Geochemical data from regional geochemistry survey samples from Yukon have undergone exploratory data analysis and principal component analysis. The results of these analyses clearly demonstrate geological control on the distribution of a number of important commodity and mineral deposit pathfinder elements. Catchment basins have been delineated for the samples and the dominant simplified geological unit in each catchment basin used to level the geochemical data where appropriate. Levelling the geochemical data in this fashion generally fails to fully account for enrichments in many commodity and mineral deposit pathfinder elements in the bedrock due to practical limitations on the resolution of the mapping and knowledge of the relative contributions of different geological units, although the resulting data interpretation is an improvement on one based solely upon raw geochemical data. Weighted sums models have been generated for the deposit types that either exist within the individual map areas covered by this report or are considered by the authors to be of exploration significance. Separate catchment maps showing the distribution of stream water pH and the concentration of…
