Information leading to the delineation of this focus area

Basis for focus area Known Mississippi Valley-type deposits with Pb, Zn, and barite production, and Sr occurrences.
Identified resources Historical production of barite, lead, and zinc.
Production Lead with minor Zn were the major products until 1910; following 1910 barite was produced with lead and zinc as byproducts. This district produced more than 400,000 tons barite (Wharton and others, 1969).
Status Past mining.
Estimated resources Unknown; barite contains up to 2% strontium.
Geologic maps Middendorf (2003), scale 1:500,000.
Geophysical data Inadequate Rank 4 and 5 aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Cambrian, Ordovician, Mississippian carbonates.
Deposits Blue Jack mine (MRDS dep_id: 10184422), Crystal mine, C. Weber mine, Ford-Grey mine (MRDS dep_id: 10147885), Goller No. 3 mine (MRDS dep_id: 10147044), Hincke-White No. 1 mine.
Evidence from mineral occurrences MRDS; Missouri Geological Survey database Inventory of Mines; Occurrences and Prospects (Missouri Geological Survey, 2021b).
Geochemical evidence Unknown, may be data in files at the Missouri Geological Survey; known favorable mineralogy.
Geophysical evidence No data.
Evidence from other sources Drill core and mine information.
Cover thickness and description Less than 1000 feet.
Authors Cheryl M. Seeger.
New data needs Drill core logs, new 1:24,000 scale geologic mapping. Geochemical sampling of mine waste.
Geologic mapping and modeling needs Modern 1:24,000 scale geologic mapping, drill core logs, and 3-D geologic modeling.
Geophysical survey and modeling needs None-high resolution aeromagnetic and aeroradiometric coverage complete.
Digital elevation data needs Lidar QL2 over part of the focus area; in progress and inadequate in other parts.
