The property was patented in 1912, and the workings have been filled in. Private homes have been built on the site.
Location: The prospect is located in near the west edge of section 10, T. 1 S., R. 1 W., of the Seward Meridian. The workings are located within the city limits of Seward near the western side. This is location 90b of Cobb and Tysdal (1980) and location S-198 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: The prospect consists of several quartz veins that follow jointing in massive sandstone. The host rock is slate and sandstone of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The main working is a 265-foot adit with a winze, at an elevation of 100 feet. One 3- to 14-inch-wide vein strikes N55W and dips 81NE at the portal. A second vein is 10 inches wide; it is located 75 feet north of the portal, and it strikes N57W and dips 85N. A third vein, located south of the portal, strikes N75W and dips 85N; this vein is 8 to 14 inches wide and is traceable along the surface for 200 feet (Grant and Higgins, 1909). Metallic minerals in the veins include arsenopyrite, chalcopyrite, galena, pyrite, and sphalerite; gold is also present (Martin and others, 1915). In addition to the 265-foot adit, there is a 12-foot shaft nearby, as well as two other short adits (Martin and others, 1915). No assay results are reported in the literature.
Workings: The workings included three adits and a shaft. The upper 265-foot adit with a small winze was at 100 feet elevation. The 12-foot shaft was nearby, and two other short adits were below 100 feet elevation (Martin and others, 1915). All of these workings have been filled in. No assay results are reported in the literature.
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.
