ENAMI, a Chilean lithium company, says that a joint venture with Rio Tinto will begin production in 2032.

Ivan Mlynarz, the company's chief, said that ENAMI, Chile's state-owned mining firm, aims to start production of its new Rio Tinto Lithium partnership at Altoandinos in 2032, with 35,000 metric tonnes per year. Production will then increase over three years, to 75,000 tons.

Rio Tinto will play a key role in the lithium industry of Chile with the Altoandinos and Maricunga projects, which it spearheaded this week alongside the state-run copper manufacturer Codelco.

Rio Tinto is committing $425 million initially to the project. ENAMI estimates that a total of $3 billion will be required.

Estimated previously

Altoandinos' project capacity was initially estimated at 60,000 tons per year. However, new studies revealed that there were more resources available than anticipated, especially on the La Isla flat of salt.

Mlynarz stated that ENAMI intends to begin the project with direct lithium extraction, a method that is yet to be tested in Chile and that Rio Tinto has been testing at its Rincon Project in Argentina.

ENAMI is testing DLE solutions from various companies. Mlynarz says that early results for Rio Tinto’s technology are promising and pave the way for the potential use of this technology on the project.

Mlynarz stated that the results with Rio Tinto were encouraging, and the operator was able to use its own technology.

He said that the partnership needs approval from international regulatory bodies, but in the interim, ENAMI will continue exploration studies in the hopes that Rio Tinto takes the lead in 2026.

Mlynarz stated that both ENAMI Rio Tinto understand the importance of timing.
