Peregrine Discovers Kimberlite at Chidliak, Baffin Island; Estimated Kimberlite Size: Six Hectares

VANCOUVER, BRITISH COLUMBIA, Jul 23 (MARKET WIRE) --
Mr. Brooke Clements, President and Mr. Eric Friedland, Chief Executive
Officer of Peregrine Diamonds Ltd. (TSX: PGD) ("Peregrine" or "the
Company") are pleased to report the discovery of a new kimberlite on the
Chidliak property ("Chidliak"), Baffin Island, Nunavut, Canada. A
kimberlite outcrop was discovered within a circular magnetic anomaly
selected from an airborne geophysical survey that commenced on July 17,
2008. The anomaly has an estimated surface expression of six hectares.
The outcrop was discovered in an area with high concentrations of
kimberlite indicator minerals ("KIMs"). As reported in a news release on
February 19, 2008, many of these indicator minerals have geochemical
compositions that imply their kimberlite source contains diamonds.
Chidliak is situated approximately 150 kilometres northeast of Iqaluit,
capital of Nunavut. The proximity to the capital provides the Chidliak
project with better infrastructure support than is available in other
more remote regions of Nunavut.

A sample of approximately 200 kilograms collected from the kimberlite
outcrop has been shipped to Saskatchewan Research Council Geoanalytical
Laboratories for microdiamond recovery by caustic fusion. Results of the
analyses are expected in August.

Mr. Peter Holmes, Peregrine's Vice President, Exploration stated, "This
is a significant discovery in a brand new area; the nearest known
kimberlites are approximately 700 kilometres to the east in Greenland.
The fact that the discovery was made after only the fourth day of the
airborne geophysical survey provides optimism that this is the first of
many kimberlite discoveries to be made. We have now proven that there is
good tonnage potential in this new district and the encouraging mineral
chemistry on the property suggests that some of the kimberlites could be
significantly diamondiferous."

Brooke Clements, President of Peregrine, stated, "This discovery, coupled
with the discovery of a new diamond district on the Nanuq property in the
eastern Arctic region of Nunavut in July 2007, puts Peregrine in a unique
position among junior diamond explorers in the world. Peregrine currently
controls 100% interests in Nanuq and Chidliak and it is truly early days
in the evaluation of the diamond potential of these two new districts. We
look forward to continued encouraging results. The discoveries at Nanuq
and Chidliak are the result of the hard work, dedication and technical
expertise of the Peregrine staff and the efforts of many contractors."

Description of Kimberlite Discovery and 2008 Chidliak Work Program

On July 17, 2008, Fugro Airborne Surveys Corporation initiated a 9,000
line kilometre heli-borne magnetic/electromagnetic survey flown at a 100
metre line spacing. The survey was designed to cover the most prominent
KIM anomalies that have been identified on the property. 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. Peregrine's geophysicist, Maiko
Sell is in the field interpreting the survey data on a real-time basis.
On July 20, 2008, after the fourth day of surveying, a large circular
magnetic anomaly, approximately 250 metres in diameter, was selected from
the survey data for follow-up on the ground. Mr. Sell and Project Manager
Hugo Grenon visited the anomaly and immediately discovered an outcrop of
weathered kimberlite measuring three metres by five metres. Abundant
kimberlite cobbles are present in the soil away from the outcrop within
the boundaries of the anomaly. The kimberlite from the outcrop is
described as being magmatic with abundant olivine macrocrysts, some up to
10 mm in size. Abundant mauve-colored pyrope garnet and chrome diopside
are present and both ilmenite and chromite were tentatively identified.
An altered peridotite xenolith was also observed.

Three maps, an image showing the encouraging garnet mineral chemistry
from Chidliak, and several photographs of the kimberlite discovery are
available at http://www.pdiam.com/i/pdf/chidliak.pdf.

The Chidliak airborne survey is scheduled to be completed in mid-August,
2008. The field crew will continue to investigate high count KIM
anomalies at Chidliak and geophysical anomalies chosen from the survey,
in an effort to make additional kimberlite discoveries this year.
Peregrine expects to generate many targets from the airborne survey and
preparations are underway for a drill program to be initiated in the
summer of 2009.

In addition to its diamond potential, the Chidliak property also hosts
strong platinum and base metal anomalies as described in a Peregrine news
release issued on February 28, 2008. Highly anomalous concentrations of
the platinum-bearing mineral sperrylite, the zinc-bearing mineral gahnite
and the copper-bearing mineral chalcopyrite were recovered from till
samples collected in 2007. A four-person crew has initiated a follow-up
program on the metals anomalies that includes prospecting, geologic
mapping, geochemical sampling and ground geophysics.

Alliance with BHP Billiton

The Chidliak property is owned 100% by Peregrine, subject to certain
back-in rights held by BHP Billiton. After Peregrine has incurred a
minimum of $3 million and up to $10 million of expenditures on the
property, BHP Billiton has a one-time option to elect to acquire a 51%
interest in the property by sole-funding five times the exploration
expenditures that have been incurred ($15 million to $50 million). To
date, Peregrine has incurred an estimated $2.2 million in expenditures on
the property. BHP Billiton has the right to earn an additional seven
percent interest in the property by sole-funding the complete costs of a
bankable feasibility study. If this option is exercised, the resulting
ownership interests in any potential mine would be BHP Billiton 58% and
Peregrine 42%.

Mr. Peter Holmes, P. Geo., Peregrine's Vice President, Exploration, is a
Qualified Person under NI 43-101 and is responsible for the design and
conduct of the programs carried out by the Company on the Chidliak
property.
