Lithium Americas is facing a potential $80 million to $120 million increase in construction costs at its Thacker Pass lithium project in Nevada, driven by US steel tariffs, inflation linked to Middle East tensions, and shipping disruptions around the Strait of Hormuz. The escalation highlights growing cost pressure across the lithium mining and battery supply chain as global trade and energy markets remain volatile.
The company confirmed the impact alongside its first-quarter results, as construction accelerates toward a planned 2027 startup. Thacker Pass is one of the most strategically important lithium projects in the United States, designed to strengthen domestic lithium carbonate supply for electric vehicle (EV) battery production.
Tariffs and Geopolitical Disruptions Raise Lithium Project Costs
Lithium Americas said US tariffs on steel imports are a key driver of rising capital costs, alongside inflationary pressures linked to the conflict in Iran and broader Middle East instability. Shipping disruptions through the Strait of Hormuz have further increased logistics and procurement uncertainty.
The company noted that its original $2.93 billion Phase 1 capital estimate did not include tariffs, higher fuel costs, or inflation risks. As a result, it has launched a revised capital estimate to incorporate updated assumptions on materials, labor, and logistics.
Despite cost inflation, more than 75% of structural steel sourced from the United Arab Emirates has already been delivered or is in transit. However, rerouting shipments through Saudi Arabia’s Port of Jeddah has added complexity to supply chain execution.
Construction Advances Amid Rising Supply Chain Pressure
Construction at Thacker Pass continues to scale up, with more than 1,300 workers currently on site and peak construction expected to exceed 2,000 workers. The project is moving toward mechanical completion by late 2027, with procurement already more than 70% complete.
Lithium Americas has also secured and delivered major long-lead equipment, including transformers, reactors, and steam turbine components, which are critical for processing lithium carbonate.
As of March 31, the company had capitalized approximately $1.3 billion in construction and project-related costs. It also reported a strong liquidity position, supported by cash holdings and a $432 million advance from a US Department of Energy loan facility.
Strategic Importance of US Lithium Supply Chain
Once operational, Thacker Pass is expected to produce around 40,000 tonnes of lithium carbonate annually, supporting battery production for roughly 800,000 electric vehicles. This would make it one of the largest lithium operations in North America and significantly larger than existing US lithium brine production.
The project has attracted strategic backing from General Motors, Orion Resource Partners, and the US government, reflecting its importance to domestic critical mineral supply chains and energy security policy.
However, rising construction costs underscore broader challenges facing Western countries attempting to localize battery material production. Inflation in steel, energy, and logistics is becoming a structural risk for large-scale lithium and EV supply chain investments.

SuperMetalPrice Commentary:
The Thacker Pass cost escalation reflects a broader structural reality in critical mineral development: lithium supply expansion is increasingly constrained not by resources, but by industrial inputs and geopolitical friction. Steel tariffs and logistics disruptions are now directly influencing battery metal project economics.
As a result, cost inflation risks could slow the pace of Western lithium supply expansion, reinforcing medium-term support for lithium carbonate prices as demand from EV and energy storage continues to grow.
