Gold with Pyroxmangite and sulfides plus Quartz

This slabbed specimen is one of the few of its kind that I have seen from this mine. It features patches of "Cloud Gold" which is a speckling of small "dust"-like areas of Gold which are intergrown with white Quartz and associated with Galena, Sphalerite and Chalcopyrite, but the most INTERESTING aspect of this specimen is the fact that it features pink bands of the rare Manganese Silicate, Pyroxmangite! This association of Gold with Pyroxmangite is very rare, and possibly unique to the Sunnyside mine. This specimen was mined in 1966, and comes from the Colorado Gold collection of my father, Richard A. Kosnar.
