The Lubao kimberlite project consists of 20 PRs covering an area of 7,317 square kilometres in Kasai-Orientale province, historically the largest diamond producing region in the DRC. The geology of the region represents an extension of the Angola Craton, which underlies the rich diamond fields of Lunda Norte Province, in northeast Angola.

Given the highly favourable geological setting and the fact that the area has never been explored using modern exploration techniques, the Company believes that the region is highly prospective for hosting kimberlite pipes.

In 2007, BRC completed a reconnaissance stream sampling program, collecting 817 samples, and commissioned a reconnaissance airborne geophysics survey of 8,792 line kilometres over areas that had produced positive samples. These programs were followed up by close interval stream sampling (198 follow up samples) and detailed airborne geophysical surveys (16 blocks; 538 line kilometres). As a result of this work, 16 targets have so far been identified for further assessment. The Company believes that the presence of indicator minerals and alluvial diamonds in the vicinity of the targets, and away from the main drainage, make these targets of exceptional interest. Drilling is scheduled to commence in the second quarter of 2008.
