Location: The McGrath occurrence is located in the SE1/4SE1/4 sec. 18, T. 1 N., R. 1 E., Fairbanks Meridian. This low-grade gold occurrence is about 0.5 mile east of the intersection of McGrath Road and the Old Steese Highway in a residential area. The occurrence is locality 25 of Cobb (1972 [MF 410]).
Geology: This occurrence consists of a 7-inch-wide, low-grade, gold-quartz vein in schist (Chapman and Foster, 1969, p. D16; Saunders, 1963 [ATDM PE 58-13]). Stein (1957) reported that the vein strikes N80E and dips 60S. The upper portion of the vein is well oxidized; it grades into fresh sulfides at depth. The chief mineralization is jamesonite with associated gold and silver (Stein, 1957). A shaft driven to the 80-foot level soon after the vein was discovered caved due to poor bracing. Since then most of the prospecting has been confined to surface work and short shafts (Stein, 1957). There is no record of production.
Workings: A shaft driven to the 80-foot level soon after the vein was discovered caved in due to poor bracing. Since then, most of the prospecting has been confined to surface work and short shafts (Stein, 1957).
