Peregrine Discovers Third Kimberlite This Year at Lac de Gras, Canada07:30 EDT Tuesday, April 24, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 24, 2012) - Peregrine Diamonds Ltd. ("Peregrine" or "the Company") (TSX:PGD) is pleased to report that it has discovered a third kimberlite this year in the Lac de Gras region, Northwest Territories, Canada. The kimberlite, named LD-3, was discovered at the third of four land-based geophysical targets drilled during the winter program. 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 LD-3 kimberlite is located on a claim that is 100%-owned by the Company, approximately seven kilometres southwest of Peregrine's 72.0%-owned DO-27 kimberlite. DO-27 currently has an 18.2 million carat resource that is open at depth. LD-3 was discovered when a circular electromagnetic anomaly with a surface expression of approximately one hectare was tested by core drilling. A hole drilled at an inclination of 45 degrees from horizontal intersected kimberlite from 30 to 98 metres. LD-3 is a dark green to black volcaniclastic kimberlite with abundant coarse olivine, garnet and chrome diopside.A fourth target was drilled without intersecting kimberlite, and drilling of a fifth target was not initiated based on the drilling results from the fourth target. The drilling program has now concluded. On April 16, 2012, Peregrine announced the discovery of the first two kimberlites at Lac de Gras this year, LD-1 and LD-2. Samples from the three kimberlites will be sent to the Saskatchewan Research Council Geoanalytical Laboratories for microdiamond testing by caustic fusion with results anticipated in the third quarter.Commenting on the discoveries, Mr. Brooke Clements, President of Peregrine, said, "We drilled four targets and discovered three kimberlites, an excellent success rate for our world-class exploration team. The close proximity of these kimberlites to the Diavik Diamond Mine and to our DO-27 diamond deposit will be important if they are proven to have economic potential. For the balance of 2012, our exploration team will be focussed on advancing our 100%-owned Chidliak diamond project on Baffin Island." In addition to 51,000 hectares of claims 100%-owned by Peregrine, the Company's mineral interests in the Lac de Gras district also consist of 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 where the LD-2 discovery was made. The WO Joint Venture consists of Peregrine 72.0%, Archon Minerals Ltd. 17.5% and DHK Diamonds Inc. 10.5% (DHK Diamonds Inc. consists of Dentonia Resources Ltd. 43.37%, Kettle River Resources Ltd. 43.37% and Cosigo Resources Ltd. 13.26%). 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.Peregrine Receives Corporate Award in NunavutOn April 19, 2012, Peregrine received the 2012 Canadian North Murray Pyke Corporate Award at the Nunavut Mining Symposium. This award recognizes the contributions of Peregrine to the economic and social development of Nunavut.Receiving the award on behalf of the Peregrine team in Iqaluit, Mr. Brooke Clements commented, "This award is quite an honour and a tribute to the hard work and dedication of our entire team since the project began in 2005.
