One World Lithium Inc. (CSE:OWLI, OTCQB:OWRDF), the mining exploration company, has received a one-year extension of its non-exclusive research and evaluation license with the US Department of Energy.
Granted by the energy department’s National Energy Technology Laboratory (NETL), One World Lithium will see the license extended to March 1 2025 for the patent titled “Selective Lithium Recovery as Lithium Carbonate from natural brine”.
“We are pleased to have signed a one-year extension with NETL. The extension will allow One World Lithium and NETL to evaluate commercial applications of the DOE’s two patents for Lithium Carbonate Extraction,” president and chief executive Doug Fulcher said.
In September last year, the Canadian company entered into a definitive agreement with MatterGreen LLC in which the latter will assign two patent applications for lithium carbonisation.
The first patent relates to natural brines, while the second is for slurries made from pegmatite, clay, volcanic rock and sediment.
Following the assignments, One World Lithium will become the sole owner of these patent applications, with MatterGreen undergoing the development, research and lab work associated with commercialisation.
“By consuming carbon dioxide from industrial waste streams and air in carbonation processing, the process can produce carbon-neutral lithium carbonate for battery cathode manufacturing, which would generate a premium on the market price,” MatterGreen said.
