A former Ag-Au-Pb-Zn-Cu-As-Mo occurrence/mine located in the NE¼NE¼NW¼ sec. 11, T23N, R18W, G&SRM, ¾ mile SE of Chloride and about 2.1 miles WNW# of Cherum Peak, on Bureau of Land Management administered land. Discovered in 1885. The property is comprised of 2 claims. Previous pwners and operators include the Philadelphia and Arizona Mining Company, John BArry, Kelly and McKennon, the Lehigh-Arizona Mining Company, Huffman and Rae, Tom Rice, Relord, Minnesota Mining and Milling, R.D. Aeigler, P.S. Virgin, Fred Ruinniger, and Lindsey and Tillings. Owned by Minnesota-Connor, New Jersey (1957). Operated 1901 through 1948. The USGS MRDS database stated accuracy for this locality is 500 meters.

MINNESOTA-CONNOR MINE.

Location. The Minnesota-Connor mine, one of the more important properties of the district, is about 1¾ miles southeast of Chloride and half a mile south of the Pay Roll mine, at an elevation of about 4,400 feet. It lies at the head of an open gulch which drains southwestward into Sacramento Valley. It is reached by good wagon roads of easy grade from the northwest and the southwest.

History and ownership. The property is owned by the Philadelphia and Arizona Mining Company, of Philadelphia, to which it was sold by John Barry about 1902. It consists of two claims, the Minnesota and the Connor, joining each other end on. The property was located in the early eighties, since which time it has been a good producer, having yielded several hundred thousand dollars' worth of rich ore. In the early days the surface ores were worked by chloriders with handsome returns. Later the mine was leased to Messrs. Kelley and McKennon, under whom also it was a prolific producer. During the. last, few years the property has been leased to a new organization, the Lehigh-Arizona Mining Company.

Vein and ore. The country rock is the usual pre-Cambrian complex, which here consists mainly of pressed microcline-biotite schist, hornblende schist, gneiss, and syenite. It is cut by dikes of vogesite or kersantite, which locally occur on either wall, by dikes of pale pinkish pegmatite or aplite, and by seams of epidote one-eighth to one-quarter inch thick.

The vein strikes N. 30° to 50° W. and dips 60° to 80° SW. It is known to extend through a horizontal distance of 2,400 feet and varies from 5 to 20 feet in width. Where exposed on the surface and in the shallow shaft southeast of the mill it stands about vertical and is 5 feet in width, but it is reported to flatten and widen as it goes down and in the deeper part of the mine it has in places a width of 20 feet of good ore.

The gangue is quartz, with some calcite, which locally seems to replace the quartz. The ore contains pyrite and arsenopyrite, as well as some chalcopyrite. The principal value is in silver, which in part is in the form of ruby silver, but the ore also contains some gold. Part of it is very rich, some large bodies running $200 or more to the ton. The production is reported to be about $100,000.

The property is developed to the maximum depth of 570 feet by four shafts and four levels, containing about 2,500 feet of drifts and other work approximately as shown in figure 9. The principal equipments are a very complete mill and hoists.

Owing to suspension of operations and the presence of water, the mine was not accessible at the time of visit, except the Connor shaft, northeast of the main workings, Here on the 50-foot level fair bodies 0of rich ore were found for a distance of 360 feet to the southeast of the shaft.


Mineralization is a vein deposit hosted in schist and gneiss. The ore body strikes N40W and dips 70SW at a width of 6.1 meters (20 feet) and a length of 731.52 meters. The mineralization is associated with a Late Cretaceous porphyry intrusion. Associated rocks include Neoproterozoic granite. Local rocks include Early Proterozoic granitic rocks.

Regional geologic features include Precambrian schistosity that strikes N30ºE. Veins, fissures and dikes strike NW to NNW regionally.

Workings include underground openings with a length of 762 meters and an overall depth of 173.74 meters and comprised of 4 shafts with 4 levels, all interconnected.
