Steiner

The Steiner is a 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.

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 (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Uncertain; 105-foot shaft with 220 feet of drifting reported by Cathcart (1922), but Mertie (1918 [B 662-I, p. 427]) reported a 135-foot shaft with 100 feet of drifting at a nearby location, if not this one.

Comment (Geology): Geologic Description = Cathcart (1922, p. 256) reports that a 105-foot shaft was sunk on a 5- to10- foot-wide, east-striking, quartz-feldspar vein. The vein was followed 60 feet in the shaft and lost. Values of 7 dollars per ton (about 0.35 ounce of gold per ton) were reported but not confirmed. It seems questionable whether Cathcart actually visited this prospect. The shaft dump on the east side of Penny River is at least partly in graphitic quartz schist, reportedly one of the rock types at the Steiner prospect. Mertie (1918 [B 662-I, p. 427]) visited this mine, but it was not open at the time. He reported the shaft to be 135 feet deep with 100 feet of drift. Mertie (1918) also reported the rock on the dump as iron-stained pyritized schist, which agrees with C.C. Hawley's inspection of the site in section 35 east of Penny River.

Comment (Reference): Primary Reference = Mertie, 1918

Comment (Deposit): Model Name = Low-sulfide Au-quartz vein (Cox and Singer, 1986; model 36a).

Comment (Geology): Age = Mid-Cretaceous or younger; vein crosscuts metamorphic rocks.
