The current lime treatment of the uncontrolled AMD has resulted in the deposition of sludge in the first receptor dam within the Tweelopiespruit, part of the Crocodile River System and Limpopo Catchment.Â This dam, the Hippo Dam, is outside mine property, located within the Krugersdorp Game Reserve.Â The sludge contains toxic and radioactive heavy metals.

On 8 May 2010, the water sample taken from this part of the Tweelopiespruit had a pH of 2 as acidic as lemon juice! In contrast, a stream a few km away with frogs and signs of a visiting otter, had a pH of 6.5.
