in the Black Range and a listing of minerals from the mining districts in the Black Range.
Vanadinite is a secondary mineral found only in arid regions of the world. It forms from the oxidation of lead based minerals. The Hillsboro Mining District is the type locale for Arsenian Vanadinite.
The main shaft at the site is covered partially by boards from the mine frame (see photograph above and those on the following pages - taken on March 27, 2016). This is basically an open shaft and caution should be exercised in its proximity. There are other diggings in the proximity of the shaft, including some trenching.
The map and legend (below) showing the Vanadinite Mine in relationship to other mines in the immediate area is from The US Geological Survey Bulletin 1876, “Mineral Belts in Western Sierra County, New Mexico, Suggested by Mining
Districts, Geology, and Geochemical Anomalies”, 1989, p. 34.
A photograph of a Wulfenite specimen, PbMoO4, from the Macy (Vanadinite) Mine is shown on the following page. The specimen is at the Mineral Museum, New Mexico Institute of Mining and Technology, in Socorro, New Mexico. Photographs of minerals were taken on April 6, 2016.
Vanadinite and Calcite were also mined at the site and specimens from the mine are also shown here. Both are part of the collection of the Mineral Museum of the New Mexico Institute of Mining and Technology at Socorro, New Mexico.
