Codelco’s Maricunga lithium delay to 2034: schedule and permitting lessons for mine planners

30 Second Briefing
Codelco has pushed first production at the Maricunga lithium project, which hosts the world’s second-largest known lithium concentration, from 2030 to 2034, citing an eight-year remaining timeline. The project will be advanced under a 2025 partnership with Rio Tinto and an updated Special Lithium Operating Contract (CEOL), aligning it with Chile’s National Lithium Strategy and tighter state oversight. The four-year delay signals prolonged permitting, consultation and environmental approval cycles for new brine developments in Chile’s high-altitude salars.
Technical Brief
- Capital intensity of Codelco’s wider growth pipeline is driving reliance on international partners for project funding.
Our Take
The delay at Maricunga comes as Codelco’s new chairman Bernardo Fontaine is already steering the company to prioritise profitability over volume, suggesting lithium growth in Chile may be paced more conservatively than earlier government targets implied.
Our database shows most recent Chile coverage around Codelco has focused on copper optimisation, such as the joint mine plan with Anglo American at Los Bronces–Andina, so pushing Maricunga to 2034 likely reflects capital and management bandwidth being reserved for near-term copper returns rather than greenfield battery metals.
With Rio Tinto involved at Maricunga and Albemarle and SQM already entrenched in Chilean lithium, a 2034 start shifts competitive dynamics: incumbents are likely to retain pricing and offtake leverage longer, while Codelco’s state-backed entry into battery metals is pushed into a later demand cycle.
