The Iron Creek is a iron and manganese 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 (Geology): Age = Post mid-Cretaceous, the age of metamorphism of the host schist and marble.
Comment (Reserve-Resource): Reserves = Shallit (1942; Mulligan and Hess, 1965, table 3) estimated that there are 12,000 long tons of limonitic material containing 20 to 40 percent iron and 20,000 long tons of limonitic material containing 10 to 20 percent iron.
Comment (Geology): Geologic Description = Limonitic rocks occur in a synform near the base of a marble unit (Herreid, 1970, figure 1). According to Mulligan and Hess (1965), samples of outcrop consist of finely crystalline marble with minor disseminated limonite and limonitic cavity fillings; sericitic schist with minor earthy and compacted limonite and accessory rutile is also present. Associated schist consists of chlorite, limonite, quartz, biotite, sericite, manganese oxides (pyrolusite?), and minor clay. There is an estimated resource of 12,000 long tons of material that contains 20 to 40 percent iron and 20,000 long tons of 10 to 20 percent iron (Shallit, 1942; Mulligan and Hess, 1965, table 3). Mulligan and Hess (1965) found no evidence of sulfides at this deposit, and samples collected by Herreid (1970) contained only as much as 220 ppm zinc.
Comment (Workings): Workings / Exploration = Some surface prospecting pits are probably present.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Mulligan and Hess, 1965
Comment (Deposit): Model Name = Iron oxide veins and replacement of marble and schist.
Comment (Geology): Age = Host rock is Pre Campanian - Post Barremian.
