Frontier Lithium Inc. announce results from the 2022 mapping campaign at the PAK Lithium Project. The mapping program delivered several key results, including: Discovery of a new pegmatite zone approximately 1km WNW of the Spark deposit; Two grab samples with an average grade of 3.1 % Li2O, Significant expansion of the Pennock Pegmatite showing; Three grab samples grading 1.7%, 1.7%, and 3.0% Li2O Generation of prospective targets to be followed up in future regional mapping and prospecting programs. Between the months of May and August, Frontier Lithium conducted both detailed and regional mapping and prospecting in areas both proximal to known spodumene-bearing pegmatites and in under-explored areas within its approximately 27,000 hectare land tenure with the following objectives: Ground-truthing regional work at 1:50k scale previously completed by Ontario Geological Survey (OGS)Reconnaissance prospecting for new lithium bearing pegmatites Further investigation of known lithium bearing pegmatite showings. As many as 33 areas classified as pegmatite, pegmatite veins etc. (white crosses) have been identified and require follow-up. Geochemical analysis was completed on 38 grab samples. Table 1 is a summary of the grab samples from the Pennock and Spark-Ext areas. A new LCT pegmatite showing 10 x 15m, was discovered approximately 1 km WNW of the Spark Pegmatite (See inset map in Figure 1 (Station 22TG0050)). The spodumene-bearing pegmatite is surrounded by mafic volcanic host rock and contains aplitic to pegmatitic zoning with a mineral assemblage of spodumene, quartz, muscovite, +-lepidolite and garnet. These characteristics are all analogous to the Spark deposit and follows the same general trend of all currently discovered LCT pegmatites in the project area. Pegmatite veins with similar mineralogy and texture can be traced up to 6km NW of Spark. the outcrop and a close-up of the typical "snowshoe" textures of the SQUI (spodumene quartz intergrowths).
Additional mapping and prospecting proximal to the Pennock LCT pegmatite uncovered additional Li-bearing pegmatites, including three up to 30m in length. The Pennock showing which was previously defined as a 1.5 km-long pegmatite dike, has increase significantly in size, despite the low outcrop exposure. The inset map in Figure 1 shows the location of two of the larger pegmatite outcrops both with grab samples averaging 1.7% Li2O. Station 22EB0109 with a grade of 3.0% Li2O is from the original Pennock showing. Figure 3 shows the two southern outcrops (Stations 22EB0128 and 22EB0130) with grabs samples each grading 1.7% Li2O. All scientific and technical information in this release has been reviewed and approved by Garth Drever, P.Geo., the qualified person (QP) under the definitions established by National Instrument 43-101. During the mapping program representative samples were routinely collected using rock hammers, however, it should be noted that because of the nature of some outcrop surfaces, an optimum sample was difficult to obtain. Sample blanks along with lithium, rubidium and cesium certified reference material was routinely inserted into the sample stream in accordance with industry recommended practices. Field duplicate samples were also taken in accordance with industry recommended practices. The samples were placed in poly sample bags and transported to Red Lake by float plane and then shipped to AGAT Laboratories Ltd. (AGAT) in Thunder Bay for sample preparation and to Mississauga, Ontario for processing and quantitative multi-element analysis. AGAT is an ISO accredited laboratory.
