LibertyStream Infrastructure Partners Inc. (TSXV: LIB | OTCQB: VLTLF | FSE: I2D) (“LibertyStream” or the “Company”) is pleased to announce that site preparation has commenced for its upcoming Lithium Carbonate Refining Unit (the” Refining Unit”). This achievement reflects nine months of preparation for onsite operations, positioning the Company to enter the final stage of de-risking: converting lithium chloride eluate into commercial-grade lithium carbonate.

“We are very pleased that site preparation is underway for our lithium carbonate Refining Unit,” said Alex Wylie, President & CEO of LibertyStream. “We have spent the past nine months preparing for onsite lithium carbonate refining. As we enter the fourth quarter, the commissioning of our refining unit and subsequent conversion of stockpiled lithium chloride eluate into commercial-grade lithium carbonate marks the final critical step toward launching full-scale operations in 2026.”

Concrete Pads Layout for Lithium Carbonate Refining Unit

The Refining Unit will be strategically located onsite, adjacent to the direct lithium extraction field unit, to optimize operational efficiency. The three dedicated pads in the site layout represent the three phases of the refining train:

• Softening & Polishing — delivers a clear, specification-controlled lithium-chloride feed that is crystallization-ready.
• Technical-Grade Lithium Carbonate — produces consistent Lithium Carbonate (Li₂CO₃) for industrial applications with stable yield and product uniformity.
• Battery-Grade Finishing — upgrades to high-purity Li₂CO₃ meeting battery-grade specifications with tight impurity control.

Project Timeline

• Early October 2025: Concrete and secondary containment
• Late October 2025: Onsite installation and tie-ins
• Early November 2025: Initial runs and QA validation
• 2^nd Half Q4 2025: Start of lithium carbonate production

The Company also announces that it is granting 2,000,000 options (“Options”) under its omnibus equity incentive plan to certain consultants. The Options vest quarterly over a twelve-month period commencing October 7, 2025 and are exercisable at $0.245 per Share for five years from the date of grant, expiring on October 7, 2030.
