Tysdal (1978 [MF-880-A]) and Jansons and others (1984) located this occurrence in the same spot, but their descriptions do not match.
Location: The occurrence is located in the SW1/4 section 23, T. 5 N., R. 7 E., of the Seward Meridian. It is situated on or near the west shore of McClure Bay, just east of hill 1692. This is location 112 of Tysdal (1978 [MF-880-A]) and location S-96 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: There is much confusion in the literature about this occurrence. Tysdal (1978 [MF-880-A]) described it as a small iron-stained breccia zone in sandstone containing 100 ppm zinc. Jansons and others (1984) describe this occurrence as thin vuggy quartz veins about 1 inch wide containing pyrite and chalcopyrite in interbedded shale and graywacke of the Tertiary Orca Group. No workings exist.
Workings: Tydsal (1978 [MF-880-A]) reported 100 ppm zinc in iron-stained breccia.
Age: Tertiary or younger; the occurrence is in Orca Group rocks of Tertiary age.
Alteration: Iron staining.
