Location: The Late prospect is at an elevation of about 2,500 feet, about 1.5 miles northeast of the head of Lisianski Inlet. The prospect is 0.4 mile west-southwest of the center of sec. 26, T. 46 S., R. 58 E. It is MAS no. 0021140191 (U.S. Bureau of Land Management, 2002). The location is accurate within 0.5 mile.
Geology: Loney and others (1975) and Johnson and Karl (1985) map the rocks in the area of this prospect as Paleozoic volcanic and sedimentary rocks that are intruded by, or are roof pendants in, a Cretaceous or Jurassic batholith of granodiorite, diorite, gabbro, and tonalite. The strata are thermally metamorphosed to hornfels, granofels, schist, gneiss, and marble. The rocks are cut by numerous high-angle faults of varying, but mainly northwest, strike. The most prominent of these is the regional-scale Peril Strait Fault that extends along Lisianski Inlet just southwest of the prospect. The only published information about the prospect is that it has been staked for an unspecified commodity (U.S. Bureau of Land Management, 2002).
Development Status: Undetermined.
