CleanTech Lithium Confirms Robust Laguna Verde Economics After Technical PFS Adjustment

The latest update is out from CleanTech Lithium PLC ( (GB:CTL) ).

CleanTech Lithium has issued a correction to technical data in its recent Pre-Feasibility Study for the Laguna Verde project, revising the lithium recovery rate assumption from 90.0% to 85.5% to align with the process plant recovery figure. The adjustment, which requires higher modelled brine feed rates and reflects updated well flow assumptions, does not change reported reserves, project economics or any other key outcomes of the study.

The Laguna Verde PFS confirms projected output of 15,000 tonnes per year of battery-grade lithium carbonate over a 25-year life, with a pre-tax NPV of US$1.37 billion, a pre-tax IRR of 24.2% and operating costs that place the project in the industry’s lowest cost quartile. Backed by a recently agreed long-term operating contract framework with the Chilean government, the study underpins CleanTech Lithium’s plan to secure a strategic partner, advance permitting and environmental assessments, and progress towards a Definitive Feasibility Study while capitalising on strong lithium demand and Chile’s competitive mining ecosystem.

The project configuration splits operations between a high-altitude Laguna Verde site for brine extraction, Direct Lithium Extraction processing and lithium chloride production, and a downstream lithium carbonate plant in the regional hub of Copiapó. This design reduces the environmental footprint at the salar, improves access to skilled labour and infrastructure, and provides optionality to scale processing capacity for potential future projects in the region.

Spark’s Take on CTL Stock

According to Spark, TipRanks’ AI Analyst, CTL is a Neutral.

The score is held down primarily by weak financial performance: the company is still pre-revenue with growing losses and ongoing negative operating and free cash flow, implying continued reliance on external funding despite only moderate leverage. This is partially offset by strong technical momentum, with the share price above all key moving averages and supportive MACD/RSI readings. Valuation remains constrained by the negative P/E and lack of dividend yield.
