The Gayle is a copper, lead, silver, and 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.

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 (Commodity): Ore Material = argentiferous galena
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The Gayle prospect is one of at least two Pb-Zn-Ag plus or minus Cu prospects near this site. Descriptive information specific to the property is sparse. Brosgi and Reiser (1964) described the prospect as chalcopyrite( ?) and/or malachite-azurite stains near the top of the Skajit Limestone, while Grybeck (1977) reported that sphalerite and galena (with silver values) on the Gayle and Bob prospects occur in small veinlets and stockworks in altered limestone and marble. Newberry and others (1997) classify the Gayle prospect as a calcic Zn-Pb skarn and replacement body. These Zn-Pb skarns are described by Newberry and others (1986) as distal to Devonian(?) porphyry Cu-Mo systems associated with the Horace Mountain plutons in the Chandalar copper belt. The bedrock near the prospect is mapped as Devonian Hunt Fork Shale near its contact with Skajit Limestone. Intercalated diorite sills and andesitic flows(?) are also present in the section.
Comment (Deposit): Other Comments = See also: Bob (CH089) "&" Bibban (CH090). ? Brosgi and Reiser (1972, p. 7, 11), reported analytical results of 1 to 3 ppm Ag, 700 ppm Pb, and 6.5 ppm Au from a rock sample probably collected from the Gayle prospect.? Alaska Kardex Nos. 031-61C and 58B (Kardex is a card file mining claim information system located at the State of Alaska DNR Public Information Center in Fairbanks).
Comment (Deposit): Model Name = Zn-Pb skarn deposits(?) (Cox and Singer, 1986; model 18c)
Comment (Geology): Age = Devonian, based on reported Early Devonian Pb/Pb zircon ages from the associated Baby Creek batholith and Horace Mountain plutons (Dillon and others, 1996).
Comment (Reference): Primary Reference = Newberry and others, 1997
Comment (Commodity): Ore Material = copper sulfides and/or malachite
Comment (Workings): Workings / Exploration = Claims staked in 1972 and 1973.
