parallel. This test, slated for the June quarter, will be a crucial proof point for scalability, confirming that the technology can maintain consistent performance and control as processing loads increase. Achieving this milestone would mark a transition from pilot-scale to a modular, deployable platform capable of expansion through additional units.

Securing the Commercial Value Chain

On the commercial front, Metallium has fortified its position with a decade-long offtake agreement with Indium Corporation, a major US refiner specialising in critical metals. This deal covers multiple metals extracted via FJH, including gallium and germanium; both vital for semiconductor and defence applications. Pricing is formula-linked to commodity markets, offering a transparent and market-responsive revenue stream.

Complementing this, the company’s US subsidiary secured a multi-year e-scrap supply contract with Glencore. This binding agreement guarantees feedstock supply during commissioning and early-stage operations, laying the groundwork for scaling up to multi-line processing at Gator Point. Discussions continue with Glencore to integrate feedstock supply and product offtake into a seamless commercial model.

Metallium’s strategy to diversify feedstock sources is underway, with multiple counterparties engaged in testing and evaluation phases. This pipeline includes a range of electronic waste and strategic metal streams, signalling confidence in FJH’s potential to address emerging supply chain needs for critical and precious metals.

Strengthening Execution and IP

To support its ambitious scale-up, Metallium appointed Hunt, Guillot & Associates as Owner’s Engineer for the Texas campus, expanding their role to cover EPCM functions. This move aims to de-risk and streamline project delivery, from construction completion through commissioning to operational readiness. Alongside this, the company has bolstered its internal technical and operational teams, including engineering, laboratory operations, and government affairs.

Intellectual property has also been enhanced through an expanded licence with Rice University, now covering additional recovery pathways for antimony, platinum group metals, and solar cell recycling. This broadens Metallium’s technology scope across high-value feedstocks.

Financial Position and Government Engagement

Metallium’s balance sheet is in robust shape following a A$75 million capital raising led by US investors, boosting cash reserves to approximately A$82 million at quarter-end. These funds are earmarked for commissioning, operational ramp-up, and ongoing technology development.

Engagement with US federal and state agencies; including EXIM and the Department of Commerce; continues to advance, aligning Metallium’s activities with domestic critical minerals processing priorities. Notably, the company recently completed Phase I of a US Department of War SBIR program, successfully demonstrating gallium recovery from semiconductor waste, a development that reinforces FJH’s strategic relevance and opens pathways for further government funding and collaboration.

Portfolio Optimisation and Focus

Consistent with a capital-light approach, Metallium farmed out its Pomme Rare Earths Project in Quebec via a joint venture with New Frontier Minerals Ltd. This deal enables value realisation from legacy exploration assets while retaining exposure to future royalties and the potential application of FJH technology in downstream processing.

Looking ahead, the company is targeting an ~8,000 tonnes per annum run-rate demonstration by late 2026, supported by ongoing commissioning and the execution of additional feedstock and offtake agreements. The upcoming multi-reactor trial will be a pivotal test of the platform’s commercial viability and scalability, setting the tone for future expansion.

The company’s progress reflects a focused pivot from exploration to technology commercialisation and operational execution, positioning Metallium as a potential key player in US critical metals supply chains. This trajectory follows the recent Metallium Validates Domestic Gallium Recovery milestone, underscoring the technology’s growing credibility within defence and strategic sectors.
