Kensington Resources Ltd.: Diamond Results for
Drillhole 04-140-045 from Fort A La Corne Kimberlite

VICTORIA, BRITISH COLUMBIA--(CCNMatthews - March 8, 2005) - Kensington
Resources Ltd. (the "Company") (TSX VENTURE:KRT) announces the recovery
of 135 macrodiamonds weighing 15.445 carats from large diameter
drillhole 04-140-045 targeted on Fort a la Corne Kimberlite 140/141
drilled during the 2004 Evaluation Program.

The total estimated mass of kimberlite excavated from 04-140-045 was
139.72 tonnes of which 103.38 tonnes of material greater than 1.5 mm in
size were retained for macrodiamond recoveries. Minibulk samples were
shipped to 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. Samples and results from drillhole 04-140-045 are the
first fully processed batch of many that encompass the 2004 Evaluation
Program. 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 total carat weight by the
number of stones in the +11 and larger sieve classes.

Large stone recoveries in drillhole 04-140-045 included an estimated
sixteen diamonds greater than 0.25 carat in size with a combined weight
of 6.845 carats. These 16 stones, or some 11% of the total number,
account for 44% of the carat weight of the parcel. The size distribution
of the recovered diamonds from this drillhole is shown in Table 2.

"The recovery of significant numbers of diamonds in the coarser size
fractions from this drillhole sample will contribute substantially to
improving confidence levels in the grade estimate and modeled value for
the breccia beds of the southern 140/141 kimberlite body," commented
Robert McCallum, President of Kensington Resources Ltd. "These initial
results strongly support the previously forecasted potential of the
140/141 kimberlite by De Beers."

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. Five targets were located on the south
140/141 breccia beds and related kimberlite units to collect additional
diamonds that will be used to increase the level of confidence in grade
forecasts, and for revenue modeling by De Beers' experts. A map of
kimberlite body 140/141 showing location of the 2004 drillholes is
posted on the Kensington Resources Ltd. website at

Full diamond results for large diameter drillhole 04-140-051, including
the recently announced 10.53 carat stone, will be released as soon as
they are completed and received from the operator, De Beers Canada Inc.
