Metallium (OTCQX:MTLMY) reported the successful completion of its first multi-unit Flash Joule Heating (FJH) campaign, running three units concurrently at its Texas technology facility.

Rhea-AI Summary

Metallium (OTCQX:MTLMY) reported the successful completion of its first multi-unit Flash Joule Heating (FJH) campaign, running three units concurrently at its Texas technology facility.

The campaign achieved 83% availability and about 100% utilization during active operation and, according to Metallium, delivered early evidence supporting the scalability of its low-carbon FJH platform for larger-scale deployment.

Metallium’s patented FJH technology targets recovery of critical and precious metals, including gallium, germanium, antimony, rare earths and gold, from feedstocks such as refinery scrap, e-waste and monazite. Its first commercial site is in Texas, operated by wholly owned subsidiary Flash Metals USA.

flash joule heating technical

"three Flash Joule heating Units concurrently at its technology development facility"

Flash joule heating is a process that uses a very brief, high-intensity electrical pulse to heat a material almost instantaneously, transforming its structure or purifying it in seconds. Think of it like an ultra-fast, high-energy toaster that changes raw material into a finished ingredient; for investors it matters because the technique can lower production time and energy costs, enable new materials or recycling routes, and create competitive manufacturing advantages.

e-waste technical

"metals from feedstocks such as refinery scrap, e-waste and monazite"

Electronic waste, or e-waste, is discarded electronic devices and components such as phones, computers, batteries and circuit boards — similar to throwing out an old appliance but with electrical parts and toxic materials. Investors care because e-waste creates regulatory, cleanup and disposal costs, potential liabilities, and reputational risk, while also presenting opportunities to recover value through recycling, refurbishment or materials reclamation that can affect a company’s costs and long‑term profitability.

rare earth elements technical

"high-value materials, including gallium, germanium, antimony, rare earth elements, and gold"

Rare earth elements are a set of 17 chemical metals used to make powerful magnets, batteries, catalysts and many tiny components inside electronics, renewable energy equipment and defense systems. They matter to investors because they are essential inputs for fast‑growing industries, and limited or concentrated supply can drive prices, create production bottlenecks or shift competitive advantage — like a factory running short of a specialized ingredient that halts output and affects profits.

HOUSTON, June 16, 2026 /PRNewswire/ -- Metallium Limited (ASX: MTM; OTCQX: MTMCF; OTCQX ADR: MTLMY) announced it has successfully completed operating three Flash Joule heating Units concurrently at its technology development facility in Texas. The multi-unit operations are a key part of the company's efforts to scale-up commercial development of the company's proprietary FJH technology platform.

"The successful sustained operation of three units simultaneously is a significant milestone in our commercialization effort and provides valuable confidence in the scalability of our technology, while generating important engineering data for future development programs," said Michael Walshe, managing director and CEO of Metallium.

"The campaign achieved 83% availability and approximately 100% utilization during active operation, exceeding our internal expectations for a first multi-unit commissioning campaign," he reported, adding that while the campaign utilized inert test media, "the operating rates demonstrated were broadly consistent with processing reactor feed volumes derived from several tons per day of incoming commercial feedstocks following preprocessing and upgrading. This is highly encouraging early evidence of the scalability of the platform and the suitability of the FJH architecture for larger-scale deployment," he affirmed.
