The rocky dome of the Silberberg drops steeply to the north by a good 550 metres forming one of the highest mountain faces in the Feldberg region.

The forested northern mountainside is divided by cirque-like niches and craggy ridges that are like arêtes in places.

Also present here, are several vein-line porphyry deposits, which were probably formed towards the end of the Variscan mountain building phase,[2] and amphibolite.

A number of mineral lodes run through the Silberberg with a total length of several kilometres and of medium thickness up to 1.2 metres.

In the western, neighbouring cirque of Zimmerwinkel the Dr. Tholus Brunnen gallery was worked by the Gewerkschaft Finstergrund from 1968 until 1970 in order to extract fluorite and baryte.
