Peregrine Discovers Three Separate Areas with High Concentrations of Kimberlitic Indicator Minerals on Chidliak, Baffin Island

February 19, 2008 PDF version
Mr. Brooke Clements, President and Mr. Eric Friedland, Chief Executive Officer of Peregrine Diamonds Ltd. (“Peregrine” or “the Company”) are pleased to report that the Company has discovered three separate areas with high concentrations of kimberlitic indicator minerals (“KIMs”) on the Chidliak Property (“Chidliak”), Baffin Island, Canada. Chidliak is situated approximately 150 kilometres northeast of Iqaluit, capital of Nunavut. The high concentrations of KIMs and their abrasion characteristics suggest the presence of kimberlites. Many of these indicator minerals have geochemical compositions that imply their kimberlite source contains diamonds.

On February 1st, 2008, the Nunavut Mining Recorder approved Peregrine’s application for 25 new prospecting permits that were peripheral to the existing Chidliak property, increasing its size from approximately 635,000 to 980,000 hectares.

A map showing the Chidliak property and Peregrine’s complete 2.7 million hectare land position on Baffin Island is available here.

Anomaly Areas
Peregrine collected a total of 970 till samples in 2006 and 2007, of which 286 samples, or 29 percent, contained kimberlitic indicator minerals. The full suite of KIMs have been recovered from Chidliak, including p-type pyrope garnet, eclogitic garnet, chrome diopside, picroilmenite, chromite and forsteritic olivine. Ten percent of the 2,284 p-type pyrope garnets that were analyzed by electron microprobe are classified as high-chrome, low-calcium G10 garnets. G10 garnets are commonly associated with diamond mines throughout the world.

An image showing the encouraging garnet mineral chemistry from Chidliak is available here.

The three distinct and well-defined KIM anomaly areas on Chidliak are situated 20 to 30 kilometres apart and are referred to as the Southern Anomaly, the Northern Anomaly and the Eastern Anomaly.

The largest and most significant anomalous area, the Southern Anomaly, is approximately 11 by 9 km in size and 37 of the 38 samples collected within this area were anomalous with KIMs, with most of the samples being highly anomalous. One sample contained 246 pyrope garnets, 24 eclogitic garnets, 13 chrome diopsides, 89 picroilmenites and 244 olivines. Of these mineral grains, two pyrope garnets, two eclogitic garnets, ten picroilmenites and six olivines were over 1.00 mm in size. The 0.25-2.00 mm size fraction from heavy mineral concentrates is typically recovered from till samples being analyzed for KIMs. Mineral grains larger than 1.00 mm are not common and are often a strong indication of a proximal kimberlite source.

The Northern Anomaly is roughly 13 by 2 km in size and all seven samples collected within this area are anomalous in KIMs. One sample contained 54 pyrope garnets, 11 eclogitic garnets, 35 picroilmenites, 15 chromites, 20 olivines and three chrome diopsides, of which one grain was over 1.00 mm in size.

The Eastern Anomaly measures approximately 9 by 4 km in size. All 19 samples collected within this area were anomalous in KIMs and the most significantly anomalous sample contained 96 pyrope garnets, seven eclogitic garnets, 11 picroilmenites, one chromite and 397 olivines. One of the pyrope garnets, three of the ilmenites and three of the olivines were larger than 1.00 mm in size.

All of the samples collected from Chidliak were sent to Overburden Drilling Management (“ODM”) in Nepean, Ontario for KIM and metamorphic or magmatic massive sulfide indicator mineral analyses. ODM is an internationally recognized laboratory specializing in identifying kimberlite indicator miner
