A group of 19 Cu-Ag claims lying north and east of Bond's Camp, which is 1¼ miles north of Alto. Owned by Josiah Bond. Workings known as the Bonanza tunnel were on the Tennantite unpatented claim adjoining the Bonanza patented claim.
The country rock is a somewhat tuffaceous latite of dark green color. Along its eastern border; however, the formation contains so much granite porphyry, apparently in the form of included boulders and pebbles, that it has been mapped as granite porphyry. The rock is cut by a large number od small fissures which trend about east. the principal strikes being N.85ºW. As many as 50 small veins were noted in a distance 0of ¾ mile north from Bond's cabin. The quartz veins are mostly rather small but range up to 4 feet in width. They are stained with iron and manganese and in places show copper carbonates at the surface. Owned by the Bond Mining Trust (1962).
