Group of cubic galena crystals with an exceptional size for the locality, brilliant and very sharp. They are disposed on an matrix partially covered of small quartz crystals. We can observe pyrite and marcasite on the matrix.
These mines are located approximately 50 km south of Alnif, near the border with Algeria. This area was already mined in medieval age for the extraction of copper. In the 60s of the last century, French companies expanded shafts and mineral extraction.
Large group of prismatic crystals of albite, well defined, beige color and interpenetrating each other. They're accompanied by numerous aggregates of prismatic crystals of epidote, fibrous actinolite and smoky quartz crystals. Highlights small magnetite octahedral crystals those are placed in the cavities of the specimen. They were sold as orthoclase but a recent XRD analysis I have done indicates that it is albite (2/15/2024). Maybe more interesting.
Druse formed by a group of quartz var. amethyst-smoky crystals, showing defined faces and edges, from translucent to transparent. One has a small notch in its upper face. They are disposed on a matrix of feldspar, probably orthoclase, with prismatic crystals of green epidote and fibrous actinolite.

Exceptional color, brightness, cubic predominant crystals with small octahedral faces, orange reflections, gold lights... We have preserved an area with a brown patina of goethite to contrast the gold color. Golden colored coatings could be due to a thin layer of chalcopyrite. A strange and aesthetic specimen. Very unusual.
Probably one of the best galena specimens we are showing in the site. This is formed by a large group of cube-octahedral galena crystals with a remarkable size for the locality and its natural dull luster. Very sharp faces and edges. They are disposed on a matrix with various aggregates of tabular twinned marcasite and, together with crystals disphenoidal chalcopyrite and some pyrite. A more than representative sample for the locality.

Unusual specimen for this Moroccan locality formed by a quartz matrix on which stand numerous groups of sphalerite crystals with a toasted honey tone, translucent and bright. They accompanied by brilliant pyrite crystals and very interesting aggregates of twinned marcasite. A piece almost unique.
