Information leading to the delineation of this focus area

Basis for focus area Mining district outlines from McLemore (2017). System perhaps could be best described as Magmatic Au-W-Te.
Identified resources Historical production of gold and silver; early reports of float copper.
Production Elizabeth-Baldy district placers had a total Au production through 1959 of about 146,980 oz.
Status Past mining. No recent exploration as this areas is part of the Boy Scouts Philmont Ranch.
Estimated resources Unknown.
Geologic maps Clark and Read (1972), scale 1:48,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures River gravels derived from alkaline intrusions.
Deposits Unknown.
Evidence from mineral occurrences Anderson (1957).
Geochemical evidence Unknown.
Geophysical evidence Inadequate aeromagnetic and aeroradiometric coverage.
Evidence from other sources Unknown.
Comments Very little information is known about this area because it is private property and the owners have been reluctant to have any mineral resource work done. It is one of the largest primary Au producing districts in New Mexico.
Cover thickness and description Exposed at the surface.
Authors Virginia T. McLemore.
New data needs Alteration mapping, detailed mapping of the plutons and dikes in terms of lithology, geochemistry and mineralogy of the veins.
Geologic mapping and modeling needs Alteration mapping, detailed mapping.
Geophysical survey and modeling needs High resolution, Rank 1 aeromagnetic and aeroradiometric coverage.
Digital elevation data needs Lidar complete.
