Vanadinite Mine Location

This mine overlooks the Percha Box.  It is known by a variety of names, including; the Macy Mine, the Percha Mine, the Vanadinite Mine, the J. C. Macy Claim, the Barking Frog, and the Bobbee De Claim.  On the Hillsboro Quadrangle Geologic Map the mine is named the Vanadinite Mine.  On the Ready Pay Gulch - Percha Box Loop Trail map (image right) the location of the mine is shown by a green star.  The arrow on the Geologic Map detail shows the location of the mine in relation to various geologic units.

A number of minerals were taken from the mine,including; Arsenatian Vanadintie, Calcite, Cerussite, Descloizite, Fluorite, Galena, Heulandite, Melanotekite, Mimetite, Quartz, Vanadinite, and Wulfenite (these links will take you to mindat.org).  The Black Range Rag blog - The Natural Observer - has several posts about minerals mined in the Black Range; including Fluorite, Vanadinite, Wulfenite, Quartz, and Calcite - all of which were mined at this facility.

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 Vavadinite, the Hillsboro Rock Shop (Packwasher) has photographs of mineral from this mine on its site (referred to as the Bobbee De Claim).

The main shaft at the site is covered partially by boards from the mine frame (see photographs above and below - 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 right) 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.
