Cooke Tailings Dam

The Cooke Tailings Dam was first established in 1976. Since then it has been receiving slimes from material mined from the Cooke 1, 2 and 3 shafts.  These shafts exploit the Elsburg and Kimberley reefs of the Witwatersrand Supergroup.  These reefs have demonstrated the greatest economic importance and are associated with the highest U3O8 and Au grades.
