Peregrine Provides Chidliak Update and Announces Discovery of Three New Kimberlites

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 9, 2013) - Peregrine Diamonds Ltd. ("Peregrine" or "the Company") (TSX:PGD) is pleased to provide an update on activities at its 100 percent-owned Chidliak project ("Chidliak" or "the Project"), located on Baffin Island, 120 kilometres from Iqaluit, the capital of Nunavut, Canada. The Chidliak summer exploration program operated by De Beers Canada Inc. ("De Beers") was completed on August 19. Highlights from this program include the discovery by De Beers of two new kimberlites and the discovery of a kimberlite dyke by government geologists. In addition, possible kimberlite float, which is undergoing final petrographic confirmation by De Beers, was found in numerous other locations. As reported on April 23 and June 5, 2013, Peregrine collected a bulk sample weighing approximately 508 wet tonnes from the CH-6 kimberlite by surface trenching. Approximately 470 wet tonnes of this sample has been transported from Iqaluit to the De Beers dense media separation ("DMS") facility in Sudbury, Ontario. Approximately ten wet tonnes of kimberlite was processed at the Saskatchewan Research Council ("the SRC") in July and the approximately 28 wet tonnes of kimberlite material that remains in Iqaluit will be shipped to Sudbury this month. Processing of approximately 250 wet tonnes of the bulk sample by DMS is scheduled to commence in late September at the De Beers DMS facility. This processing will be performed by De Beers and is expected to yield a heavy mineral concentrate weighing approximately 1.8 dry tonnes. Final diamond recovery from this concentrate will be managed by Peregrine and will be undertaken at the SRC. The final diamond recovery process will be initiated upon De Beers delivering to the Company notice of their decision regarding their right to enter into an earn-in and joint venture agreement for Chidliak.

The De Beers summer exploration program at Chidliak included the evaluation of priority geophysical anomalies by prospecting, orientation geophysical surveys, and bedrock and surficial mapping. During the course of the program, De Beers field teams discovered two new kimberlite occurrences and numerous occurrences of possible kimberlite float requiring additional work before being confirmed. The first confirmed discovery is a kimberlite dyke approximately one metre wide associated with a circular magnetic anomaly with an estimated surface expression from ground magnetics of approximately 0.5 hectares. At the second site, kimberlite float was found associated with a circular geophysical anomaly that has an estimated surface expression from airborne magnetics of approximately 0.5 hectares. Concurrent with the De Beers Chidliak exploration program, the Canada Nunavut Geoscience Office ("CNGO") conducted a bedrock and surficial mapping program over a portion of the Hall Peninsula of Baffin Island. During the course of their fieldwork, the CNGO reported the discovery of a new kimberlite dyke on the Project. In total three new confirmed kimberlites have been discovered in 2013 bringing the total number of kimberlites at Chidliak to 64.

De Beers completed ground geophysical orientation surveys over twelve known kimberlites using the following methods: gravity, electromagnetics, ground penetrating radar and magnetics. The results from these surveys will be used to determine the most effective geophysical technique for discovering additional kimberlites in future exploration programs. To date initial results from the gravity surveys have been reviewed by Peregrine and indicate that most of the known kimberlites that were surveyed have a strong gravity response. Prior to this year, no gravity surveys had been executed on the Project. Peregrine believes that gravity could play a key role in future kimberlite discoveries at Chidliak. A complete summary of the summer exploration program, including confirmation of additional kimberlite discoveries, and results from the other geophysical surveys will be provided after all information from the program has been evaluated by Peregrine.

Approximately 470 wet tonnes of CH-6 bulk sample material is now stored at the De Beers DMS facility in Sudbury, Ontario. De Beers will commence processing approximately 250 wet tonnes of this material in late September, monitored by a Qualified Person designated by Peregrine. Final diamond recovery at the SRC, which will also be monitored by a Qualified Person designated by Peregrine, will commence after De Beers provides Peregrine notice of their decision regarding their right to enter into an earn-in and joint venture agreement for Chidliak. Final results, including independent diamond valuations, are expected early in the second quarter of 2014. Peregrine's objective is to utilize these results, together with geologic and diamond content information acquired from core drill programs in 2009, 2010 and 2011, to develop a preliminary revenue model and establish an intial resource for CH-6. The remainder of the bulk sample will be processed at a later date. The DMS processing and diamond recovery costs for the 250 tonne sample will be credited to De Beers' earn-in should they exercise their option to enter into a joint venture with Peregrine for Chidliak. In the event De Beers elects not to exercise their option, Peregrine is not required to reimburse them for these costs.

In order to optimize the flow sheet for DMS processing of the CH-6 bulk sample, ten wet tonnes of kimberlite material were processed by DMS at the SRC in July. Howard Coopersmith, Peregrine's external Qualified Person for sample processing and diamond recovery stated, "The CH-6 sample material processed very well and we expect no processing problems and optimum diamond liberation". The concentrate that resulted from the processing of this sample is securely stored at the SRC and will be combined with the concentrate that will be produced at the De Beers DMS facility in Sudbury from the initial 250 tonne sample. All the concentrate will undergo final diamond recovery at the SRC which will be monitored by Peregrine.

Mr. Alan O'Connor, Professional Geologist, Peregrine's Chidliak Project Manager, is a Qualified Person under National Instrument 43-101 and is responsible for the design and conduct of the programs carried out by the Company at Chidliak, including the collection of the CH-6 bulk sample. Mr. Howard Coopersmith, an independent consultant to the diamond industry, is Peregrine's external Qualified Person for sample processing and diamond recovery.

Messrs. O'Connor and Coopersmith have reviewed this release and approve of its contents.

ABOUT PEREGRINE DIAMONDS

Peregrine is a diamond exploration and development company focused on Canada's North. The Company has discovered two new diamond districts in Nunavut, Nanuq in 2007 and Chidliak in 2008. At its 100 percent-owned Chidliak project, located 120 kilometres from Iqaluit, the capital of Nunavut, 64 kimberlites have been discovered to date, and Peregrine collected a bulk sample weighing 508 wet tonnes from the CH-6 kimberlite in 2013. A 14.11 tonne sample of drill core acquired from CH-6 in 2010 returned a grade of 2.84 carats per tonne. The Project is subject to an option agreement with De Beers whereby De Beers has the exclusive right until December 31, 2013 to enter into an earn-in and joint venture agreement for Chidliak on a 50.1 percent De Beers / 49.9 percent Peregrine, basis. At its 72 percent-owned, nine hectare DO-27 kimberlite in the Northwest Territories, located 27 kilometres from the Diavik Diamond Mine, a NI 43-101 compliant mineral resource of 18.2 million carats of diamonds in 19.5 million tonnes of kimberlite at a grade of 0.94 carats per tonne, which is open at depth, was confirmed in 2008. Peregrine also continues to evaluate earlier stage diamond exploration projects it controls in Nunavut and the Northwest Territories and through comprehensive evaluation of its extensive and proprietary diamond exploration databases, is working towards discovering new diamond districts in North America. A key asset being utilized in Peregrine's search for a new Canadian diamond district is a proprietary database acquired from BHP Billiton that contains data from approximately 38,000 kimberlite indicator mineral samples covering an area of Canada of approximately three million square kilometres.
