Geologic setting

Geologic description

Prospect hosted in Ambler sequence of metamorphosed Devonian and Mississippian volcanic, volcaniclastic, and sedimentary rocks. Ore minerals are concentrated in a felsic tuffaceous sedimentary section of rocks containing numerous basalt sills and flows immediataly above a basal carbonate section (Hitzmann and others, 1986, p. 1592-1618). Two mineralized horizons are identified having a strike length of about 5000 ft (1.6 km) (Nana Development Corp., written communication, 1997).

Additional comments

Bud Group claim (near VABM Ruby) may be located two km west of the location shown of the Sunshine Creek prospect shown here. This discrepancy may be due to changes in claim group names and locations during various years (unpublished information, Kennecott Exploration Co.).
