The move seeks to combine two neighbouring projects operated by the companies in the Pastos Grandes basin, located in the Argentine’s side of South America’s lithium triangle, close to Lithium Americas’ Caucharí-Olaroz. This lithium brine project is expected to enter production in H1 2023.
“The significant synergies between our two projects and a better understanding of the basin will enable us to advance development planning and maximize our growth pipeline in Argentina,” chief executive officer Jonathan Evans said in the statement.
The deal, expected to close in the third quarter of 2023, comes as Lithium Americas goes through a business transformation that will see it separate its North American and Argentine businesses into two independent public companies.
The new Lithium Americas company, to be headed by Evans, will own the Thacker Pass lithium project in Nevada and investments in Green Technology Metals (ASX: GT1) and Ascend Elements.
The other new company, Lithium International, will focus on the Argentine assets, the company said in November. These projects include Caucharí-Olaroz and Pastos Grandes.
China-based Ganfeng Lithium, GFL International and their affiliates collectively own about 16% of Arena’s outstanding shares as well as warrants that if exercised would represent a further 6% stake.
Lithium Americas said Ganfeng has entered an agreement to dispose of all of its securities of Arena prior to the merger closing.
Prices have continued to climb this year, after an explosive rally in 2021, even as more supply of the battery metal has hit the market.
Benchmark Mineral Intelligence data shows spodumene prices up 257% this year, averaging some $5,900 a tonne for 6% concentrate Australian free on board price in November.
Australia, the world’s largest lithium exporter, is predicting a sharp fall of the metal’s prices in 2024.
