The delivery fulfills LibertyStream’s previously announced first U.S. order and marks the Company’s first delivery from the Select site. The lithium carbonate was produced to the customer’s required technical specifications and delivered as part of LibertyStream’s broader customer qualification and commercial sales process.

With this delivery, LibertyStream has moved its Texas operations from site deployment and on-site production into customer delivery — an important step in derisking the Company’s plan to replicate its lithium extraction and refining model across high-volume U.S. oilfield basins, including the Permian and Bakken. “ We are proud of the pace of lithium carbonate production at Select’s site,” said Alex Wylie, President & CEO of LibertyStream. “Delivery of our first tonne of lithium carbonate achieving the required technical specifications, is another successful significant milestone by the entire LibertyStream team. We continue to make lithium carbonate for delivery to a number of battery grade and technical grade customers. With production now underway, we are positioned to reach an annualized production capability of up to 1,000 tonnes of lithium carbonate by the end of 2026.” Lithium Carbonate Operating Facility LibertyStream completed installation and construction of its Lithium Carbonate Operating Facility ahead of schedule in March 2026 and has commenced production from the Refining Unit.

The Refining Unit is engineered to produce both battery-grade and technical-grade lithium carbonate. The current configuration at Select’s site incorporates key learnings from the Company’s prior field operations and is designed to improve operating consistency as LibertyStream builds production history in the field. The first tonne delivery marks an important milestone as LibertyStream advances from site integration and production into customer qualification, product sales and planned scale-up.

LibertyStream expects the Select site to remain a core operating and validation platform as the Company expands customer deliveries and begins site preparation for the construction of its first Texas facility capable of annualized production of up to 1,000 tonnes of lithium carbonate by the end of 2026.
