Peregrine Discovers Two Kimberlites At Lac De Gras, Canada

April 16, 2012 PDF version
Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) (TSX:PGD) is pleased to report that it has discovered two kimberlites in the Lac de Gras region, Northwest Territories, Canada. The kimberlites, named LD-1 and LD-2, were discovered when the first two land-based geophysical targets scheduled for core drilling were drilled earlier this month. Lac de Gras, home to the EKATI and Diavik diamond mines, is one of the most prolific diamond districts in the world since kimberlite was first discovered there in 1991.

The core drill is now being moved to the third of five total targets between one and two hectares in size that are scheduled to be drilled before the program is completed in May, subject to weather and the onset of the spring snow melt.

LD-1 KIMBERLITE
The LD-1 kimberlite is located approximately 12 kilometres west of the Diavik Diamond Mine, and 40 kilometres northwest of Peregrine’s 71.9%-owned, nine hectare DO-27 kimberlite, which currently has an 18.2 million carat resource that is open for expansion. LD-1 was discovered when a magnetic low anomaly with a surface expression of approximately one hectare was tested by core drilling. A core hole drilled at an inclination of 50 degrees from horizontal intersected kimberlite from 76 to 168.5 metres. LD-1 is a texturally variable crater-facies volcaniclastic kimberlite that contains chrome diopside, garnet and coarse olivine.

LD-2 KIMBERLITE
The LD-2 kimberlite is located 2.5 kilometres west of the DO-27 kimberlite. LD-2 was discovered when a magnetic high anomaly with a surface expression of approximately one hectare was tested by core drilling. Angle holes were drilled into the kimberlite at inclinations of 45 and 60 degrees from horizontal from the same setup, intersecting kimberlite from 14 to 74 metres and from 20 to 110 metres, respectively. LD-2 is a black, resedimented volcaniclastic kimberlite with about 5% country rock xenoliths and contains coarse olivine and garnet.

Mr. Eric Friedland, CEO of Peregrine, said “Peregrine’s new discovery of kimberlites in Lac de Gras, a diamond district that has seen some of the most intensive diamond exploration in the world over the last 20 years, is especially gratifying and demonstrates again that we have one of the best diamond exploration teams ever assembled. Peregrine’s team has also discovered two new diamond districts in Canada since 2007, Chidliak and Nanuq, both in Nunavut, a remarkable achievement given the challenges of diamond exploration, especially in Canada’s Arctic. I anticipate that our team will make additional kimberlite discoveries as we continue our program at Lac de Gras over the next month and undertake our 2012 exploration and pre-bulk sample drill programs at our advanced Chidliak diamond project on Baffin Island.”

Samples from the LD-1 and LD-2 kimberlites will be sent to the Saskatchewan Research Council Analytical Laboratories for microdiamond testing by caustic fusion with results anticipated in the third quarter.

Peregrine’s mineral interests in the Lac de Gras district consist of 51,000 hectares of claims 100%-owned by Peregrine, 32,200 hectares of claims in joint venture with Thelon Capital Ltd. (66.2% Peregrine, 33.8% Thelon) where the LD-1 discovery was made and the 14,000 hectare WO Joint Venture (Peregrine 71.9%, Archon Minerals Ltd. 17.5% and DHK Diamonds Inc. 10.6% (Dentonia Resources Ltd. 43.37%, Kettle River Resources Ltd 43.37% and Cosigo Resources Ltd 13.26%)) where the LD-2 discovery was made. Peregrine holds 97.92% of the diamond marketing rights for the WO Joint Venture. The DO-27 kimberlite is located within the WO Joint Venture.
