The Lengenbach Quarry (LGB) is located in the Binn Valley (Valais, Switzerland) and it is famous among the mineralogist community for its unusual sulfosalt specimens.
These minerals have been highly appreciated in the past and also today, due to various factors: the rarity and the diversity of the mineral species collected, the notable perfection of crystals... and also for its esthetic contrast with the snowy Dolomite matrix.
For nearly 200 years, many mineralogists from Europe have devoted a large number of efforts to study the peculiar mineralization of Lengenbach. Today, the geology of the quarry is known in detail as well as the structure of the crystalline sulfosalts collected there. The systematic studies of the collected minerals have contributed to the Mineralogy with a large number of new minerals never described before. Lengenbach is Type Locality for 28 accepted new minerals, 27 new sulfosalts and 1 new phosphate (2008).
This great scientific search effort has been made possible in large part by the foundation, in the year 1958, of the Lengenbach Working Community (Arbeitsgemeinschaft Lengenbach) which has published a good number of articles, notes, books, etc with Lengenbach as the reference.

Where is the quarry?

The Dolomite deposit of LGB is located in the Binn Valley (other names of this valley are Binntal, Binnatal, Binnathal, Binnenthal), a small valley in the southwest of Switzerland in the Swiss canton of Valais. To its south lies Italy.
To get there you must take the road from Brig to Andermatt, and between Lax and Fiesch you must turnoff direction Ernen and Binn.
From Binn, after the long tunnel, you must get Imfeld. From this small village, close to the Pius restaurant, there is a single road to the quarry but it is closed to the unauthorized motor vehicles traffic. Walking is 30 minutes to the Lengenbach Quarry.
Due to its location and its fully Alpine appeal, 1.660 meters, the mine remains closed from autumn to spring, depending on the snow period. However, the quarry is fenced and the public is only allowed to look for minerals in the dump in front of the quarry.
