A former underground Au-Ag occurrence/mine located in the NW¼ sec. 23, T19N, R20W, just SE of Oatman, on the Tom Reed vein. Owned by the Gold Road Company; Tom Reed Gold Mines Company (1906- ). Started in 1901. Reopened in 1908 and closed March, 1932.

The Tom Reed deposit occurs in Oatman Andesite and the vein strikes NW-ward and dips steeply NE-ward. Mineralization is a vein deposit. Structure involves NW-trending faults and veins. The Tom Reed vein is offset by the Mallory fault near the Big Jim Mine. The Mallory fault strikes NW but dips 60º to 70º SW. The ore body is lenticular. Pyritized areas are more altered. Bleaching, kaolin, calcite, and chlorite have formed. Ore control involved the vein following the NW-trending fault zone.

Workings include the Tom Reed shaft at 100 feet deep (1933). A 20-stamp mill was erected on site (1904). Production for the period 1908 - 1913 was some $13,053,000 (period values).
