Alyssa heeft een blog geplaatst over het bezoek aan de Bou Azzar Mine.

After the tour we head out to look for interesting cobalt-rich minerals in the vicinity of the mine.  Nearby in Khder quarry we found tiny red crystals of erythrite (Co₃(AsO₄)₂·8H₂O) and roselite (Ca₂(Co,Mg)[AsO₄]₂·H₂O).  This is the type locality for cobaltarthurite. Tony described this mineral and the specimen was collected by Georges. In fact all Moroccan minerals Tony has worked on were collected by Georges.
