Location and accuracy The Ruth Creek prospect is on a spur west of Ruth Creek; it extends from an elevation of 1,400 feet south to the top of the spur on the northwest side of Money Knob. It is about 0.5 mile northwest of the center of section 23, T. 8 N., R. 5 W.

Geologic setting

Geologic description

This small old prospect is now part of the large International Tower Hills, Livengood prospect (LD202) that has been intensely studied and drilled since 2006. The Ruth Creek prospect has largely now lost its identity and the data in this record has been integrated into the Livengood record. This record has not been updated since the exploration stated on the Livengood prospect and the pre-Livengood information here is retained in its original form for historical reference.
Gold is found in numerous, nearly vertical quartz veinlets striking S. 20-60 E.; they contain pyrite and arsenopyrite (Mertie, 1918). Some of these veins contain up to 0.58 ounces of gold per ton (Mertie, 1918). The quartz veinlets are cut by calcite veins carrying some gold and sulfides (Mertie, 1918). Contiguous mineralized zones are up to 36 inches wide in altered dolomite-calcite-quartz-sulfide rock (Foster and Chapman, 1967). Small pits expose chromite in serpentinite, and a stibnite vein was uncovered in a placer cut (Joesting, 1942 [ATDM Pamph. 1]; Mertie, 1918).
