A large lead and zinc mine, owned by Preussag Metall AG and closed in 1992.

The ores (mainly galena and sphalerite) are included in calcite veins hosted by carboniferous slates.

The Grund mine was formed in 1923 by merging of the older mines Hilfe Gottes mine (western part) and Bergwerkswohlfahrt mine (eastern part).

Located 1.5 km ESE of Bad Grund and about 5 km west of Clausthal-Zellerfeld.
