A former small underground Cu-Ag-Au-Pb-Mn-Zn-Sb mine located in the center of the SE¼ sec. 31, T22S, R16E, on a group of 12 claims adjoining the World's Fair property on the SW and the Three R group of claims on the NW, ½ mile SW of the World's Fair Mine, in Flux Canyon, 8 miles SE of Patagonia; 2 miles NW of Harshaw, on National Forest land. Discovered in 1875. Owned/operated by E.E. Bethel, of Patagonia; the Calumet and Arizona Copper Co. (1 year lease, early 1900's); the Wonder Mining Co. (R.W. Coleman and Associates); Mr. John Glasson; the Washington Trading Co.; Hosier and W.H. Worthington; A.L Harroun and Associates; Howard E. Davis; Bracey Curtis; and, L. Lindsay.
Mineralization is ore in stringers in a complex system of fisure veins, including the NW-trending Flux vein and NE-trending World's Fair vein. The ore zone is 3.66 meters wide. Alteration includes volcanics locally much altered to quartz, sericite, epidote, pyrite, carbonate, and chlorite and with strong hornfelsitation in places. The surface croppings are heavily stained with Mn and Fe.
Local structures include a N60E-trending silexite dike. A general structure common to regional formations is a sheeting which dips 40NNW.
Tectonic elements include the Alum Gulch Fault Block.
Workings include shallow shafts to depths of 50 feet or more, aggregating about 500 feet of work (circa 1915). Ultimately the workings totaled 243.84 meters in length and 70.1 meters deep. Developments included several shallow shafts, each about 50 feet deep; a 230 foot deep shaft with drifts extending N and S from the 110 foot level; a 600 foot long tunnel; 460 feet of drifts; and the 70 foot deep inclined Kemp shaft, which is located to the NW, across Flux Canyon, on a fault zone which strikes N30-40W and dips 40 SW. Leased to the Calumet & Arizona Copper Co. and was being developed at a substantial rate (circa 1915). No record of production.
