Latrobe Magnesium Limited has successfully produced around 20 tonnes of high-grade Magnesium Oxide from its Hazelwood North Demonstration Plant, paving the way for magnesium metal production later this year.
- Produced ~20 tonnes of high-grade Magnesium Oxide with ~90% Mg compounds
- Demonstration Plant ready to transition to magnesium metal production in 2H 2026
- Minor process tweaks expected to boost MgO purity above 95% and reduce costs
- Installation and commissioning of metal production underway post-shutdown
- Plans for commercial plant with 10,000 tonnes per annum capacity and international expansion
Demonstration Plant Delivers Promising Magnesium Oxide Output
Latrobe Magnesium Limited (ASX:LMG) has announced a significant milestone in its development journey, successfully producing approximately 20 tonnes of high-grade Magnesium Oxide (MgO) from its Hazelwood North Demonstration Plant. Over a continuous two-week production period, the plant achieved Mg compound concentrations around 90%, meeting the company’s quality benchmarks.
This achievement confirms the robustness of Latrobe’s patented extraction process, which utilises industrial ash waste from brown coal power generation in Victoria’s Latrobe Valley. The company’s assay results, based on X-ray diffraction analysis, also revealed the presence of calcium oxide and calcium chloride, compounds that play a role in the magnesium metal production process.
Transitioning to Magnesium Metal Production
Encouraged by the quality and consistency of the MgO output, Latrobe’s board has approved the transition to magnesium metal production. The Demonstration Plant has now entered a planned shutdown phase to facilitate the installation and commissioning of the magnesium metal production component, with first metal expected in the second half of 2026.
Minor adjustments to the hydrometallurgical processing are anticipated to eliminate calcium chloride impurities and increase MgO purity beyond 95%. These refinements are expected to reduce consumable costs, particularly by lowering the need for additional calcium oxide during briquette formation for metal reduction.
Strategic Growth and Market Positioning
Latrobe Magnesium is positioning itself as a key player in the magnesium market, with plans for a commercial-scale plant capable of producing 10,000 tonnes of refined magnesium metal annually. This facility will leverage proximity to feedstock, infrastructure, and skilled labour in Victoria’s coal power precinct.
Beyond Australia, the company is advancing an international ‘Mega’ Plant project in Sarawak, Malaysia, targeting a production capacity of 100,000 tonnes per annum. This expansion underscores Latrobe’s ambition to meet growing demand for magnesium, a metal prized for its exceptional strength-to-weight ratio and applications across automotive, aerospace, medical, and electronics sectors.
Sustainability and Circular Economy Focus
Latrobe Magnesium’s operations exemplify environmental, social, and governance (ESG) best practices by recycling industrial waste that would otherwise be landfilled. The company’s low-carbon emission process and circular economy approach align with increasing market and regulatory emphasis on sustainable materials production.
As the company moves towards commercial magnesium metal production, investors and industry watchers will be keen to monitor the impact of process optimisations on cost efficiency and product quality, as well as the timeline for plant commissioning and metal output.
Bottom Line?
Latrobe Magnesium’s successful MgO production sets the stage for a pivotal shift to metal output, with market implications for supply and sustainability.
Questions in the middle?
- Will the planned process adjustments fully eliminate calcium chloride and boost MgO purity as expected?
- How will the transition to metal production affect operational costs and margins?
- What are the timelines and risks associated with the commissioning of the commercial and international plants?
