Location: This occurrence is on a northeast-trending ridge between Ruby Creek and Moose Creek. The occurrences is at an elevation of about 1,650 feet, about 0.7 mile southeast of hill 1949, and about 0.5 mile north-northwest of the center of section 10, T. 26 N., R. 45 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is a zone of quartz-calcite veins in an altered silica-carbonate dike. A prospect pit, now partly sloughed, was sunk on the dike (Bundtzen and others, 1992; Miller, Bundtzen, and Gray, 2005). One grab sample of the altered dike contained 54 parts per million (ppm) antimony, 900 parts per billion mercury, 100 ppm arsenic, and 1,000 ppm chromium (McGimsey and others, 1988). The silica-carbonate alteration and the elevated chromium content suggests that the dike was originally of mafic or ultramafic composition.
Workings: Samples were collected by the U.S. Geological Survey and Alaska Division of Geological and Geophysical Surveys in the 1980s (McGimsey and others, 1988).
Alteration: Silica-carbonate alteration of dike.
