NOTE:The subsurface rights to the land in the vicinity of this prospect are held by the Sealaska Corporation.
Location: This occurrence is at an elevation of about 1,100 feet about 1.1 mile east-northeast of Bautista Peak. It is about 0.3 mile southeast of the center of section 28, T. 74 S., R. 80 E.
Geology: This prospect is associated with a small Cretaceous granitic stock that makes up the center of San Juan Bautista island. The stock intrudes Devonian graywacke, mudstone, and siltstone of the Port Refugio Formation, which crops out along the entire coastline of the island (Eberlein and others, 1983; Brew, 1996). The occurrence consists of minor pyrite and chalcopyrite disseminated in diorite (Clark and others, 1970 [OF 418]).
Age: Probably related to the emplacment of Cretaceous diorite.
