Sec 6 T30N R38E. In opalite.
Alteration: Argillization Of Adjacent Sediments
Commodity: Erratically distributed in irregular opalite beds
Deposit: Disseminated and streaky cinnabar occurs in light grey opalite. The opalite is probably a replacement of tuff and pebbly tuff. The fine-grained opalite unit may be only 1-2 m thick, although it is not anywhere completely exposed. Argillized olive tuffaceous sediments are adjacent to the opalite. The opalite underlies a ridge-capping tertiary basalt flow unit. Ore is presumably at the same stratigraphic horizon As that at the goldbanks mine, and it has the same general character with finely divided cinnabar coloring favorable parts of the opalite blanket. Locally the opalite is unusually vuggy with irregular cavities lined with clear crystals of post-cinnabar quartz. Ore lacks continuity.
Deposit type: Hot-spring Hg
Development: In 1940, the pronto plata claims 1-9 and the red hill claim were located, and later about 50 more pronto plata claims were added. In 1942 and 1943, the bradley mining company did considerable exploration by means of about 20 bulldozer cuts, short adits, and scattered pits over about 0.5 sq mi. The largest cuts are below the small cabin on the property and consist of a 400-ft-long gash along the hillside, and 2 other cuts about 140 ft long, diverging from it and trending at right angles up the hill. In spite of extensive exploration, the only production has come from test runs of ore hauled to the bradley furnace at opalite, and by aug 1943, the property was idle. title to the property was retained by h. W. Baldwin until 1962 with additional exploration done under lease by stanley johnson in 1958, colgate corp of los angeles in 1959, and c. R. Bis-hop and t. R. Moxness in 1961, but none of these achieved any production. Baldwin dropped the property in 1962, and it was restaked by others (possibly kennecott?). In 1984, recent rotary drilling and roads north of the old pit 200+ m were noted, possibly by kennecott.
