exploration update

HIGHLIGHTS

• Ongoing grid drilling program has increased the estimated surface area of the priority Se251 kimberlite at the Lulo Diamond Concession to more than 220 hectares. All 17 core holes drilled to date at Se251 have intersected kimberlitic rocks

• First bulk samples of coarse kimberlite breccias from Se251 have been excavated. This bulk sample will be treated through Lucapa’s new 50 tonne per hour Dense Media Separation diamond plant, which remains on target to be completed by the end of September 2013

• 52 diamonds weighing 52.45 carats recovered from the BLK_14 alluvial bulk sample, enhancing expectations of an economic diamond resource from widespread gravels discovered in this area

• First bulk sample extracted from the Se046 kimberlite, which could be the source of the BLK_14 alluvial diamonds
