Richardson mining district geologic mapping

Project Details

---

• Project ID:

  1538

• Nickname/Abbreviation:

  Richardson

• Parent Project:

  Mineral Resources Section projects

• Status:

  Active

• Description:

  Geologic mapping and sampling of part of the Richardson Mining District, southeast of Fairbanks, including parts of the Big Delta B-4, B-5, and C-5 quadrangles. The project area is about 30 miles west of the Pogo gold mine and covers gold exploration activity at the Montecristo and Uncle Sam properties. The goal of this work is to build an improved understanding of the project area geology and controls on gold mineralization for purposes of exploration targeting and mineral resource assessment.
