"Sibusiso Mkhize was given bail of USD 200," prosecution spokeswoman Natasha Ramkisson told AFP yesterday.
Lawyers for his co-accused, a Mozambican man, abandoned his bail application after it turned out that the suspect was an illegal immigrant.
The two men in their early 20s were arrested in possession of the kilogramme (2.2 pounds) of uranium while allegedly trying to sell it in the southeastern coastal city of Durban on November 14, officials said.
Investigators have since established the sample was worth only USD 80.
It said the sample was harmless, refusing to speculate on the origins.
Uranium trafficking is rare, but the seizure raised fears over the illicit trade in enriched materials that could be used in dirty bombs.
According to the test results seen by AFP the uranium is 0.38 per cent made up of the U-235 isotope, which is split in a fission reaction.
That level is well below the average 0.7 per cent U-235 found in natural uranium and the 90 per cent level needed to be considered weapons grade.
The two suspects were ordered back to court on January 29.
