Mine Description

The Richinbar mine is at an altitude of 3,500 feet on the western brink of Agua Fria Canyon, about 4 miles east of Bumblebee and 9 miles by road from Cordes.

From about 1905 to 1908, the Richinbar Mines Company carried on extensive development work at this property, built a 20-stamp mill, and, according to local reports, mined some 8,000 tons of ore that contained about $6 per ton in gold together with a little silver. Lindgren(70) states that, prior to 1922, the mine was operated by three different companies and, in 1917, was unwatered and retimbered. Early in 1933, the Sterling Gold Mining Corporation obtained control of the property and, prior to May, 1934, made some surface improvements and carried on a little underground work. Eight men were employed.

Here, the Agua Fria River has carved a meandering canyon 1,000 feet deep through the mesa basalt and into the underlying pre-Cambrian complex of schist, diorite, and granite.

The mine is on a vein that strikes north, dips almost vertically westward, and occurs principally in schist. Its main or Zyke shaft is 500 feet deep and is reported to connect with several thousand feet of workings that extend northward. When visited in May, 1934, the workings below the 200-foot level were under water. The upper workings are reached by two other shafts north of the Zyke shaft.

As seen in the accessible workings, the gangue consists mainly of coarse, massive, glassy quartz with some tourmaline and carbonate. In the ore shoots, the quartz tends to be more or less cellular to platy. From the surface to the 200-foot level, the ore is mostly oxidized but locally contains pyrite, chalcopyrite, galena, and sphalerite. Most of the ore mined was from three irregularly lenticular vertical shoots. The largest stope seen, which is on the 140-foot level, was about 65 feet long by 55 feet high by 14 feet wide. Throughout its exposures, the vein pinches and swells abruptly.

The schist wall rock shows considerable sericitization and locally contains limonite pseudomorphs after pyrite. Lindgren regards the vein as pre-Cambrian in age.
