Peregrine Reports 2.08 Carats of +0.85 mm Diamonds From New 170 kg Ch-6 Sample and Promising Coarse Diamond Size Distributions

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 12, 2009) - Peregrine Diamonds Ltd. ("Peregrine" or "the Company") (TSX:PGD) is pleased to report outstanding new diamond results from the CH-6 kimberlite that support previous results from that kimberlite. In addition, promising coarse diamond size distributions were received from samples of the CH-10 and CH-12 kimberlites. The CH-6, CH-10 and CH-12 kimberlites are situated on the 9,800 square kilometre Chidliak project ("Chidliak"), Baffin Island, Nunavut, Canada. The southwestern corner of Chidliak is located only 60 kilometres from Iqaluit, Nunavut's capital.

On September 21, 2009, the Company reported the discovery of 2.50 carats of +0.85 mm diamonds from a 398.8 kilogram sample of drill core collected from the CH-6 kimberlite. An additional 170.3 kg sample of drill core collected from a magmatic phase of CH-6 ("CH-6C") has returned 2.08 carats of +0.85 mm diamonds. A total of 2,007 diamonds larger than the 0.075 mm sieve size, including 91 diamonds larger than the 0.600 mm sieve size, was recovered from the sample with the two largest diamonds being a 0.420 carat white, translucent aggregate and a 0.361 carat yellow, transparent distorted crystal.

A 111.4 kilogram sample of drill core collected from CH-10 yielded 152 diamonds larger than the 0.075 mm sieve size, including two diamonds larger than the 0.600 mm sieve size. A 251.7 kilogram sample of surface kimberlite collected from CH-12 yielded 270 diamonds larger than the 0.075 mm sieve size, including three diamonds larger than the 0.600 mm sieve size. The CH-9 and CH-11 kimberlites were also determined to be diamondiferous. A 216.8 kilogram surface sample of CH-9 yielded two diamonds, one larger than the 0.075 mm sieve and one larger than the +0.106 sieve size and a 210.0 kilogram surface sample from CH-11 yielded one +0.075 mm stone.

The following table summarizes all caustic fusion diamond results to date from the CH-6 kimberlite together with results from the CH-10 and CH-12 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories ("the SRC").

(i) The diamond content of the samples as determined by caustic
 dissolution may not be representative of the overall diamond content
 of the CH-6 kimberlite due to a number of factors including the limited
 area of the kimberlite from which the drill core samples were collected
 and the relatively small size of the samples.
(ii) Results for samples of drill core first reported on September 21,2009

Mr. Brooke Clements, President of Peregrine stated "The results we have received from the cumulative 0.569 tonne sample collected from CH-6 are truly outstanding. The presence of ten diamonds larger than 0.10 carats in size from such a small sample suggests that we should see a good population of large, commercial-size diamonds when larger samples are collected from CH-6. It is still very early in the exploration cycle at Chidliak and already 16 kimberlites have been discovered. All twelve of the kimberlites tested so far are diamondiferous and four of these, CH-1, CH-2, CH-6 and CH-7 have produced commercial-size, +0.85 mm diamonds from small kimberlite samples. In addition, CH-10 and CH-12 show promising coarse diamond size distributions and additional drilling and sampling of these kimberlites is warranted. We have only drilled for eight weeks with one drill, drilling 4,000 metres and testing only 15 targets. Less than 15 percent of the property has been flown with airborne geophysics and a comprehensive property-wide heavy mineral sampling programme was completed just this summer. Over 200 anomalies from the existing airborne survey require follow-up and a significantly expanded airborne survey is being planned for early 2010. We are confident that we will discover additional kimberlites with economic potential next year."

CHARACTERISTICS OF THE CH-6, CH-10 AND CH-12 KIMBERLITES AND LARGE CH-6 DIAMONDS

The discovery of the CH-6 kimberlite was reported by Peregrine on August 6, 2009, with additional drilling information reported on September 14, 2009. The CH-6C sample consisted of magmatic kimberlite collected from drill hole number five in the southeastern portion of the pipe. The sample material is described as massive kimberlite with 40 to 50 percent olivine macrocrysts up to ten millimetres in size, abundant garnet and chrome diopside grains and abundant mantle xenoliths up to eight centimetres in size. The following table presents descriptions provided by the SRC for the nine diamonds larger than the 1.700 mm sieve size recovered from the 170.3 kg CH-6C sample.

Twenty-three of the 47 diamonds larger than the 0.85 mm sieve size from the CH-6C sample were classified by the SRC as having a white (colourless) colour, twenty-one were described as off-white and three were yellow. Photos of a selection of diamonds and drill core from CH-6, together with maps showing CH-6, CH-10 and CH-12 are available on Peregrine's web-site at [ http://www.pdiam.com/i/pdf/chidliak289.pdf ].

The discovery of CH-10 was first reported on September 14, 2009. The kimberlite was discovered by drilling two inclined holes across a magnetic low anomaly with an approximate surface diameter of 50 metres. CH-10 is one of four magnetic low anomalies aligned in a north-northwest direction along a 600 metre trend, referred to as the "string of pearls", just north-northwest of the CH-6 kimberlite. The material in the 111.4 kg CH-10 sample was described as massive phlogopite-bearing magmatic kimberlite with 30 to 50 percent olivine macrocrysts up to ten millimetres in size, abundant mantle-derived garnets and minor ilmenite and chrome diopside.

As reported on September 14, 2009, CH-12 was discovered when an area of kimberlite outcrop and subcrop was identified while prospecting a magnetic high geophysical anomaly measuring approximately 100 metres by 50 metres. The material in the 251.7 kg CH-12 sample was described as massive pyroclastic kimberlite with less than five percent country rock xenoliths including limestone, 40 to 50 percent olivine macrocrysts up to ten millimetres in size and abundant indicator minerals.

Twelve of the 16 kiimberlites discovered to date at Chidliak have been tested for diamonds and all of these are diamondiferous. Diamond results for the last four kimberlites discovered in 2009, CH-13 through CH-16, are expected later this quarter. Relevant information regarding the 50 tonne mini-bulk sample of CH-1 and the 2010 Chidliak exploration programme will be released when it becomes available.

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.

Mr. Peter Holmes, P. Geo., Peregrine's Vice President, Exploration, is a Qualified Person under NI 43-101 and is responsible for the design and conduct of the programs carried out by the Company on the Chidliak property. Mr. Holmes has reviewed this release and approves of its contents.
