Latrobe Magnesium Produces 20 Tonnes High-Grade Magnesium Oxide Successfully

Latrobe Magnesium Achieves Major Milestone with 20 Tonnes of High-Grade Magnesium Oxide

Latrobe Magnesium Limited (ASX: LMG) has successfully produced approximately 20 tonnes of Latrobe Magnesium high-grade magnesium oxide from its demonstration plant, marking a significant step toward full magnesium metal production in the second half of 2026. This achievement represents a crucial validation of the company's patented extraction process.

The company's world-leading demonstration plant in Victoria's Latrobe Valley achieved this milestone through two weeks of continuous production. Assay results confirmed the Latrobe Magnesium high-grade magnesium oxide meets quality standards, with X-ray diffraction analysis revealing magnesium compounds at approximately 90%.

This positions the company to transition toward its ultimate goal of magnesium metal production. The patented process transforms industrial ash waste from brown coal power generation into valuable magnesium products, with first metal production targeted for the second half of 2026.

Production Quality Exceeds Expectations

The mineralogy analysis of the Latrobe Magnesium high-grade magnesium oxide production demonstrates impressive results that align with technical requirements. Furthermore, the quality metrics provide confidence for the next phase of development.

The total magnesium compounds reached approximately 90%, which matches the purity levels previously used in successful CSIRO test work. Importantly, the presence of 5% calcium oxide (burnt lime) is actually beneficial, as it's used in the briquettes required for the magnesium metal reduction process.

This component could potentially reduce operating costs in future metal production. In addition, the company expects to eliminate the 5.5% calcium chloride component through minor adjustments to its patented hydromet processing conditions, which could push magnesium compound concentrations above 95%.

"The positive results from these assays and continuous Demonstration Plant operations satisfies the LMG Board that its processes and MgO production output meet the requisite requirements to transition to Mg metal production."

Understanding Magnesium Oxide: The Foundation of Metal Production

Magnesium oxide (MgO) serves as the critical intermediate product in magnesium metal production. For instance, this milestone is significant because it demonstrates proof of process and validates the feedstock quality required for commercial operations.

The 20-tonne production run over two weeks indicates the plant can sustain operations, a crucial requirement for commercial viability. Moreover, magnesium oxide acts as the refined raw material that gets processed further into pure magnesium metal through reduction processes.

Why This Matters to Investors

The successful production of Latrobe Magnesium high-grade magnesium oxide provides several key benefits for investors:

• Process Validation: Demonstrates the company's patented technology works at industrial scale
• Quality Assurance: Confirms the feedstock can produce commercial-grade intermediate products
