Lucky Find Prospect, Karta River Wilderness, Prince of Wales Island, Ketchikan District, Prince of Wales-Outer Ketchikan Borough, Alaska, USA

Latitude: 55°31'42"N
Longitude: 132°40'58"W
This prospect is in the Karta River Wilderness Area, which is closed to exploration and mining.
Location: The only published location for the Lucky Find prospect is on a small map by Wright and Wright (1908) that cannot be reconciled with the modern USGS 1:63,360-scale topographic map. For this record, the location is about 0.3 mile west-southwest of Granite Mountain and about 0.2 mile northwest of the center of section 20, T. 73 S., R. 84 E. The location is probably accurate to within 0.5 mile.
Geology: The rocks in the vicinity of the Lucky Find 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) describe this prospect as a 1-foot-thick quartz vein between a diabase dike and granite. The vein also contains calcite and possibly siderite, as well as chalcopyrite and pyrite. The prospect has been explored by a 50-foot tunnel.
Workings: Prospected by a 50 foot tunnel.
Age: Unknown, other than that the vein is in Devonian granitic rocks.

Commodities (Major) - Au?, Cu
Development Status: None
Deposit Model: Gold?-quartz vein, with chalcopyrite.
