[{"type":"text","content":"Canarc Reviews Results of Airborne Geophysical Surveys Flown Over the Hard Cash Property in NunavutVANCOUVER, BC / ACCESSWIRE / June 19, 2019 / Canarc Resource Corp. (TSX: CCM, OTC-QB: CRCUF, Frankfurt: CAN) reviews the results of the airborne magnetic and radiometric geophysical surveys flown by Geotech Airborne Geophysical Surveys late last year over the Hard Cash Property in Nunavut.Geophysical modelling and interpretation were recently completed by Geotech, followed by geological and structural interpretation by company geologists. The results have clarified the broad geological and structural controls on gold mineralization and will help guide the Phase 1 exploration program planned for this summer to identify and prioritize drill targets.MagneticsThe Total Magnetic Intensity (TMI, link 1) is used to broadly interpret lithological units and structural fabric. It shows a strong northeast-striking linear structural fabric that coincides with the strike of the main metavolcanic and metasedimentary units.Five main magnetic domains trend northeasterly across the property and can generally be correlated with the main rock units shown on the Geological Survey of Canada regional geological map of the area. From northwest to southeast, these are:  Domain 1 - broad belt of high magnetics mapped as metasediments and paragneiss Domain 2 - broad belt of low magnetics mapped as felsic and mafic metavolcanics Domain 3 - narrow belt of high to very high magnetics mapped as mafic metavolcanics bounded to the south by a major linear interpreted as a major structure or break Domain 4 - broad belt of very low to moderate magnetics mapped as mafic and felsic metavolcanics Domain 5 - three irregular ellipsoids with high to very high magnetics mapped as granitic intrusions The First Vertical Derivative (FVD, link 2) is used to interpret primary and secondary structures or breaks and it shows four main linear trends:  Trend 1 - southwest-northeast (NE) overall trend of lithologies and structures, including a major break dividing Domain 3 and Domain 4, which marks the northern margin of the main Swamp high grade gold vein zone Trend 2 - west-northwest (WNW) transverse structures, including one main linear feature which crosses the main Swamp high grade gold vein zone and coincides with the southwest margin of the granitic intrusion s...
