The number of kimberlite discoveries in the Slave Geological Province has decreased over the last decade. There is a significant opportunity to change this trend by focusing on the numerous orphaned kimberlite indicator mineral (KIM) dispersals that occur within, and peripheral to, the Lac de Gras kimberlite field. Many of these orphaned KIM dispersals are overprinted by complexities within the surficial environment that obfuscate the primary dispersal vector, making it difficult to identify drill targets and less desirable for investment. The increased availability of high-resolution datasets and drill-supported sampling methods provide a new perspective into complex surficial environments that can help unravel the path to kimberlite. Using work completed on the infamous Coppermine mineral train as an example, this talk highlights recent insights into dispersal-scale data collection and evaluation methods and identifies new opportunities that will help untangle the mystery of the orphaned KIM trains.
