Since mining formally ended in 2000, a few remaining miners have concentrated on recovering specimens, and good examples of other sulfides including seligmannite, and also gypsum, have been brought out.
Some of them are covered by tiny seligmannite crystals, yellow orpiment and powdery orange pararealgar.
The arsenic sulfides rest on massive black matrix of mixed sulfides in which lurk microcrystals of the rare mineral seligmannite (PbCuAsS3).

Helga and Horst Geuer (Am Sonnenhang 39, 53639 Konigswinter, Germany) had their usual excellent selection of specimens from Eifel and Lengenbach, the former including brenkite, calciobetafite, cuspidine, jacobsite, jasmundite, nickenichite, perrierite and srebrodolskite, and Lengenbach being represented by some early material from the Novacki Institute, which was also the source of some excellent specimens of marrite, rathite, seligmannite, trechmannite and imhofite, together with a small number of lengenbachite specimens of typical bladed form.
