Samples provide baseline for upcoming extraction test work
VANCOUVER, BC, November 11, 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 clay speciation lab results from surface sampling at its ELi property located in Nevada’s Little Smoky Valley.
Company CEO, Patrick Morris, observes, “These initial findings give a baseline for the previously announced upcoming bench scale study to be performed by MDS Technical Corp., the results will be used to further characterize and refine our metallurgical plan and forms an integral part of our ongoing toolbox approach for exploration and processing.”
As noted previously on October 11, 2022, ActLabs of Ancaster, Ontario who are specialists in geochemical and geo-metallurgical characterization testing, were engaged to process four (4) surficial grab samples collected from the Clear Sky ELi property in the summer of 2022. The lithium results from these samples were previously press released on August 26, 2022 – Clear Sky Lithium Reports 1,023ppm Li Grab Sample.
The four samples were submitted for a quantitative X-Ray Diffraction (XRD) and clay speciation whereby ActLabs determined the relative abundance of clay minerals. The quantities of the crystalline mineral phases were determined using the Rietveld method based on the calculation of the full diffraction pattern from crystal structure data. The amounts of the crystalline minerals were recalculated based on a known percent of corundum and the remainder to 100 % was considered poorly crystalline and X-ray amorphous material. The relative proportions of the clay minerals in the < 4 μm size fraction were calculated using the ratios of the basal-peak areas.
The resulting quantitative X-Ray Diffraction (XRD) displayed the following mineral abundances (wt%) (Table 1):

The clay speciation displayed the following types of clay in the <4 µm size fraction (Table 2).

Patrick Morris, continues, “We are very pleased and look forward to starting the MDS bench scale test program and announcing the results of our continued efforts to expand our knowledge and ability to unlock the intrinsic value of lithium at our properties in Nevada”
Anna Hicken, P.Geo., of Geomax Consulting and consultant to the Company, is the Qualified Person as defined in NI 43-101 and has reviewed and approved the scientific and technical content of the press release.
All samples were sent to Activation Laboratories (ActLabs) located in Ancaster, Ontario. ActLabs quality systems conform to requirements of ISO/IEC Standard 17025 guidelines and meets requirements outlined in NI 43-101.
For the quantitative XRD analysis, a portion of each pulverized sample was mixed with corundum and packed into a standard holder. Corundum was used as an internal standard. For the clay speciation, a portion of the samples was dispersed in distilled water and the clay minerals in the <4μm size fraction separated by gravity settling of particles in suspension. The <4μm size fraction was analyzed dried and after treatment with ethylene glycol.
The X-ray diffraction analysis was performed on a Bruker D8 Endeavour diffractometer equipped with Cu X-ray source. The PDF4/Minerals ICDD database was used for mineral identification.
