Lithium Universe Texas Refinery PFS Delivers US$787M NPV Beating Canada Project
Key Takeaways
- The Brownsville PFS delivers a pre-tax NPV of approximately US$787 million at an 8% discount rate and a 21.0% IRR, roughly 10% higher than the Bécancour DFS result of US$718 million on identical price assumptions.
- Operating costs excluding spodumene are estimated at US$3,566/t — approximately US$365/t lower than Bécancour — driven by 24% lower Texas labour costs, cheaper natural gas and soda ash, and a 7.5% feedstock discount under the Nigeria offtake agreement.
- The base-case financial model uses US$20,970/t for battery-grade lithium carbonate, materially below current spot prices of approximately US$24,000–27,000/t, meaning the published economics represent a deliberately conservative floor.
- A binding 10-year Definitive Offtake Agreement with Norah Mining Limited of Nigeria underpins up to 80,000 tpa of SC6 spodumene concentrate at a 7.5% market discount, covering approximately 60% of the refinery's feedstock requirements.
- The company is targeting up to a 49% equity interest sale to strategic investors — specifically spodumene producers — to fund the estimated US$620–650 million required to advance the project, with no financing arrangements currently in place.
Brownsville PFS delivers stronger economics than Bécancour as lithium prices recover
Lithium Universe (ASX: LU7) has published the results of its Pre-Feasibility Study (PFS) for the proposed Brownsville Lithium Carbonate Refinery in Texas, delivering a pre-tax Net Present Value (NPV) of approximately US$787 million at an 8% discount rate and a pre-tax Internal Rate of Return (IRR) of approximately 21.0%, with a payback period of 3.9 years. Using identical price assumptions to those applied in the previously completed Bécancour Definitive Feasibility Study (DFS), the Brownsville result represents roughly a 10% increase in pre-tax NPV compared with Bécancour’s US$718 million, allowing a direct project-to-project comparison.
The financial model is built on conservative long-term assumptions of US$1,170/t for spodumene concentrate (SC6) and US$20,970/t for battery-grade lithium carbonate. Current spot battery-grade lithium carbonate prices are sitting at approximately US$24,000–27,000/t, materially above the study’s price floor, which means the base-case economics reflect a deliberately cautious starting point.
At full production capacity, the project is expected to generate annual revenues of approximately US$383 million and annual EBITDA of approximately US$161 million (versus US$148 million at Bécancour), with a gross margin of approximately 42% (versus 39% at Bécancour).
Management
“The Brownsville Pre-Feasibility Study demonstrates that Lithium Universe’s strategy of replicating the proven Jiangsu lithium refinery model can deliver stronger economics than the previously completed Bécancour Definitive Feasibility Study, while maintaining the same conservative long-term lithium pricing assumptions. Importantly, the study has retained the identical forecast prices of US$1,170/t for SC6 spodumene concentrate and US$20,970/t for battery-grade lithium carbonate used in the Bécancour DFS, allowing investors to make a true ‘apples-to-apples’ comparison between the two projects…”

Why Brownsville outperforms Bécancour on costs
Lower operating costs drive the improvement
Total operating costs (excluding spodumene) are estimated at approximately US$3,566/t of lithium carbonate, compared with US$3,931/t at Bécancour, a reduction of approximately US$365/t. The five primary cost advantage drivers are:
- Labour costs in Texas are estimated to be approximately 24% lower than in Québec
- Lower natural gas and soda ash costs relative to eastern Canada
- Discounted spodumene feedstock via the proposed Nigeria offtake arrangement, at a 7.5% discount to market pricing
- Shorter shipping route from Nigeria to Brownsville compared with shipping into the St. Lawrence Seaway
- Cold-climate infrastructure requirements largely eliminated, reducing long-term operating complexity
These advantages are partially offset by higher electricity costs in Texas, but the presentation notes that overall project economics remain stronger than the Bécancour case.
Capital cost and contingency — a conservative approach
Total CAPEX is estimated at approximately US$607 million (versus US$549 million at Bécancour), at a Class 3 accuracy range of ±30%. The increase is dominated by a substantially larger contingency allowance, reflecting a deliberate and disciplined approach to project risk management given current construction market conditions.
Direct costs are estimated at approximately US$380.7 million. The contingency alone stands at approximately US$130 million, compared with just US$51 million in the Bécancour DFS — an increase that accounts for geopolitical uncertainty, equipment pricing volatility, and the transition from DFS-level to PFS-level study definition. Approximately US$18 million of cold-climate infrastructure from the Bécancour design has been retained within the estimate as a conservative contingency allowance, representing a potential future capital cost reduction opportunity as detailed engineering advances.

