The Unnamed is a titanium, metal, uranium, zinc, zirconium, niobium (columbium), copper, and lead mine located in Hill county, Montana.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): CONCENTRATE OF THE PORPHYRY INDICATES A POTENTIAL SOURCE OF ZIRCONIUM, NIOBIUM (COLUMBIUM), URANIUM, AND TITANIUM. LOCAL CONCENTRATIONS OF BIOTITE LED TO EXPLORATION FOR VERMICULITE IN THE 1920'S WITH UNFAVORABLE RESULTS, FOR THE MATERIAL IS ALTERED BIOTITE RATHER THAN VERMICULITE. ; GEOL.DESC: ALSO CONTAINS SULFUR: DISSIMENATED MINERALS
Comment (Deposit): THE SYNONYM NAME IS TAKEN FROM USGS MAP I-237
Comment (Location): LOCATION PLOTTED IS NAMED "VERMICULITE PROSPECT" ON USGS MAP I-237

Comment (Geology): PORPHYRITIC POSTASSIC SYENITE AT THE HEAD OF BIG SANDY CREEK CONTAINS A SUBSTANTIAL QUANTITY OF DISSEMINATED SULFIDES, MOSTLY PYRITE AND PYRRHOTITE, IN AN AREA OF ABOUT 1000 TO 1500 FEET. THIS "PORPHYRY TYPE" SULFIDE DEPOSIT CONTAINS MINOR AMOUNTS OF COPPER, LEAD, AND ZINC, AND IS POTENTIALLY A SOURCE OF SULFUR. THE TYPICAL ROCK CONTAINS 2-6% OF SULFIDES BY WEIGHT BUT LOCALLY THE ROCK CONTAINS MORE THAN THIS AMOUNT. A GREAT NUMBER OF SILICATE-CARBONATE-SULFIDE PEGMATITES AND VEINS ARE SCATTERED THROUGHOUT THE PORPHYRY AND IN ADJOINING MONZONITE AND SKONKINITE, AND THEY ARE CHARACTERIZED BY A HIGHER PROPORTION OF GALENA AND CHALCOPYRITE TO IRON SULFIDES, THAN CONTAINED IN THE PORPHYRY, AND A HIGHER PROPORTION OF PYRRHOTITE TO PYRITE. THE CARBONATE-RICH FACIES (CARBONATITES) LOCALLY CONTAINS RARE-EARTH-BEARING CARBONATE MINERALS. ACCESSORY MINERALS IN THE PORPHYRITIC SYENITE INCLUDE ZIRCON, APATITE, BIOTITE, PERKOVSKITE, AND PYROCHLORE. IN ADDITION TO THE SULFIDES, A HEAVY-MINERAL

Principal Gold Districts of Montana
In Montana, 54 mining districts have each have produced more than 10,000 ounces of gold. The largest producers are Butte, Helena, Marysville, and Virginia City, each having produced more than one million ounces. Twenty seven other districts are each credited with between 100,000 and one million ounces of gold production. Read more: Principal Gold Districts of Montana.
