Quarries situated 36 km NW of Erfoud and 9 km E of the village Asselaa. erronously refered to as Lhamda mine.
The hydrothermal fluorite-baryte deposit lies in precambrian-hercynian granites in the northern part of the Jebel Ougnat massiv. It consisted of a 1.500 m long and 2 m wide fluorite vein, which had been exploited til 2003. New exploration works had been envisaged. The fluorite from this locality went to France and to Venezuela to be used in the ceramics industry. Apart from huge fluorite cubed there were also very large blocky baryte crystals up to 25 cm length.
