flash joule heating technical

"Metallium Limited ... announced the successful completion of a 12-hour continuous Flash Joule Heating (FJH) reactor campaign"

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

"technology is being commercialized at the facility as an e-Waste processing platform"

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

"including gallium, germanium, antimony, rare earth elements, and gold from feedstocks"

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.

monazite technical

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

Monazite is a naturally occurring mineral that concentrates rare earth elements — the metals used in electronics, permanent magnets and clean-energy technologies — often mixed with small amounts of radioactive thorium. For investors it matters because monazite is a primary feedstock for producing those valuable metals, so its availability, grade and the extra cost and regulation tied to its radioactivity can sharply affect mining economics and supply risk. Think of it as a fruit bowl with very valuable fruit tucked next to prickly thorns.

Operational Stability, Automation Systems and Repeatability Validated Prior to Upcoming Multi-Reactor Operations at Company's First Commercial Facility

HOUSTON, May 12, 2026 /PRNewswire/ -- Metallium Limited (ASX: MTM; OTCQX: MTMCF; OTCQX ADR: MTLMY) announced the successful completion of a 12-hour continuous Flash Joule Heating (FJH) reactor campaign at its Gator Point Technology Campus in Chambers County, Texas.

Stable, repeatable and controlled operation of Metallium's "Generation-1" automation systems and operating procedures were successfully completed during the 12-hour period ahead of planned multi-reactor deployment.

"These results materially reduce technical and operational scale-up risks as Metallium advances toward multiple FJH reactors operating simultaneously," said Michael Walshe, managing director and CEO of Metallium.

Flash Joule Heating, the company's proprietary technology, is being commercialized at the facility as an e-Waste processing platform. This specific use of the technology is a low-carbon, high-efficiency approach to recovering critical and precious metals from e-Waste. This process is at the forefront of eMining, which has taken on greater importance as the United States recognizes the need to harness critical minerals and metals domestically.

Metallium's scale-up strategy is based on a modular parallel-reactor architecture, where throughput expansion is achieved through the operation of multiple FJH reactors united under an integrated control framework. "The successful completion of extended-duration single reactor operations represents an important prerequisite step as we move into the next phase of development," explained Walshe. He added the campaign also generated valuable operating data and early optimization insights across reactor throughput, feed handling, instrumentation, control systems and broader plant integration activities that support ongoing technology refinement and future reactor development.

Metallium Limited (https://www.metalliuminc.com) the pioneer of a low-carbon, high-efficiency approach to recovering critical and precious metals from mineral concentrates and high-grade waste streams. The company's patented Flash Joule Heating (FJH) technology enables the extraction of high-value materials, including gallium, germanium, antimony, rare earth elements, and gold from feedstocks such as refinery scrap, e-waste and monazite. Metallium's first commercial site is located in Texas and owned via its wholly owned subsidiary, Flash Metals USA Inc.
