Karl Smithson, Chief Executive Officer, commented:

"Stellar's focus during the past six months has been on the generation of maiden resource statements for our key kimberlite projects at Droujba and Tongo in Guinea and Sierra Leone respectively. I am pleased to report that excellent progress has been made during this report period. Resource drilling has been completed at both projects and at Tongo we have also completed the bulk sampling evaluation of the 2.5km long Dyke 1 kimberlite. This returned a highly encouraging +1mm in-situ grade of 121 carats per hundred tonnes ("cpht") and a diamond value of $185 per carat. At Droujba the collection of four bulk samples weighing a total of 940 tonnes has been completed as has construction and commissioning of the processing plant to treat these samples.

"We have also been pleased to read of the planned IPO of the Koidu diamond mine on the Hong Kong stock exchange, as this is situated adjacent to our Kono project and will help raise awareness of the potential value within our Kono permits.

"We remain on track to achieve our stated objective of delivering the resource statements in the first quarter of 2012 and I look forward to updating shareholders as we progress to these key milestones for the Company."
