CALGARY, Alberta & DALLAS--(BUSINESS WIRE)--Oct 23, 2025--

LibertyStream Infrastructure Partners Inc. (TSXV: LIB | OTCQB: VLTLF | FSE: I2D) (“ LibertyStream ” or the “ Company ”) is pleased to announce continued progress on the installation of its lithium carbonate refining unit (the “Refining Unit”) in Texas, a key milestone in its strategy to scale domestic lithium production. In parallel, the Company and North Dakota partner, Wellspring Hydro has been awarded a US$500,000 grant from the State of North Dakota to support the development of in-state lithium carbonate production for future battery cell manufacturing. Together, these initiatives reinforce LibertyStream’s commitment to building a vertically integrated supply chain for high-purity lithium carbonate sourced from its field operations in Texas and future sites in North Dakota.

LibertyStream's lithium refining unit located adjacent to extraction facilities in the Permian Basin, West Texas.

“We remain on schedule to initiate commercial lithium carbonate production with the installation of our Refining Unit in Texas,” said Alex Wylie, President & CEO of LibertyStream . “ We’re also honored to receive continued support from the State of North Dakota, which enables us to expand our refining capabilities and advance in-state lithium carbonate production to support future battery cell manufacturing.”

Installation of Lithium Carbonate Refining Unit

LibertyStream announced the purchase of its lithium carbonate refining unit (the “Refining Unit”) in July 2025. By early October, the Company had initiated site preparation activities in Texas to accommodate the Refining Unit, marking a critical step toward commercial production. As of this update, installation of the Field Unit is substantially complete, and LibertyStream has officially entered the commissioning phase.

Once operational, the Refining Unit will be capable of producing up to 10 tonnes per annum (tpa) of lithium carbonate, engineered to meet the technical specifications of future customers across both industrial-grade and battery-grade applications. To support qualification and offtake discussions, bulk samples sourced from the Texas field site will be made available to prospective customers. Management expects the Refining Unit to deliver consistent, high-quality output, enabling customers to confidently assess product grade and reliability for long-term supply agreements

North Dakota Renewable Energy Program Grant

The Renewable Energy Program (“REP”) has awarded LibertyStream and its North Dakota partner, Wellspring Hydro, a grant of US$500,000 to support the validation of battery-grade lithium carbonate for deployment within the state (the “ND Grant”). The grant is intended to advance regional lithium production capabilities and accelerate commercialization of high-purity lithium for energy storage applications. Final confirmation of the ND Grant is scheduled for October 27, 2025.

The ND Grant will be deployed to complete the next step of commercialization including site specific lithium extraction qualification and associated high value 3rd party testing. A major emphasis will be on lithium refining validation and samples creation with a purpose to prove the capability to meet the required quality and quantity of Lithium Carbonate for customers. The primary focus of validation of the lithium carbonate testing will ensure LibertyStream can meet the short and long-term product requirements for a battery cell manufacturing facility in North Dakota. The validation work will be performed in conjunction with the University of North Dakota and cathode cell manufacturers. This output will create a full life-cycle lithium ecosystem inside North Dakota from lithium extraction to battery manufacturing, with the potential to make the state a key player in the evolving and expanding energy market.

North Dakota Renewable Energy Program

North Dakota's Renewable Energy Program (REP) was established by the Legislature in 2007 under the control of the North Dakota Industrial Commission. The law provides that the Industrial Commission shall consult with the Renewable Energy Council (REC). The Program's responsibilities include providing financial assistance as appropriate to foster the development of renewable energy and related industrial use technologies including, but not limited to, wind, biofuels, advanced biofuels, biomass, biomaterials, solar, hydroelectric, geothermal, and renewable hydrogen through research, development, demonstration and commercialization. In addition, the Program shall promote research and utilization of renewable energy co-product utilization for livestock feed, human food products and industrial use technologies.
