A former medium-sized surface and underground W-Cu-Au-Ag-Pb mine located on 12 unpatented claims in the SW ¼ sec. 25, T.20S., R.9E., SE of the General Electric group, about 1 mile S of Las Guijas, on private land. Discovered 1916 by L.L. Stewart. First produced 1925. Owned at times, or in part, by the Cleveland Tungsten Co.; L.G. Fernstrom (1941); the F.H. & R. Mining Co.; Carlson; and, I.M. Whitney (1956). Operated by C.C. Calvin (1957). Claims named Guijas Nos. 1-4 and Union Nos. 1-3.
Mineralization is comprised of veins that range from thin stringers to about 18 inches (7.5 cm) wide. These zones are of small, irregular stringers, veins and lenses of quartz with spotty wolframite, scheelite and sulfides along fracture zones in Laramide granitic intrusive at contact with Cretaceous volcanic breccia and biotite minette dike. The vein terminates at the contact with the biotite minette. Ore concentration was epigenetic, epithermal deposits. The ore body is 2.44 meters wide, strikes N65-75W and dips steeply NE.
Local structures include block faulting.
Workings include several shallow shafts, 2 adits and 3 stopes plus extensive open cut operations and are 167.64 meters deep. Prospected originally for Au & Ag, and from WWI through 1972 for tungsten. Over 31,000 pounds of WO3 concentrates were produced.
