Fortymile Placer District Resource Inventory, Alaska

Details

• Personal Author:
  Colp DB
• Description:
  The Fortymile Placer District comprises the Alaska part of the Fortymile River Drainage Basin, the Eagle District, and the Seventymile River Drainage Basin. Most of the district is underlain by preCambrian and Paleozoic gneiss and schist, of both sedimentary and igneous origin and minor crystalline limestone, and by Paleozoic, Mesozoic, and Tertiary Felsic, Mafic, and Ultramafic igneous rocks. Gold in the placers is the result of weathering away of many mineralized quartz veins in metamorphic rocks near contact with Felsic intrusive bodies. This report presents a resource inventory based on records research, visits to various parts of the Fortymile area, information accumulated by miners, personal interviews, and other publications.
