Location and accuracy The prospect is located in the SE1/4 section 9, T. 1 S., R. 1 W., of the Seward Meridian. It is in the south end of the town of Seward, near the aqueduct outfall. This is location 90a Cobb and Tysdal (1980) and location S-197 and of Jansons and others (1984). This location is accurate to within 300 feet.

Geologic setting

Geologic description

The prospect consists of four adits driven on several quartz-calcite veins within a N50E-striking shear zone. The host rock is slate and sandstone of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]). Adits were driven at elevations of 10, 70, 120, and 220 feet. The 70-foot-level adit was 100 feet long, and the 120-foot-level adit was 15 feet long. The veins had a maximum width of 3 feet and generally followed jointing. Metallic minerals include arsenopyrite, chalcopyrite, galena, pyrite, and sphalerite; gold is also present (Martin and others, 1915).

Production and reserves

Workings or exploration Workings consist of four adits that occur at elevations of 10, 70, 120, and 220 feet. The 70-foot-level adit has a 10-foot-long winze. The lowest adit is 100 feet long, and the 120-foot-level adit is 15 feet long (Martin and others, 1915). No assay results reported are reported in the literature.
Indication of production None

Additional comments

The workings have been closed and reclaimed by the City of Seward.
