Mark Connolly- The wolf of west Africa, page-25

'Randgold mines also in Mali, Ivory Coast and the Republic of Congo, where it has been faced with regulatory risk, a factor that Barrick's Africa unit Acacia Mining has to deal with in Tanzania.'

This could be why ORR can get the project to 100% for peanuts, (transaction to be completed)...

'Since March 2017, when the ban on concentrates came into effect, the Barrick’s unit has faced a series of accusations, including tax evasion and illegal operations, which prompted authorities to question staff and even block one of the firm’s senior executives from leaving the country in one occasion.'

Just my opinion, DYOR.
