LibertyStream Produces First Lithium Carbonate from Automated Refining Unit in Texas Permian Basin, Demonstrating End-to-End Field-Scale Production

LibertyStream Infrastructure Partners Inc.

• LibertyStream’s field-deployed Refining Unit is an automated continuous-flow system capable of producing up to 10 tonnes per annum of technical-grade and battery-grade lithium for U.S. customers.
• LibertyStream has secured approximately $4.0 million in gross proceeds post-September 30 quarter end through a combination of non-dilutive grant funding and option and warrant exercises, with participation from the Company’s largest institutional shareholder.

LibertyStream Infrastructure Partners Inc. (TSXV: LIB | OTCQB: VLTLF | FSE: I2D) (“LibertyStream” or the “Company”) is pleased to announce the commencement of lithium carbonate production from its automated continuous-flow refining unit (the “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,” said Alex Wylie, President & CEO of LibertyStream. “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.”

He emphasized the broader implications of this achievement: “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.”

LibertyStream Automated Continuous Flow Refining Unit

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 over 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 Near-Term Strategy

LibertyStream’s near-term focus is to produce consistent lithium carbonate that meets the technical specifications required by future customers for long-term offtake agreements.

To that end, the Company intends to:

1. Produce lithium carbonate batches for third-party laboratory testing and validation;
2. Confirm that the Refining Unit is delivering consistent product that meets customer technical specifications; and
3. Send bulk shipments, accompanied by certificates of analysis (COAs), for customer testing and qualification.

Following successful customer qualification, LibertyStream intends to initiate offtake discussions with prospective partners. The Company’s strategy is to secure agreements that will support the scale-up of lithium carbonate operations in 2026, with the goal of supplying commercial volumes to customers by 2027.

In the interim, LibertyStream intends to sell all lithium carbonate produced - outside of customer sampling - into the spot market in 2026 from its Refining Unit at its Texas field operations.

Approximately $4.0 Million from Recent Grant Funding and Option/Warrant Exercises

In recent weeks, LibertyStream has fortified its financial position through the exercise of outstanding share purchase warrants and stock options, including by the Company’s largest institutional shareholder, together with the receipt of previously announced non-dilutive grant funding. In total, these activities have resulted in aggregate gross proceeds of approximately $4.0 million (combined Canadian and U.S. dollars). These funds will directly support the Company’s strategic initiatives in Texas and North Dakota, with a primary focus on advancing its transition to commercial-scale lithium carbonate production.
