The place in question is an entirely landlocked, mountainous, somewhat mysterious-seeming country which boasts a long mining history and has a secure reputation for turning out world-class specimens of--oh, let's see--metallic species (andorite, pyrarygrite, stannite, franckeite, cylindrite), other primary ores (cassiterite, ferberite), and glamorous phosphates (phosphophyl-lite, paravauxite, vivianite, ludlamite) such as we have long admired and lusted after.
Among the generous number of photographs there are photomicrographs, including SEM images, imparting exquisite close-ups of oriented inclusions, striations, faden lines, jamesonite rings and cylindrite cylinders, and all manner of other micropheomena.
It is the type locality for five mineral species (vauxite, metavauxite, paravauxite, sigloite and jeanbandyite) and has also produced some of the world's best specimens of stannite, cylindrite, monazite, bismoclite, and other species.

The sulfides and Sulfosalts are very well represented, most notably arsenopyrite, bismuthinite, bournonite, cylindrite, franckeite, pyrargyrite, pyrite, stannite, stibnite, teallite, and wurtzite Among the oxides, cassiterite and quartz are most important and siderite is the most important carbonate.
Associated minerals are: franckeite, cylindrite, hocartite, rhodostannite and sphalerite.
Composite structures of members of the cylindrite group are formed of two kinds of layers, pseudo-hexagonal (H) and pseudo-tetragonal (Q).
