Stellar Diamonds plc is a London (AIM:STEL) listed diamond mining and exploration company that is focussed on the renowned, yet under-developed, diamond region of West Africa. The Company has two alluvial projects in production in Guinea, Mandala and Bomboko, as well as 100% rights over four high-grade kimberlite projects in Sierra Leone and Guinea that are at various stages of development from drilling through bulk sampling to trial mining.

At Mandala production has exceeded 106,000 carats (to end December 2010) and generated sales of $3.2 million since mining commenced in mid-2009. Trial mining is ongoing at the Bomboko project where over 5,100 carats have been produced as part of an evaluation programme.

The kimberlite portfolio is comprised of the Kono and Tongo projects in Sierra Leone and the Droujba and Bouro projects in Guinea.

At Kono underground trial mining has yielded over 4,200 carats of diamonds, however the project was placed on care and maintenance in mid -2009 during the economic crisis.

Bulk sampling is currently ongoing at Tongo where diamond grades of between 100cpht and 380cpht were yielded from previous sampling exercises. A 1,000 to 2,000 carat sample is currently being sampled to determine diamond grade and value of this kimberlite.

Stellar is currently drilling the Droujba kimberlite pipe. The programme is intended to model the pipe to depth as well as assay selected kimberlite core for microdiamond analysis and macrodiamond grade forecasting.

The Bouro project is located in proximity to the Mandala diamond mine. Previous testing yielded grades of up to 500cpht for the Bouro North kimberlite. Stellar is planning to collect and process a bulk sample from this kimberlite in 2011.
