Rio Tinto Lithium LTHMWI

Company Overview

Rio Tinto Lithium is the lithium-focused business activity within Rio Tinto Group, the global mining and metals company headquartered in London, United Kingdom, and Melbourne, Australia. The business operates within Rio Tinto’s broader critical minerals strategy and focuses on the exploration, development, and production of lithium materials used primarily in electric vehicle batteries, energy storage systems, and other electrification technologies. Rio Tinto participates in the mining industry, battery materials supply chain, and broader energy transition sector through its lithium investments and operating assets.

The company’s lithium strategy has evolved significantly since the early 2020s through acquisitions and project development initiatives. Key revenue and growth drivers include lithium brine and hard-rock development projects, particularly in Argentina and other resource-rich jurisdictions. Rio Tinto’s lithium platform expanded materially following the acquisition of Arcadium Lithium in 2025, adding a global portfolio of lithium extraction, processing, and marketing operations. Rio Tinto’s strategic advantages include its scale as a diversified miner, established global logistics and infrastructure capabilities, access to capital, and existing relationships with industrial and automotive customers seeking long-term battery materials supply.
