Geologic descriptionThe following geologic description is taken from Freeman and others (1988, p. 16): Mineralization in the roadcut of the Steese Highway within the Bear claims consists of massive to disseminated arsenopyrite and lesser pyrite. The sulfide minerals are hosted by a sequence of chloritic greenschist overlain by black calcareous, graphitic schist overlain by micaceous quartzite. The sequence is folded into open folds whose axes plunge gently south with wavelengths of approximately 150 feet and amplitudes of approximately 30 feet. The crests of anticlines are cut by stockwork quartz veins stained by abundant scorodite. The rocks are pervasively oxidized along vertical shear zones which strike N 40 E. The shears contain oblong fragments of highly altered granite which are also mineralized with arsenopyrite and pyrite and are heavily stained with scorodite. A sixty-five foot section of one of the most highly mineralized anticlinal structures was channel sampled at five foot intervals. The maximum gold value for these channel samples is 0.092 ounces per ton, but several others have gold values ranging from 0.012 to 0.017 ounces per ton.
