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.

Minas da Panasqueira


 

 

 

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.

The Fluorite, with a lilac-blue color, has grown partially following the forms of the Quartz, Topaz and Arsenopyrite crystals where it is covering them. The upper levels of Panasqueira are currently offering surprising and pleasant novelties, with samples that are very different from what has been known from this mine.
The Fluorite and the Topaz have been analyzed and we’ll send a copy of both analysis to the buyer.
