STAR - ORION SOUTH DIAMOND PROJECT

PILOT CORE & SONIC DRILLING COMPLETED

George H. Read, P. Geo., Senior Vice Presi dent Exploration and Development of Star Diamond Corporation (“Star

Diamond” or the “Corporation”) is pleased to announce that Rio Tinto Exploration Canada Inc. (“RTEC”) have

completed an HQ core drilling and sonic program, consisting of 3 core drill holes at Star and 23 holes at Orion

South (Table 1), and some 2,326.5 metres of sonic overburden drilling from 3 holes at Star and 21 holes at Orion

South (Table 2). In total 3,976.52 metres of kimberlite were intersected from 7,056.00 metres of core drilling. This

core drilling is required to accurately document the internal stratigraphy of the Star and Orion South Kimberlites

in preparation for RTEC’s bulk sampling with the Trench Cutter Sampling Rig. The core drilling program was

conducted by George Downing E state Drilling Ltd. of Grenville, Quebec. RTEC geologists are responsible for the

supervision of the drilling program and subsequent core logging. S tar Diamond geologists also conduct

independent logging of the core. In conjunction with this diamond drill program, geotechnical investigations of

the overburden are currently being conducted, at the same locations as the core drilling, by Boart Longyear Inc.,

utilizing a Sonic drill rig. Detailed geotechnical logging of the core collected by the Sonic rig is b eing completed by

Clifton Associates Ltd.

Senior Vice President Exploration and Development, George Read, states: “This core and geotechnical dri lling

program is an important precursor to RTEC’s bulk sampling with the Trench Cutter Sampling Rig scheduled to

commence once the warmer weather arrives . The selected locations of these core holes on the Star and Orion

South Kimberlites will act as pilot holes for the upcoming program . Core hole FALCOSG008 interescted one of the

feeder vents of the Orion South Kimberlite and drilled 449.48 metres of kimberlite before terminating at a total

depth of 562.37 metres below surface in dolomite country rock. This deep intersection of kimberlite is consistent

with the Orion South geological model prepared by Star Diamond geologists.”
