The Pasco Creek is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Production): Production Notes = It is unclear how much gold was produced from Pasco Creek.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Quaternary
Comment (Workings): Workings / Exploration = Placer gold was first discovered in the Salcha River area in 1905. Prospecting initially occurred on Butte Creek (BD006) and soon extended to nearby Caribou Creek (BD009), and Gold Creek (BD015) and associated tributaries. Live water and thawed ground presented the biggest obstacles during prospecting (Prindle, 1906; B 284). The first claims on Pasco Creek were staked in 1954 (Cobb and Eberlein, 1980). Subsequently, there have been active claims in 1976, 1977, and 1980 (Eberlein and others, 1977). The Alaska Division of Mining Kardex file system records active claims on Pasco Creek as recent as 1986. There is evidence of surficial mining operations, but the period of activity is unknown (Eberlein and others, 1977).
Comment (Geology): Geologic Description = The bedrock in the region is primarily schist, gneiss, some granite, and minor amounts of serpentinite and limestone. The intrusive bodies in the area range in composition from granodiorite to quartz monzonite with Cretaceous to Tertiary K-Ar ages (Weber and others, 1978). The gravels in the region average 18 to 20 feet in thickness and contain a variety of schist, gneiss, granite, and vein quartz (Prindle, 1906). Brooks (1908) reported the fineness of the gold to be higher than that mined in the Richardson district. ? Placer gold was first discovered in the Salcha River area in 1905.
