PANASQUEIRA MINE


 

 

 

There is a great mine that is still active within the Iberian peninsular: the mine of Panasqueira in Portugal. The current low price of Wolfram and the competition from other sources means that commercial operation is tough. But for all this, this classic locality has for over 100 years produced, and keeps on producing, fine specimens. These include exceptional specimens of Apatite-(CaF), Ferberite, Arsenopyrite, Siderite, Quartz and numerous other species such as: Chalcopyrite, Sphalerite, Dolomite, Calcite, Mica, Tourmaline, Fluorite, Topaz and Triplite. It has also produced some very rare minerals including Panasqueiraite and Thadeuite. The great feature of these specimens, apart from their quality, is the fact that they almost always combine quite a few mineral species, so the paragenesis has made this mine famous throughout the world.

I started to visit this locality when I was 14 years old, and I have never stopped visiting it since. So I must have been to visit it well over a 100 times. For many years the sale of mineral specimens from the mine was forbidden, as Wolfram was a strategic mineral. So the moments I passed there acquiring specimens could form the basis of quite an exciting book! Over the years I got to know miners, shift managers, administration staff, engineers and geologists. Some were friendly while others were not, but they were all interested in not only the money they could obtain from 'as pedras' ('the rocks' in Portuguese) but also the beauty of the specimens.

Quite a few years ago, and at the same time as Portugal began to change after its entry into the European Union, things began to become easier. However, unfortunately, obtaining good specimens has one again got more difficult, but this time due to the way the mine is worked and the lower grade seams. All that said, I'm still 'trapped' by the beauty of the minerals and the large number of friends I have developed over all those years.

If you want more general and scientific information on this great mine you can get it by following this link. It leads you to a page where we have reproduced text and photos from one of the few publications produced by the mine itself.

We will send the specimen, which comes from the Robert J. Noble collection, in its original Perky box from that collection, which also contains the label, which shows that it was previously in the Bob Sullivan collection.

WWE16CD1: Notable for several reasons. Due to its pedigree, since it belonged to the Natural History Museum of Los Ángeles and was later in the Raúl Sanabria collection, and for the Fluorapatite / Sphalerite association, which is rare in Panasqueira, and for its perfection, without the slightest defect or damage.
An excellent piece, which carries with it a lot of added value.

NE43E7: Look out for this one: it is marvelous. The prismatic Fluorapatite crystals are large, aerial and have a great color that is somewhere between blue and green. That said please note that, as you can see in the detailed photo, there is a significant contact on one of the upper faces of crystals. This is where there used to be some Siderite (I know this as I removed it). When you display this specimen the contact is not visible, but you see it when you hold it in your hands. So the importance you give to this contact will affect your wish to have this one in your collection. For me, given the beauty and quality, the fact that there is a contact (this is not damage) due to the former Siderite is acceptable, especially given that it is very difficult to find such specimens at a reasonable price.

NZ46E6: Very transparent crystals of Quartz. So you can see the well-defined crystals of Arsenopyrite and sprays of Mica inside it. They were trapped in it as the Quartz grew. The Quartz itself is a floater (with a recrystallized base) and has a totally undamaged tip, which is not that common in specimens from Panasqueira given the way they are collected. On the outside there are similar minerals to those inside: Mica and Arsenopyrite.

Stannite with Sphalerite and Arsenopyrite.
 

NQ60F4: A curious and unusual form. The crystals of Sphalerite have such curved edges and faces that they appear to be almost spherical. The Stannite is a fine coating, which makes the Sphalerite appear satin. At the base there are some prismatic, well-developed crystals of Arsenopyrite that make this one seem aerial and esthetic.

NF11X9: Stannite and Chalcopyrite intergrowths. The Stannite is slightly golden dark gray and the Chalcopyrite shows a brass color. The complexity of these growths, the poor definition of crystalline forms and the fact that Stannite also frequently substitutes for Sphalerite, resulted in Stannite having been almost unnoticed at Panasqueira.

Preguiça Mine

Descloizite is a mineral not well known in good quality specimens from the European continent. Even considering that the Preguiça Mine, in Portugal, was known for years for its Descloizite and a wide variety of zinc minerals, the quality of the samples was not especially high because the crystals were too small or not esthetic.
Between 2005 and 2006 groups of collectors from Huelva (Spain) were intensely working that mine and finally found some pockets with specimens of Descloizite of high quality, some of them particularly esthetic (and scarce) stalactitic or columnar and associated with white Calcite.
In our opinion these specimens can be considered as the best Descloizites found in Europe.

Just to be certain, we analyzed them and the analysis proved that they are definitely Descloizite. To be more exact, slightly copper rich Descloizite, but the mineral species is Descloizite. We will send a copy of this analysis to our customers who buy this material.
