The goal of the project was to develop biological and chemical agents that would either kill or sterilize the black population and assassinate political enemies. Among the agents developed were Marburg and Ebola viruses.
Basson is surrounded by cloak and dagger intrigue, as he told Pretoria High court in South Africa that "The local CIA agent in Pretoria threatened me with death on the sidewalk of the American Embassy in Schoeman Street." According to a 2001 article in The New Yorker magazine, the American Embassy in Pretoria was "terribly concerned" that Basson would reveal deep connections between Project Coast and the United States.
In 2013, Basson was found guilty of "unprofessional conduct" by the South African health council.
