LIBERTYSTREAM REPORTS THREE MONTHS OF CONSISTENT BATTERY-GRADE LITHIUM CARBONATE PRODUCTION

Libertystream Infrastructure Partners Inc. has provided an operating update from Freedom Launchpad, its production, customer-qualification and training platform located at Select Water Solutions' site in Howard county, Texas.

Libertystream lithium carbonate assay results from Freedom Launchpad, April 23 through Aug. 14, 2026, showing the May 20 transition to battery-grade targeting and nine consecutive certificates of analysis above the 99.5 per cent battery-grade purity reference. Assays were reported by NSL Analytical Services.

Since the refining system was configured for battery-grade production on May 14, 2026, every full certificate of analysis issued through Aug. 14 has reported lithium carbonate purity at or above 99.7 per cent, exceeding the 99.5-per-cent minimum purity commonly specified for battery-grade lithium carbonate.

The three-month record demonstrates consistent lithium carbonate purity across repeated production campaigns.

Freedom Launchpad's fully automated Gen 6 direct lithium extraction system and integrated refining equipment remain in active operation. The platform has produced approximately three tonnes of lithium carbonate across three distinct product requirements: battery-grade, technical-grade and customer-specific material. This includes one tonne manufactured to a customer's required specification and delivered under Libertystream's initial industrial trial order.

"Everything starts with operations," said Alex Wylie, president and chief executive officer of Libertystream. "Three months of production at battery-grade purity demonstrates the repeatability of our process. Customer work spanning seven organizations and our first definitive offtake agreement reflect market interest in our product."

Production supporting multiple customer paths

Beginning in early July, 2026, lithium carbonate samples have been delivered to four customer organizations for evaluation. Libertystream has also produced material meeting specifications supplied by three additional prospective customers.

This customer work builds on Libertystream's first definitive lithium carbonate offtake agreement, which provides for 600 tonnes per year beginning in 2027 and establishes contracted demand for planned production from Freedom 1.

The company continues to produce material for customer evaluation, refine product specifications and advance multiple qualification and commercial discussions.

Operating today, advancing Freedom 1

Freedom Launchpad uses the core equipment types, automation and process architecture intended for commercial deployment at Freedom 1, Libertystream's planned 1,000-tonne-per-year lithium carbonate facility.

Each production campaign does more than produce lithium carbonate. It supplies customers with material to evaluate while generating operating data, training personnel and refining procedures.

Libertystream expects to provide further updates as production continues, customer evaluations advance and Freedom 1 development progresses.
