SM160NYG: Bornite after Chalcocite
Bornite with bluish metallic tones pseudomorphic after twinned crystals of Chalcocite. The specimen comes from the last find before the definitive closure of open-pit mining here, and this is the first time that collector quality Bornite has appeared at this locality. These specimens has been analyzed and we will send a copy of the analysis to the buyer.
