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.

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property.

Comments

Comment (General): "Magnetite Products Corp. (now Plicoflex, Inc.) formerly mined magnetite from an open-pit. In 1962, the company moved its operations to Iron Mountain." Bull. 50, p. 108.

Comment (Identification): Mine shown as Iron on Geological Survey of Wyoming's "Mineas and Minerals Map of Wyoming" in the equivalent of Sec. 2 appears to be an error based on the incorrect section in Bull. 50. ABW could find no indication of a mine in Sec. 2. The location given as sec. 21 in IC-8315 is assumed to be the correct location.

Comment (Reserve-Resource): RESERVES CALCULATED FROM AVERAGE DIMENSIONS ASSUMING AVERAGE AND DEPTH TO BE 1/2 OF MAXIMUM (REF 1) - PRODUCTION TO OF 150000 LONG TONS WAS SUBTRACTED TO ARRIVE AT RESERV

Comment (Location): E2 of sec. 21 (IC-8315, p. 15). Supposed location in Sec. 2 in Bull. 50, p. 108, appears to be a typo. There is a prospect on MF-119 in Sec. 21. There are no prospects in Sec. 2. Sec. 2 is mapped as hornblende syenite, not anorthosite, and therefore is unlikely to host this deposit, based on the two brief deposit descriptions not mentioning syenite. The mines and minerals map of Wyoming (1970) appears to propagate this error. Nor is there any indication of surface or road disturbances in Sec. 2.
