|Location and accuracy||The occurrence is located in the NE1/4 section 30, T. 5 N., R. 2 E., of the Seward Meridian at an elevation of about 5,000 feet. It is located about 2 miles northeast of the head of Grant Lake and less than a quarter-mile east of a small unnamed glacier. This location 68 of Tysdal (1978 [MF-880-A]) and location S-230 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe mineralization consists of a reddish-brown iron-stained zone more that 30 feet wide. The host rock in this area is mapped as Valdez Group of Late Cretaceous age (Nelson and others, 1984). A single grab sample contained 3,000 ppm manganese, 70 ppm chromium, and 60 ppm zinc (Tysdal, 1978 [MF-880-A]).
