LIBERTYSTREAM ENTERS FINAL INSTALLATION AND COMMISSIONING PREP IN TEXAS, POSITIONING FOR Q4 2025 BULK LITHIUM CARBONATE PRODUCTION

Libertystream Infrastructure Partners Inc. has commenced site preparation for its coming lithium carbonate refining unit. This achievement reflects nine months of preparation for on-site operations, positioning the company to enter the final stage of derisking: converting lithium chloride eluate into commercial-grade lithium carbonate.

"We are very pleased that site preparation is under way for our lithium carbonate refining unit," said Alex Wylie, president and chief executive officer of Libertystream. "We have spent the past nine months preparing for on-site 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 on site, 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 and 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 -- on-site installation and tie-ins;
• Early November, 2025 -- initial runs and quality assurance validation;
• Second half of Q4 2025 -- start of lithium carbonate production.

The company also announces that it is granting two million options under its omnibus equity incentive plan to certain consultants. The options vest quarterly over a 12-month period commencing Oct. 7, 2025, and are exercisable at 24.5 cents per share for five years from the date of grant, expiring on Oct. 7, 2030.
