Location and accuracy The Two Fox prospect (Randolph and Ellis, 1989) is located approximately 1 mile west of VABM Ande and 1 mile east of the head of Stepanof Cove and may represent Christie's (1974) color anomaly 40. The site location is accurate to within 1/2 mile.

Geologic setting

Geologic description

This geothermal area is described by Randolph and Ellis (1989) as being similar to ARDF number UK011 (Steeple Point). The rocks consist of waterlain tuffs and lahars of Quaternary age. The site contains numerous fumaroles and hot-springs and is marked by a 7,000 by 4000 foot color anomaly. It consists of acid-leached rocks and localized silica stockworks. Some of the fumarolic centers also display strong silicification and pyritization. Hot-spring centers exhibit silicification and chalcedonic breccias. Combined metal values from 55 samples obtained here and at Steeple Point (ARDF number UK011) are up to >2000 ppm arsenic, 115 ppb gold, >5 ppm mercury, 11 ppm molybdenum, and 4.4 ppm silver.
