The Stoney Vein is a silver, lead, copper, and 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.

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 = Copper (native)
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)
Comment (Geology): Geologic Description = Part of the Yentna trend of Late Cretaceous/early Tertiary composite plutons (Tcp) described by Reed and Nelson (1980), the Mount Estelle pluton (Tme, Reed and Elliott, 1970) extends from Timber Creek on the south to the Portage Creek area in the north. At this site in the central part of the pluton, a biotite-hornblende-quartz monzonite intrudes Mesozoic marine sedimentary rocks (KJs) of the Kahiltna terrane. ? Two veins follow dilatational zones within the pluton along its west side (Cominco American Incorporated, unpublished reports, 1986-1987). The Main Stoney vein is steeply dipping structure that is mapped as more than 3 miles long, varies in measured width from 14 feet to 60 feet and has a vertical relief of at least 1000 feet. The mineralogy consists of alternating sulfide-quartz -carbonate vein material and altered intrusive material. The mineralogy consists of quartz-calcite-dolomite-siderite-tourmaline-pyrrhotite-chalcopyrite- arsenopyrite-pyrite-stibnite +/- graphite, sphalerite and galena. The North Stoney vein is a sub-parallel feature just west of the northern end of the Main Stoney vein. This vein is 35 feet at it's widest and has similar mineralogy to the Main Stoney vein. A third vein is located one mile to the west.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Possibly related to the Tertiary/Cretaneous pluton that is the host rock
Comment (Geology): Age = Host rock is Tertiary - Cretaceous.
Comment (Workings): Workings / Exploration = Exploration included prospecting, rock chip geochemical sampling, and mapping. Technical climbers were employed to map and sample the steep terrain.
Comment (Reference): Primary Reference = Reed and Elliott, 1970
