The Katy-O is a zinc 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 = Andrews and Rishel, 1982
Comment (Deposit): Model Name = Southeast Missouri Pb-Zn (Cox and Singer, 1986; model no. 32a) or Mississippi Valley Type
Comment (Geology): Geologic Description = The Katy-O occurrence is a poorly exposed gossan in a small area of unit 'Dlr' of Andrews and Rishel (1982); it is probably equivalent to the lower Whirlwind Creek Formation of Dutro and Patton (1982). Host unit is inferred to be Lower Devonian, based on fossils. The age of the mineralization is unknown. Gossan in float contains 1 percent zinc (Andrews and Rishel, 1982).
Comment (Deposit): Other Comments = See Lynn-Marie (MD042) Mississippi Valley Type occurrence. The Katy-O occurrence is on land selected or conveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
Comment (Geology): Ore Material = Zinc-bearing gossan
Comment (Geology): Age = Host unit is inferred to be Lower Devonian, based on fossils. The age of the mineralization is unknown.
Comment (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = The Katy-O occurrence was discovered by WGM Inc. and Patino Ltd. during exploration for base metals in the late 1970s on lands selected by Doyon Ltd. (Andrews and Rishel, 1982). Gossan in float contains 1 percent zinc.
