MAS/MIL number 20760027.
Location: Placer mining has occurred on North Creek, a west tributary to Crooked Creek at several locations. The coordinates are near the midpoint of the creek at an elevation of about 3,750 feet, near the southeast corner of sec. 6, T. 22 N., R. 12 E., Seward Meridian. The location is accurate.
Geology: The rocks in the drainage of North Creek drains are volcanic and sedimentary rocks of the Lower Jurassic, Talkeetna Formation (Csejtey and others, 1978). The gold placers occurs in Tertiary(?) alluvial gravel . Fine gold also occurs in Quaternary glacial and glaciofluvial deposits in the vicinity, but not in mineable quantities (Cobb, 1973 [B 1374]). Intermittent, small-scale mining occurred from 1912 to at least 1961 ( Cobb, 1973).
Workings: Intermittent, small-scale mining occurred from 1912 to at least 1961 ( Cobb, 1973).
Age: Tertiary(?) and Quaternary placers.

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a)