Closing North America’s lithium conversion gap — why location matters
North American lithium demand is forecast to grow approximately 11-fold by 2040, rising from 30kt LCE in 2025 to 334kt LCE, according to the International Lithium Association (ILiA). Despite this trajectory, more than 90% of global LFP battery manufacturing capacity currently sits in China, leaving the region heavily dependent on imported lithium chemicals.
The Brownsville refinery is designed to address this conversion gap directly. The proposed site is a 35-acre parcel within the Port of Brownsville Business Park on Chemical Road, a deep-water port capable of receiving vessels carrying up to 30,000 tonnes of spodumene concentrate. The port’s location provides direct access to African, Brazilian, and North American feedstock supply routes, while serving emerging battery and EV manufacturing hubs across Texas and the Gulf Coast.
The proximity of Tesla’s lithium hydroxide refinery near Corpus Christi, approximately 250km to the north-northeast, signals Texas as an emerging North American lithium processing corridor. Potential federal and state incentives — including Department of Energy (DOE) grants and loans, Inflation Reduction Act (IRA) tax benefits, Department of Defense (DoD) critical minerals funding, and Texas-specific incentives such as property tax abatements and workforce grants — could further strengthen the project’s competitive position, though no financing arrangements are currently in place.
A binding 10-year Definitive Offtake Agreement (DOA) with Norah Mining Limited (NML) of Nigeria underpins feedstock access. Under the DOA, NML is expected to supply up to 80,000 tpa of SC6 spodumene concentrate at a 7.5% discount to market pricing, which is expected to cover approximately 60% of the refinery’s spodumene requirements, subject to the supplier achieving successful start-up and planned operational parameters.
What makes the Jiangsu “copy-and-paste” model a lower-risk path to production
LU7’s central technological argument is that replicating a commercially proven refinery design substantially reduces the execution risk that has afflicted other western lithium refinery projects. The rationale rests on five points:
- The Jiangsu reference plant: In 2012, Hatch Ltd. engineered and constructed a lithium carbonate refinery in Jiangsu Province, China, for Galaxy Resources Limited, under the leadership of Iggy Tan and Dr Jingyuan Liu. Today, the Jiangsu operation is producing approximately 20,000 tpa of high-purity battery-grade lithium carbonate and is recognised for producing some of the highest-quality lithium carbonate products in the market.
- Proven technology, not unproven innovation: The refinery uses a conventional sulphuric acid leach process with origins dating to the 1950s — the established commercial technology for spodumene conversion globally. This contrasts with alkaline pressure leach (APL) processes, which LU7 regards as relatively unproven at commercial scale and potentially susceptible to scaling and operational blockages.
- Western refinery failures as context: High-profile commissioning difficulties at Tianqi Kwinana and Albemarle Kemerton in Western Australia, as well as Nemaska Lithium in Canada, demonstrate the real cost of deploying unproven technology or operating without sufficient lithium conversion expertise.
- Same EPCM partner re-engaged: Hatch Ltd. has again been selected as the Engineering, Procurement and Construction Management (EPCM) contractor for Brownsville, providing continuity of technical knowledge and access to the same supplier network used at Jiangsu.
- Three provisional patents filed: The company has submitted three provisional patent applications, collectively known as the Brownsville Patents, protecting proprietary process improvements in impurity removal, the purification section, and sodium sulphate recovery.
The plant is designed to produce up to 18,270 tpa of battery-grade lithium carbonate (greater than 99.5% Li₂CO₃), processing approximately 140,000 tpa of spodumene concentrate at 6.0% Li₂O, with flexibility down to 5.0% Li₂O. Plant availability is modelled at 86%, lithium recovery at 88%, and full production is expected to be reached over a three-year ramp-up period.
By-products include approximately 54,000 tpa of anhydrous sodium sulphate and approximately 130,000 tpa of alumina silicate (a cement additive), both of which are included in the financial model and contribute to overall project margins.

Next steps toward a Definitive Feasibility Study
Following completion of the PFS, the company has outlined the following pathway toward DFS:
- Commence Definitive Feasibility Study and detailed engineering activities
- Secure the proposed refinery site via a long-term lease with the Port of Brownsville (a two-year option over approximately 35 acres has been formally requested)
- Advance permitting, environmental, and site investigation programmes, with the Air New Source Review (NSR) permit anticipated to take approximately 12–18 months and overall environmental approvals estimated at 15–24 months, subject to detailed engineering and environmental studies
- Finalise long-term spodumene supply arrangements for the remaining approximately 40% of feedstock requirements
- Progress strategic financing, including the potential offer of up to a 49% equity interest in the project to strategic investors, with the target group expected to comprise spodumene producers or companies holding secured offtake seeking North American downstream conversion capacity
- Continue engagement with U.S. federal, Texas state, and local government agencies regarding potential grants and incentives
The financing strategy explicitly targets spodumene producers as equity partners, which the company notes has the potential to establish a more vertically integrated lithium supply chain while reducing LU7’s funding requirement. The study notes that funding of approximately US$620–650 million will likely be required to achieve the range of outcomes indicated, and investors are cautioned that there is no certainty Lithium Universe will be able to raise that amount when needed.
