Kensington Resources Ltd.: Higher Grade Diamond
Results For Drillhole 04-140-052 From Fort A La Corne
Kimberlite 140/141

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 22, 2005) - Kensington
Resources Ltd. (the "Company") (TSX VENTURE:KRT) announces the recovery
of 90 macrodiamonds weighing 17.51 carats, including a 1.39 carat stone,
from large diameter drillhole 04-140-052 targeted on Fort a la Corne
Kimberlite 140/141 drilled during the 2004 Evaluation Program.

The total estimated mass of kimberlite excavated from 04-140-052 was
132.14 tonnes of which 105.24 tonnes of material greater than 1.5 mm in
size were retained for macrodiamond recoveries. Minibulk samples were
shipped to the De Beers' dense media separation plant located in Grande
Prairie, Alberta for the first stage of diamond recovery procedures,
followed by final diamond recovery in an ultra-high security facility in
Johannesburg, RSA. A summary of sampling information and diamond
recovery results for this drillhole is shown in Table 1.

(1) The calculation of theoretical mass was based on the volume of a
vertical cylinder and a kimberlite rock density of 2.21.
(2) Diamond weights were provided in terms of total carats per sieve
class. The reader is cautioned that for interval samples
(12 metres) with multiple stone recoveries, the number of stones
greater than 0.25 carats was estimated by dividing carat weight
by the number of stones in the +9 sieve class for selected
samples and all of the +11 and larger sieve classes.

Large stone recoveries in drillhole 04-140-052 included an estimated 17
diamonds greater than 0.25 carat in size with a combined weight of 11.13
carats. These larger diamonds account for 63.6% of the total carat
weight, but represent only 18.9% of the total stones in the parcel.
Eleven of the 17 larger diamonds were recovered from samples taken from
the upper 50 metres of the kimberlite body. The size distribution of the
recovered diamonds from this drillhole is shown in Table 2.

"The higher grade of this minibulk sample with a large proportion of
larger stones is likely to affect the modeled grade results for the
Breccia Beds in a positive way," commented Robert McCallum, President
and CEO of Kensington Resources Ltd.

The 2004 Evaluation Program (CDN $7.6 million) included ten large
diameter minibulk drillholes positioned on high-grade zones in
kimberlites 140/141 and 122. Samples and results from drillhole
04-140-052 are the third of five batches that were recovered from
Kimberlite 140/141 breccia beds and related kimberlite units during the
2004 Evaluation Program. Minibulk samples collected in this program will
provide additional diamonds that will be used to increase the level of
confidence in grade forecasts, and for revenue modeling by De Beers'
experts. A recently revised map of kimberlite body 140/141 showing
location of the 2004 drillholes is posted on the Kensington Resources
Ltd. website at
