| Location and accuracy | This prospect is at an elevation of about 1,000 feet on the west slope of Twin Mountains Creek valley, due west of the central part of Twin Mountain Creek. The prospect is in the NW1/4NW 1/4 section 33, T. 9 S., R. 34 W., Kateel River Meridian. The vein at this prospect extends westward into the Nome C-2 quadrangle. The location is accurate within about a half mile. |
Geologic descriptionThis prospect is on a simple quartz vein, as much as 3 feet thick and 600 feet long, that strikes northwest and dips steeply. It cuts across the schistosity of the host micaceous calc-schist. The vein contains as much as several percent of stibnite and galena. It is within a major geochemical soil anomaly characterized by gold, arsenic, and lead, that extends from the Rodine prospect (NM165) to Bangor Creek north of the Twin Mountain prospect (NM186). | |
