NI-43-101 Technical Report Filed For The Chidliak Project
Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) (TSX:PGD) is pleased to provide an activity update on its 100 percent-owned Chidliak project (“Chidliak”), located 120 kilometres from Iqaluit, the capital of Nunavut, Canada. In March and April, 2,250 line kilometres of ground geophysics was completed over priority areas. In addition, 24 overburden profile holes were drilled with a small diameter reverse circulation (“RC”) rig on the CH-7 and CH-44 kimberlites, confirming shallow overburden depths of less than three metres over these pipes. Logistical and technical preparations continue for the planned 2015 bulk sampling program where at least three kimberlites will be evaluated by large diameter RC drilling. New diamond results from the CH-46 kimberlite, which was discovered by RC drilling in 2010, are consistent with economic potential. New diamond results from samples of drill core collected from the CH-1, CH-7 and CH-44 kimberlites in 2012 further support the determination that these kimberlites have economic potential.
WINTER 2014 FIELD PROGRAM AND BULK SAMPLE PREPARATION
In March and April, a total of 2,250 line kilometres of high resolution ground magnetic surveying was completed over an area that includes the Southern Priority Area. The Southern Priority Area hosts seven kimberlites with economic potential including CH-6, CH-7 and CH-44 that are scheduled for bulk sampling in 2015, and CH-46. The surveys were completed to refine the interpretation of kimberlite indicator mineral anomalies and to generate additional priority kimberlite targets.
During April, fifteen overburden profile holes were drilled at CH-44 and nine were drilled at CH-7 to assist with the preparation of geologic models and prepare for future bulk sampling programs. Average overburden depths over the kimberlites are 2.5 and 2.7 metres respectively. This confirms that CH-44 and CH-7 are amenable to the collection of bulk samples by trenching to obtain parcels of diamonds suitable for valuation.
Preparations underway for a 2015 bulk sampling program by large diameter RC drilling include the following:
INITIAL CH-46 DIAMOND RESULTS
The CH-46 kimberlite was discovered in 2010 by RC drilling of a magnetic anomaly with an estimated surface expression of 0.9 hectares as determined by ground magnetics. CH-46 is located 1.4 km south-southeast of CH-7 and 1.5 km north-northwest of CH-44. Peregrine has recently undertaken a review of all known kimberlites within the Southern Priority Area. This work highlighted the potential economic signifigance of CH-46. An 80 kilogram sample of RC chips from CH-46 has been analyzed and it yielded 246 diamonds larger than the 0.106 mm sieve size, including two diamonds larger than the 0.600 mm sieve size. These diamond results are encouraging and suggest that CH-46 has economic potential. The CH-46 kimberlite will be the subject of a future core drilling program to better assess diamond content and constrain the size and geology of the pipe.
CH-1, CH-7 and CH-44 DIAMOND RESULTS
In 2012, three core holes totalling 637 metres were drilled into the CH-1 kimberlite to better constrain its size and geology. A cumulative 351.68 kilogram sample of drill core collected from the three holes returned 411 diamonds larger than the 0.106 mm sieve size, including nine diamonds larger than the 0.85 mm sieve size. CH-1 was discovered by prospecting in 2008. That year, a combined 2.28 tonne sample collected from outcrop and surface float returned a grade of 1.56 carats per tonne. A 2.01 carat gem quality, clear colourless octrahedron was recovered from the 2.28 tonne sample. A 49.6 tonne surface sample from the small outcrop at CH-1 returned a grade of 0.41 carats per tonne. The estimated surface expression of CH-1 is approximately one hectare.
In 2012, four core holes totalling 983 metres were drilled into the CH-7 kimberlite to better constrain the geology and diamond content and to establish pilot holes for future bulk sampling. A cumulative sample of drill core weighing 568.02 kilograms returned 715 diamonds larger than the 0.106 mm sieve size, including 19 diamonds larger than the 0.85 mm sieve size. The largest diamond was a 0.28 carat off-white transluscent aggregate with no inclusions. CH-7 has an estimated surface expression of one hectare. On May 07, 2014 Peregrine reported a kimberlite tonnage estimate for CH-7 of between 2.75 million and 3.97 million tonnes from surface to a depth of 280 metres. A 47 tonne mini-bulk sample collected from the surface of CH-7 returned a grade of 1.04 carats per tonne and yielded diamonds weighing 6.53 and 2.18 carats.
In 2012, four core holes totalling 758 metres were drilled into the CH-44 kimberlite to better constrain the geology and diamond content and to set pilot holes for future bulk sampling. A cumulative 765.48 kilogram sample of the drill core returned 1,470 diamonds larger than the 0.106 mm sieve size, including 22 diamonds larger than the 0.85 mm sieve size. The largest diamond was a 0.09 carat off-white transparent fragment with no inclusions. CH-44 has a surface expression of approximately 0.5 hectare. On May 07, 2014, Peregrine reported a kimberlite tonnage estimate of between 1.16 and 2.05 million tonnes from surface to a depth of 230 metres. Encouraging caustic fusion diamond results from a 535 kilogram sample of drill core suggest economic potential.
The following table summarizes previously unreported caustic fusion diamond results from the CH-46, CH-1, CH-7 and CH-44 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories.

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, 67 kimberlites have been discovered to date with nine being potentially economic. In April 2013, Peregrine collected a bulk sample weighing 404 dry tonnes from the CH-6 kimberlite. The 404 tonne 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. The 2014 exploration program has commenced and planning is now underway for an important 2015 resource definition program that will be designed to advance Chidliak to the feasibility stage.
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 additional 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 approximately three million square kilometres of Canada.
