Diamonds are forever, says Petra

11 august 2009

Southern African diamond prospector Petra Diamonds expects prices to continue rising as it expands its new Tanzania mine, The East African reported.
The firm spent $10 million to purchase a 75 per cent interest in Mwadui Williamson Diamonds in November 2008.
It sees gradual recovery in Tanzania diamond mining and expects to produce 500,000 carats in the coming years from the current 200,000 carats per year.
Petra Diamonds corporate communications manager Cathy Roberts told The EastAfrican from London that the acquisition of the Tanzania mine was in line with the group’s diversification programme and global expansion.
She said the firm is focused on establishing new operating parameters and so far initial recoveries, grade and diamond prices achieved on tender have all been encouraging.
The Williamson mine is an open pit diamond mine at Mwadui in Shinyanga.
Standing at 146 hectares, Williamson is a large kimberlite pipe that has been operated continuously as an open pit mine for almost 70 years.
In that period, the mine has produced over 20 million carats.
The mine regularly produces large, high-quality stones and is a source of rare, fancy pink diamonds.
Petra Diamonds chief executive Johan Dippenaar said the firm plans to initially operate Williamson at a rate of 200,000 carats a year before it embarks on further expansion plans to capitalise on the economies of scale offered by the large Mwadui kimberlite deposit.
Indications are the introduction of the new technology could increase throughput to above 7.5 million tonnes per annum from the current 3.2 million tonnes.
