ABM Utah Lithium Project Targets Direct Extraction and Magnesium Output

ABM

ABM Utah lithium project plans could add a new US domestic source of lithium carbonate equivalent and magnesium if feasibility work supports development. American Battery Materials is assessing a direct lithium extraction facility in Utah tied to its Lisbon Valley project.

The ABM Utah lithium project is designed to produce 10,000 t/yr of lithium carbonate equivalent. The proposed facility would also produce 20,000 t/yr of magnesium ingots, giving the project a broader critical minerals profile.

The ABM Utah lithium project is located in the Paradox Basin, which straddles southern Utah and Colorado. The region sits in a historic seabed and contains lithium, magnesium, bromine, potash and potassium.

Historical data from Lisbon Valley show lithium values ranging from 81-500ppm. The next test is whether those values can support a commercial direct lithium extraction operation with competitive recovery, cost and product quality.

Direct Lithium Extraction Could Support US Battery Supply

Direct lithium extraction is becoming more important as the US seeks domestic lithium supply without relying only on hard-rock mining or traditional evaporation routes. DLE can potentially recover lithium from brines faster and with a smaller surface footprint.

For ABM, the strategic opportunity is to convert Lisbon Valley brine resources into battery-linked lithium carbonate equivalent. A 10,000 t/yr project would not dominate the market, but it could become a useful domestic supply source if successfully developed.

The project also fits US policy priorities. Washington is trying to secure more lithium, magnesium and other critical materials for batteries, defence, energy storage and manufacturing.

However, DLE projects remain technically demanding. Brine chemistry, recovery rates, reagent consumption, water handling, scaling, impurity control and operating cost will determine whether the Lisbon Valley project can move beyond feasibility.

Product qualification will also matter. Battery customers need consistent lithium carbonate quality, and that requires reliable processing from brine extraction through purification and final product production.

Magnesium Adds Strategic Value to the Project

The planned magnesium output gives the project an additional industrial angle. Magnesium ingots are used in aluminium alloys, die casting, lightweight components and specialty applications.

US magnesium supply has strategic relevance because magnesium supports automotive lightweighting, aerospace materials and defence-linked manufacturing. A domestic source could help reduce exposure to imported material.

The Paradox Basin’s broader mineral endowment also strengthens the project’s optionality. Lithium, magnesium, bromine, potash and potassium create potential for multi-product development, depending on commercial recovery and market conditions.

Multi-product projects can improve economics if by-products are saleable and processing flows are integrated efficiently. However, they can also add complexity because each product requires its own specification, market and operating route.

For ABM, feasibility work will need to prove both the lithium and magnesium business cases. Investors and customers will watch the project’s recovery assumptions, capital cost, permitting path and development timeline.

If successful, the Lisbon Valley project could support a more diversified US critical minerals base. Its importance lies not only in lithium supply, but in the possibility of linking battery materials with magnesium production from one regional resource system.

The Metalnomist Commentary

ABM’s Utah plan shows how US lithium projects are increasingly being framed as multi-mineral supply platforms. The key question is whether direct lithium extraction can turn Paradox Basin brines into qualified lithium carbonate and meaningful magnesium output at commercial cost.
