LONDON, May 22, 2025--(BUSINESS WIRE)--Rio Tinto has today been confirmed as the preferred partner for the Salares Altoandinos lithium project in the Atacama region of Chile by Empresa Nacional de Minería (ENAMI), a state-owned Chilean mining company.

Rio Tinto Chief Executive Jakob Stausholm said: "We are honoured to have been selected by ENAMI as the preferred partner for the Salares Altoandinos project, which has the potential to be a world-class lithium development.

"We welcome the opportunity to develop our partnership with ENAMI, building on our interests in Nuevo Cobre and Salar de Maricunga, and to support Chile’s position as one of the world’s leading producers of minerals critical to the energy transition."

Under the terms of the proposal, Rio Tinto would acquire an initial 51% stake in the project with ENAMI holding the remaining 49%. The transaction remains subject to the signature of binding agreements, receipt of all regulatory approvals and the satisfaction of other customary closing conditions.

Building a world-class lithium business

Rio Tinto is advancing its world-class lithium business and establishing itself as a global leader in the supply of energy transition commodities.

With a strategic pipeline of tier 1 lithium assets and options, including those from the recent acquisition of Arcadium Lithium, Rio Tinto now holds one of the world’s largest lithium portfolios.

An expanding South American pipeline complements the projects in Canada and Serbia. This includes (see full detail in the table below):

Chile

  • Altoandinos – a new partnership with ENAMI

  • Maricunga – a new partnership with Codelco

Argentina

  • Rincon, Olaroz, Fenix, Sal de Vida and Cauchari

Long-term outlook for lithium1

Rio Tinto has been consistent in its belief in the long-term outlook for lithium, with an expected market deficit emerging from the end of this decade. It expects a more than 10% compound annual growth rate for demand through to 2040.

With spot lithium prices down more than 80% versus peak prices, these additions to the portfolio come at a time with substantial long-term market and portfolio upside, underpinned by an appealing market structure and established jurisdictions.
