This prospect is now in the Karta River Wilderness Area which is closed to exploration and mining.
Location: As located by Maas and others (1991), the Lucky Jim prospect is at an elevation of about 2,900 feet, 0.5 mile south of Granite Mountain and about 0.3 mile south-southeast of the center of section 20, T. 73 S., R. 84 E.
Geology: The rocks in the vicinity of the Lucky Jim prospect are part of a large granodiorite-quartz diorite stock (Sainsbury, 1961; Eberlein and others, 1983; Brew, 1996). Early workers considered the stock to be Mesozoic or Cretaceous; however, recent radiometric dating indicates that it is Devonian (S.M. Karl, oral communication, 2003). Wright and Wright (1908) described the deposit as an auriferous quartz vein that strikes N25W and dips 40NE in granitic rock. The vein also contains pyrite, galena, and secondary copper carbonates. Maas and others (1991) collected two samples that averaged 28.1 parts per million (ppm) silver and 0.96 ppm lead. They also cited an unconfirmed report of a small vein of galena in highly deformed marble. That report contradicts Wright and Wright (1908), who described the prospect as a vein in granitic rock. Maas and others (1995) do not mention marble in their table of deposits in the Hollis area. At the location visited by Maas and others (1991), the workings consisted of a 20-foot shaft and a short adit below the shaft.
Workings: The only workings are a 20-foot shaft and a short adit below the shaft.
Age: Unknown, other than that the vein is in Devonian granitic rocks.

Commodities (Major) - Ag, Au, Pb
Development Status: None
Deposit Model: Unclear; there are contradictory descriptions of the deposit and its host rocks.
