Chalcocite with Malachite.
ERV37AN4: Chalcocite with Malachite
New discovery: very aerial floater group of platy Chalcocite crystals with a sharp pseudo-hexagonal outline and with fine coatings of Malachite.

With the cessation of exploitation in the 1980s that glory was lost, but fortunately it has now returned with specimens as magnificent as those and, moreover, with a great variety of crystallographic habits.
