Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) is very pleased to report the discovery of large diamonds and a coarse diamond size distribution in representative drill core samples collected from the CH-6 kimberlite located on the 9,800 square kilometre Chidliak project (“Chidliak”), Baffin Island, Nunavut, Canada. A 398.8 kilogram sample collected from CH-6 yielded 2,730 diamonds larger than the 0.075 mm sieve size, including 131 diamonds larger than the 0.600 mm sieve size. The largest diamond recovered from the sample was a 0.62 carat white, transparent aggregate. The CH-5 kimberlite was also determined to be diamondiferous with a 423.7 kilogram surface sample yielding 49 diamonds larger than the 0.075 mm sieve size.

The following table summarizes caustic fusion diamond results for the CH-6 and CH-5 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories (“the SRC”).
