Rio Tinto Opens $1.4 Billion Lithium Projects in Catamarca

Rio Tinto has inaugurated the Fenix 1B expansion and the new Sal de Vida operation in Catamarca Province, Argentina, following a combined investment of around $1.4 billion. Both brine-based lithium projects achieved first production in the second quarter, ahead of plan, and are now ramping up toward a combined 25,000 metric tons of annual lithium carbonate equivalent capacity.

Fenix has operated since 1997 as Argentina's first commercial lithium operation, and the 1B expansion adds 10,000 metric tons of annual LCE capacity, lifting the site's target to approximately 40,000 metric tons. Sal de Vida, a new lithium carbonate operation located roughly twenty kilometers northeast of Fenix, carries a target of 15,000 metric tons per year. The inauguration was hosted by Rio Tinto chief executive Simon Trott and attended by Argentine President Javier Milei and Catamarca Governor Raul Jalil. Trott framed the two projects as proof of delivery capability on the path to the company's global target of 200,000 metric tons of annual LCE production capacity by 2028, crediting the Argentine workforce and the capabilities of local suppliers. Milei described the expansion as a historic milestone made possible by renewed investment incentives in the country's mining sector.

For pump and valve suppliers, brine lithium is quietly becoming one of the more demanding growth markets in fluid handling. Salar brines combine high chloride content with variable salinity and temperature, so materials selection—elastomers, duplex alloys, rubber-lined wetted parts—decides whether installed pumps survive their warranty period, and any supplier quoting into Fenix or Sal de Vida should expect corrosion and seal life to dominate the technical evaluation. The ramp-up profile also matters commercially: first production is behind these projects but full capacity is not, which means phased equipment orders, flow-loop modifications and additional injection or extraction duty as wells are added, rather than a single lump procurement. Rio Tinto's stated path to 200,000 metric tons of LCE capacity by 2028 signals that Catamarca will keep generating capex well beyond this inauguration, and the chief executive's explicit recognition of Argentine suppliers suggests localization expectations will shape bid lists on follow-on packages. Procurement teams at EPCs and equipment distributors should treat the Argentinian brine corridor as a multi-year pipeline of rotating equipment, valve and pipeline orders, and position spare parts and field service coverage accordingly, since utilization and availability of the brine pumping circuit will directly gate each project's path to nameplate capacity.
