Information leading to the delineation of this focus area

Basis for focus area Mining district boundaries from McLemore (2017).
Identified resources Historical production of manganese.
Production As of 1957, total production in the Luis Lopez district was 97,000 short tons of concentrate that averaged about 41% Mn and 18,000 short tons of crude ore that averaged 28% Mn (Willard, 1973).
Status Past mining.
Estimated resources Unknown.

New data needs This area needs detailed 1:12,000 mapping, chemistry, alteration mapping.
Geologic mapping and modeling needs Detailed geologic and alteration mapping.
Geophysical survey and modeling needs High-resolution, Rank 1 aeromagnetic and aeroradiometric survey (new geophysical survey submission for Socorro).
Digital elevation data needs Lidar most complete; northeastern portion in progress.
