Group of aesthetic cube-octahedral galena crystals, defined faces and edges, and with a better quality than usual for the locality. They are disposed on a matrix covered by brilliant quartz crystals. Accompanied by aggregates of honey color sphalerite complex crystals. With pyrite and flattened twinned marcasite.
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.
Elongated baryte crystals with very well defined faces and edges, transparent, very bright, with a brownish-yellow color and with darker selective micro-inclusions on some of the faces. On a pyrite matrix with marcasite twins, orange micro-siderite and quartz crystals.

A very rich group of cube-octahedral galena crystals, brilliant, nice luster, defined faces and edges, and with a better quality than usual for the locality. They are disposed on a matrix covered by brilliant quartz crystals and small honey color sphalerite. Accompanied by aggregates of golden pyrite crystals, bright and sharp, flattened brilliant marcasite and chalcopyrite.

Fine quality specimen that shows aggregates of tabular crystals of baryte, with a slight bluish tone, brilliant and with defined faces and edges. Accompanied by several marcasite crystals showing various twins, such as "cockscomb", as aggregates or very aesthetic individual crystals. On a quartz crystal matrix.

Huge size parallel growth of tabular crystals of barite, very sharp and with very well defined faces and edges. They are translucent and very bright and have flattened crystals of marcasite showing the twin known as "cockscomb".

Rich group of galena cube-octahedral to octahedral crystals, some of them complex, with natural luster, defined faces and edges, and with a better quality than usual for the locality. They are disposed on a matrix covered by small and brilliant quartz crystals. Accompanied by several aggregates of golden pyrite sharp crystals, brilliant, with chalcopyrite and tabular baryte. Really excellent specimen.

In this huge size specimen we observe groups of tabular lenticular aggregates of barite with a delicate reddish tones, along with gray galena that has been almost completely substituted and covered by nice cerussite crystals. Taking a look under the microscope, cerussite shows long striated prisms terminated by pyramidal faces. Also note several cyclic star twins, well defined and spectacular. Different specimens from Mibladen.
The large mine of Les O is mined under the town of Mibladen. It has been worked during generations of miners in search of specimens, usually galena cerussite, barite and some wulfenite. Few weeks before my visit in February 2013 were found some mineralized veins and vugs with the specimens we offer. When those cavities were formed they had been filled by cube octahedral crystals of galena and barite. Due to the hydrothermal fluids galena was partially or totally corroded to favor the formation of cerussite.
As exceptional as rare specimen of smithsonita from shaft 9 in Toussit. A matrix with galena is partially covered by numerous sharp rhombohedral smithsonite crystals, delicious bluish color, transparent to translucent, forming aggregates, very showy. They accompanied by cerussite crystals very rich in faces and transparent. Good size and fine quality for a difficult piece to be seen nowadays.
An unusual specimen from this Moroccan mining area. Globular aggregates of crystaline conichalcite with its classic green color, partially covering cavities of the matrix. To give a unique touch of quality to this sample, cavities are covered with bright, water-clear calcite crystals, many of them doubly terminated, and including or covering the conichalcite species. An excellent and brilliant specimen.
First appointment for this Moroccan locality. This lead, iron and rich copper sulfate has been analyzed by SEM-EDS, we will send results to the buyer. Beaverite-(Cu) forms yellow earthy masses formed by lenticular crystals. It is accompanied by fibrous malachite crystals and azurite crystal aggregates. In the matrix we have observed the presence of cerussite. Only the combination of colors and species in this sample is aesthetic itself.

Excellent specimen of galena that shows a group of sharp cubic crystals, brilliant, interpenetrated and which are peppered by small crystals of honey color sphalerite. Partially covered by sharp, brilliant quartz crystals and minor calcite. This deposit has been operated by several french compagnies from 1923 to 1960. A quality specimen for this Moroccan locality.
Excelent group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Main crystals size and thickness are remarkable. They are disposed very aerial and isolated on a lenticular baryte matrix. The presence of this baryte matrix is highly appreciated by collectors and gives to the specimen a special aesthetics.
Spectacular specimen with a very good size formed by several vanadinite crystals, with an intense red color and translucent. Very aerial disposed on a rocky matrix. Very displayable and unusual specimen.
Groups of pyromorphite crystals (analyzed) which are disposed on a matrix of goethite. The green yellowish color is very intense, exceptional brilliance, translucent to transparent. They show defined hexagonal prisms truncated by the pinacoid. Under magnifying glass transparency we can be seen perfectly. A nice miniature.
They come from a Moroccan locality that once was known by the presence of pyromorphite, but not with this quality and less represented in collections. Few specimens have been presented at Sainte-Marie-aux-Mines 2015.

Groups of pyromorphite crystals (analyzed), some individualized, which are disposed, with a very aesthetic contrast on a matrix of goethite. The yellowish green color is very intense, exceptional brilliance, translucent to transparent. They show defined hexagonal prisms truncated by the pinacoid, some of them insinuate the hexagonal dipyramid faces. Under magnifying glass transparency we can be seen perfectly.

A rich group of azurite crystals partially replaced by malachite. Azurite crystals show tabular and lenticular shape forming rosettes, with an intense blue color. Malachite shows the shapes of the crystals of azurite those has been partially replaced and fibrous to acicular crystals with a delicate velvety aspect very aesthetic.
