Peregrine Announces Coarse Diamond Size Distribution in CH-45 Kimberlite and Commences 2011 Chidliak Programme

January 13, 2011 PDF version
Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) is pleased to report a coarse diamond size distribution for a 173.6 kilogram sample of reverse circulation (“RC”) drill cuttings collected from the CH-45 kimberlite on the 9,800 square kilometre Chidliak project (“Chidliak” or “the Project”) on Baffin Island, Nunavut, Canada. The sample was processed by caustic fusion and yielded 158 diamonds larger than the 0.106 mm sieve size, including two diamonds larger than the 0.850 mm sieve size which weigh a total of 0.091 carats. In addition, the CH-33 and CH-37 kimberlites were found to be diamondiferous.

The CH-45 pipe is the seventh kimberlite at the Project displaying characteristics consistent with economic potential in Arctic settings. It is located within the Southern Focus Area, 300 metres northwest of the Discovery exploration camp, and 900 metres south of the CH-7 kimberlite. The Southern Focus Area has an eight kilometre radius and currently hosts six kimberlites with economic potential: CH-1, CH-6, CH-7, CH-31, CH-44 and CH-45.

The following table summarizes caustic fusion diamond results from the CH-45, CH-33 and CH-37 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories (“the SRC”).
