|Location and accuracy||This occurrence is on a west-facing slope about 0.5 mile west of hill 1379. It is at an elevation of about 750 feet in the SW1/4 sec. 14, T. 18 N., R. 51 W., of the Seward Meridian. The location is accurate.|
Geologic descriptionThis occurrence consists of a chalcedony-cemented breccia in a flow of fine-grained, dark gray basalt or basaltic andesite (Bundtzen and others, 1998). The breccia contains 1-2 percent, finely disseminated sulfides in both quartz veinlets and in mafic volcanic rock. One grab sample contained 880 parts per billion gold and 200 parts per million chromium (Bundtzen and others, 1998). The elevated chromium probably represent the background of the host rocks.
