The now defunct Urad mine was a small scale Molybdenum mine on the east slope of the Continental Divide in Colorado (just up the hill from the Henderson mine). Very few specimens from this mine were ever recovered and made available on the market. This specimen is a good example of the well known hydrated iron molybdate, Ferrimolybdite, featuring powder yellow patches of crude crystals on matrix. Ferrimolybdite typically forms as an alteration of Molybdenite in these hydrothermal veins along the Colorado Mineral Belt. The specimen was collected in the mid 1970's, and is one of the few I have seen from the Urad mine. It is also one of the few specimens from the Urad mine from the well known Richard A. Kosnar Colorado collection.
