Petra Diamonds shares drop

More trouble for diamond miner Petra Diamonds  yesterday after it warned it is heading into financial trouble with its lenders.

Petra has borrowed heavily to expand its operations in the country. The company is now likely to breach its banking covenants at the end of the year, because of the row with the government in Tanzania. As well as strikes at three of its mines in South Africa.

Petra diamonds is known for the size and quality of the diamonds produced at the famous Cullinan mine outside of Pretoria in South Africa.
