LibertyStream has commenced lithium carbonate production from its automated continuous-flow refining unit at field operations in the Permian Basin, Texas. This milestone marks LibertyStream’s first field production of lithium carbonate from oilfield brine, demonstrating a fully integrated, end-to-end pathway from produced water to saleable lithium carbonate at the disposal well site.

By coupling the refining unit with LibertyStream’s proprietary direct lithium extraction (DLE) technology on existing oilfield infrastructure, the company has de-risked a scalable template it aims to replicate across high-volume U.S. basins such as the Permian and Bakken.

“Our team at LibertyStream has achieved a rare commercial milestone and we are firmly on the path toward expansion across critical U.S. oilfields in the Permian Basin in Texas and the Bakken in North Dakota. Our automated refining unit in the Permian Basin has now demonstrated that our technology and process — converting oilfield brine into high-purity lithium — has exceeded expectations,” said Alex Wylie, president and CEO of LibertyStream.

“This breakthrough positions LibertyStream to scale responsibly, supply critical lithium carbonate for domestic industrial customers and defence contractors, and create meaningful shareholder value as we replicate modules and secure long-term commercial contracts,” added Wylie.

Over the past 16 months, LibertyStream’s Texas field operations have scaled up successfully through the commissioning of its proprietary Generation 5 Direct Lithium Extraction (DLE) unit. This system is capable of processing up to 10,000 barrels of oilfield brine per day into a lithium chloride eluate. Since February 2025, LibertyStream has processed more than 350,000 barrels of brine and conducted more than 2,500 real-time validation tests, underscoring the robustness and reliability of its technology.

The next critical stage for LibertyStream’s operations was the conversion of lithium chloride eluate into a lithium carbonate product meeting the stringent technical specifications required by industrial, electric vehicle, and military customers. To achieve this, the company has installed and commissioned an automated continuous-flow lithium carbonate refining unit at its Texas field site, designed to deliver consistent and repeatable production for American customers.

The Refining Unit converts lithium chloride eluate from LibertyStream’s proprietary DLE system into technical grade or battery grade lithium carbonate. With a capacity of up to 10 tonnes per annum and a modular, scalable design, the system ensures seamless integration with LibertyStream’s DLE platform.

LibertyStream is a lithium development and technology company aiming to be one of North America’s first commercial producers of lithium carbonate from oilfield brine. Their strategy is to generate value for shareholders by leveraging management’s hydrocarbon experience to deploy its proprietary DLE technology directly into existing oil and gas infrastructure, thereby reducing capital costs, lowering risks and supporting the world’s clean energy transition. They are committed to operating efficiently and with transparency across all areas of the business staying sharply focused on creating long-term, sustainable shareholder value.
