LibertyStream Strengthens Lithium Platform with Faster Cycle Times, Improved Reliability, and On-Site Lithium Carbonate Production

• LibertyStream’s Gen 6 direct lithium extraction platform incorporates 21 months of field operations, more than 400,000 barrels of processed brine, and over 2,500 operating tests into an improved operating configuration designed to enhance reliability, throughput stability, and lithium carbonate production quality.
• The Gen 6 platform reduces cycle time to approximately 20 minutes, compared with approximately 60 minutes under the Gen 5 configuration, supporting lower reagent consumption, energy use, and labor cost per tonne of lithium carbonate equivalent.
• The Gen 6 system was installed at Select Water Solutions’ facility in Howard County, Texas in March 2026, where lithium carbonate production is underway, including output supporting technical- and battery-grade applications.
• The system establishes the operating template for LibertyStream’s integrated extraction-and-refining system, designed to process up to 120,000 barrels of oilfield brine per day and produce up to 1,000 tonnes per annum of lithium carbonate.

LibertyStream Infrastructure Partners Inc. (TSXV: LIB | OTCQB: VLTLF | FSE: I2D) (“LibertyStream” or the “Company”) announces that it has strengthened its Gen 6 lithium extraction platform by applying 21 months of field operations, pilot programs, and Gen 5 operating data to an improved operating configuration. The Gen 6 platform converts field learnings into faster cycle times, reduced operating variability, improved reliability, and on-site lithium carbonate production, including output supporting technical- and battery-grade applications.

“Gen 6 reflects the operating discipline and field experience LibertyStream has built over the past 21 months,” commented Alex Wylie, President & CEO of LibertyStream. “We have processed more than 400,000 barrels of brine, completed over 2,500 operating tests, and applied that data to improve recovery speed, throughput stability, reliability, and lithium carbonate quality. With the system installed at Select and production underway on site, LibertyStream is better positioned to advance customer qualification, scaled deployment, and future replication across high-volume U.S. brine resources.”

Field Validation Drives Next Generation Platform Improvements

LibertyStream has successfully extracted lithium from oilfield brine for the past 21 months at its Texas field operations, establishing a field-tested operating base for scaled deployment. During the initial six months of field activity, the Company scaled its system three times, culminating in the commissioning of its Gen 5 operating platform in February 2025. The Gen 5 system was designed to process up to 10,000 barrels of oilfield brine per day and has since processed more than 400,000 barrels of brine across over 2,500 operating tests.

This operating history directly informed the Gen 6 configuration. Implemented in the second half of 2025, Gen 6 uses a continuous-flow model that integrates DLE, rinse, and acid-recovery operations. This configuration reduces mechanical complexity, minimizes batch-related variability, and streamlines the extraction sequence. Over the past eight months, LibertyStream has completed more than 200 Gen 6 field trials, demonstrating a step-change improvement in performance relative to Gen 5.

Following this field validation program, LibertyStream installed the Gen 6 system at Select Water Solutions’ facility in Howard County, Texas in March 2026. The system is producing lithium carbonate on site, including output supporting technical- and battery-grade applications, and establishes the operating template for LibertyStream’s integrated extraction-and-refining system designed to produce up to 1,000 tonnes per annum of lithium carbonate.

The Gen 6 configuration incorporates a total operating performance approach, including equipment life, reliability, process automation, reagent consumption, and operating consistency. The platform reduces cycle time, supports lower reagent consumption, and strengthens the stability of lithium carbonate production. Its continuous-flow design and improved asset protection support uptime, maintenance efficiency, and more reliable operation in West Texas field conditions.

The refined design improves operational assurance and aligns the system with the requirements of downstream customers, strategic partners, and financing stakeholders. It also strengthens LibertyStream’s modular, infrastructure-integrated production model as the Company advances deployment across high-volume U.S. brine resources.

Gen 6 Platform Improvements vs. Gen 5

Together, these improvements support commissioning readiness, limit operational variability, and strengthen the facility’s ability to meet stringent product-quality requirements. By incorporating these reliability and performance features into the initial build, LibertyStream is positioning the platform for a more stable ramp toward steady-state production and future deployments.
