About the Mothae Project

The Mothae Diamond Project in Lesotho is a joint venture between Lucara (65%) and Motapa (35%) which will enter a trial mining stage following the recent completion of a highly successful bulk sampling program. The Mothae kimberlite is an 8.8 hectare pipe located 6.5 kilometers northwest of the Letseng diamond mine.

Motapa identified Mothae as a large, low-grade kimberlite with potential to contain a population of large Type IIa diamonds and secured a 24.7 square kilometer prospecting license in 2006. Type IIa diamonds provide a high proportion of the world's highest value stones on account of their exceptional color clarity which is ascribed to having no detectable nitrogen within the diamond crystal structure. Type IIa diamonds also typically have a coarse size distribution and can be present as very large stones. The presence of a population of Type IIa diamonds in any kimberlite greatly enhances its economic potential.

The partners have recently completed a 100,000 tonne bulk sample of the Mothae kimberlite and diamond recovery results to date confirm the presence of a coarse stone size distribution and the presence of a significant population of Type IIa diamonds. To date, 5 diamonds greater than 20 carats, 13 diamonds greater than 10 carats and 63 diamonds greater than 5 carats have been recovered. A total of 8,886 diamonds were recovered during the two phase bulk sampling program, returning 3,867 carats, an average stone size of 0.44 carats and a grade of 4.70 carats per hundred dry tonnes of material mined to date.

The sampling program is being carried out under the supervision of Dr. Tom Nowicki of Mineral Services Canada, a Qualified Person in terms of NI 43-101.
