Cripple Creek

The Cripple Creek is a lead, zinc, silver, and copper 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 = Property was developed in 1920's by a 45-foot adit and a short crosscut.

Comment (Deposit): Model Name = Polymetallic veins

Comment (Deposit): Other Comments = Property was probably originally staked in early 1920's. Taken over by Brigadier Mining Company sometime before 1929 (Buddington, 1929, p. 83).

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = The country rocks in the area of this prospect are the Triassic Texas Creek Granodiorite, which underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Eocene Boundary Granodiorite, which intrudes the Texas Creek and Hazelton rocks; and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith 1973, 1977; Koch, 1996).? There appear to be two main types of deposits (Buddington, 1925, p. 74; 1929. p. 83-84). (1) A quartz fissure vein up to 8 feet thick in the footwall of a 10-15-foot thick sheeted shear zone in granodiorite. The vein contains considerable galena and smaller amounts of pyrite, chalcopyrite, sphalerite, and tetrahedrite, and was explored by a 45-foot adit and a short crosscut. (2) Fissured and brecciated zones comprising sulfide-bearing quartz veinlets and sulfide-impregnated granodiorite. Pyrite is the principal sulfide in these zones, accompanied by a little galena and sphalerite.
