Lithium Universe Unveils $787 Million NPV Brownsville Refinery Plan

Brownsville Refinery Targets North American Lithium Conversion Gap

Lithium Universe Limited (ASX:LU7) has released a Pre-Feasibility Study (PFS) for its Brownsville Lithium Carbonate Refinery in Texas, projecting a pre-tax Net Present Value (NPV) of approximately US$787 million at an 8% discount rate. The project boasts a 21% internal rate of return (IRR) and a payback period of under four years, underpinned by conservative lithium pricing assumptions that remain below current spot prices.

The refinery is designed to produce up to 18,270 tonnes per annum of battery-grade lithium carbonate, leveraging proven technology from the Jiangsu Lithium Carbonate Plant in China. This approach aims to mitigate the technical and operational risks that have plagued many recent lithium conversion projects globally. The Brownsville facility intends to serve the rapidly expanding North American electric vehicle (EV) and energy storage system (ESS) markets, addressing a critical gap in domestic lithium chemical production capacity.

Strategic Location and Supply Chain Advantages

Located at the Port of Brownsville, the refinery benefits from deep-water port access, established industrial infrastructure, and proximity to emerging battery and EV manufacturing hubs along the US Gulf Coast. The site’s lower labour costs, estimated at 24% below Québec levels, and access to competitively priced natural gas and reagents contribute to an operating cost advantage over comparable Canadian projects.

Lithium Universe has secured a binding 10-year offtake agreement with Norah Mining Limited for up to 80,000 tonnes per annum of spodumene concentrate from Nigeria, providing a discounted feedstock supply that strengthens project margins. The logistics advantage of shorter shipping routes from West Africa to Texas further enhances the refinery's competitiveness.

Robust Economics Despite Elevated Capital Costs

The PFS estimates total capital expenditure at approximately US$607 million, including a substantial contingency allowance of US$130 million to buffer against current geopolitical and construction market volatility. This contingency is more than double that of the prior Bécancour DFS, reflecting a conservative risk management approach.

Operating costs are estimated at US$3,566 per tonne of lithium carbonate (excluding spodumene feedstock), representing a reduction of about US$365 per tonne compared to the Bécancour project. This cost efficiency, combined with the discounted feedstock and favourable location, results in a gross margin of approximately 42% or US$8,822 per tonne of product.

Proven Jiangsu Technology and Risk Mitigation

The refinery’s design replicates the proven Jiangsu lithium carbonate refinery, which has operated successfully for over a decade. This “copy-and-paste” engineering model, supported by Hatch Ltd. as the engineering partner, reduces technical uncertainty and accelerates project timelines. The conventional sulphuric acid leach process employed contrasts with newer, less proven alkaline pressure leach technologies, which have encountered operational challenges elsewhere.

Metallurgical testing confirms the refinery’s ability to process diverse spodumene concentrates from Australia, Brazil, and Africa, ensuring feedstock flexibility. The project also incorporates a Zero Liquid Discharge (ZLD) system, simplifying environmental permitting and reducing wastewater impacts.

Next Steps and Financing Strategy

Lithium Universe plans to advance to a Definitive Feasibility Study (DFS), secure long-term lease arrangements with the Port of Brownsville, and progress permitting and environmental approvals. The company is actively engaging with potential strategic partners and financiers, aiming to offer up to a 49% equity stake to investors with spodumene supply or downstream interests to create a vertically integrated lithium supply chain.

Federal and state incentives under the US Inflation Reduction Act, Department of Energy grants, and Department of Defense critical minerals funding may provide additional support, although these have not been factored into the current financial model.

Closing the North American Lithium Supply Chain Gap

The Brownsville refinery is positioned to play a pivotal role in reducing North America’s reliance on imported lithium chemicals, predominantly sourced from China. With North American lithium demand forecast to grow elevenfold by 2040, driven by EV and ESS market expansion, domestic refining capacity is critical to supply chain security and localisation goals.

The project’s robust economics, proven technology base, and strategic location collectively offer a compelling case for investment in the region’s emerging lithium chemical sector.
