Location and accuracy The Lucky Strike prospect is poorly known and can be located no more closely than somewhere high on the ridge between Grace Harbor and Gooseneck Harbor in the center of Dall Island. The location may be anywhere within a mile or more of the SE1/4 section 30, T. 80 S., R. 83 E. Maas and others (1991) were unable to locate the prospect in the dense vegetation and there has apparently been little if any work on it since 1916.

Geologic setting

Geologic description

The Lucky Strike prospect is near a regional-scale normal fault that separates pre-Ordovician marble and metamorphosed dacitic rocks to the west from pre-Ordovician, metamorphosed dacitic rocks to the east (Gehrels, 1991). As described by Chapin in 1918, the prospect is in a shear zone that contains chalcopyrite, pyrite, and much limonite. The host rocks are cut by quartz veinlets that carry pods of chalcopyrite. Chapin notes little development and there has apparently been little or no work on the property since 1918. Maas and others (1991) were unable to locate this prospect in the thick vegetation.

Age of mineralization Unknown, other than that it is younger than the pre-Ordovician host rocks.
Alteration of deposit Oxidization of pyrite.

Production and reserves

Workings or exploration Probably little if any development; there apparently has been little or no work on this prospect since at least 1918. Bufvers (1967) indicates that it was discovered by Aaron Shellhouse.
Indication of production None

Additional comments

The surface and subsurface rights to the land in the vicinity have been conveyed to the Sealaska Corporation or are under application.
