Metallium Limited (ASX:MTM)

Metallium Limited announced a significant milestone with the successful completion of a 12-hour continuous Flash Joule Heating (FJH) reactor campaign at its Gator Point Technology Campus in Texas. This achievement validates the operational stability, automation systems, and repeatability of the reactor, significantly reducing technical and operational risks. The campaign demonstrated stable, repeatable operations over an extended duration, exceeding initial throughput expectations and validating reactor subsystems and procedures. These developments support Metallium's scale-up strategy based on a modular, parallel-reactor architecture aimed at expanding throughput by deploying multiple FJH reactors. The campaign also provided valuable operational data and insights into reactor throughput, feed handling, and control systems, contributing to ongoing technology refinement and future reactor development. Metallium's immediate focus is on transitioning from single-reactor operations to multi-reactor deployment, with plans for future 24-hour operating tests and continued optimisation activities to achieve its Stage-1 demonstration capacity targets.
