North Dakota Field Trial

Article content

The purpose of the Field Trial was to compare the performance and efficacy of the Field Unit against previously validated pilot trials performed at LibertyStream’s Research and Development Centre in Calgary, Alberta, Canada. The results from the Field Trial confirmed the performance of the Field Unit against the performance at the Research and Development Centre by achieving an average 96% lithium extraction rate from Bakken‑region oil‑field brine. The field trial was conducted at Compass Energy System’s (“Compass”) Blue Marlin salt-water-disposal facility (“SWD”) in North Dakota.

Strategic Significance: North American Lithium Leadership

Article content

LibertyStream has conducted field operations in North America’s two most prolific onshore oil-producing basins—the Permian in Texas and New Mexico, and the Bakken in North Dakota. Together, these basins represent over 60% of total U.S. onshore oil output, providing significant opportunities for lithium extraction from extensive lithium-rich produced water volumes.

Article content

The Permian Basin generates approximately 19 million barrels per day of produced water at lithium concentrations averaging around 30 ppm, translating to a conservative 170,000 tonnes per annum (“tpa”) of potential LCE.

Article content

The Williston Basin Bakken production ranges from 1.6 million to2 million barrels of produced water per day, suggesting potential production of ~50 000 tpa LCE.

CEO Commentary:

Article content

“The North Dakota Field Trial provides further supporting evidence of the robustness of the Technology we have developed at LibertyStream. This milestone builds on six months of intensive operations in Texas, during which the company completed over 1,300 DLE runs, demonstrating robust and scalable technology readiness. These trials are instrumental to our strategy and showcase the continued progress toward transforming lithium extraction in a responsible, capital-light and high-efficiency manner as we transition to commercial operations in America.”
