| Alvord Mine |
| The Alvord Mine comprises 6 patented claims and one mill site situated in Sec. 1, 2 and 12, T. T 11 N., R. 3 E., S. B. M., in the Alvord Mountains, 6 miles northeast of Manix and 14 miles northeast of Yermo, a station of the Union Pacific Railroad; elevation 2500 ft.; owner, Dellosso Gold Mining Co., F. G. Dellosso, president. Huntington Park, Calif. The property was located in 1885 and operated until 1891 by the Carter Gold Mining Co., of Pasadena, Calif., J. McLore, president. The ore mined was treated in a 5-stamp mill at Camp Cady on the Mojave River. It is reported that they recovered $12.75 per ton by amalgamation with a loss of $1.25 per ton in the tailings. The total production during this period of operation was $50,000. The property was operated from 1906 to 1910 by Alvord Gold Mining Co., of San Diego, Calif. This company installed a 6-Nisson stamp mill. From 1916 to 1920, the Tintic Bonanza Mining Co., of Salt Lake City, Utah; Gidion Snyder, president, operated the property. F. G. Dellosso purchased the property in 1925 and formed the Dellosso Mining Company and patented 6 claims in 1931. The claims are located along a broad belt of crystalline limestone. A dike of porphyritic rock cuts across this belt of limestone at an angle of about 90°. The Principal mineralization occurs east of this dike. The rock is more or less schistose in character, through which at frequent intervals are intruded eruptive dikes. At the east end of the belt is an accumulation of tufa and basalt. The belt strikes E.-W., with a dip of 75° S. The mineralized portion of this lode extends from the porphyry (like east through three full claims and disappears finally beneath the eruptive rocks. The entire lode is gold-bearing, some of the hematite and jasper rock being rich. Gold also occurs in the calcite, though usually lower grade than where accompanied with iron. Iron sulphides also are found carrying gold. The ore mined was limonite and jasper, showing some copper stains. Development on Royal claim consists of glory hole 150 ft. in length and 140 ft. wide. This orebody dips 70° S. The glory hole is 200 ft. in elevation above lower tunnel and 100 ft. above upper tunnel. The upper tunnel is driven east 500 ft. on fissure in limestone. Orebody developed on this tunnel level was 100 ft. in length and 6 ft. to 12 ft. in width; sloped from tunnel level. to 40 ft. of surface outcrop. The lower tunnel is driven east 550 ft. in the foot wall lime At 100 ft. east of the portal, a crosscut was driven south 100 ft. along contact of granite and limestone. At 150 ft. cast of portal, intersected orebody exposed in upper tunnel. Equipment consists of C.P. compressor driven by 15-h.p. FairbanksMorse gas engine. Mill equipment consists of 9-in. by 15-in. Blake type crusher; 6-Nisson stamps; amalgamation plates; and cyanide tanks. Water is secured from well 500 .ft. deep, with a capacity of 5000 gal. per 24 hr., 1-1/2 miles southwest of mine. Two men are employed. Bibl. : State Mineralogist's Reports VIII, p. 499 ; XI, p. 359 ; XIII, p. 319 ; XXVII, p. 281. |
