Information leading to the delineation of this focus area

Basis for focus area Mining district boundaries from McLemore (2017).
Identified resources Historical production of barite, fluorite, lead, silver, and zinc.
Production 37,500 tons barite (Williams and others, 1964).
Status Past mining; current mineral collecting.
Estimated resources Unknown.
Geologic maps New Mexico Bureau of Geology and Mineral Resources (2003), scale 1:500,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Mineral deposits principally occur in the Council Spring member of the Pennsylvanian Madera Group limestone. Minor vein fillings occur in Permian sedimentary rock as well as Proterozoic basement rocks (Rakovan and Partey, 2009).
Deposits Blanchard mine (MRDS dep_id: 10150896).
Evidence from mineral occurrences MRDS; New Mexico Mines Database (McLemore and others, 2005).
Geochemical evidence See Rakovan and Partey (2009).
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments Drill core at NMBGMR. Although the Hansonburg Mining District is rich in barite-fluorite-galena ores it has seen relatively little metal production throughout its history because of metallurgical problems in separating the mixed ores (Rakovan and Partey, 2009).
Cover thickness and description Exposed at the surface.
