Dog Hole

The Dog Hole is a silver, gold, lead, 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.

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 (Workings): Workings / Exploration = Prospect has been explored by a 6-foot adit. Samples of the deposit collected by the U.S. Bureau of Mines in 1992 or 1993 (Maas and others, 1995, p. 244) contain up to 1.3 ppm Ag, 30.1 ppm Ag, 0.84 % Pb, and 2.17% Zn.

Comment (Reference): Primary Reference = Maas and others, 1995

Comment (Geology): Age = Maas and others (1995, p. 235, 244) describe the deposit as sulfide-bearing silicified Hazelton volcanic rock and argillite. The sulfides are pyrite, galena, and sphalerite. Lead-isotope studies of galena from the prospect indicate that the deposit is Jurassic in age, contemporaneous, at least in part, with island-arc volcanism in Hazelton time (Alldrick, 1993).

Comment (Geology): Geologic Description = The country rocks in the area of the Dog Hole prospect are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which is underlain and locally intruded by the Triassic Texas Creek Granodiorite; and the Eocene Hyder Quartz Monzonite, which intrudes the Hazelton and Texas Creek rocks (Smith, 1977; Koch, 1996). Maas and others (1995, p. 235, 244) describe the deposit as sulfide-bearing silicified[?] Hazelton volcanic rock and argillite. The sulfides are pyrite, galena, and sphalerite. Lead-isotope studies of galena from the prospect indicate that the deposit is Jurassic in age, contemporaneous, at least in part, with island-arc volcanism in Hazelton time (Alldrick, 1993). Samples of the deposit collected by the U.S. Bureau of Mines in 1992 or 1993 (Maas and others, 1995, p. 244) contain up to 1.3 ppm Ag, 30.1 ppm Ag, 0.84 % Pb, and 2.17% Zn.

Comment (Deposit): Model Name = Polymetallic veins
