Australian Latrobe Magnesium demonstration plant construction progress exceeds 70%, first magnesium metal output expected in H2 2026 [SMM survey]

Latrobe Magnesium (ASX:LMG) announced on September 1 that construction of its Stage 1B magnesium demonstration plant in Victoria's Latrobe Valley, Australia, has reached 70% completion, with overall project construction accelerating and the project officially entering the final sprint toward commissioning. The project's core briquetting equipment has completed full-process installation and on-site acceptance testing, ready to begin phased commissioning at any time, while electrical systems, briquetting, and quicklime feeding auxiliary works are progressing steadily in tandem. Construction of the core reduction furnace area has advanced significantly, with key equipment including exhaust stacks and combustion piping all delivered and in place, and vacuum, noise reduction, and main support structures essentially completed. The project's safety compliance rate has exceeded 98% throughout, with no major safety incidents, and construction quality and schedule remain under control.

The project employs a proprietary process that utilizes fly ash solid waste from brown coal power plants to produce magnesium-based products, and has already achieved stable mass production of high-purity magnesium oxide, with mature front-end production capability in place. On the overseas cooperation front, leading US distributor Metal Exchange LLC has paid a $2 million prepayment to secure offtake rights for future magnesium ingot output from the plant, with downstream channels essentially locked in. The company plans to commence phased commissioning in the next reporting cycle, targeting first primary magnesium metal output in H2 2026. At this stage, the demonstration line is progressing smoothly, but the commercial-scale plant of 10kt capacity still requires financing and regulatory approvals, and will need further validation across technology, capital, and policy dimensions. In the near term, it can only contribute small-batch incremental magnesium supply outside China, with a longer timeline still required for scaled capacity release.
