RAPAPORT... Stellar Diamonds provided an update on its  bulk sampling program from the Tongo kimberlite dyke project in eastern Sierra Leone. The junior mining company processed  566 tons of kimberlite and granite combined, which resulted in the recovery of 371.45 carats,  for a diluted diamond grade of 65 carats per hundred tons (cpht). Taking into consideration the dilution though, the in-situ grade of the kimberlite for the processing remained at 109cpht. Stellar will re-crush some of the bulk sample, which was expected to result in further diamond recovery.

The diamond quality is considered to be excellent, with 90 percent being classified as gem quality. Nine stones were greater than 1-carat and seven stones were more than  2-carat  with the largest diamond to date being 3.15-carat. When a larger diamond parcel has been produced, Stellar will export the stones for establishing a valuation.

Karl Smithson, Stellar's chief executive, noted, ''The latest results from bulk sampling of dyke 1 at Tongo continue to prove highly encouraging. The in-situ grade of the kimberlite remains high at 109 cpht and the diamond quality is excellent. The processing plant is now running at close to optimal capacity and we are now approximately 30 percent through the sampling program with 566 tons of the planned 2,000 tons having been processed.''

The objective of the current program is to identify an initial inferred resource statement for Tongo. Based upon the assumed grade and  recovered diamond quality so far, the company believes that Tongo has the potential to deliver substantial value for shareholders.
