Identification information

Deposit ID	10308543
Record type	Site
Current site name	Victor

Geographic coordinates

Geographic coordinates:	-149.38334, 67.62971 (WGS84)
Relative position	The Victor prospect is at an elevation of about 4,300 feet in the hills between Big Spruce Creek and Mathews River. It is approximately 8 miles north-northeast of the north end of Bob Johnson Lake (formerly Big Lake) and 4 miles northwest of the confluence of Big Spruce Creek and Bettles River (NW1/4 sec. 5, T. 32 N., R. 8 W. and SE1/4 sec. 32, T. 33 N., R. 8 W., of the Fairbanks Meridian). The Victor prospect was part of a large claim group that encompassed the Venus (CH065) and Eva (CH063) prospects, and the Victor prospect is approximately 1 1/2 miles west of the Venus prospect. The location is accurate within a 1/2-mile radius.

Comments on the geologic information

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.
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)

District name	Koyukuk

Comments on the reserve resource information

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.

Comments on the workings information

Workings / Exploration = At least 23 claims staked from 1967 to 1970.

General comments

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