Mainly drift covered, the Hulatt area is thought to be underlain by Cache Creek terrain, a belt of oceanic crustal and sedimentary rocks that separates Stikine terrane (to the west) and Quesnel terrane (to the east). These two neighbouring island-arc assemblages have high potential for mineralization, but because of sparse outcrop, the area remains underexplored. 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 Hulatt 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.
