|Location and accuracy||This old claim is about one-half mile west of the head of the West Arm of Cholmondeley Sound. The exact location is vague; for this record, it is arbitrarily plotted about 0.6 mile south-southwest of the center of section 22, T. 76 S., R. 85 E. This location is probably accurate to within 0.5 mile.|
Geologic descriptionThe only published description of the deposit at this prospect is by Brooks (1902), who describes it as 'disseminated quartz blebs which carry iron pyrite' in quartz schist associated with graphitic phyllite. There were no assays. The rocks in the area are part of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996).
