|Location and accuracy||The occurrence is located on the northeast side of the terminus of the Wolverine Glacier at an elevation of about 1,400 feet. It is in the NE1/4 section 10, T. 3 N., R. 3 E., of the Seward Meridian. This is location S-185 of Jansons and others (1984). This location is accurate to 1,500 feet.|
Geologic descriptionThe occurrence consists of iron-stained quartz-calcite veins that recement fractured, tabular felsic dikes. The dikes strike N20-40E and dip vertically. The dikes are part of a north-northeast-trending belt of dikes that extends at least 25 miles to Blackstone Bay (Hoekzema and Sherman, 1983). The dikes intrude interbedded volcanic and sedimentary rocks of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The age of the dikes is unknown. Sulfide mineralization consists of chalcopyrite, pyrrhotite, and pyrite. The size of the veins is not reported.
|Geologic map unit||(-148.900995784839, 60.371003155189)|
|Mineral deposit model||Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)|
|Mineral deposit model number||36a|
|Age of mineralization||Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.|
|Workings or exploration||No workings or improvements are reported in the literature. The U.S. Bureau of Mines collected one grab sample that assayed a trace of gold and 0.07 ounce of silver per ton (Jansons and others, 1984).|
|Indication of production||None|
