Highlights

Three FJH reactors operated together during a September 2026 chlorination campaign.
Preliminary PCB trials reported recoveries above 90% for several metals into mixed metal-bearing streams.
An initial USD 500,000 services payment was received under a development agreement.
Cash and cash equivalents totalled AUD 50.7 million at 30 September 2026.

Metallium Limited (ASX:MTM) is developing Flash Joule Heating (FJH) technology for recovering metals from electronic waste and other feedstocks. Its Gator Point Technology Campus in Texas supports reactor testing, engineering and planned commercial processing. During the September 2026 quarter, Metallium completed a reactive multi-reactor test campaign and generated technology-services revenue. The next challenge is to convert these development milestones into a validated, repeatable processing system capable of delivering qualified products at scale.

September Multi-Reactor Campaign Completed

Metallium Limited (ASX:MTM) reported that three FJH reactors operated simultaneously across a 12-hour campaign using spent automotive catalytic converter feedstock. The work represented a progression from earlier inert testing to reactive chlorination conditions. It generated operational observations and samples to refine feed preparation, reactor configuration and Downstream collection. The reported campaign comprised 12 test cycles and approximately 75 kilograms of nominal feed, rather than sustained commercial throughput. The company also reported zero lost-time injuries during the campaign. These achievements support engineering development but do not demonstrate that a complete industrial processing route has reached commercial operating conditions.

PCB Recovery Testing and Product Validation

The company has identified processing printed circuit boards (PCBs) recovered from electronic waste as its immediate commercial priority. Preliminary batch testwork indicated recoveries above 90% for copper, gold, silver, tin and palladium into mixed metal-bearing streams. Metallium Limited (ASX:MTM) cautioned that more testwork, reconciliation and downstream product qualification are required. Recovery into intermediate streams should not be confused with sale of refined metals or demonstrated plant profitability. The company is preparing an implementation plan assessing standalone modules with a proposed annual PCB throughput of 8,000 tonnes each. The proposed scale remains subject to technical assessment, commissioning and board approval; it is not an existing production rate.

Services Revenue and Available Funding

Metallium Limited (ASX:MTM) received an initial USD 500,000 payment from Environmental Clean Technologies under a 12-month research and engineering agreement. The arrangement provides for cash consideration of up to USD 1.4 million, subject to its terms. The company said the platform produced material consistent with MXene formation during the first two development runs, with further characterisation needed. Gator Point therefore has a paid technology-services activity separate from prospective PCB metal-product sales. At 30 September 2026, cash and cash equivalents were AUD 50.7 million. The company also disclosed a non-binding commercial framework to explore feedstock, offtake and financing arrangements. Non-binding discussions are not committed finance or guaranteed supply.

Commercial Timeline and Execution Risks

In its November AGM material, Metallium Limited (ASX:MTM) outlined plans for staged PCB installation, commissioning and initial product sales in the first half of calendar 2027, with a possible ramp-up thereafter. Timing depends on equipment deployment, product specifications and customer acceptance. Further plant optimisation, regulatory requirements, feedstock variability and financing decisions may affect the sequence. The company is also advancing its FJH Nexus development programme and intellectual property protection. These longer-term initiatives should be distinguished from Gator Point's immediate PCB processing work. Commercial Economics remain to be established through integrated operation and reliable saleable product quality.

Key Insights

Metallium has advanced from isolated technology demonstrations to coordinated reactor testing and has received paid services revenue. Yet the proposed PCB processing Business remains dependent on validation, equipment deployment, qualified output and execution of commercial arrangements. The September cash position supports continuing development without proving the economics of future operations.
