PEREGRINE DIAMONDS LTD.: DO-27 BULK SAMPLE PROCESSING TO BEGIN APRIL 30, 2007

BHP Billiton's Ekati diamond mine sample plant will begin processing Peregrine Diamonds Ltd.'s 2007 bulk sample from the plus-nine-hectare DO-27 kimberlite pipe, WO diamond project, Northwest Territories, Canada, on April 30, 2007.

The 2007 large diameter reverse circulation drilling (LDRC) bulk sample program has recovered approximately 2,420 wet tonnes of kimberlite to date, with drilling still continuing. The kimberlite has been collected in 1,586 individual sample bags from 26 large diameter drill holes. The samples have been transported to Ekati for processing.

In addition to providing substantially more diamonds for valuation, the processing will supply additional information regarding the diamond grade and diamond distribution within DO-27.

The sample processing plant will operate on a 24-hour-per-day, seven-day-per-week basis, with completion, including the picking and sorting of all the diamonds, anticipated in August, 2007.

Jennifer Pell, PhD, PGeo, chief geoscientist for Peregrine, is the qualified person under National Instrument 43-101 for the WO diamond project.

We seek Safe Harbor.
