Location: This occurrence is situated near the summit of Lone Indian Mountain at an elevation of 2,600 feet (792 m) in Section 29, T. 20 S., R. 23 E., of the Kateel River Meridian.
Geology: The Lone Indian Mountain occurrence consists of a ferrigenous quartz-bearing gossan hosted in PreCambrian and Paleozoic schist and marble (DiMarchi and others, 1994). Some quartz-eyed schists in the section are thought to be metavolcanic rocks (Patton and others, 1980). No dimensions of the mineralized zone are given. No ore minerals were recognized. Grab samples of ferricrete gossan collected by DiMarchi and others (1994) contained 803 ppm copper, 148 ppm zinc, and 803 ppm lead. A stream sediment sample collected in Bridge Creek to the west contained 210 ppb gold.
