ERT26AN4: New discovery: very aerial floater group of platy Chalcocite crystals with a very sharp pseudo-hexagonal outline, very lustrous, and with fine coatings of Malachite.
The specimen comes from new workings in the M'Passa area where a group of small mines yielded, in a glorious past, specimens with large sharp crystals. With the closure of the workings 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.
