New publication: updated bedrock geologic mapping in the Yukon-Tanana Upland!
The publication includes four 1:100,000 scale map sheets NW Chena, NE Chena, SW Chena, and SE Chena. The map units used across the four maps are described in this report.
"The project area has been a focus of gold exploration for several decades but also has additional significance for its potential to host critical minerals such as antimony, bismuth, tellurium, and tungsten."
