0.64 Carat Diamond Recovered From CH-7 Kimberlite Surface Sample At Chidliak, Baffin Island, Nunavut

October 5, 2009 PDF version
Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) is very pleased to report the discovery of a 0.64 carat diamond and a coarse diamond size distribution in a surface sample collected from the CH-7 kimberlite on the 9,800 square kilometre Chidliak project (“Chidliak”), Baffin Island, Nunavut, Canada. A 220.9 kilogram sample collected from CH-7 yielded 664 diamonds larger than the 0.075 mm sieve size, including 11 diamonds larger than the 0.600 mm sieve size. The CH-4 and CH-8 kimberlites are also diamondiferous with 201.6 and 187.9 kilogram samples of drill core and surface material respectively yielding 15 and 17 diamonds larger than the 0.075 mm sieve size including one diamond larger than the 0.600 mm sieve size from CH-4.

The following table summarizes caustic fusion diamond results for samples collected from the CH-7, CH-4 and CH-8 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories (“the SRC”).
