A former B(borates) deposit/mine located in the NW¼SW¼NW¼ sec. 10, T8N, R1E, SBM, 4.6 km (2.9 miles) ENE of Daggett Ridge (coordinates of record) and 7.0 km (4.4 miles) S of Daggett (town), on private (patented) land. Owned by the Columbus Borax Company (1898>). First produced in 1897. MRDS database stated accuracy for this location is 10 meters.
Mineralization is hosted in rocks of the Tropico Group, Barstow Formation (lake sediments, Miocene shale). Local rocks include Miocene nonmarine rocks and/or Plio-Pleistocene and Pliocene loosely consolidated deposits.
Workings include unspecified underground openings.
B-bearing shale was mined and processed. In many places, the borates were not visible, but the shale had a distinctive color(s).
Analytical data results: Some ore was reported in 1903 to average 15% B2O3.
