Feasibility Study of Placer Gold Mining in the White Mountain Area, Circle and Tolovana Mining Districts, Alaska

摘要

The Bureau of Mines (Bureau) performed a placer mineral resource assessment and mining feasibility study for the White Mountains Area north of Fairbanks, Alaska in 1987. The mining feasibility study involved a cost analysis and cash flow determination for three types of placer mine models. The basic mine model design incorporated the use of dozers and loaders for material handling, vibrating screens and sluicing systems for ore processing, and gold saver type equipment for concentrate cleanup. Settling ponds were used in the mine design for effluent treatment.
