A former small surface and underground Au-W-Pb mine group located in the SW ¼ sec. 28, T.22S., R.19E. (protracted), approximately ¾ mile E of the Joiner Camp, on National Forest land. First produced 1900.
Mineralization is partially oxidized gold, tungsten, and minor lead mineralization in pockets and scattered irregularly in quartz veins associated with the contact of a microgranodiorite dike cutting Cretaceous Bisbee Group sedimentary rocks. Ore control was the contact between the dike and the sedimentary group.
Workings are shallow (near-surface). A small amount of gold ore was produced in the group in the early 1900's and some tungsten ore was produced during WWI.
