Location and accuracy | The Alaska Rand prospect is at an elevation of approximately 100 feet on an unnamed, south-flowing creek that empties into the west head of Hawk Inlet. It is 2.5 miles east-southeast of Snowy Mountain and 2 miles west of Young Bay, in the SW1/4SE1/4 section 34, T. 42 S., R. 65 E. of the Copper River Meridian. The location is accurate within 1/4 mile. |
Geologic descriptionThe Alaska Rand prospect is in folded and altered, phyllite and greenschist that generally strike N. 25 W. and dip 60 W (Roehm, 1937). The deposit consists of quartz lenses in the schist (Roehm, 1937). Three quartz lenses, 1- to 6-feet- thick can be traced for up to 90 feet. The quartz is white and clear in alternating bands, and contains sparse pyrite and arsenopyrite, with some calcite (Wells and others, 1986). Gold was discovered at this prospect in 1922 (Roehm, 1937). Trenches and a 25-foot crosscut were started in 1923 and a 400-foot road was built to the beach. Channel samples contain up to 2 ounces of gold per ton (Roehm, 1937). The rocks in the general area are mainly Ordovician and Devonian to Triassic, clastic units , mafic-intermediate volcanic rocks, and subordinate limestone. The bedded rocks are intruded and locally metamorphosed by Cretaceous granodiorite (Gehrels and Berg, 1994). | |
