RARE FLUORITE, from the Deer Trail Mine, Utah #FLU02

Description

DEER TRAIL MINE, UTAH FLUORITE
The Deer Trail Mine near Marysvale, Utah was opened in 1878 for silver, gold, lead, zinc etc. with a great deal of the gangue material being fluorite and quartz. The fluorite usually comes in various shades of seafoam green and is most often in and coated with a white quartz. Small prismatic quartz crystals are in evidence and a fine drusy quartz crust coats the fluorite, sometimes forming casts. The fluorite crystals appear to be in the form of dodecahedrons modified by the cube per the detailed description and illustrations in a great MINDAT Discussion Group from 2017. The specimens with or without the quartz crust are often very attractive and many have been treated with acid to remove most of the quartz to reveal the
green color. They are beautifully fluorescent (best under LW though almost as bright under MW) and are really BLUE with little trace of violet. Only a few specimens are seen on the market today and they are usually quite expensive.
The detailed locality is Deer Trail Mine, Mount Baldy Mining District, Cottonwood Creek, Piute County, Utah. Since a major closure in 1985 numerous companies have conducted feasibility studies without taking much action but another company (in 2020) has invested in a search for a suspected porphyry copper/molybdenum deposit at great depth. They have done geological mapping, core testing, seismic detection, airborne magnetic surveys, etc and may reopen this historic mine for different ore.
