A former small underground Pb-Ag-Cu-Zn-Au mine located in West-central sec. 11, T.17S., R.12E. (Twin Buttes 15 minute topo map), near the Olivette Mine and ½mile south of San Xavier on private land. Produced 1900-1948. Owned/operated at times, or in part, by the Whitcomb Mining & Milling Co.; and the Associated Mining & Milling Co., Ross Barkley, and J.E. Fisher.
Mineralization is partly oxidized lead-silver and minor copper and zinc minerals in replacement lenses, nodules, and pockets along a quartz fissure zone in altered and brecciated Cretaceous sedimentary and volcanic rocks within the San Xavier thrust fault sheet. The Cretaceous rocks are composed of arkose, quartzite, conglomerate, shale, limestone, andesite, and rhyolite.
Workings include an inclined shaft operation. Worked sporadically from the early 1900's to 1948, producing some 900 tons of ore averaging about 8% Pb, 9 oz. Ag/T, 0.75% Cu, 0.5% Zn and minor Au.
