Lilac Solutions has taken a major step toward commercial development of its Great Salt Lake lithium project in Utah after signing a binding 10-year offtake agreement with Traxys North America for future battery-grade lithium carbonate production. Under the agreement, Traxys will purchase 50,000 tonnes of lithium carbonate over the contract period, representing 100% of the planned Phase 1 production capacity from Lilac’s facility.
The first development phase is designed to produce approximately 5,000 tonnes per year of battery-grade lithium carbonate, creating a defined commercial pathway for the project as it advances toward construction and financing decisions.
Offtake Agreement Provides Critical Commercial Certainty
The agreement highlights the growing importance of lithium offtake contracts as a key milestone for emerging battery materials projects. While direct lithium extraction (DLE) technology has gained significant attention for its potential to unlock unconventional lithium resources, investors and lenders increasingly require evidence that projects can secure customers and generate predictable revenue streams before committing major capital.
The Lilac-Traxys agreement provides that commercial validation by establishing a long-term sales channel for the project’s planned production. The contract includes a take-or-pay structure linked to market-based pricing indices, giving the project greater visibility over future revenues and strengthening its position in discussions with potential financiers. For lithium developers, securing an offtake partner can be the difference between a promising resource concept and a project capable of advancing toward construction.
DLE Technology Performance Remains Central to Project Economics
Although the offtake agreement represents a major milestone, the technical performance of Lilac’s extraction technology remains a critical factor in determining the project’s success. The company has reported that its Gen 5 ion exchange technology achieved a lithium recovery rate of 87% during pilot plant testing completed in 2025.
The tests were conducted using ultra-low-grade brine containing 69 milligrams per litre of lithium, highlighting the technical challenge of extracting lithium from Great Salt Lake resources.
Unlike traditional lithium operations based on higher-grade deposits, the economics of low-concentration brine projects depend heavily on technology efficiency, operating costs and the ability to scale laboratory and pilot results into reliable commercial production. Key factors will include reagent consumption, water management, environmental compliance, permitting progress and maintaining consistent performance during full-scale operations.
Traxys Adds Market Access and Supply Chain Expertise
The involvement of Traxys North America provides more than a customer relationship. As a global commodities trader, Traxys brings experience in marketing, logistics, financing structures and international supply chains, helping connect lithium production with end users across the battery and industrial markets.
For developing lithium projects, merchant offtake partners can play an important role by providing access to customers, pricing mechanisms and established distribution networks. The agreement strengthens Lilac’s commercial position while helping integrate Great Salt Lake into the broader North American lithium supply chain.
Great Salt Lake Moves Beyond a Technology Demonstration Project
The long-term offtake agreement does not eliminate all project risks. Challenges remain around technology scale-up, permitting, environmental management and construction execution. It significantly changes the project’s development profile.
Great Salt Lake is no longer only a demonstration of direct lithium extraction technology. With a committed buyer for its entire planned Phase 1 output, the project now has a clearer commercial framework and a stronger foundation for future investment decisions. As demand for lithium continues to expand alongside electric vehicles, energy storage and clean technology markets, projects that can combine innovative extraction methods with secured customers are likely to attract increasing attention from investors and strategic partners.
