|Location and accuracy||The Green Mountain prospect is located in the SW1/4SW1/4 sec. 26, T. 2 N., R. 1 E., Fairbanks Meridian. This deposit is on the west side of Rose Creek, about 1,000 feet west of the mouth of Evening Star Creek. It is about 4.1 miles west-southwest of the top of Gilmore Dome. The prospect is included in locality 30 of Cobb (1972 [MF 410]).|
Geologic descriptionA small open cut exposes a 15-foot-wide quartz vein (Chapin, 1914, B 592-J, p. 321-355). An adit driven to crosscut the vein intersected a brecciated mass of schist with small quartz veins; free gold was panned here from crushed rock (Chapin, 1914, B 592-J, p. 321-355). This prospect lies on the western edge of a Cretaceous granite that intrudes two units of the Fairbanks Schist that are composed of (1) quartz-muscovite schist, quartzite, and chlorite-quartz schist, and (2) amphibolite, magnetite-rich biotite schist, quartz schist, and marble (Newberry and others, 1996).
