[{"type":"text","content":"International Lithium Reports on 2019 Raleigh Lake UAV Magnetic Survey ResultsVancouver, British Columbia--(Newsfile Corp. - October 1, 2019) - International Lithium Corp. (TSXV: ILC) (the \"Company\" or \"ILC\") is pleased to announce the receipt of the final results from an unmanned aerial vehicle magnetometer (\"UAV-MAG\") survey designed to collect high-resolution magnetic field data over the Raleigh Lake project area. The resulting magnetic images confirm that a geologic body with elevated magnetic response, previously interpreted to be a gabbroic intrusive hosting the lithium bearing pegmatites, continues onto the adjacent group of claims acquired by ILC in 2018.The 2019 UAV-MAG survey was conducted by Pioneer Aerial Surveys Ltd., a subsidiary of Global UAV Technologies Ltd. It covered a total of just under 500 line-kilometres using a 40 metre line spacing. The data were merged with the 2016 UAV-MAG survey which covered an additional 189 line-kilometres for almost 700 line-kilomtres of continuously profiled magnetic data recorded at an approximate ground clearance of 50 metres.A map showing a gridded image of the merged data sets is given in Figure 1. The magnetic body interpreted to be the gabbroic host to the pegmatites is clearly visible in the eastern-central portion of the map. It measures approximately 3 kilometres by 1 kilometre which is comparable in size to the gabbroic rocks hosting the mineralized pegmatites at the Tanco mine.The Two-mica granite is coarsely mapped in at the south-western extent of the survey area. It is thought to be the parental magma source for the spodumene bearing pegmatites at Raleigh Lake. It is located between four and six kilometres from the gabbro indicating that the gabbro is the optimal distance from the magmatic source body for fractionation to favor the crystallization of spodumene, a lithium rich mineral (Figure 2).Several regional structures can be interpreted from the magnetic image shown in Figure 1. Some of these strucures transcend from the Two-mica granite to the Raleigh Lake gabbro. The structures cut the gabbro at its northern terminus, in the vicinity of the historic drilling, and in the central (thickest) portion of the body. No drill holes have tested the main gabbro body and all the historic drill holes at the terminus have intersected spodumene bearing pegmatites that...
