A former small Pb-Zn-Ag-Cu-Au group of mines located on 6 patented claims (1964), in the SW ¼ sec. 27, NE ¼ sec. 33 and the NW ¼ sec. 34, T.14S., R.27E, about 1½ miles NE of Dos Cabezas, on private land (location given is for the southernmost shaft). Discovered 1890. Produced 1890-1953. Owned/operated at times, or in part, by the LeRoy Consolidated Mines Co.; the Leroy Conservation of Mines; Dorsey Brothers; Rice Brothers; Ariland Mines Co.; Areland Mining Co.; VMP Leasing Co.; Frank Peterson; Miller Leasing; Z.P. Issacson; and, Bean. Additonal holdings in T14S, R27E, sec. 33 NE¼ and sec. 34 NW¼.
Mineralization is scattered bunches and disseminations of sulfides in irregular, coarsely-textured, cross-cutting quartz veins along fault and shears cutting Precambrian granite rocks, accompanied by intrusive diabase dikes. The ore zone (and most veins) strike NE and dip 65SE. The ore vein at the Oneida tunnel strikes N-S and dips 64W and is 2 feet in width.
A quartz monzonite body is in fault contact with Cretaceous sediments to the north and in concordant contact with Cambrian sediments to the south. E-W trends exist on the bedding and on the fault. Faulting and shearing within the quartz monzonite cuts ore veins.
Workings include shaft(s). There are 2 shafts, the Climax and Leroy, and numerous tunnels. There are at least 2000 feet of workings in Climax; 3 levels, 1500 feet workings on the Leroy; 3 levels, and one tunnel on the Oneida, is 500 feet long, with 500 feet of side drifts. Workings are collectively 1,219.2 meters long and 137.16 meters deep. The group produced a few thousand tons of ore in the 1880's and some 4,000 tons intermittently in the 1900's up to 1950.
