In 1949~ silver ore was produced from Cambrian limestone at the Tilford Mine. According to Hose, Blake, and Smith (1976, p. 47), “a narrow calcite vein shows iron and copper stain, and a stope and winze on a narrow fracture may have yielded the 16 tons of ore reported to contain 1 oz gold and 532 oz silver.” This narrow vein was not found during the present investigation; however, several small north- to northeast-striking faults were mapped in the mine (fig. 4), and analyses showed zinc, silver, and a trace of gold in samples from this mine (table 5). These faults could not be traced into the roadless area; however, similar, faulted Cambrian limestone host rock was mapped by Hose (1981) in the area. Total production, all from workings outside the roadless area, for the district through 1954 was 4,655 oz gold, 4,535 oz silver, 179 lb copper, 38,948 lb lead, 44 lb zinc, and 337 short-ton units of tungsten.
