Copper.
NA14V4: Copper
Arborescent growth of slightly defined crystals of native Copper with small grains of massive Quartz. It is from a new locality for Morocco, in which only this kind of samples of Copper are known. We hope that it will give agreeable surprises in the next future.

Copper (neoformed).
EV46AF7: Copper (neoformed)
Aggregate of deformed and rounded crystals. A curious growth that is the result of the removal of copper during the mining in which the copper recrystallizes sometimes acquiring the shapes of the objects and machines it has grown on.
