Peregrine Reports New Microdiamond Results For CH-7 Kimberlite At Chidliak

February 27, 2012 PDF version
Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) (TSX:PGD) is pleased to report new microdiamond results from samples of drill core from the CH-7 kimberlite that continue to demonstrate coarse diamond size distributions. CH-7 is located on the 8,580 square kilometre Chidliak project (“Chidliak” or “the Project”) on Baffin Island, Nunavut, Canada. These sample results are from previously untested zones in the south lobe and northwest portion of CH-7.

The following table summarizes caustic fusion diamond results from the CH-7 kimberlite. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories (“the SRC”).

Of special note is a 175.4 kg sample from the bottom of drill hole #7 in the northwest portion of CH-7 that returned 546 diamonds larger than the 0.106 mm sieve size including 12 diamonds larger than the 0.85 mm sieve size weighing a total of 0.668 carats. The largest diamond in the sample was described by SRC as a 0.51 carat, off-white octahedron.

Mr. Brooke Clements, President of Peregrine, said “Today’s results from almost 600 kilograms of drill core reflect the consistently strong diamond content and coarse diamond size distribution we are seeing in samples from all across CH-7. All of the diamond results to date show that this kimberlite could have a grade of at least one carat per tonne, which reinforces our belief that Chidliak will be Baffin Island’s first diamond mine.”

Discovered in 2009 by prospecting, CH-7 is one of the six kimberlites considered to have economic potential within the Southern Focus Area of Chidliak, an area with a radius of only eight kilometres. To date, two vertical and 12 inclined core holes for a total of 2,009 metres and two reverse circulation (“RC”) holes for a total of 77 metres, have been drilled at CH-7. The drill data and interpretation of geophysical data indicate that CH-7 has a surface area of approximately one hectare and is open at depth.

The current geological interpretation of CH-7, based on detailed core logging, suggests that there are distinct northern and southern lobes. The northern lobe consists of coarse olivine and indicator mineral-rich, coherent kimberlite (K
