This is location 265 of Tysdal (1978 [MF-880-A]) and location S-8 of Jansons and others (1984). The location is accurate to within a quarter of a mile.
Geology: The occurrence consists of a limonite-stained gossan that contains pyrite and chalcopyrite. The gossan zone is 4 feet wide and more than 45 feet long (Tysdal, 1978 [MF-880-A]). Tysdal (1978 [MF-880-A]) reported a semiquantitive spectrographic analysis of the gossan is 700 ppm copper, and 500 ppm zinc. The host rock is altered slate and sandstone of the Orca Group of early Teriary age (Nelson and others, 1985).
Workings: No workings are reported.
Age: Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.
Alteration: The host rock is altered, but the type of alternation is not reported (Tysdal, 1978 [MF-880-A]).
