Pontgibaud is in the Massif Central on the banks of the Sioule river.

The belts of ore extend for about 10 kilometres (6.2 mi) north-south parallel to the course of the Sioule on both sides of  Pontgibaud.

The silver galena veins are embedded in gneissic rock.

The different veins of ore at Pranal, Barbecot, Roure, Les Rosiers, La Miouse and Villevieille are mainly oriented in a north-south direction.

The ores are encased in migmatites from the base of the Combrailles.

The deposits include diverse secondary minerals such as arsenopyrite, anglesite, baryte, bournonite, cerussite, chalcopyrite, freibergite, galena, mimetite, pyrite, pyromorphite, quartz, semseyite, sphalerite, stannite, tetrahedrite and wulfenite.

Many European museum hold samples of these minerals, collected from the Pontgibaud mines by 19th century mineralogists.
