Michigan Creek

The Michigan 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 (Reference): Primary Reference = Thomas, 1970

Comment (Workings): Workings / Exploration = The first discovery of placer gold in the Goodpaster region was on Michigan Creek in 1915 (Thomas, 1970). However, deposits were low grade, and mining activities soon ended. Before World War I, reports from placer mining deposits in the region were vague (Cobb, 1973; B 1374). Therefore, it is unclear where mining activities on Michigan Creek took place.

Comment (Geology): Geologic Description = The area is characterized by rounded hills and flat-topped ridges (Thomas, 1970). According to Weber and others (1978) the bedrock in the area is composed of gneiss, quartzite, augen gneiss, and some amphibole schist. The gravels on Michigan Creek are 12 to 25 feet thick and contain coarse gold (Brooks, 1916). Eberlein and others (1977) reported that a 1/2 ounce nugget was found on Michigan Creek. Stream-sediment and rock-chip samples collected from unknown locations in the creek drainage contain up to 10 ppb Au (North Star Exploration Inc., unpublished data, 1998).? the first discovery of placer gold in the Goodpaster region was on Michigan Creek in 1915 (Thomas, 1970). However, deposits were low grade, and mining activities soon ended. Before World War I, reports of placer mining deposits in the region were vague (Cobb, 1973; B 1374). Therefore, it is unclear where mining activities on Michigan Creek took place. Cobb (1973; B 1374) reports insignificant placer gold production from the Goodpaster region. It is unclear how much gold was produced from Michigan Creek.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Quaternary

Comment (Production): Production Notes = Cobb (1973; B 1374) reports insignificant placer gold production from the Goodpaster region. It is unclear how much gold was produced from Michigan Creek.

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
