CALGARY, Alberta, Dec. 18, 2024 (GLOBE NEWSWIRE) — Volt Lithium Corp. (TSXV: VLT | OTCQB: VLTLF) (“Volt” or the “Company“) is pleased to announce the achievement of another pivotal milestone on the path to commercializing its proprietary and proven next-generation Direct Lithium Extraction (“DLE”) technology for processing oilfield brines. The Company has scaled-up its U.S. field operations to process over 2,500 barrels per day (“bbls/d”) (equivalent to 480,000 litres per day) from the Permian Basin in Texas. Additionally, Volt has completed over 200 operational runs in the field since commencing operations and achieving first lithium production in September 2024.

“The Permian Basin is globally significant, currently producing approximately 19 million barrels of lithium-infused brine per day, making it one of the largest potential sources of lithium in the United States,” commented Alex Wylie, President & CEO of Volt. “With the scaling-up of our field operations, we continue to accelerate the Company’s trajectory for growth to becoming a significant North American lithium producer.”

“The experience gained in the field through Volt’s first 200 operational runs has been invaluable,” added John McEwen, CTO of Volt. “The Volt engineering and operational teams have leveraged the technical data acquired from field operations to significantly optimize Volt’s next generation system (“Generation 5”) that will produce up to 10,000 barrels of oilfield brine per day.”

Permian Basin Field Operations Update: Continued Field Unit Optimization

Volt’s U.S. Field Unit (“Field Unit”) is modular, providing the flexibility for continued optimization. Since commencing field operations in September 2024, Volt has focused on accumulating technical data to continuously optimize its Field Unit. The operations team has completed over 200 runs of the Generation 3 and 4 Field Units at our Strategic Partner’s site in the Permian Basin in Texas to date. The Generation 5 Field Unit will be commissioned in late January 2025 to process up to 10,000 bbls/d (1.9 million litres per day).

The technical and operational data and improvements have been critical building blocks to Volt’s scale-up process in the field. The system modifications made by the operations team have been incorporated into the Generation 5 Field Unit system, include the following:

• DLE System Optimization: Design modifications to Volt’s DLE system to enhance drainage, allowing for increased daily processing capacity; and
• Acid Recovery Refinement: Modifications to the acid recovery phase have successfully increased the concentration of lithium in the lithium chloride eluate, while also decreasing cycle times. Volt’s technical team is dedicated to further refining the acid recovery process to maximize lithium concentration and extraction efficiency. This ongoing optimization is expected to enhance the overall economic performance of Volt’s Generation 5 Field Unit.

Through the scale-up of Volt’s production capacity, the technical standards of achieving up to 98% lithium extraction have been maintained and verified by an independent third-party.

Since October 2024, Volt’s proprietary DLE process has successfully built up an inventory of high-quality eluate that is being converted into a 99.5% pure battery-grade lithium carbonate. Samples of lithium carbonate have been created and verified via third-party testing for review for potential offtake partners. Volt will continue to produce lithium chloride concentrate, as well as technical-grade and battery-grade lithium carbonate in the field.

Permian Basin Brine Production

The brine production from the Permian Basin today is approximately 19 million bbls/d, representing an estimated potential of 325,000 tonnes per annum of lithium carbonate production. Assuming average economics from lithium extraction, sensitivities are as follows at potential production levels and lithium concentrations ^1,2.

North Dakota Field Unit Update

Volt has utilized the funding from the State of North Dakota to purchase the equipment for the North Dakota field unit. The field unit is fully funded and the Company expects to deploy the North Dakota field unit during the first half of 2025. Volt and Wellspring will apply for an additional US$2.0 million of funding for the field study from the State of North Dakota in early 2025. Volt will not require any new financing for the field unit in North Dakota.
