This mine, located two miles northwest of Winkler, is situated near the head of a ravine tributary to Norman Hollow. The main workings consist of a pit 250 feet long, 150 feet wide, and 20 feet deep, on the south and west sides of which three shafts have been sunk on the contact between the ore and the wall rock. Each shaft encountered ore on the pit side while the opposite walls consist of steeply dipping dolomite. The two southernmost shafts are connected at a depth of 50 feet by a drift which was driven the entire distance in ore. The third shaft, located near the northwest corner of the pit, is reported to have encountered ore throughout its entire depth of 93 feet.
One-hundred yards north of the main workings a small cut has been driven 40 feet into the hill. The face consists chiefly of chert cemented with specular ore and limonite.
The ore consists chiefly of soft red and specular hematites. It contains considerable copper carbonate which occurred in thin seams. An analysis of the soft red hematite ran 54.90% iron and 0.017% Phos.
The mine has not been operated since 1880 up to which time it produced 5845 tons. From the reported occurrence of ore in the shafts and connecting drift, there is apparently a large proportion of the ore body that has not been mined.
