Cauchari-Olaroz Surges: 97% Capacity, Prices Double

Cauchari-Olaroz produced 9,660 tonnes of lithium carbonate at 97% utilization, with realized prices surging 108% year-over-year to $16,818/tonne

At the edge of the Puna plateau in Argentina's Jujuy province, one of the world's largest lithium brine operations is running nearly flat out. Cauchari-Olaroz, majority-owned by Lithium Argentina alongside partners Ganfeng Lithium and Minera Exar, produced 9,660 tonnes of lithium carbonate in the first quarter of 2026, using 97% of its available capacity. The numbers are tidy. The timing is fortunate.

Prices have recovered sharply. Realized prices reached $16,818 per tonne, up 108% from a year earlier, when the market was still digesting a glut that had punished producers for most of 2024. Cash operating costs held at $5,391 per tonne. The gap between those two figures, more than $11,000 per tonne, is the kind of margin that quiets anxious shareholders and emboldens expansion talk.

Full-year guidance of 35,000 to 40,000 tonnes remains unchanged. Running at near-maximum capacity so early in the year makes that target look achievable without the operational strain that has haunted other large-scale brine projects. Chief Executive Sam Pigott offered a measured assessment. "Strong production through the fourth quarter, together with continued cost reductions, highlights the increasing operational maturity of the business and positions us well for the next stage of growth," he said.

Yet the more telling story is structural. South American brine producers have long promised scale; Cauchari-Olaroz is now delivering it. For buyers seeking long-term supply contracts, sustained high utilization from a project of this size changes the calculus. Supply security, not just price, is driving procurement decisions across the battery supply chain.

Two risks linger. Lithium prices, though recovering, remain volatile, and any renewed softness would compress those enviable margins quickly. Brine operations also depend on stable regulatory and water-use conditions in a region where both have occasionally proved fragile. For now, the numbers look strong. Whether they reflect a durable shift or a well-timed upswing will take several more quarters to determine.
