A former Cr-Fe occurrence/mine located in sec. 11, T16N, R8E, MDM, about 1.8 km WSW of Nevada City proper, on the N canyon wall of Deer Creek, S of the Newtown-Champion Road, on private land. Discovered and first produced in 1916. Last produced in 1918. Owned by Erwin V. and Emma Cook and Robert L. and Irene Young (100%), California (1976). Operated by the Nevada County Chrome Company (last operator), California (1976). MRDS database stated accuracy for this location is 100 meters. This mine is located on a shallow, SW-trending ridge.
Mineralization is hosted in Late Cretaceous dunite. The ore body is irregular, strikes N45E, dips 90 at a thickness of 6 meters, width of 7.62 meters and a length of 18 meters. Ore body No. 1 is irregular in form & disseminated. No. 2 is lenticular while No. 3 is tabular. The primary mode of origin was magmatic differentiation. Primary ore control was lithology. Wallrock alteration is intense (carbonitization). Local alteration involved the serpentinization of host rock. This deposit occurs in the southern part of an arcuate ultramafic mass that averages ¼ mile wide and extends for more than 3 miles to the NW. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains) and/or Mesozoic gabbroic rocks, unit 2 (undivided).
Workings include surface openings comprised of an open cut 20 to 25 feet wide, about 100 feet long and 20 to 30 feet deep.
Several (three ?) thousand tons of ore were mined from the cut and hauled to the mill for concentration. Recorded figures of the Nevada Chrome Co. production vary but indicate 400 to 500 long tons of concentrate containing about 36% Cr2O3 was made. All but 25 tons of this concentrate came from the Waite property.
