R. V. Allen, W. E. Davis
1969, Open-File Report 69-6
Introduction Geophysical studies were continued in the Bi'r Idimah-Wadi Wassat area during February 1965. Detailed electromagnetic measurements were made along selected traverses over the northern part of the gossan to supplement earlier dip-angle data; and reconnaissance surveys were made over the central and southern parts of the gossan.

Anomalous concentrations of gold were found to exist in the wall rocks adjacent to mineralized veins. In general, the...
