A former B-borate mine located in sec. 6, T25N, R3E & in sec. 31, T26N, R3E, SBM (the mine complex proper is in sec. 6 at the sec. 5 boundary. Based on the topo map, a minor portion of the property is probably in sec. 31, T26N, since the mine complex proper is also on the boundary line of that T&R sec.), 2.4 km (1.5 miles) NNW of Ryan (adjacent to Dantes View Road), on National Park Service land (Death Valley National Park). Property was private when the mine was operating, may now be public national park land. Owned & operated by the American Borate Co. (1991). Operated during the periods 1974-1978, 1980-1986, 1991 to present (1993). MRDS database stated accuracy for this location is 500 meters. Inyo County conditional use permit 76-5 applied.

Mineralization is a lacustrine borate deposit (Mineral occurrence model information: Model code: 260; USGS model code 35b.3; Deposit model name: Lacustrine borates), hosted in rocks of the Laohuling Formation (shale, clay, mud, mudstone, siltstone and sandstone) and/or the Furnace Creek Formation. The ore body is 76.2 meters thick with a width of 274.32 meters and a length of 1,125 meters. The ore ranges from 200 to 1,350 feet deep. Associated rocks include Pliocene - Miocene basalt. Local rocks include Tertiary nonmarine rocks, undivided and/or Quaternary alluvium and marine deposits.

Local structures include a NNE-trending, steeply-dipping fault.

Related tectonic structures: Basin and range province.

Workings include underground openings. The ore body is in Death Valley National Park and the portal of the mine is 1,500 feet W on Bureau of Land Management land. The ore was mechanically enriched at the mine, calcined in Nevada, and ground at Dunn siding. No further dat on the workings in either USGS MRDS file.

Reserve-Resource data: Estimate by G. Orris from published data in 1990.
Also, Roskill (1993); Evans and others (1976).

Reserves and resources data: Type: in-situ; estimate year: 1976: total resources: 4,421,000 metric tons of ore. Estimate year: 1992: total resources: 11,800,000,000 metric tons of ore.

Assay data: Year: 1976: B-borates: 22 weight per cent; 1992: 21 weight per cent.
