Volt Lithium Announces 93% Lithium Recoveries From Its Proprietary Dle Technology

24.01.2023  |  GlobeNewswire
Vancouver, Jan. 24, 2023 - Allied Copper Corp. (TSX-V: CPR, OTCQB: CPRRF) ("Allied"), is pleased to announce that its lithium-focused division, Volt Lithium Corp. ("Volt" or the "Company") has achieved 93% lithium recoveries from its proprietary extraction technology, called IES-200. Further, using its proprietary oilfield brine treatment system, Volt has also been able to successfully remove 99% of contaminants from oilfield brines, which is critical to ensure high purity levels required for salable lithium.

"The Volt team has achieved a technological breakthrough by demonstrating the ability to recover up to 93% of lithium from oilfield brines using our proprietary IES-200 direct lithium extraction technology." commented Alex Wylie, President of Allied and founder of Volt. "These independently verified results provide Volt with the confidence we were seeking to commence pilot production by the end of the first quarter of 2023 and accelerate development of our Rainbow Lake assets in Alberta."

Proprietary DLE Process

Volt uses a two-stage process to extract lithium from oilfield brine. In Stage One, the oilfield brine is treated using proven equipment to remove contaminants and prepare clean brine for the DLE process. In Stage Two, Volt uses the Company's proprietary IES-200 technology to extract the lithium from the brine and concentrate it into a lithium chloride solution that will ultimately be upgraded to lithium hydroxide, an essential raw material required for batteries, and in particular, electric vehicle batteries.

Stage One - Oilfield Brine Treatment Process

Volt has entered into a collaboration with its equipment supplier to treat, and then extract, lithium from oilfield brine produced at Volt's Rainbow Lake property (the "Volt Collaboration"). Over the past year, the Volt Collaboration has extensively analyzed and tested processes and systems to ensure the removal of all contaminants from the brine, resulting in a clean and pure brine feedstock needed to maximize recoveries through Volt's proprietary DLE process (the "Oilfield Brine Treatment System"). The Volt Collaboration originally treated oilfield brine in the lab before progressing to a bench-test of the brine using equipment that will ultimately be scaled for the upcoming pilot project.

The Volt Collaboration has proven the ability to successfully remove 99% of contaminants using its Oilfield Brine Treating System on a bench-scale basis. The results from both Volt and its equipment supplier followed stringent standard operating procedures implemented during the testing process. The results were analyzed and verified at an accredited independent commercial laboratory that has extensive experience analyzing oilfield brines.

Stage Two - Proprietary DLE Process

Volt's team, led by its Director of Technical Services, Dr. John McEwen, PhD (Chemistry), developed IES-200 as a proprietary DLE technology for extracting lithium from oilfield brine. To advance the utility and scale of IES-200, Volt signed a technical services agreement with Sterling Chemicals Ltd. ("Sterling") in early 2022 (the "Technical Services Agreement"). Sterling is a private, Alberta-based oilfield chemical technology company with a track record spanning more than 20 years. The Technical Services Agreement provides Volt exclusive 24/7 access to Sterling's lab domiciled within the Nanotechnology Research Centre in Edmonton, Alberta. Leveraging Sterling's team of PhD's, led by Dr. McEwen along with its world-class lab facilities, Volt has successfully developed IES-200, and designed a proprietary DLE process capable of driving higher lithium recoveries from oilfield brine.

Volt's IES-200 technology successfully extracted 93% of the lithium from oilfield brine with testing conducted under stringent standard operating procedures. Volt's equipment supplier also independently tested the technology, following the same operating procedures, and results from both tests were analyzed and then verified at the same accredited independent commercial laboratory referenced above. The IES-200 technology is undergoing bench-scale testing using equipment that will be deployed for the pilot program and subsequently scaled up for commercial production.

Volt's DLE Pilot Project

Based on a successful bench-scale test of the Oilfield Brine Treatment System and lithium recoveries achieved by Volt's IES-200 technology, the Company plans to enter into the pilot project by the end of the first quarter of 2023. In the initial stages of the pilot project, Volt intends to process up to 250,000 litres of oilfield brine into lithium chloride using IES-200.

Independently verified results from the Company's initial pilot project are expected to be provided by the end of the second quarter of 2023.
