Clear Sky's Eli clay results to serve as study baseline

2022-11-11 22:16 ET - News Release

Mr. Patrick Morris reports

CLEAR SKY COMPLETES CLAY STUDY AT THE ELI PROJECT

Clear Sky Lithium Corp. has released clay speciation lab results from surface sampling at its Eli property located in Nevada's Little Smoky Valley.

Company chief executive officer Patrick Morris observed: "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 tool box approach for exploration and processing."

As noted previously on Oct. 11, 2022, ActLabs of Ancaster, Ont., which is a specialist in geochemical and geometallurgical characterization testing, was engaged to process four 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 Aug. 26, 2022, "Clear Sky Lithium Reports 1,023 ppm 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 percentage of corundum, and the rest to 100 per cent was considered poorly crystalline and X-ray amorphous material. The relative proportions of the clay minerals in the fewer-than-four-micrometre-size fraction were calculated using the ratios of the basal peak areas.

The resulting quantitative X-ray diffraction (XRD) displayed mineral abundances.

The clay speciation displayed several types of clay in the fewer-than-four-micrometre-size fraction.

Mr. Morris continued, "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."

Qualified person

Anna Hicken, PGeo, of Geomax Consulting, a consultant to the company, is the qualified person as defined in National Instrument 43-101, and has reviewed and approved the scientific and technical content of the press release.

Notes

All samples were sent to Activation Laboratories located in Ancaster, Ont. ActLabs quality systems conform to requirements of ISO/IEC Standard 17025 guidelines and meet 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 were dispersed in distilled water, and the clay minerals in the fewer-than-four-micrometre-size fraction were separated by gravity settling of particles in suspension. The fewer-than-four-micrometre-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 a copper X-ray source. The PDF4/Minerals ICDD database was used for mineral identification.
