Libethenite, Malachite
Tilwezembe mine, Mutshatsha, Lualaba, DR Congo
Libethenite with green malachite on matrix.
The mineral build huge crystals at the deposit, up to 15 mm on edge.
This type of specimens where collected by the late J. M. Pendeville in the very late 90's. He only collected a few of these. No idea how common the mineral is at the deposit. Never saw much of these anyway.
