The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite.
