LIBERTYSTREAM ACHIEVES CONSISTENT, SPEC-COMPLIANT LITHIUM CARBONATE PRODUCTION FROM AUTOMATED REFINING UNIT IN THE TEXAS PERMIAN BASIN

Libertystream Infrastructure Partners Inc. has achieved consistent production of lithium carbonate from its automated continuous-flow refining unit operating at its field site in the Permian basin, Texas. Independent third party laboratories have validated multiple batches of product.

Highlights

• Multiple consecutive batches of lithium carbonate produced from the field refining unit meeting target customer specifications, as validated by independent third party laboratories;

• This milestone represents completion of two of three near-term objectives previously outlined; customer sampling supported by certificates of analysis (COAs) is now under way;

• Following customer qualification, Libertystream plans to advance to bulk sampling and off-take discussions to support scale-up in 2026, targeting commercial volumes beginning in 2027.

This milestone follows the company's Dec. 1, 2025, announcement of first field production of lithium carbonate from oilfield brine and further demonstrates an integrated, end-to-end pathway that converts produced water into saleable lithium carbonate directly at the disposal well site. By pairing the refining unit with its proprietary direct lithium extraction (DLE) technology deployed on existing oil field infrastructure, Libertystream has de-risked key technical steps toward a scalable, repeatable development model it intends to expand across major U.S. basins, including the Permian and Bakken.

Lithium is designated a critical mineral in the United States, and establishing domestic supply chains remains a strategic priority for North American industry.

"Our team at Libertystream continues to advance our lithium carbonate refining capabilities, delivering consistent, specification-compliant product from our field refining unit," said Alex Wylie, president and chief executive officer of Libertystream. "With this progress, we are firmly positioned to expand across critical U.S. oil fields in the Permian basin in Texas and the Bakken in North Dakota."

Libertystream automated continuous flow refining unit results and strategy

Over the past 17 months, Libertystream's Texas field operations have successfully advanced the commissioning and scale-up of its proprietary Generation 5 DLE unit. The system is designed to process up to 10,000 barrels of oil field brine per day into a lithium chloride eluate. As previously reported in the company's Dec. 1, 2025, press release, since February, 2025 (through Nov. 30, 2025), Libertystream has processed more than 350,000 barrels of brine and completed over 2,500 real-time validation tests, demonstrating the strength, consistency and reliability of its technology platform.

In the past month, the Libertystream team achieved another milestone by consistently converting its lithium chloride eluate into lithium carbonate that meets target technical specifications provided by prospective industrial customers (subject to customer qualification testing). Multiple batches have now been produced and independently validated by third party laboratories, fulfilling two of the company's three near-term objectives outlined in its Dec. 1, 2025, press release.

• Objective 1: independent third party validation of lithium carbonate produced from field operations -- completed;

• Objective 2: consistent production meeting target specifications -- completed;

• Objective 3: customer qualification supported by COAs and delivery of bulk samples -- under way.

The team is currently preparing customer samples accompanied by certificates of analysis (COAs) for qualification testing. Following customer validation of the COAs, Libertystream will begin delivering bulk samples to prospective buyers.

Upon successful customer qualification, the company plans to initiate off-take discussions with strategic partners. Libertystream's objective is to secure agreements that will underpin the scale-up of lithium carbonate production in 2026, with the goal of supplying commercial volumes to customers beginning in 2027.

In the interim, Libertystream intends to sell all lithium carbonate produced-outside of customer sampling -- into the spot market in 2026 from its refining unit operating at its Texas field site.
