(TSX.V: FL) (the \"Company\") is pleased to announce results from the confirmation of a historical showing of the Pennock Lake Pegmatite on the PAK Lithium Project (\"The Project\"), located 30 km north-west of the PAK deposit (Figure 1). The showing is an LCT (Lithium Cesium Tantalum) pegmatite intruding vertically into granitoids and metavolcanics. It was confirmed in the final days of a geological mapping program in late September 2018. It was originally described by L.D. Ayers (Ontario Geological Survey; Ayres et al., 1972) as \"fine-grained spodumene….in a white pegmatite dike\" Figure 1: Location Map of the Pennock Lake Pegmatite showing historical showings. (To view the full-size image, please click here)Initial mapping and sampling indicate zones that appear similar to the Lower Intermediate Zone at the PAK Deposit. Aplite, feldspar and spodumene is common throughout the outcrop exposure. Grab sample from the north-west outcrop contain 4.41% Li2O.The Company cautions that the grab sample result may not be indicative of the body being sampled. Figure 2: The Pennock Lake Pegmatite outcrop was visited in September 2018. The outcrop's exposure is limited by vegetation but currently measures approximately 30 x 16 m and consists entirely of spodumene + quartz intergrowth (SQUI). (To view the full-size image please click here (left) and here (right))Limited EMP (electron microprobe) work was completed on spodumene from polished thin sections from one grab sample collected at the pegmatite outcrop. The results indicate similar Na2O and Al2O3 content for spodumene as the PAK Deposit. The iron oxide (Fe2O3) content of spodumene from this initial w...
