Clear Sky Initiates Extraction and Processing Test Work

VANCOUVER, Nov. 18, 2022 - Clear Sky Lithium Corp. (CSE: POWR) (FRA: K4A / WKN: A3DM2W) ("Clear Sky" or the "Company"), a mineral exploration and development company focused on American lithium deposits to support domestic demand, is pleased to announce that it has shipped material to initiate bench scale test work with MDS Technical Corp ("MDS") for the extraction and process testing of lithium from claystone.

Building on the field sample program announced August 26, titled Clear Sky Lithium Reports 1,023ppm Li Grab Sample, and, as part of the ongoing field work plan, bulk sampling was conducted at key locations on the ELi and Halo properties. These materials have now been prepared and select samples are in transit to MDS for processing via their proprietary and patented process to leach, concentrate, and purify lithium from claystone and, ultimately, to produce battery grade lithium carbonate.

Company CEO, Patrick Morris, observes, "This is a positive step forward in our overarching process development goals. Processing claystone-based lithium has historically proven challenging. While more than 50% of the undeveloped US lithium projects with established resources are clay associatedⁱ, none of them to date have reached commercial production. Clear Sky intends to leverage MDS's experience and technology to unlock a cost effective and clean lithium extraction process."

MDS brings over 40 years of developing solutions that have spread across almost every continent. Led by Larry Lien, the company has a proven track record of developing solutions to highly complex challenges. MDS has provided solutions to a number of industries such as wastewater management, oil & gas, mining, and metals processing sectors. With the heightened interest in lithium mining, and specifically the potential for domestic claystone production, MDS has developed key solutions utilizing its patented processes for the extraction and processing of lithium from some of the most challenging host materials, such as claystone.
