Victor

The Victor is a 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 (Reference): Primary Reference = Nicholson, 1990

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 (Exploration): Status = Inactive

Comment (Reserve-Resource): Reserves = Nicholson (1990) estimated that skarn pods at Victor and Eva contain 50,000 tons of 2 percent Cu. She notes that comparisons with tonnages of other porphyry copper-related skarns and the presence of extensive calcareous rocks in the area suggest appreciable undiscovered skarn mineralization. Young and others (1997) give a range of 74,000 tons to 4.56 million tons as an aggregate resource figure.

Comment (Deposit): Other Comments = See also: Venus (CH065), Eva (CH063), and Evelyn Lee (CH059) prospects. Most of the publications describing this area provide a combined description of the Venus-Victor-Eva prospects. The land (and presumably the original claims) have been acquired by Doyon, Limited via its Alaska Native Claims Settlement Act selections. Bornite and chalcopyrite reportedly have been sighted in cliffs along Mathews River (DeYoung, 1978, loc. 72). That mineralization is possibly on the Victor and/or Eva prospects.

Comment (Workings): Workings / Exploration = At least 23 claims staked from 1967 to 1970.

Comment (Geology): Geologic Description = The Victor and Venus (CH065) prospects both are in a terrane of altered Devonian(?) meta-granodiorite and contact-related garnet-pyroxene skarns developed in adjacent marbles and calc-schists. Alteration of the meta-granodiorite at Venus appears to be more intense than at Victor, which is characterized by propylitic and sericitic, but not potassic, alteration (Nicholson, 1990). Mineralization at the Victor prospect apparently is more prevalent in the skarns than in the meta-igneous rocks (Nicholson, 1990). Minerals in the skarns are retrograded and have been sketchily described as garnet, clinopyroxene, actinolite, epidote, calcite, quartz, chlorite, chalcopyrite, plus or minus bornite?, and pyrite (Nicholson, 1990). A hand specimen from the Victor prospect, described in Newberry and others (1986), yielded values of 1.1 percent Cu, 5.5 ppm Ag, less than 0.14 ppm Au, and negligible Pb and Zn. Young and others (1997) reported that hundreds of meters (presumably in drill intercepts) with grades of 0.1 to 0.6 percent Cu have been found on the property, with some values as high as 5.5 percent Cu, 150 ppm Mo, and 0.41 ppm Au. Nicholson (1990) noted that some workers have characterized the mineralization in the Big Spruce Creek area as volcanogenic in origin. Although Young and others (1997) discuss the Victor prospect as a porphyry copper deposit, their comments may more broadly encompass the Victor-Venus-Eva prospects.

Comment (Deposit): Model Name = Porphyry Cu, skarn-related deposits(?) (Cox and Singer, 1986; model 18a)
