This mine, located half a mile south of Clinton switch, is situated on the divide between Benton Creek and Norman Hollow. The main workings consisted of an irregular pit 140 feet long, 110 feet wide, and 40 feet deep, which was sunk on the main outcrop of ore. Several shallow shafts have been sunk in the area surrounding the pit but encountered no ore.
There is no rim-rock from which to determine the probable extent of the ore body. There is, however, an annular outcrop of ferruginous clay and chert breccia fragments surrounding the pit which may outline the extent of the sink structure at this place.
Except at the southwest corner, where massive chert is exposed, the walls of the pit are covered with detritus and no geologic relations can be observed. The south half of the cast wall forms an alcove 50 feet long and 30 feet wide. The pit face here shows five feet of red and purple hematite overlain by seven feet of chert and soil. A tunnel has been driven eastward for a distance of 30 feet into this ore face.
The ore consists of red and specular hematites. An average sample of the latter showed an analysis of 63.38% iron and 0.022% Phos.
This mine has produced 4,580 tons of ore. The deposit is reported to have been but partly opened and that the main portion of the ore body still remains uncovered.
