McKinley location

The McKinley Mine (also known as the Caballero Mine, Caballero Claims, or McKinley Mine 1880’s, in some sources) is in the draw to the east of the Ready Pay Mine and west of the Stowaway Mine (see 1909 quadrangle map with names added, right).  A pattern which seems to prevail on the western and southern flanks of the mountains on the southern and western edges of Copper Flat.

The McKinley Mine produced gold, copper, and silver from various ores, including:  Calcite, Quartz,  Gold, Copper, Silver, Chalcopyrite, and Argentite. 

The McKinley Mine operated, at times, between 1885 and 1928.  It was owned by Tom Arnett of Santa Rita, New Mexico and Martin Conoby of Hillsboro, New Mexico.

Western Mining History provides these comments about the mine:  “Deposits occur as shoots in a northeast striking vein ranging from 3 ft. to 4 ft. in width.   High-grade seams of ore within the vein range from stringers to 18 in. in width.  Shoots of ore were reported to be 15 ft. to 30 ft. in length and 10 ft. to 20 ft. in height...Vein is part of a radial system of veins associated with the copper flay monzonite porphyry...Workings reported in 1934 (see Harley, Bulletin 10) consisted of a 500 ft. tunnel, another short tunnel, a raise which connects the two tunnels, some drifting and stoping.”  The two photographs above show the interior of the upper adit (tunnel or mine), including the opening of the raise in the lower photograph).  The photograph immediately below is of the interior of the lower adit (all photographs are from a visit on June 12, 2016).
