Information leading to the delineation of this focus area

Basis for focus area Focus area outlines northeast trend of barite mines and prospects in southern Stevens County.
Identified resources Identified resources and historical production of barite.
Production Several deposits shipped a few hundred tons of ore in the 1940s.
Status Past mining.
Estimated resources Combined reserves of the Deer Park Barite No. 1 mine and Shallenberger mine: 8,000 tons of Measured and Indicated ore and 10,000 tons of Inferred ore. Allan barite mine: At least 1,400 tons of Measured and Indicated ore and 2,750 tons of Inferred ore. Cardinal mine: At least 1,100 tons of Measured and Indicated ore and 6,800 tons of Inferred ore are present at the site of the current mining operations.
Geologic maps Miller (1996), scale 1:48,000; Campbell and Raup (1964), scale 1:48,000.
Geophysical data Inadequate Rank 3 to 4 aeromagnetic and Rank 4 aeroradiometric coverage.
Favorable rocks and structures Mineralization of Precambrian aged sedimentary rocks of the Deer Trail Group, northeast-trending veins following bedding.
Deposits Shallenberger deposit (MRDS dep_id: 10180808), Allan barite, Cardinal barite mine (MRDS dep_id: 10204670), Deer Park, Hillside.
Evidence from mineral occurrences MRDS; Moen (1963).
Geochemical evidence No data.
Geophysical evidence Unknown.
Evidence from other sources None.
Cover thickness and description Exposed at the surface.
Authors Daniel W. Eungard.
New data needs Geologic mapping, geochemistry.
Geologic mapping and modeling needs Existing mapping is at too coarse of resolution to show veins or bedding that control ore deposition. Major structures are well known but local structures could be identified.
Geophysical survey and modeling needs Not applicable to barite deposits.
Digital elevation data needs Lidar complete.
