Crawford Mountains

The Crawford Mountains is a phosphorus-phosphates mine located in Rich county, Utah at an elevation of 6,299 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Land Status

Land ownership: Mixed
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Geology): The Phosphoria Formation Is Subdivided Into Five Members By Mckelvey (Bibliography Ref. L010), Two Of Which (The Meade Peak And Retort Members) Contain Significant Phosphate Deposits. In Utah And Southwestern Wyoming, The Meade Peak Member, And In Central And Northwestern Wyoming, The Retort Member Contain The Deposits Of Potential Interest. The Park City Formation Of Utah And Central Wyoming And The Shedhorn Sandstone Of Northwestern Wyoming Are Stratigraphic Equivalents Of And Intertongue With The Phosphoria Formation. The Phosphoria Formation And Equivalent Formations Are Underlain By Either The Tensleep Sandstone, Weber Quartzite, Wells Formation, Or Diamond Creek Sandstone And Are Overlain By Either The Woodside Or Dinwoody Formations.

Comment (Names): Other Names: Arickaree Mine, Cherokee, Pawnee, Mandan, Emma, Tuscarora, Rex Peak, Bradley, Sioux, Pearl, Crawford Group.

Comment (Production): The Arickaree, Cherokee, Pawnee, Mandan, Emma, and Tuscarora Mines Have Produced Phosphate Rock At Various Times Between 1907 and 1975, But No Production Figures Have Been Released By The Present Owner, Stauffer Chemical Company, Or By The Previous Owner, San Francisco Chemical Company. Production From Other Mines in the area is not known, but is minor.

Comment (General): Also part of the Western Phosphate Field.

Comment (Deposit): This Minerals Availability System Evaluation Was Done As Part Of A 1980 Study Of Utah And Wyoming Phosphate Deposits By The Intermountain Field Operations Center, Denver, Colorado. Domain - The Outcrop Area Falls Roughly Equally On Private Land (Patented Claims) And U.S. Bureau Of Land Management Land With One Section In The Rex Peak Area On State Of Utah Land.

Comment (Ownership): Phosphate Lands May Be Leased From The U.S. Government. Currently, There Is One Active Federal Lease Within The Area Included In This Deposit. The Land Controlled By Stauffer Chemical Co. Is Partially Composed Of Patented Claims Under Perpetual Lease And Partially The Federal Lease Mentioned Above. The Percent Ownership Figures Given Are Approximations Based On Outcrop Strike Lengths.

Comment (Economic Factors): Mining and beneficiation costs for each proposed operation were obtained by applying one of 34 basic mine models and 5 basic mill models developed for evaluating Utah and Wyoming phosphate deposits. Site-specific cost adjustments were made for land acquisition, infrastructure, unusual haulage distance to mill, the presence of multiple beds requiring mining of waste, and mill feed grade and recovery. All costs are in January 1980 dollars. The schedule of costs is based on the assumption that each proposed operation will be independently developed as soon as technically possible after the official January 1979 base date for the current phosphate study. Thus, land acquisition, exploration, and infrastructure capital costs are assumed to begin in 1979. Mine and mill capital costs include a contingency allowance of 15 percent of all other capital costs except working capital. Mine and mill working capital is estimated at 60 days of operating cost. A Bureau costing manual (bibliography data set ref. I030) was used to estimate surface and underground mine exploration, development, reclamation, plant, and equipment capital costs; underground mine operating costs; capital and operating costs for the calcining-hydration mill (if used) and for the flotation sections of other mills; costs of transporting products from proposed mills to existing final processing plants; and access road construction cost. Surface mine operating costs are size-scaled, using scaling factors from Bennett (bibliography data set ref. I001), and others (U.S. office of audit and investigation) for Idaho phosphate mines in 1976 and 1977. Infrastructure capital costs assigned to each proposed mine consist of only those railroad, transmission line, and access road costs which are needed for development of each mine. Railroad cost is estimated by the Richardson rapid construction cost estimating system (bibliography data set ref. I020). Transmission line cost is estimated from typical industry costs (A.W. Watts, 1980, Water and Power Resources Services, personal communication). Access road costs are estimated by using the capital and operating cost estimating handbook (bibliography data set ref. I030). Land acquisition costs are based on typical competitive bids for leases in southeastern Idaho, adjusted for specific deposit grade and thickness. Lease rentals and royalties are based on current rates for federal leases in the western phosphate field. Capital and operating costs for all mills, excepting the calcination-hydration mill (if used) and flotation sections of other mills, are size-scaled, using scaling factors from Bennett (bibliography data set ref. I001), from costs given for a sizing and calcining mill described by de Voto, et al. (bibliography data set ref. R030), vol. 2, appendix d. Site-specific cost adjustments for mill feed grade and recovery are made, using relative cost factors calculated from average cost and recovery curves for altered and unaltered ores (bibliography data set ref. I010).
