|Location and accuracy||The location of the Anderson prospect as given by Brooks (1902) is unambiguous, although the deposit has hardly been mentioned since. It is east of Sunny Cove and about a mile north of Sunny Point, in the SW1/4 section 20, T. 76 S., R. 87 E., of the Copper River Meridian.|
Geologic descriptionBrooks (1902) described this prospect as a claim said to carry copper values. Nothing else is known about it. The rocks in the area are part of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996).
