During the summer field season of 1967, the Bureau of Mines core drilled two holes on the Keystone properties near the Fairbanks Creek-Wolf Creek divide in the Pedro Dome-Cleary Summit Area; this location is about 20 miles northeast of Fairbanks. The purpose of the drilling was to test at depth the continuity of gold, silver, and base metal (mainly lead and antimony) mineralization that has recently been mined by open cut and relatively shallow underground methods. The two holes were drilled vertically to depths of 716.6 and 690 feet. Assays of samples from each hole established that gold, silver, and base metal mineralization is present at depth, although grade was fairly low.
