A former small underground Cu-Ag-Au-Pb-Mn-Mo-Cu mine located on 2 patented claims, in the SE ¼SE¼ sec. 9, T.23S., R.15E, 3500 feet SW of the Tres De Mayo group, on private land. Discovered in 1880 by A.J. Stockton and Associates. Produced 1914-1928. Owned/operated at times, or in part, by Stockton (1880-1886); Ish (1904-1905); Gusteller & Curtis; Las Jarillas Mining Co.; and, E.L. Gross.

Mineralization is lensing fissure veins paralleling diorite dike in quartz monzonite with well-banded quartz, argentiferous galena, and minor chalcopyrite that has been crushed. The ore zone is 1.22 meters wide, strikes N65E and dips steep S to 85NW & vertical. Gouge borders. A few pockets of wulfenite. Oxidized near the surface to drusy quartz, psilomelane, lead anc copper carbonates, and pockets of horn silver. Lead mineralization increased with depth. Wall rock separated from vein filling by gouge, showing slickensided surfaces. The surface oxidation extends to 70 foot of depth. This deposit lies along a fault zone parallel to a contact of Jurassic granite with Precambrian metamorphics. Alteration is oxidation near the the surface. The contacts of diorite and quartz monzonite are usually marked by broad green epidotized belts.

Workings include shaft operations to a depth of 38.1 meters. There were 5 vertical shafts in 1915 at 40, 40, 70, 75, and 125 feet deep in 1915. Mined by Mexicans prior to 1880 and sporadically to 1924. Estimated and recorded production would be some 100 tons of ore averaging about 190 oz. Ag/T, 37% Pb, 0.1 oz. Au/T and minor Cu. $5,000 worth of galena was shipped in 1904-1905. It averaged 40% Pb, 175 oz/t Ag, 1 oz/t Au, and minor Cu.
