Peregrine Announces High Diamond Counts for CH-52 and CH-58 Kimberlites at Chidliak

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/06/11 -- Peregrine Diamonds Ltd. ('Peregrine' or 'the Company') (TSX: PGD) is pleased to report microdiamond results from the CH-52 and CH-58 kimberlites which were discovered earlier this year on the 8,580 square kilometre Chidliak project ('Chidliak' or 'the Project'), Baffin Island, Nunavut, Canada. A 208.4 kilogram sample collected by core drilling from the CH-52 kimberlite yielded 252 diamonds larger than the 0.106 mm sieve size, including four diamonds larger than the 0.850 mm sieve size which weigh a total of 0.045 carats. In addition, a 194.9 kilogram sample from the CH-58 kimberlite yielded 428 diamonds larger than the 0.106 mm sieve size, including one diamond larger than the 0.850 mm sieve size. Diamond results for eight more kimberlites from Chidliak are expected during the fourth quarter of 2011 and the first quarter of 2012.

As announced on June 2, 2011, the CH-52 kimberlite was discovered with the drilling of one vertical reverse circulation hole. Due to the presence of abundant kimberlite indicator minerals in the drill cuttings, two angle core holes were subsequently drilled across the body. The 208.4 kilogram sample reported here was collected from the drill core. The kimberlite is located approximately 200 metres south of the Sunrise camp and is five kilometres to the east of the Southern Focus Area, an area with an eight kilometre radius that hosts six of the seven kimberlites identified to date at Chidliak with economic diamond mining potential. The surface area of CH-52 is estimated at 0.2 hectares.

As announced on June 22, 2011, the CH-58 kimberlite was discovered by drilling two angled core holes across the body. CH-58 is located approximately 20 kilometres north of the CH-6 kimberlite and 300 metres south of the CH-55 kimberlite. As announced on September 12, 2011, a 195.6 kilogram sample from CH-55 yielded 214 diamonds larger than the 0.106 mm sieve size including one diamond larger than the 1.18 mm sieve size that weighed 0.03 carats. Both CH-55 and CH-58 are estimated to be over 0.5 hectares in size based on geophysical and drill data.

The following table summarizes caustic fusion diamond results from the CH-52 and CH-58 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories ('the SRC').

Three of the four diamonds larger than 0.850 mm in the CH-52 sample were characterized by the SRC as being white/colourless and one was off-white. The diamond larger than 0.850 mm in the CH-58 sample was also described as being white/colourless.

With the presence of commercial-size diamonds in small samples collected from CH-52, CH-55 and CH-58, more work will be scheduled on these kimberlites to determine their economic potential. Images of the CH-52, CH-55 and CH-58 kimberlites are available on Peregrine's website at www.pdiam.com/i/pdf/Chidliak416.pdf.

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.

Chidliak is a joint venture between Peregrine (49%) and BHP Billiton (51%).
