Mineralization is hosted in peridotite. The ore body is lenticular in a shear zone. The primary mode of origin was magmatic differentiation. Primary ore control was lithology, with secondary control being faulting. Wallrock alteration is intense (carbonitization). Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges) and/or Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
