13hbmdis ((BORNITE, QUARTZ, PYRITE)), $10 MINIMUM BID, Kelly Mine, Butte, Silver Bow County, Montana, 11 x 6.5 x 6 cm, Cabinet, | |
After the Butte show I bought several flats of Montana minerals from a retired digger. These have not been cleaned. Here is an iridescent blue Bornite from Butte. No crystals just massive Bornite with Calcite and Quartz mix. The digger had this labeled Kelly Mine, Butte. I was not able to verify on mindat if this is correct as a locality. |
