A former surface and underground Mn mine located 5 unpatented claims in the NE¼SW¼ sec. 30, T7S, R22E, 12 miles SE of Klondyke, on private land. Discovered in 1951 by J.G. East. Owned by W.M. Cater and Associates. Leased to Rodham and Rutledge in 1952, later to Saber Mining Co. In 1952 a jig plant was built and operated on and off until the middle of 1955.

Mineralization is ore in irregular bands and stringers. Many narrow quartz veins occur, but the major occurrance is within a fault zone. The ore zone is 91. 44 meters long, 18.29 meters wide, striking N70E and dipping vertically. Ore control was a striated slip zone along a fault, forming the southern wall of the fault zone.

Workings total 30.48 meters in length and 18.29 meters deep.

Production was hand-sorted ore and jig concentrates. The entire production from the claims was shipped to the government purchasing depot in Deming, N.M., and totaled 16.5 long tons of hand-sorted ore and 220.5 long tons of jig concentrates. The sorted ore (47.4% Mn) was mined by J.G. East; the concentrates (43% Mn) were shipped by Rodham and Rutledge and the Saber Mining Co. There were less than 1,000 tons of ore remaining in reserves (1962-?).
