Mineralization is a replacement deposit hosted in greenstone and serpentinite. The ore body strikes N25E and dips 85W. Ore controls included fractures. A ledge of hard, fine-grained, gray diorite betwee a greenstone footwall and a serpentine hanging wall has been replaced by ore. Local rocks include Mesozoic granitic rocks, unit 5 (Klamath Mountains) and/or undivided pre-Cenozoic metavolcanic rocks, unit 2 (undivided).
Analytical data results: The owner claimed assays of 11% to 14% Cu.
Diamond drill holes failed to find enough Cu ore to encourage development in 1953.
