Unnamed Prospect (ARDF - FB035; head of Eva Creek), Fairbanks District, Fairbanks North Star Borough, Alaska, USA
Location: This prospect is near the head of Eva Creek at an elevation of about 1,600 feet in the SE1/4 NE1/4 sec. 31, T. 1 N., R. 2 W., Fairbanks Meridian. The prospect is about 1.7 miles north of the town of Ester.
Geology: A 60-foot shaft was sunk on a quartz vein carrying considerable stibnite and disseminated sulfides (Smith, 1913 [B 525, p. 208]). The quartz is fine-grained, granular, and has a grayish color; visible gold was reported to be fairly common. Bedrock in the area was mapped as biotite schist of the Muskox sequence by Newberry and others (1996). Thomas (1947) reported that approximately 1,500 feet of surface trenching has been done on the property but that no veins or mineralized zones were discovered. They did discover four flat-lying faults in mica schist. These faults were filled with white talc gouge. All underground workings on the property are caved and inaccessible.
Workings: A 60-foot shaft was sunk on a quartz vein (Smith, 1913 [B 525, p. 208]).
Production: About 1,000 tons of gold ore was mined from this property (Thomas, 1947).
