Failure of the Merriespruit gold tailings dam in 1994 in South Africa was unusual in that never before had a gold tailings dam in South Africa failed in such a catastrophic fashion. Conventional thinking was that gold tailings would always exhibit dilative characteristics upon loading, primarily because of the method of deposition which allows significant consolidation to occur due to sun drying.

No option to store water within a dry stack facility. A conventional tailings facility, designed to store water, can provide a mining operation with a buffer (e.g. storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water.
