Remaining pit water, meanwhile, is being used for beneficiation plant processing, negating raw water needs from the Mokolo Dam, its normal source, according to company officials.

Rain amounts received in March, however, had a peak downpour of 230 mm daily, exceeding the 1:50 year flood designs, leading to pit bottom flooding. Water and flood controls, however, enabled operations to normalize.
