ARGENTINA LITHIUM ANNOUNCES MEMORANDUM OF UNDERSTANDING WITH XI'AN LANSHEN NEW MATERIAL TECHNOLOGY TO ADVANCE RINCON WEST LITHIUM PROJECT

Argentina Lithium & Energy Corp. has entered into a memorandum of understanding (MOU) with Xi'an Lanshen New Material Technology Co. Ltd., a globally recognized direct lithium extraction (DLE) technology leader. This strategic collaboration establishes the framework for Lanshen to deploy its proprietary DLE systems, pilot plant technology, advanced engineering solutions and project-development expertise to accelerate the advancement of Argentina Lithium's flagship Rincon West lithium brine project toward feasibility study completion and potential future commercial production.

Under the MOU, Argentina Lithium and Lanshen intend to jointly advance Rincon West through all stages of technical, environmental, regulatory and engineering development leading to a full feasibility-level evaluation of a 5,000-tonne-per-year battery-grade lithium carbonate plant, with future scalability to 15,000 to 20,000 tonnes annually. Lanshen is expected to provide its integrated DLE pilot platform, engineering packages, technical personnel, process design and equipment quotations required for feasibility-level engineering. Lanshen's contributions -- including technical services, specialized equipment, engineering studies and pilot plant design -- will qualify for equity participation in Argentina Lithium's wholly owned subsidiary, Argentina Litio y Energia S.A. (ALESA), through a progressive earn-in structure. The parties will subsequently negotiate a definitive collaboration agreement (DCA) that will formalize commercial arrangements including exclusivity for DLE technology, governance, long-term financing structures and IP licensing. The MOU is non-binding except for confidentiality and certain legal provisions, and will remain in place for 12 months while the parties progress due diligence and negotiate the DCA.

The collaboration marks a significant milestone following Argentina Lithium's recently announced National Instrument 43-101 mineral resource estimate at Rincon West. The project is strategically located adjacent to Rio Tinto's world-class Rincon operation in Salta province, placing it in one of the most competitive and technically attractive brine jurisdictions in the world. Argentina Lithium will continue to lead environmental permitting, community engagement, hydrogeological work, metallurgical programs, site logistics and integration of the DLE flowsheet into the overall engineering strategy for Rincon West. The combined strengths of both parties are expected to reduce development timelines, improve process efficiency and materially enhance the project's commercial pathway.

Nikolaos Cacos, chief executive officer of Argentina Lithium, stated: "This MOU with Lanshen represents a pivotal turning point for Argentina Lithium. By aligning ourselves with a global DLE technology leader capable of delivering pilot systems, engineering and commercial-scale solutions, we are dramatically strengthening the technical foundation and strategic positioning of Rincon West. The combined capabilities of both organizations will accelerate our development timeline, reduce technical risks and unlock the full long-term value of our lithium brine assets within the Lithium Triangle."

Zhijun Feng, president of Lanshen, commented: "We are very pleased to commence this collaboration with Argentina Lithium. Lanshen's DLE technology suite has been developed over more than a decade to deliver high lithium recovery, low impurity, environmentally efficient extraction solutions. Our team looks forward to bringing our engineering capabilities and industrial experience to the Rincon West project, supporting Argentina Lithium in advancing toward feasibility and, ultimately, commercial production."

Argentina Lithium's strategic framework is already strengthened by its relationship with Stellantis N.V., which holds a 19.9-per-cent interest in ALESA and long-term offtake rights of up to 15,000 tonnes per annum of LCE. With the addition of Lanshen as a specialized technical partner, Rincon West is being positioned as a next-generation lithium project aligned with the global shift toward cleaner, more efficient production technologies.
