The move will bring Petra into line with Tanzania's mining legislation which sees the government granted a 16% free carried interest in all major mines in the country. Williamson is Tanzania's only major diamond mine.

Petra Diamonds and the government of Tanzania will each give up a proportionate amount of their current stakes to grant the 16% free carried interest. Petra's stake will thus reduce from 75% to 63%, with Tanzania's stake increasing from 25% to 37%, Duffy said.
