Peregrine Provides Update on 2015 Diamond Resource Development Program

March 23, 2015 PDF version

Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) (TSX:PGD) is pleased to provide an update on its 100 percent-owned Chidliak diamond project (“Chidliak” or the “Project”). Chidliak is located 120 kilometres northeast of Iqaluit, the capital of Nunavut, Canada. The planned objective of Peregrine’s 2015 Diamond Resource Development program is to confirm the grade estimates and provide representative diamond parcels to enable valuation of diamonds recovered from the CH-6, CH-7 and CH-44 kimberlite pipes. Kimberlites bulk sampled in the 2015 program will be included in a planned 2016 Preliminary Economic Assessment on a potential Phase 1 diamond mine development at Chidliak.

2015 DIAMOND RESOURCE DEVELOPMENT PROGRAM

The 2015 bulk sample program plans for the collection of bulk samples from the CH-6, CH-7 and CH-44 kimberlites by large diameter RC drilling (up to 26 inch/66 cm diameter). The work is designedto confirm continuity of diamond grade throughout the kimberlite bodies and obtain parcels of diamonds for valuation. If results warrant, Peregrine would prepare maiden resource statements for CH-7 and CH-44 and update the CH-6 resource.

Mobilisation of the bulk sample equipment into the Chidliak site from Iqaluit was completed on March 8, 2015 using an overland trail and Hercules transport aircraft. Drilling has commenced on the first of six holes planned for the CH-7 kimberlite. This first hole has a planned total depth of 220 metres and is the first of three holes planned to provide grade confirmation and representative diamonds for the KIM-2 unit of the CH-7 kimberlite.

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. The 2015 bulk sampling program focused on priority kimberlites has commenced. The objective of the 2015 program is to delineate a resource base that would be the subject of a Preliminary Economic Assessment in 2016.
