Mainly drift covered and with sparse outcrop, the Toil Mountain area remains underexplored despite being underlain by the Stikine terrane island-arc assemblage, which has high potential for mineralization. Basal tills have a relatively simple transport and depositional history, thus are an ideal sampling media to explore for buried deposits. This basal till potential map is designed to help plan exploration projects in drift-covered areas by guiding surficial sediment geochemistry and mineralogy sampling programs to where basal till is most likely to occur.
Current work in the Toil Mountain map area is part of Geoscience BC's Targeting Resources for Exploration and Knowledge (TREK) project. The basal till potential map presented here is one of a series of 10 maps that were completed for the TREK geochemical program.
