Gold Line Resources Ltd. announced that it has completed Phase 1 (of 2) of an unmanned aerial vehicle magnetic survey over its 100% owned ~17,600 Hectare Oijärvi Greenstone Belt Project in northern Finland conducted by Radai Oy based in Oulu Finland. The aim of the survey is to collect data in order to map underlying geology and structural architecture over the entire greenstone belt and determine priority target areas for its 2022 exploration programs and beyond. Gold Line commissioned Radai Oy, an industry leader in UAV magnetic surveys, to conduct the survey.

The Phase 1 survey consisted of 2,100 line km over the northern and western portions of the Oijärvi greenstone belt. The central portion of the belt will be flown in early fall in cooperation with local indigenous groups reindeer calving schedules. UAV aeromagnetic geophysical surveys consist of flying an unmanned drone fitted with a magnetometer measuring the intensity of the geomagnetic field over the ground that it flies to detect local magnetic variations between different geological units and structures.

The Oijärvi greenstone belt has been subjected to at least two recent glaciation events, depositing extensive glacial till cover over the underlying bedrock ranging from zero in the north to >30 m in some areas of the south. The glacial till layer transports and masks the geochemical signal of bedrock hosted mineral deposits and limits direct field observation of geological and structural information.
