Peregrine Identifies New Zone With High Diamond Counts at Chidliak CH-7 Kimberlite Pipe

VANCOUVER, BRITISH COLUMBIA--(Marketwired - March 10, 2015) - Peregrine Diamonds Ltd. ("Peregrine " or "the Company") (TSX:PGD) is pleased to report the final caustic fusion diamond results from the 2014 Diamond Resource Development Program at Peregrine's 100% owned Chidliak diamond project ("Chidliak") in Nunavut, Canada. Caustic fusion analyses were performed on representative drill core from the CH-6, CH-7, CH-44 and CH-46 kimberlite pipes by the Saskatchewan Research Council Geoanalytical Laboratories. These four pipes lie within the Southern Priority Area, an area approximately eight kilometres in diameter that contains seven of the eight kimberlite pipes that Peregrine has been focused on since 2012.

Results have identified a new geologic domain within CH-7 that contains some of the highest total diamond counts defined to date at Chidliak. In addition, new results from CH-6 have further confirmed that the previously known coarse diamond distribution extends to depth in the expanded Inferred Mineral Resource. Finally, the latest results from CH-44 have extended the known coarse diamond distribution to 210 metres vertical depth.

Mr. Tom Peregoodoff, Peregrine's President and CEO said, "The new results from our 2014 Diamond Resource Development Program show that there is tremendous potential to add significant carats to Chidliak. Our work in 2014 added over one million carats to our Inferred Resource at CH-6, an increase of 15%. The new results from CH-7 define a previously unknown geological domain that has the potential to exceed the resource grade of 2.58 carats per tonne ("cpt") established at CH-6. The 2015 Diamond Resource Development Program has now commenced and is designed to confirm the grade estimates and provide diamond parcels to enable valuations for the key kimberlite pipes that will be included in a planned 2016 Preliminary Economic Assessment on a potential Phase 1 diamond mine development at Chidliak."

CH-6 DIAMOND RESULTS

The 2014 Diamond Resource Development Program drilling at CH-6 was comprised of 1183 metres in five core holes focused on expanding the CH-6 Inferred Resource. Caustic fusion results from samples of CH-6 are stated in Table 1.

a 2014 caustic fusion result
b CH-6 KIM-L result from 2013 trench bulk sample site, per company press release dated December 3, 2013

KIM-L is the dominant geological domain within CH-6 and was sampled during the 2013 bulk sample program reported on January 16, 2014. The current CH-6 Inferred Resource of 8.57 million carats is composed entirely of KIM-L.

The results reported here are consistent with previously reported caustic fusion data from CH-6 and provide further confirmation that the high diamond grades established by surface trenching in 2013 and by Dense Media Separation testing of drill cores in 2010 continue throughout the pipe and to depth (see December 3, 2013 and December 6, 2010 company press releases and NI 43-101 technical report effective January 26, 2015).

CH-7 DIAMOND RESULTS

The 2014 Diamond Resource Development Program drilling at CH-7 was comprised of 1128 metres in seven core holes. Caustic fusion sample results are shown in Table 2. The 2014 and prior drilling data now underpin a new CH-7 kimberlite pipe model with five geological domains, labelled KIM-1 through KIM-5.

a 2014 caustic fusion result
b Reported in company press release dated February 22, 2011

As reported on November 22, 2010, a 47.2 dry tonne mini-bulk sample from KIM-1 at CH-7 returned a grade of 1.04 cpt for +0.85 mm diamonds, including a 6.53 carat diamond. The 2014 caustic fusion results illustrate that the KIM-5 geological domain contains diamonds in quantities substantively exceeding the 1.04 cpt grade benchmark of KIM-1, while the KIM-3 and KIM-4 domains have diamond contents similar to the benchmark. Large diameter drilling for the 2015 Diamond Resource Development Program is focused on verifying the commercial diamond grade of the KIM-2, KIM-3, KIM-4 and KIM-5 geological domains in CH-7 and obtaining representative parcels of diamonds for independent valuation.

CH-44 DIAMOND RESULT

The 2014 Diamond Resource Development Program drilling at CH-44 was comprised of 994 metres in six core holes. The caustic fusion result for a sample of the dominant geological domain at CH-44 collected from a depth interval of 154-210 metres is listed in Table 3. The result is consistent with previously reported caustic fusion data for 535 kg of material taken from the same major geological domain at a shallower depth (5-104 metres). It is also similar to caustic fusion data corresponding to the 1.04 cpt grade benchmark for domain KIM-1 at CH-7.

a 2014 caustic fusion result
b Reported in company press release dated November 21, 2011

The 2014 caustic fusion results have extended the known coarse diamond distribution to 210 metres vertically below the surface. Previously the known depth extent of the coarse diamond distribution was 162 metres vertically below the surface. The deepest kimberlite intersection from CH-44 is 222 metres vertically below the surface and the kimberlite pipe remains open at depth.

CH-46 DIAMOND RESULTS

As reported on December 8, 2014, the CH-46 kimberlite was tested in three core holes that intersected 134 cumulative metres of limestone-bearing volcaniclastic kimberlite. The caustic fusion results reported in Table 4 consumed most of the kimberlite core from two of the three holes drilled. These results confirm the economic potential of CH-46.

ABOUT PEREGRINE DIAMONDS

Peregrine Diamonds 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, 582,477 hectare Chidliak project, located 120 kilometres from Iqaluit, the capital of Nunavut, 71 kimberlites have been discovered to date with eight being potentially economic. An Inferred Mineral Resource of 8.57 million carats in 3.32 million tonnes of kimberlite at a grade of 2.58 carats per tonne has been defined for a portion of the CH-6 kimberlite. In April 2013, a bulk sample weighing 404.2 dry tonnes was collected from CH-6. This sample returned a grade of 2.58 carats per tonne for diamonds larger than the 1.18 mm sieve size. An independent diamond valuation of the resulting 1,013 carat parcel of diamonds returned an average market price of US$213 per carat and modelled prices that ranged from a minimum of US$162 per carat to a high of US$236 per carat, with a base model price of US$188 per carat. As part of the ongoing resource development program, core and small diameter RC drilling was completed at the CH-6, CH-7 and CH-44 kimberlites in 2014. Preparations are well underway for a 2015 bulk sampling program focussed on priority kimberlites that is scheduled to commence in March 2015. The objective of the 2015 program is to delineate a resource base that would be the subject of a Preliminary Economic Assessment in 2016.

At the 8,493 hectare Lac de Gras project in the Northwest Territories, located approximately 23 kilometres from the Diavik Diamond Mine,the nine hectare 72.1%-owned DO-27 kimberlite hosts an Indicated 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 and it is open at depth. Peregrine Diamonds also continues to evaluate earlier stage exploration projects it controls in Nunavut and the Northwest Territories.

Through comprehensive evaluation of its extensive and proprietary diamond exploration databases, the Company, through its wholly owned subsidiary Peregrine Exploration Ltd, is working towards acquiring and developing new diamond properties in Canada. A key asset being utilized in the 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 approximately three million square kilometres of Canada.

For information on data verification, exploration information and resource estimation procedures see the technical reports entitled, "2015 Technical Report for the Chidliak Project, 66° 21' 43" W, 64° 28' 26" N Baffin Region, Nunavut" dated February 23, 2015, and "Peregrine Diamonds Ltd.
