US$100 Million Framework Deal Targets Breakthrough in Lithium Triangle Development
As global demand for battery-grade lithium continues to surge, developers are under increasing pressure to secure scalable, cost-efficient extraction methods while minimizing dilution. Direct Lithium Extraction (DLE) technology is rapidly gaining traction as a faster, more environmentally adaptable alternative to traditional evaporation ponds, and companies that can lock in both funding and proven technical partners are positioning themselves ahead of the next supply wave.
Shares of Argentina Lithium & Energy Corp. (TSX-V: LIT) (OTCQB: LILIF) are moving higher Tuesday after the company announced a non-binding Heads of Terms and Framework Agreement with Xi’an Lanshen New Material Technology Co., Ltd., outlining a potential US$100 million staged investment to advance its Rincon West Lithium Brine Project in Salta Province, Argentina.
The agreement establishes a structured three-stage development pathway, allowing Lanshen to earn up to a 30% equity interest in Argentina Lithium’s Argentine subsidiary through milestone-based contributions. The collaboration is designed to de-risk the project while progressing it toward commercial production using Lanshen’s DLE technology and engineering expertise.
Stage 1 will focus on pilot-scale DLE testing, process validation, and engineering work required to support a Pre-Feasibility Study, including flowsheet development and cost modeling. Stage 2 advances the project through Definitive Feasibility Study-level engineering, environmental and permitting support, and integration into NI 43-101 compliant technical studies.
The bulk of the proposed investment is tied to Stage 3, which contemplates approximately US$95.9 million in contributions toward the construction and commissioning of a commercial-scale lithium processing facility. The planned operation is designed to produce 5,000 tonnes per year of battery-grade lithium carbonate, with Lanshen providing a turnkey solution that includes engineering, equipment fabrication, logistics, installation support, commissioning, and operator training.
Rincon West hosts a recently defined NI 43-101 Mineral Resource Estimate of 238,000 tonnes of lithium carbonate equivalent in the Measured and Indicated category, along with an additional 64,000 tonnes in the Inferred category. The project is strategically located adjacent to Rio Tinto’s Rincon asset, placing it within one of the most active regions of South America’s Lithium Triangle.
The Framework Agreement builds on a prior Memorandum of Understanding signed in December 2025 and sets the stage for definitive agreements, which remain subject to due diligence, regulatory approvals, and standard closing conditions. Stellantis N.V., which holds a 19.9% interest in the Argentine subsidiary along with long-term offtake rights, is expected to remain part of the partnership structure moving forward.
Management highlighted that structuring the deal around staged contributions tied to development milestones provides a pathway to advance Rincon West while managing capital risk and limiting dilution.
Shares of LIT are ahead 8.0% to C$0.135 in Tuesday morning trading, while shares of LILIF have gained 8.8% to $0.099.
