Superior Completes Third Hole Through Morin Kimberlite and Continues Diamond Exploration in the Lac Honorat Area, Ville Marie Area, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 7, 2007) - Superior Diamonds Inc. (TSX VENTURE:SUP) ("Superior" or the "Company") has completed drilling its third hole through the Morin kimberlite pipe. The purpose of this hole is to provide a south to north cross section through the upper part of the pipe. The hole was collared 50 metres from the southern edge of the pipe and drilled at a 50 degree angle north. The drilling was terminated at 264 metres due to badly fractured kimberlite located near the northern edge of the pipe. This hole follows the completion of two vertical holes: the first collared 50 metres from the eastern side of the pipe and cutting through 500 metres of crater facies material(1) and the second collared 50 metres from the western side of the pipe and cutting through 141 metres of crater facies material(2).

Logging of the kimberlite material recovered from the first two vertical holes has been completed by Mineral Services Canada Inc. Thirty-three representative samples have been submitted for micro-diamond analysis to SGS Lakefield Research Limited. Additional samples have been collected for petrographic and heavy mineral analysis.

Geophysical orientation surveys completed over the Morin kimberlite pipe(3) have identified geophysical methods and surveys useful in defining kimberlite in the Ville Marie area. As such, ground magnetic surveys are being completed at the heads of the Lac Honorat and Lac D'Argent dispersal trains. Results from these surveys are expected to define kimberlite targets that will better direct Superior's drilling program.

Diamond exploration at the head of the Lac Honorat kimberlite dispersal train continues with grid drilling and ground magnetics. Grid drilling is now focused on the north side of the Laverlochere River after a kimberlite boulder was intersected in overburden and a kimberlite stringer intersected in bedrock in two separate holes north of the river.
