Vancouver, British Columbia, Canada - Tuesday, December 4, 2007 - Peregrine Diamonds Ltd. (TSX-PGD) (“Peregrine”) is pleased to announce additional microdiamond results from the plus five hectare Kayuu kimberlite pipe which confirm the diamond potential of the newly discovered kimberlite field at the Nanuq property, Nunavut, Canada.

A total of 194 diamonds (>0.075mm) were recovered from this latest aliquot of 253.35 kilograms of kimberlite. This is in addition to the recovery of 819 diamonds previously reported (see press release dated November 22, 2007). In all, a total of 1,013 diamonds (>0.075mm) were recovered from the processing of 1,558 kilograms of kimberlite with the largest stone described as a white fragment measuring 2.12 mm X 1.48 mm X 1.0 mm.

The table below summarizes the complete set of results received for the samples submitted from the three kimberlite pipes currently known at Nanuq.
