[Rio Tinto Proposes to Invest Approximately $425 Million in the Development of the Salares Altoandinos Lithium Project in Chile] Rio Tinto announced on May 22 that it has been confirmed by Chile's state-owned mining company, ENAMI, as the preferred partner for the Salares Altoandinos lithium project on the salt flats in northern Chile. According to the proposed terms, Rio Tinto will acquire an initial 51% stake in the project, with ENAMI holding the remaining shares. Both parties still need to sign a binding agreement, obtain all regulatory approvals, and meet other customary closing conditions. Rio Tinto stated that it will advance pre-feasibility and feasibility studies to ultimately make an investment decision. Rio Tinto will provide approximately $425 million in cash and non-cash contributions, including its direct lithium extraction (DLE) technology. The cash contributions will be disbursed in phases to fund the pre-feasibility study and further research.
