|Location and accuracy||Placer claims on Nicolie Creek extend upstream from its mouth for about 2 miles. They are in the S1/2 sec. 11, T. 24 N., R. 12 E., Seward Meridian. The location is accurate to within 1/2 mile.|
Geologic descriptionNicolie Creek drains an area of sandstone, siltstone, and claystone (Csejtey and others, 1978). The surrounding hills are Tertiary fluviatile conglomerate. The creek is 4 miles long and has an average gradient of 100 feet per mile. Placer claims were staked in 1973 and 1982 (Kurtak and others, 1992). The gold occurs in the alluvial gravel deposits. Stream-sediment samples collected by the U.S. Bureau of Mines contain 7 parts per million gold and 130 parts per billion platinum (Balen, 1990). Gold fineness ranges from 388 to 643.
