|Location and accuracy||This prospect is at an elevation of about 3350 feet in a minor saddle on the ridge between Yellow and Rainy Creeks. It is in the north part of the SE1/4 SE1/4 section 3, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 300 feet. The prospect corresponds to number 210 of Hawley and Associates (1978), 43 of Bundtzen, Smith, Tosdal (1976), 49 of Bundtzen (1981), and 62 of Thornsberry, McKee, and Salisbury (1984).|
The country rocks in the area of this prospect are complexly faulted, lower Paleozoic Spruce Creek phyllite and semischist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2).The deposit is a sparsely mineralized, fault-controlled, quartz-calcite vein that strikes N 20-40 W and is nearly vertical. The vein is 5 to 6 feet thick and contains pyrite and arsenopyrite. Assays show up to 100 ppm molybdenum and a trace of gold.
