LMG has completed the first half of a Demonstration Plant in Victoria's Latrobe Valley which has now achieved sustained production of magnesium oxide and other saleable by-products, with the full plant, including magnesium metal production, expected to be commissioned in the second half of 2026. 100% of the Demonstration Plant's magnesium metal is allocated to the US market through LMG's distribution partner, Metal Exchange LLC. LMG is proposing to develop a 50 ktpa primary magnesium metal plant in South Carolina, USA, using ferronickel slag feedstock, with site capacity for a future Phase 2 expansion to 100 ktpa. LMG also holds development rights for a 10 ktpa Commercial Plant in Victoria's Latrobe Valley (currently on hold) and for an International ‘Mega’ Plant in the state of Sarawak, Malaysia, with potential capacity up to 100 ktpa, via its wholly owned subsidiary company Latrobe Magnesium Sarawak Sdn Bhd. LMG has completed the first phase (PFS-A) of a pre-feasibility study using ferronickel slag feedstock. Magnesium has the best strength-to-weight ratio of all common structural metals and is increasingly used in the automotive, aerospace, defence, medical and electronics industries. LMG's projects are at the forefront of ESG best-practice by recycling industrial by-products, avoiding landfill, generating zero waste and tailings, encouraging a circular economy, and by being a low CO₂ emitter.
