The Crater Bench (Abraham or Baker Hot Spring) mining district is in south-central Juab County, about 19 mi north-northwest of Delta. The district was a small Mn producer in 1929β30. Total district metal production at modern metal prices is estimated at $246,000. The Iron King is the only mine known to have shipped ore from the district (Crittenden, 1951).
The Crater Bench district lies along the broader Deep CreekβTintic mineral belt in the Basin and Range Province of western Utah. The district lies on the east flank of Crater Bench, a 7-mi-diameter, 600-ft-high, Pleistocene (0.9 Ma), basaltic shield volcano (Crittenden, 1951).
The mineralization at the Iron King mine occurs as a discrete Mn layer in an otherwise barren calcareous tufa mound about 1600 ft in diameter and 15 ft high (Callaghan and Thomas, 1939). The Mn occurs as a single thin lens interbedded with the barren porous calcite near the top of the tufa dome (USGS Model 25g). Average shipped grades are 20.8% Mn. The principal ore minerals are psilomelane and pyrolusite (Callaghan and Thomas, 1939). The mine workings consist of very shallow pits and trenches.
