Basal till potential of the Downton Creek map area (NTS 093C/10), British Columbia

(also Geoscience BC Map 2017-02-03)
Mainly drift covered and with sparse outcrop, the Downton Creek 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.
Work in the Downton Creek 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 16 maps that were completed for the TREK geochemical program (see index map below).
