Lithium Americas' Thacker Pass Project Costs Soar 31% to $3.83 Billion Amidst Rising Expenses

Lithium Americas announced on Wednesday a significant increase in the estimated cost for its primary Thacker Pass lithium project, now projected at $3.83 billion. This represents a 31% rise from previous estimates, attributed by the company to escalating labor, construction, and logistics expenses. The revised budget incorporates an additional $895 million in capital costs, increasing the funding requirements for the Nevada-based project by approximately $995 million. Lithium Americas indicated that these additional funds are expected to be sourced from company contributions and existing loan reserves from the US Energy Department. Following this announcement, the company's shares experienced a decline of over 8% during Wednesday's trading session.

Jonathan Evans, CEO of Lithium Americas, stated that Phase 1 construction for the project is slated to commence in late 2027, with significant activity continuing throughout 2028. "Despite external and internal factors impacting the project’s capital cost estimate, the anticipated capital cost for Thacker Pass is expected to remain funded as we continue to deliver on our execution plan and bring the project safely into production," Mr. Evans commented in a statement. The company also noted that labor installation rates for piping, steel, and equipment contributed $245 million to the cost increase, while tariffs and logistics added another $100 million. Global and national shipping conditions, coupled with reduced availability of US fabrication, have notably impacted logistics costs, exacerbated by rising fuel prices.

The Thacker Pass mine, a joint venture with General Motors, is recognized as one of the largest known lithium deposits in the United States. At full capacity, Lithium Americas anticipates the project will yield 40,000 tonnes per year of battery-quality lithium carbonate, a crucial component for electric vehicles. Global demand for rechargeable chemical batteries is projected to more than quadruple by 2030 compared to 2023 levels, according to the Centre for Strategic and International Studies. Currently, the Silver Peak Lithium Mine is the sole active, commercial-producing lithium mine in the US, accounting for about 1% of global production.

"Thacker Pass is essential to America's economic and national security, and we are committed to delivering it," Mr. Evans emphasized. However, the escalating costs highlight the difficulties in establishing a domestic supply chain for lithium. The majority of global lithium mining is concentrated in Australia, Chile, and China, which collectively account for 90% of production, with China processing approximately 65% of global lithium, making it the dominant player. In September 2025, the Energy Department acquired a 5% equity stake and an additional 5% ownership through warrants in the Thacker Pass joint venture, as part of a restructuring of a multibillion-dollar loan aimed at supporting the launch of the US's only domestic source of lithium carbonate.

Mr. Evans previously mentioned in March at Future Initiative Investment's Miami summit that Lithium Americas is fortunate to have the US government as a significant backstop, acknowledging that the US has been lagging in the critical minerals race. The administration under President Donald Trump has previously invested in other mining companies, including MP Materials, USA Rare Earth, Vulcan Elements, and Trilogy Metals, as part of its strategy to achieve self-reliance in critical minerals. The administration is also supporting a project by Korea Zinc in Tennessee and seeking to diversify the critical minerals supply chain through diplomatic efforts with international partners like the Quad and G7. A framework for cooperation on securing critical minerals was announced last year between the US and Saudi Arabia, aiming to foster bilateral investment in minerals. Additionally, the Defence Department is financing a 49% equity stake in a new rare earth minerals refinery in Saudi Arabia through a joint venture with Maaden, in partnership with MP Materials.
