A former small Pb-Ag-Au-Cu mine located in the NW ¼ sec. 6, T.22S.,R.19E. (protracted), on the northern margin of the Huachuca Mountains, ½ mile south of the Canelo-Fort Huachuca Road. Produced 1924-1926, 1928, and 1949. Owned at times, or in part, by the Huachuca Consolidated Mining Co.; the Huachuca Queen Mining Co. (circa 1926); and, the Border-Land Metals Co.
This mine had to cease operations when it was discovered that the workings were on the Fort Huachuca military reservation.
Mineralization is cerussite along steeply dipping (65NW) fissure veins cutting badly faulted and broken Paleozoic and Cretaceous sedimentary formations under the overthrust fault plane. Ore concentration was leaching.
The Crest Line fault is the major geological structure associated with this mine. It thrust Paleozoic limestones over Lower Cretaceous strata, mostly red shales and sandstone. The fault surface dips to the north less than 10º. The overthrust plate of Paleozoic limestone has largely been removed by erosion, so that it is now less than 100 feet thick. The thrust fault is east of the deposit.
Workings include tunnel and shaft workings. The main vertical shaft was reported to be 300 feet deep in 1925. Over 400 tons of ore were produced in 1924-1928 and some 16 tons in 1949.

Description: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone. This unit includes the Tapeats Sandstone, Bright Angel Shale, Muav Limestone, Temple Butte Formation and Redwall Limestone in northern Arizona, and the Bolsa Quartzite, Abrigo Formation, Martin Formation, and Escabrosa Limestone in southern Arizona. These rocks record intermittent sea-level rise and inundation in early Paleozoic time. (330-540 Ma)
