New discovery: very aerial group of Chalcocite crystals, huge for the species, between platy and tabular, very sharp, with a pseudo-hexagonal outline and great luster.
This specimen, of high quality for the species, comes from new workings in the M'Passa area where a group of small mines used to produce, in their glorious past, specimens with large sharp crystals. With the closure of the workings in the 1980s, that glory was lost, although fortunately it has now returned with specimens as magnificent as those and, moreover, with a great variety of crystallographic habits. This specimen has been published on the Mineralogical Record´s web page, in the 'What's New' section, report 61, August 30, 2021 edition, page 10
M'Passa Mines, Mindouli District, Pool Department Republic of the Congo (2021)
Specimen size: 6.6 × 5 × 1.2 cm = 2.60” × 1.97” × 0.47”
