|Location and accuracy||Cobb (1972, MF-413), loc. 61; SW1/4NE1/4 sec. 7, T. 7 N., R. 10 W., of the Fairbanks Meridian. The coordinates given are for the mine marked on the Livengood (B-6) quadrangle along Gunnison Creek near its confluence with Troublesome Creek.|
Geologic descriptionPlacer mining was reported in 1904 and 1918 in stream placers near the mouth of the creek; mining may have been carried on in a few other years (Cobb, 1976; OFR 76-633, p. 84). A concentrate sample contained magnetite, ilmenite, picotite, zircon, scheelite, garnet, gold, pyrite, rutile and other nonmetallic minerals (Waters, 1934). Gunnison Creek drains a contact zone between granitic rock and quartzite, phyllite, slate, and chert (Eberlein and others, 1977, p. 65).
