Short summary
This paper describes the characterization of a new mineral from the Oumlil mine in the Bou Azzer cobalt mining district in Morocco. This mining district is one of the world's largest producers of the important element cobalt. This study on the new mineral halilsarpite provides useful information on the results of chemical weathering processes on the primary arsenide minerals at the mine.
