Latrobe Magnesium Receives US$15M Letter of Support for South Carolina Study
Key Takeaways
- Latrobe Magnesium (ASX: LMG) has received a US$15M non-binding Letter of Support from a large U.S.-based financial institution to fund the feasibility study for its proposed 50 ktpa magnesium metal plant in South Carolina.
- The LOS is subject to four material conditions — satisfactory due diligence, a matching US$15M from a confidential U.S.-based entity, regulatory and internal approvals, and execution of definitive agreements — none of which have been satisfied yet.
- The investment is structured into LMG's U.S. project subsidiary, not the ASX-listed entity directly, which is a key structural distinction for investors assessing dilution risk at the listed company level.
- LMG's South Carolina site has been selected with capacity for a Phase 2 expansion to 100 ktpa, meaning the feasibility study decisions made now shape the long-term ceiling of the project.
- LMG confirmed it will continue parallel negotiations with other parties for FS funding, land acquisition, and working capital, indicating the company is not treating this LOS as the sole path to a funded feasibility study.
US$15M letter of support backs LMG’s South Carolina feasibility study
Latrobe Magnesium Limited (ASX: LMG) has received a US$15M non-binding Letter of Support (LOS) from a large, U.S.-based financial institution to provide equity funding for the feasibility study (FS) for its proposed 50 thousand tonne per annum (ktpa) magnesium metal plant in South Carolina. The announcement, dated 17 September 2026, came two days after LMG’s original U.S. plant announcement on 15 September 2026.
The LOS is non-binding and subject to a series of conditions, meaning this is not secured or guaranteed funding. The counterparty invests alongside its clients across the U.S. and Asia-Pacific region and holds relationships with various U.S. Government entities.

Key terms and conditions investors need to know
The LOS comes with meaningful conditionality that investors should understand before drawing conclusions about the project’s funding status. LMG has acknowledged that conditionality directly in its announcement and confirmed it will continue parallel negotiations with other parties for FS funding, land acquisition, and working capital for the U.S. subsidiary.
Importantly, the investment is intended to be made into the U.S. project subsidiary, not into LMG’s ASX-listed entity directly.
| Condition | Detail | Status |
|---|---|---|
| Due diligence | Satisfactory completion of due diligence to the counterparty’s satisfaction; counterparty will have access to required materials | Pending |
| Matching US$15M financing | Conditional on LMG receiving an equivalent US$15M of financing from a specified, confidential U.S.-based entity | Pending |
| Regulatory and internal approvals | Receipt of all required internal and regulatory approvals | Pending |
| Definitive agreements | Negotiation, execution and delivery of definitive written agreements and other documentation for the investment | Pending |
The identity of the counterparty and the specified matching entity are both confidential. LMG has not disclosed either party publicly.
What is a magnesium feasibility study and why does funding it matter?
A feasibility study (FS) is the critical engineering and economic assessment that sits directly before a project can proceed to a construction decision. It goes beyond a pre-feasibility study (PFS), which provides a broader, higher-level assessment of whether a project is worth pursuing. The FS drills into the detail: process design, capital cost estimates, operating cost models, infrastructure requirements, and project financing structures. Without a completed FS, a project cannot move to construction.
For LMG’s South Carolina plant, a funded FS at the 50 ktpa scale is the gateway to everything that follows. The site itself has been selected with capacity for a future Phase 2 expansion to 100 ktpa, which means the decisions made at the FS stage shape the long-term ceiling of the project.
Magnesium sits in a structurally attractive demand position. It carries the best strength-to-weight ratio of all common structural metals and is used across the automotive, aerospace, defence, medical, and electronics industries. As manufacturers under sustained pressure to reduce component weight, magnesium’s role in lightweighting is well understood by industrial buyers.
LMG’s extraction process adds an ESG dimension that differentiates it from conventional magnesium producers. The company’s world-first patented process recovers magnesium metal from industrial by-products, including ferronickel slag, avoiding landfill, generating zero waste and tailings, and positioning LMG as a low CO₂ emitter. That process profile is increasingly relevant to offtake partners and financiers operating under sustainability mandates.

Where LMG’s U.S. project stands and what comes next
The South Carolina feasibility study is one piece of a broader project pipeline that LMG is advancing across three countries. Here is where each asset currently sits:
- South Carolina, USA (50 ktpa plant): Feasibility study stage; US$15M non-binding Letter of Support received, subject to the conditions outlined above. Site has capacity for a future Phase 2 expansion to 100 ktpa.
- Latrobe Valley, Victoria (Demonstration Plant): First half commissioned and producing sustained magnesium oxide and other saleable by-products. 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 U.S. market through distribution partner Metal Exchange LLC.
- Latrobe Valley, Victoria (10 ktpa Commercial Plant): Development rights held; currently on hold.
- Sarawak, Malaysia (International ‘Mega’ Plant): Up to 100 ktpa planned capacity 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 adds further feedstock optionality to the company’s industrial by-product recovery model, complementing the ferronickel slag inputs central to the South Carolina and Sarawak plants.
LMG has confirmed it will continue to provide regular market updates as the U.S. project progresses.
The LOS, conditional as it is, represents a notable signal. A large U.S.-based financial institution with government relationships has indicated a willingness to commit US$15M in equity to fund the FS for LMG’s South Carolina plant. That level of institutional interest, even at a non-binding stage, reflects external validation of the company’s approach to securing project-level financing through a dedicated U.S. subsidiary structure. Whether it converts to a binding commitment depends on the conditions being satisfied, and investors should track those milestones as they develop.
