|Location and accuracy||This occurrence is located an an elevation of about 3,000 ft 1 1/2 miles west of Tobin Pass and 4 miles east-southeast of the mouth of Tobin Creek (sec. 24, T. 31 N., R. 4 W., of the Fairbanks Meridian). The location is accurate within a 1-mile radius.|
Geologic descriptionThe only information available on this prospect is that 34 lode claims were staked in 1973 (DeYoung, 1978). Its location just south of the Chandalar District gold lodes makes it of some interest.
|Geologic map unit||(-148.342727737647, 67.4996126314919)|
|Mineral deposit model||Low-sulfide Au-quartz veins? (Cox and Singer, 1986; model 36a?).|
|Mineral deposit model number||36a?|
|Age of mineralization||Middle Cretaceous(?) based on arguments by Dillon (1982) that the age of emplacement of the gold-bearing quartz veins of the Koyukuk and Chandalar districts was between the Neocomian metamorphism of the Devonian host rocks and their erosional unroofing and cooling in Albian time.|
|Indication of production||None|
