|Location and accuracy||Cobb (1972, MF-413), loc. 30; NE1/4NE1/4 sec. 2, T. 2 N., R. 1 E., of the Fairbanks Meridian. The mine is on the south side of the west fork of Skoogy Gulch; it is at an elevation of 1,780 feet, about 7.5 miles northeast of Fox along the Steese Highway. The North Star Extension claim covers part of the old Central Star shaft. Accuracy is within 1,000 feet.|
Geologic descriptionGold occurs in a 20-foot-wide quartz porphyry dike that strikes N 30 W and dips 45 SW. This dike was exposed by a tunnel driven 50 feet through schist. The dump material on the Central Star shaft is composed mainly of schist but contains some fragments of quartz porphyry (Hill, 1933, p. 118). In 1909, this shaft was 65 feet deep (Prindle, 1910).

|Mineral deposit model||Gold-bearing quartz porphyry dike.|
|Workings or exploration||This property was developed by tunnels and shafts. In 1909 the Central Star shaft was 65 feet deep with 200 feet of tunnel (Prindle, 1910).|
|Indication of production||Yes; small|
|Production notes||In 1916, some ore was milled on the ground in a home-made 1-stamp mill driven by a 6-horsepower gasoline engine (Hill, 1933, p. 118).|
