Clear Sky Lithium Reports 1,023ppm Li Grab Sample

VANCOUVER, Aug. 26, 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 report sampling results for its 100%-owned ELi claystone lithium project located in central Nevada.

As part of the Company's initial efforts, surficial grab samples (n=4) were collected during a trip to the ELi site during Q2, 2022. The sampling focused on areas with limited alluvial cover that corresponded to claystone exposure on surface. Samples were collected using a combination of hand tools down to approximately 30cm in depth and were recorded in the QField app on an android tablet with a built in GPS. Samples field values were logged for location information of easting, northing, and elevation, as well as documentation of physical attributes as appropriate for each sample and location. The samples were subsequently securely transported to American Assay Labs facility in Reno, Nevada for analysis¹. Results are presented in Table 1 and Figure 1.

The recent fieldwork program follows up on the encouraging samples (n=150) previously released (June 15, 2022) that included values ranging from 45-801ppm lithium with an average grade of 292ppm as well as the historic sampling program which returned results ranging from 288-970ppm lithium with an average grade of 667ppm¹ and provided the impetus to advance the project as Clear Sky's candidate for entry into the lithium sector. See Figure 1 for an overview of sampling at the Eli project.

Company CEO Patrick Morris notes, "Our initial efforts at the ELi property are presenting strong early results which are highly encouraging. The Clear Sky technical team is already integrating these results for future program planning. We look forward to continuing to advance the ELi property using a toolbox approach that consists of a variety of different exploration and processing techniques with the ultimate goal of building value in the Nevada lithium sector."

Clear Sky Lithium is excited to be in Nevada, the heart of America's lithium discovery region. Within the state there are multiple advanced stage lithium projects, including the only operating lithium mine in the USA. The USGS first publication on sedimentary-hosted lithium (claystone lithium) wasn't until 1991, making it one of the newer deposit types in exploration.

Figure 1 - ELi Project Sampling Overview

The ELi property was first sampled in 2019 due to its geological setting in a sub-horizontal sequence of lacustrine, tuffaceous mudstones, claystones and siltstones deposited in the Little Smokey Valley. This sequence appears to be floored by more conglomeritic, tuffaceous rocks and capped by younger felsic volcanic rocks. This broad, north-trending valley formed in a closed basin near the southwestern margin of the Basin and Range physiographic province of Central Nevada.

The lithium-bearing rocks within the project area are referred to as tuffaceous horizons and other young tertiary sedimentary rocks in digital geologic models generated by the Nevada Bureau of Mines. This unit is believed to have a strong volcanic component. In northern Nye County, the unit is referred to as the Horse Camp Formation which correlates with the Esmeralda Formation in Mineral and Esmeralda Counties. It has also been correlated with older lake beds in southern Nye, Lincoln, Clark and Humboldt counties. It corresponds to units Ts3 and Tts from the 1978 State map and is present in all counties of Nevada.

Unlike brine-based lithium projects, sedimentary or "claystone" deposits offer advantages in terms of environmental impact by utilizing non-evaporative extraction methods resulting in a reduction in water usage in arid desert conditions. With the advent of new extraction and processing technologies combined with an upsurge of interest, activity, and capital investment in regional claystone mining, Clear Sky's processing technology focused strategic goal aligns with the company's comprehensive exploration and development plans.

^1.All sampling completed by Clear Sky within the exploration program are subject to a company standard of internal quality control and quality assurance programs which include the insertion of certified reference materials, blank materials and pulp duplicate analysis. All samples are sent to American Assay Labs located in Reno, Nevada where they are processed for lithium analysis by ICP-5AM48. American Assay Labs quality systems conform to requirements of ISO/IEC Standard 17025 guidelines and meets assay requirements outlined for NI 43-101. Data verification of the analytical results included a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to ensure accurate and verifiable results.

Surface claystone samples are selective in nature and may not represent the true grade or style of mineralization across the entire property.
