The silt plus clay-sized fraction of 84 basal till samples collected within the Colleymount map area (093L/01), located approximately 40 km southeast of Houston, BC, was analyzed for 37 elements by inductively coupled plasma mass spectrometry (ICP-MS), following an aqua regia digestion, and 35 elements by instrumental neutron activation analysis (INAA). An additional 18 basal till samples were collected for analysis of heavy metal concentrates and gold grain counts. The spatial distribution of till samples elevated in Cu, Mo, Pb, Zn, Ag, Hg, Au, As, Sb, and visible gold grains are the focus of this study. Detrial dispersal of commodity metals and pathfinder elements from known sources of mineralization is discussed (e.g., past producing Equity Silver mine) as are areas of geochemical interest.
