A Cu-Ni occurrence/mine located in secs. 2, 3, and in the NW¼NW¼ sec. 11, T16S, R9E, SBM, 3.1 km (1.9 miles) S of Carrizo Mountain (coordinates of record) and 9.0 km (5.6 miles) NNW of Coyote Wells, E of Fossil Canyon, on Bureau of Land Management administered land (located claim) (now on wilderness land ?). Owned by Minnie & Lloyd Ross O'Callaghan (?), Ocotillo, California and by Toilmon Roark of....(incomplete data). MRDS database stated accuracy for this location is 100 meters.
NOTE: The geographic coordinates presented are taken from the topo map at the adit symbol in the NW¼NW¼ of the section stated. The MRDS file presents coordinates placing the locality further S in the section than that described in the same file.
Mineralization is hosted in peridotite. 3 principal mappable units underlie the area: 1) peridotite, mainly serpentinized olivine and enstatite; 2) Quartz diorite; and, 3) layered bentonitic claysand sandstone of the marine Miocene Imperial Formation. Serpentinized peridotite and quartz diorite were intruded by simple pegmatite bodies. 3 faults that may have localized nickel mineralization occur in the area and form boundaries between the 3 units. Nickel occurs in basic intrusive peridotites that intrude into metasedimentary rocks. Fractures and nearly vertical faults in the peridotites are the loci of accumulation of secondary iron minerals and some pale blue secondary nickel minerals including garnierite and morenosite. Metasediments occur along the NE side of the Elsmore fault zone for about 9 miles in the Coyote Mountains. Peridotite in the mineralized zone is highly altered. Associated rocks include diorite. Local rocks include pre-Cenozoic granitic and metamorphic rocks undivided.
Workings include unspecified surface and underground openings (the topo map reflects 1 adit symbol labeled "tunnel" at this point in sec. 11).
Analytical data results: Assays range between 0.14 and 1.99% Ni, averaging 0.66% Ni.
