Peregrine Provides Chidliak Update

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 9, 2015) - 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. Peregrine has successfully completed the 2015 field work program which was focused on continued development and expansion of the Chidliak diamond resource. Transportation of the 2015 CH-7 bulk sample from Iqaluit to Saskatoon is now complete. Dense Media Separation ("DMS") processing of the 558.5 wet tonne sample at the Saskatchewan Research Council ("SRC") will commence on September 14, 2015. The 2015 summer program was completed successfully approximately three weeks ahead of schedule. A total of 1,361 metres of core drilling was completed; 520 metres at CH-6 and 841 metres at CH-7. In addition, a total of 3,345 kilograms of kimberlite from CH-6 and CH-7 has been sampled and sent to the SRC for microdiamond analysis. Ongoing environmental base line studies were also completed.

The objective of the 2015 Chidliak Diamond Resource Development program is to define a resource base that would be the subject of a 2016 Preliminary Economic Assessment on a Phase 1 diamond mine. The 2015 program consists of a bulk sample of CH-7 (the 2015 Bulk Sample Program) and summer core drilling and microdiamond sampling (the Summer 2015 Program).


The 2015 bulk sample program consisted of six large-diameter drill holes drilled to a maximum depth of 240 metres at CH-7. Transportation of the 558.5 wet tonnes of screened CH-7 kimberlite to secure storage facilities at the SRC has been completed. The sample is currently being separated into processing batches and the DMS plant is going through cleaning and final preparation. The SRC advises that processing of KIM-5 bulk sample material will commence on September 14, 2015. The 2015 CH-7 bulk sample results will provide diamond grades for kimberlite units KIM-2, KIM-3, KIM-4 and KIM-5, as well as representative diamond parcels for independent valuation.

The Company expects processing of the CH-7 bulk sample to a concentrate to be complete on or before November 30, 2015, two weeks later than earlier guidance, due to adverse sea ice conditions which delayed transportation of the bulk sample from Iqaluit to Saskatoon by approximately one month. Final diamond recovery is expected by early January 2016 with initial diamond grade results being released shortly thereafter. Independent diamond valuation results are expected in the first quarter of 2016.


The summer program is complete and was focused on proving up previously identified resource expansion opportunities at CH-6 and CH-7 ahead of the planned 2016 Preliminary Economic Assessment. The summer 2015 work program accomplished four key elements:

  • Sampling of Existing CH-6 Core. Microdiamond and ancillary data sets for the southern, northern and at-depth portions of CH-6 were expanded. Approximately 715 kilograms of representative microdiamond samples were collected from six previously drilled core holes.
  • CH-6 Core Drilling. Two near-vertical core holes were drilled to 260 metres depth each to extend known geological and grade continuity into the southern portion of CH-6 that currently is categorized as Target for Further Exploration ("TFFE"). Both of these holes ended in kimberlite. Approximately 367 kilograms of microdiamond samples were collected along the length of both holes.
  • Sampling of Existing CH-7 Core. Microdiamond and ancillary data sets for the KIM-2, KIM-3 and KIM-4 domains at CH-7 were expanded. Approximately 1,200 kilograms of representative microdiamond samples were collected from eleven previously drilled core holes.
  • CH-7 Core Drilling. Three near-vertical core holes totalling 663 metres were drilled in the southern portion of CH-7 to prove up geological and grade continuity, primarily within unit KIM-2. All three holes ended in kimberlite. A fourth vertical hole was drilled to a depth of 177.5 metres in the northern portion of CH-7 to further constrain KIM-5 and KIM-4 geology and provide control on the at-depth shape of the CH-7 pipe. This fourth hole intersected the kimberlite/country rock contact at 170.5 metres. Approximately 1,062 kilograms of representative microdiamond samples were collected along the length of all four holes.

A total of 3,345 kilograms of core sample acquired during the 2015 summer and previous core drill programs has been dispatched to the SRC for microdiamond recovery using caustic fusion. Results are expected through October and November 2015. Successful integration of the 2015 bulk sample results with microdiamond and ancillary geological data will enable the Company to maximize the Inferred Resource estimates for both CH-6 and CH-7. The revised Inferred Resource base for CH-6 and CH-7 is expected to be released in the first quarter of 2016. This resource base will form the foundation of a planned Preliminary Economic Assessment on a potential Phase 1 diamond mine development at Chidliak, expected in the second quarter of 2016.

At the Chidliak project 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 addition, a TFFE of 3.20 to 4.38 million tonnes of kimberlite to a depth of 380 metres below surface has been identified at CH-6. An independent diamond valuation of a 1,013 carat parcel of diamonds from CH-6 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. A TFFE of 3.72 to 6.01 million tonnes to a depth of 290 metres has been defined at the CH-7 kimberlite. In 2010, a 47 tonne mini-bulk sample collected from the surface of CH-7 returned a grade of 1.04 carats per tonne. A TFFE of 1.27 to 3.19 million tonnes to 250 metres depth has been defined at the CH-44 kimberlite pipe. The Tonnages for Further Exploration identified above are conceptual in nature and are not Mineral Resources. It is uncertain whether further exploration will result in any of these Tonnages being delineated as Mineral Resources.

Peregrine Diamonds core asset is its 100 percent-owned, 582,476 hectare Chidliak project, located 120 kilometres from Iqaluit, the capital of Nunavut.

In addition, Peregrine now controls eight prospective diamond prospecting licenses in Botswana that cover 5,746 km2. Further target generation and the drill testing of four priority targets are planned for the Botswana project in 2015.

Peregrine Exploration, a wholly owned subsidiary of Peregrine Diamonds holds the 8,493 hectare Lac de Gras project in the Northwest Territories, located approximately 27 kilometres from the Diavik Diamond Mine. The nine hectare 72.1%-owned DO-27 kimberlite, located at Lac de Gras, 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. Through comprehensive evaluation of its extensive diamond exploration databases, Peregrine Exploration, is working towards acquiring and developing new diamond properties in North America. 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.
