Till (n=196) and stream sediment (n=60) samples were collected in the area south and west of Great Slave Lake, Northwest Territories (NTS 85B, C, F, and G), over the course of 3 summer field seasons. Samples were processed to recover kimberlite and other
indicator minerals. This report summarizes results of the kimberlite indicator mineral (KIM) studies, including measures of KIM mineral types, abundances, and chemistry (major, trace, and rare earth elements). KIMs were present in 24% of the samples collected, and only 183 KIM grains in total were
recovered, of which Cr-pyrope garnets were the most abundant (65.6%). Chemical analyses revealed strong similarities to the Drybones Bay and Mud Lake kimberlites which are situated 50 to >100 km to the northeast, roughly aligned with prominent glacially streamlined landform flowsets in
this field area. Results suggest there is little evidence for undetected kimberlite outcrop or sub-crop in the study area.
Regional stream sediment and water geochemical data, Horn Plateau area, Northwest Territories (parts of NTS 85E, 85F, 85K, 85L, 95H, 95I and 95J) including analytical, mineralogical and kimberlite indicator mineral data
