Location and accuracy This occurrence is at an elevation of about 2,800 feet on a ridge approximately 1.5 miles northwest of Baldry Mountain. The site is at Alaska Division of Geological and Geophysical Surveys (ADGGS) sample station 96KC067 (Liss and others, 1997), at the west-central edge of section 25, T. 6 N., R. 14 W., of the Fairbanks Meridian. The location is accurate within 500 feet.

Geologic setting

Geologic description

This occurrence is near the axis of a northeast-trending, overturned syncline composed mainly of lower Paleozoic(?) sericitic chert and siliceous argillite (Reifenstuhl and others, 1997 [PDF 97-15a]). The chert and argillite are cut by northeast-trending thrust faults.
A sample (96KC067) of vuggy, limonite- and manganese(?)-stained quartz in black quartzite or chert on a ridge northwest of Baldrey Mountain contained 240 parts per million (ppm) copper, 419 ppm molybdenum, 114 ppm lead, and 560 ppm zinc (Liss and others, 1997). There is no record of exploration or mining at this site.
