• First chlorine flash successfully completed on the FJH system
• Commissioning has commenced on schedule, consistent with prior guidance
• Represents the first integrated operation of the FJH-chlorination process at the Texas Technology Campus

Metallium Limited (ASX: MTM; OTCQX: MTMCF) has announced that commissioning has formally commenced at its Texas Technology Campus ('Gator Point') in Chambers County, Texas, following the successful and safe completion of the first chlorine flash using the Company's proprietary Flash Joule Heating (FJH) technology. This milestone represents a major step in de-risking the Company's U.S.-based critical-metals recovery platform, with commissioning activities progressing in parallel with ongoing construction works to support future expansion. The announcement highlights that a three-crucible FJH demonstration line has completed both dry and wet commissioning and is now fully operational, providing a dedicated R&D and scale-up platform alongside commissioning of the wider facility. Metallium has also secured a key environmental permit from the Texas Commission on Environmental Quality (TCEQ), enabling commissioning and operations to proceed. Commissioning activities are progressing across the broader Texas Technology Campus, including utilities, feedstock preparation, environmental control, and process control systems. Metallium's staged ramp-up strategy targets Stage-1 nameplate capacity of 8,000 TPA of inbound printed circuit board (PCB) E-waste by Q3 2026. The initial focus is on the recovery of gold, copper, silver, and tin from PCB feedstocks, with advanced planning underway for a future gallium/germanium process line.

Metallium is targeting Stage-1 throughput of 8,000 TPA of inbound printed circuit board (PCB) E-waste by Q3 2026, following progressive commissioning and modular expansion.

Metallium continues to advance toward commercial operations and industrial-scale deployment of its FJH technology in the United States and other priority jurisdictions, with the Texas Technology Campus underpinning the company's build-own-operate and technology-licensing strategy across urban mining, specialty and semiconductor metals, and rare earth and mineral-processing applications.
