Peregrine Diamonds Ltd.: Peregrine Diamonds Ltd.: 0.64 Carat Diamond Recovered From CH-7 Kimberlite Surface Sample at Chidliak,

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 5, 2009) - Peregrine Diamonds Ltd. ("Peregrine" or "the Company") (TSX:PGD) 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").

(i) The diamond content of the sample as determined by caustic dissolution
 may not be representative of the overall diamond content of the CH-7
 kimberlite due to a number of factors including the limited area of the
 kimberlite from which the surface sample was collected and the
 relatively small size of the sample.

Brooke Clements, President of Peregrine stated, "The coarse diamond size distribution indicated at CH-7 is another example of the excellent diamond potential at Chidliak. We have now received diamond results for eight of the 16 kimberlites discovered to date at Chidliak, and all eight are diamondiferous with three of these, CH-1, CH-6 and CH-7 having diamond contents and coarse diamond size distributions that are consistent with economic potential. Planning is underway for the 2010 exploration programme, which is expected to commence next April and will include multiple drill rigs, an expanded high resolution airborne geophysical survey and more prospecting for kimberlites exposed at surface."

CH-7 DIAMONDS AND CHARACTERISTICS OF THE CH-7, CH-4 AND CH-8 KIMBERLITES

Four of the eleven diamonds larger than the 0.600 mm sieve size from the 220.9 kilogram CH-7 sample were classified by the SRC as having a white colour and seven were described as off-white. The two diamonds from CH-7 larger than the 1.18 mm sieve size were described as a 0.64 carat off-white, transluscent octahedroid and a 0.06 carat off-white, transluscent distorted crystal.

A photograph of the 0.64 carat diamond and other images from CH-7 are available on Peregrine's web-site at [ http://www.pdiam.com/i/pdf/chidliak274.pdf ].

The CH-7 kimberlite was discovered while prospecting a geophysical anomaly with an estimated surface expression of one hectare as reported on August 6, 2009. The kimberlite sample was collected from subcrop and outcrop over an area of approximately 5 m by 30 m and consisted of massive magmatic kimberlite with 30 to 50 percent olivine macrocrysts up to ten millimetres in size, abundant kimberlite indicator minerals and common mantle xenoliths. In addition, while completing the ground geophysical survey over CH-7, kimberlite float was discovered at two localities associated with geophysical anomalies 400 metres northwest and 400 metres north of the kimberlite.

Discovery of the CH-4 and CH-8 kimberlites was reported on July 16 and August 6, 2009 respectively. The CH-4 kimberlite was discovered by drilling two angle holes across a geophysical anomaly with an estimated surface expression of two hectares as determined by ground geophysics and the 201.6 kilogram sample was derived from both holes. The sample consisted of moderately macrocrystic magmatic kimberlite with 25 to 30 percent olivine macrocrysts up to seven millimetres in size. The 187.9 kilogram sample of CH-8 was collected from cobbles and boulders at the southern edge of an airborne geophysical anomaly with an estimated surface expression of one hectare. The CH-8 sample consisted of magmatic kimberlite with 10 to 15 percent olivine macrocrysts up to ten millimetres in size.

The SRC is an independent laboratory that is accredited by the Standards Council of Canada to the ISO/IEC Guide 25 standard for diamond recovery by caustic fusion. The kimberlite samples were collected, sealed in secure containers and shipped to the SRC under strict chain of custody protocols supervised by senior Peregrine personnel.

Peregrine is the operator of the 2009 Chidliak exploration programme which is being fully funded by BHP Billiton. As announced on November 24, 2008, BHP Billiton has elected to exercise its earn-in rights for Chidliak and, under the terms of the earn-in agreement, must incur a total of $22.3 million dollars in exploration expenditures in order to earn a 51% interest in Chidliak.
