Lithium Americas raises Thacker Pass total cost estimate to $3.83 billion, targeting late 2027 completion

Lithium Americas Corp. has revised the total capital cost estimate for its Thacker Pass lithium project in Humboldt County, Nevada, up to $3.83 billion, an increase from the previous figure of $2.93 billion outlined in its December 2024 technical report. The company also lifted its 2026 capital expenditure guidance as construction costs climb on the Phase 1 build.

Mechanical completion of Thacker Pass Phase 1 is now targeted for late 2027, with a production ramp-up expected through 2028. Once at full capacity, the project is designed to produce 40,000 tonnes per year of battery-quality lithium carbonate, positioning it as one of the largest domestically sourced lithium supplies in the United States.

Lithium Americas trades on both the TSX and NYSE under the ticker LAC. The updated cost and schedule figures represent a significant escalation from prior guidance and come as the company has already capitalized more than $1.3 billion in construction and project-related costs to date.
