A former small underground Cu-Pb-Zn-Ag-Au-Mo group of 10 claims (Tip claim; Eureka claim; Stonewall claim; Head claim; Quantero claim; Homestake claim; Look Out claim; Quantrell claim; Elephant claim), plus the patented claims: Top claim; Horse Shoe claim; Grand Prize claim. There are 26 claims in all. These are located in the SW ¼ sec. 4, the SE ¼ sec. 5, and the NE ¼ sec. 8, T.20S., R.14E, 1.25 miles SE of Elephant Head (Pete Mountain), in the northwest corner of the district where the granite mass abruptly terminates in Pete Mountain, where it meets the lowland plains. The upper part of Chino Canyon, at about 1¼ miles from the edge of the mountains, widens into what is known as the Chino Basin, and here, at an elevation of about 5,300 feet, is the Elephant Head group of claims. Discovered in 1910. Owned at times, or in part, by Powers & Stockton; Garrett & Parks; Elephant Head Mining Co. (circa 1915); and the New State Mining Co.
This group of claims trends ENE on dikes of dense greenish-white porphyritic rhyolite cutting the granite. Most prospects are in the sheared and altered sericitized granite and associated with the dikes.
Mineralization is partly oxidized sulfides in a quartz fissure vein and in a sheared and altered zone along rhyolite dikes cutting Laramide quartz monzonite wall rock. Principally lead-silver ores containing some gold and copper and in places a little zinc. The sulphides impregnate the granite very near the surface. Oxidation occurred at near surface. Alteration is sericitization with iron and copper staining of the granite.
Workings include adit and shaft operations plus a 1500 foot tunnel. Worked in the early 1900's and in 1913-1914. The group produced some 950 tons of ore averaging about 8% Pb, 3 oz. Ag/T, and minor Cu, Zn, and Au.
