Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) is very pleased to report the discovery of large diamonds and a coarse diamond size distribution in representative drill core samples collected from the CH-6 kimberlite located on the 9,800 square kilometre Chidliak project (“Chidliak”), Baffin Island, Nunavut, Canada. A 398.8 kilogram sample collected from CH-6 yielded 2,730 diamonds larger than the 0.075 mm sieve size, including 131 diamonds larger than the 0.600 mm sieve size. The largest diamond recovered from the sample was a 0.62 carat white, transparent aggregate. The CH-5 kimberlite was also determined to be diamondiferous with a 423.7 kilogram surface sample yielding 49 diamonds larger than the 0.075 mm sieve size.The following table summarizes caustic fusion diamond results for the CH-6 and CH-5 kimberlites. The analyses were performed at the Saskatchewan Research Council Geoanalytical Laboratories (“the SRC”).
Mr. Eric Friedland, CEO of Peregrine stated “We believe these microdiamond counts from CH-6 are some of the best results in the history of Canadian diamond exploration and a testament to the outstanding potential of Chidliak.”
Mr. Brooke Clements, Peregrine’s President stated “The microdiamond results from CH-6 are some of the strongest I have seen in my 27 year career in diamond exploration and to my knowledge, are the best publicly disclosed microdiamond results from a Canadian kimberlite since the discovery of the A-154 pipe at Diavik in the Northwest Territories in 1994. Having just completed our first drill programme at Chidliak, we are at the start of the exploration cycle and we expect to discover more kimberlites with the economic potential of CH-1 and CH-6. Over the next few months we will be receiving diamond results from 11 additional kimberlites discovered this year, and from the 50 tonne sample collected from CH-1. We are confident that more diamondiferous kimberlites will be discovered during the 2010 field programme.”
CH-6 DIAMONDS AND CHARACTERISTICS OF THE CH-6, CH-10 AND CH-5 KIMBERLITES
The following table presents descriptions provided by the SRC for the nine diamonds larger than the 1.700 mm sieve size.
Thirty of the 62 diamonds larger than the 0.85 mm sieve size from CH-6 were classified as having a white colour, eighteen were described as off-white, ten were yellow and four were grey or brown. Photos of a selection of diamonds and drill core from CH-6 are available on Peregrine’s web-site at http://www.pdiam.com/i/pdf/chidliak983.pdf.
The discovery of the CH-6 kimberlite was reported by Peregrine on August 6, 2009, with additional drilling information reported on September 14, 2009. The CH-6A sample was collected in a representative manner from vertical drill hole number two between the depths of 75 and 246 metres. The sample is described as consisting of uniform primary volcaniclastic kimberlite with five to 15 percent country rock xenoliths including carbonate rocks, abundant mantle xenoliths and 40 to 50 percent olivine macrocrysts up to nine millimetres in size. The CH-6B sample was collected from inclined drill holes one and three and is described as being texturally variable volcaniclastic kimberlite with layering and varying concentrations of mantle xenoliths and olivine macrocrysts. Magmatic kimberlite is also present at CH-6 and a 200 kilogram sample collected from drill hole number five has been submitted for caustic fusion analysis. Volcaniclastic kimberlite can contain fragments of kimberlitic material and other rock types and forms as a result of near-surface explosive volcanic activity. Magmatic kimberlite represents the original kimberlite magma that has not been exposed to explosive volcanic activity.
The discovery of the CH-10 kimberlite was reported on September 14, 2009. This kimberlite was discovered by drilling one of four magnetic low anomalies aligned for approximately 600 metres like a “String of Pearls” in a north-northwest direction from the CH-6 kimberlite pipe. The CH-10 kimberlite is described as magmatic with 40 to 50 percent olivine macrocrysts up to ten millimetres in size, and abundant mantle-derived garnets. In light of the results from CH-6, a sample of approximately 100 kilograms of CH-10 is being submitted for microdiamond analysis.
Further work including detailed ground geophysics and drilling to investigate the overall kimberlite tonnage potential of the CH-6 pipe and the associated “String of Pearls” system is planned for the 2010 exploration programme.
The discovery of the CH-5 kimberlite at surface was reported by the Company on July 16, 2009. The CH-5A sample was collected from surface volcaniclastic kimberlite material that is described as having less than five percent country rock xenoliths including limestone and minor amounts of olivine macrocrysts and other indicator minerals. The CH-5B surface sample is described as fine-grained magmatic kimberlite with no visible country rock xenoliths and minor olivine macrocrysts.
The SRC is an independent laboratory that is accredited by the Standards Council of Canada to the ISO/IEC Guide 25 standard for diamond recovery by caustic fusion. The kimberlite samples were collected, sealed in secure containers and shipped to the SRC under strict chain of custody protocols supervised by senior Peregrine personnel.
Peregrine is the operator of the 2009 Chidliak exploration programme which is being fully funded by BHP Billiton. As announced on November 24, 2008, BHP Billiton has elected to exercise its earn-in rights for Chidliak and, under the terms of the earn-in agreement, must incur a total of $22.3 million dollars in exploration expenditures in order to earn a 51% interest in Chidliak.
Mr. Peter Holmes, P. Geo., Peregrine’s Vice President, Exploration, is a Qualified Person under NI 43-101 and is responsible for the design and conduct of the programs carried out by the Company on the Chidliak property. Mr. Holmes has reviewed this release and approves of its contents.
