KONO

Petra reported that Kono operations produced a total of 2,923 carats during the period ended June 30, 2009. A total of 4,213 carats of diamonds have been produced from trial mining at Kono to date. Of these, the Pol-K shaft has yielded 3,209 carats and the Bardu shaft 867 carats. The balance came from other kimberlites that were tested, but have not yet been developed further.In May 2009, Petra made a decision with their joint venture partner Stellar to place the Kono kimberlite fissure project on temporary care and maintenance. The Kono project is currently sole-funded by Stellar and is at an advanced stage of exploration, with underground trial mining having been undertaken at the Pol-K and Bardu kimberlites.

Searchgold Resources reported that Mandala project entered commercial production in April 2009. Over 7,600 carats produced to date at an average grade of 44 carats per hundred tons, including gem and non-gem diamonds of: 31.33, 12.94, 10.93, 5.79, 4.92, 4.66, 4.22, 3.98 and 3.7 carats in size. Also, Kono underground trial mining produces 4,400 carats to date, the three largest diamonds being 11.95, 11.40 and 10.55 carats in size.

Petra Diamonds announces that the Kono kimberlite fissure project in Sierra Leone, a joint venture with Stellar Diamonds Limited, has been placed on temporary care and maintenance. This decision will be reviewed by both parties when the rough diamond market improves sufficiently to achieve a more reasonable sales value for the Kono trial mining production.
