Latrobe Magnesium Receives US$15M Support Letter for South Carolina Study
Key Takeaways
- Latrobe Magnesium received a US$15M non-binding Letter of Support from a large U.S.-based financial institution just two days after announcing its South Carolina 50 ktpa magnesium plant project on 15 September 2026.
- The LOS is conditional on LMG securing an equivalent US$15M from a separate confidential U.S.-based entity, meaning the full US$30M feasibility study funding package is not yet confirmed.
- The South Carolina site has been selected with capacity for a Phase 2 expansion to 100 ktpa, embedding future scale into the project's land footprint from the outset.
- LMG's Demonstration Plant in the Latrobe Valley is progressing toward full commissioning in H2 2026, with 100% of magnesium metal output already allocated to the U.S. market via distribution partner Metal Exchange LLC.
- Parallel negotiations for feasibility study funding, land acquisition, and working capital for the U.S. subsidiary are ongoing with multiple parties, indicating the LOS is one component of a broader capital formation process.
LMG receives US$15M non-binding letter of support for South Carolina feasibility study
Latrobe Magnesium Limited (ASX: LMG) announced on 17 September 2026 that it has received a US$15M non-binding Letter of Support (LOS) from a large U.S.-based financial institution, intended to provide equity funding for the feasibility study (FS) of its 50 thousand tonne per annum (ktpa) magnesium metal plant in South Carolina, USA.
The announcement follows LMG’s earlier disclosure on 15 September 2026 that it would pursue the U.S. 50 ktpa project, with this LOS arriving just two days later. The investment is intended to be made in LMG’s U.S. project subsidiary, though the LOS carries significant conditionality that investors should understand clearly before drawing conclusions.

Why magnesium and why the U.S. market — the investment case explained
Magnesium holds a distinctive position among structural metals: it has the best strength-to-weight ratio of all common structural metals, making it increasingly sought after in the automotive, aerospace, defence, medical, and electronics industries. As manufacturers look to reduce weight without sacrificing strength, magnesium demand continues to expand across these sectors.
A 50 ktpa plant in South Carolina positions LMG directly alongside these end markets. The U.S. site uses ferronickel slag as feedstock (ferronickel slag is an industrial by-product from nickel refining operations) and has been selected with site capacity for a future Phase 2 expansion to 100 ktpa.
A feasibility study is a detailed technical and financial assessment that determines whether a project can be built and operated profitably at a commercial scale. It typically covers engineering design, capital cost estimates, operating cost projections, and market assumptions. Securing funding to complete an FS is a material step in project development because it is the gateway between early-stage planning and a Final Investment Decision.
LMG’s underlying competitive advantage is its world-first patented extraction process, which recovers magnesium metal, cementitious material, and other products from industrial by-products such as brown coal ash and ferronickel slag. This process also underpins the company’s ESG credentials: LMG’s projects recycle industrial by-products, avoid landfill, generate zero waste and tailings, and operate as a low CO₂ emitter.

Where LMG stands and what comes next
The U.S. 50 ktpa plant sits within a broader multi-project portfolio. Here is where each asset currently stands:
- Demonstration Plant, Latrobe Valley, Victoria — The first half has been commissioned, producing sustained magnesium oxide and other saleable by-products. Full plant commissioning, including magnesium metal production, is expected in the second half of 2026. 100% of Demonstration Plant magnesium metal is allocated to the U.S. market through distribution partner Metal Exchange LLC.
- 50 ktpa Commercial Plant, South Carolina, USA — The subject of this announcement. Feasibility study funding is being pursued; the LOS represents early-stage institutional interest, subject to conditions.
- 10 ktpa Commercial Plant, Latrobe Valley, Victoria — Development rights held; currently on hold.
- Malaysia Mega Plant, Sarawak — Planned capacity of up to 100 ktpa via wholly owned subsidiary Latrobe Magnesium Sarawak Sdn Bhd. The first phase of a pre-feasibility study (PFS-A) using ferronickel slag feedstock has been completed.
LMG’s coal fly ash project development in the Latrobe Valley sits alongside the South Carolina plant as part of the same patented extraction platform, applying the same process logic to brown coal ash feedstock rather than ferronickel slag.
LMG has confirmed it will continue to provide regular market updates as the U.S. Project progresses, and parallel negotiations with other parties for FS funding, land acquisition, and working capital are ongoing.
The LOS represents early-stage validation from an institutional counterparty with U.S. government relationships, but investors should weigh its conditionality carefully. Until due diligence is complete, the equivalent US$15M from the specified confidential entity is confirmed, and definitive agreements are executed, this remains a non-binding expression of intent rather than committed capital.
