Kensington Resources Ltd.: 2004 Microdiamond Recoveries for Kimberlite 147

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 23, 2005) - Kensington Resources Ltd. (TSX VENTURE:KRT) (the "Company") announces that it has received from the operator, De Beers Canada Inc., microdiamonds results for eight coreholes targeted on Kimberlite Body 147 during the 2004-2005 program at the Fort a la Corne Diamond Project in Saskatchewan. The principal objective of the 2004-2005 program on Kimberlite 147 was to acquire representative kimberlite and diamond information for construction of a new geological model and to assess the potential for higher grade zones within the body.

"We are very pleased with the results from Kimberlite Body 147," states Robert A. McCallum, President and CEO of Kensington Resources Ltd. "A substantial number of diamonds including three larger stones were recovered indicating a high stone density and potential enrichment in this body. De Beers will utilize these results in a grade forecast, which then will enable us to make decisions on the suitability of delineation drilling and minibulk sampling for recovery of macrodiamonds."

The 147 kimberlite occurs in the main cluster of the Fort a la Corne Kimberlite Province and is located on the eastern side of the 148/147/120/220 volcanic megacluster with the 220 and 148 kimberlites situated directly to the west and southwest. Eight coreholes intersected 855.38 m of kimberlite from a total meterage of 1,740.0 m. The top of the first kimberlite intersection ranged between 96 to 106.28 m depth from surface and the bottom of the last kimberlite unit ranged from 181.22 and 221.82 m. Kimberlite thicknesses varied between 74.94 and 125.68 m.

A total of 2,432 microdiamonds were recovered from 515.20 kg of kimberlite core in 63 samples utilizing caustic dissolution methods at the Saskatchewan Research Council (SRC). Microdiamond recoveries were audited and individual stone sizes calculated by experts at the De Beers Kimberley Microdiamond Laboratory (KMDL) in South Africa. Only microdiamond data from the SRC are reported here. Summaries of diamond recovery by kimberlite drillhole and by sieve category are shown in Tables 1 and 2.

1 equals For the 2004 samples, representative sample intervals ranged
from 3.2 to 24.2 metres of kimberlite intersection; sample weights
ranged from 8.05 to 8.25 kg
2 equals Stones with at least one axis greater than 0.5 mm in length
3 equals Due to the wide variance in sample mass per historical
drillhole, the average stones/10 kg for the historical results was
weighted by the mass of individual samples (a simple average of
drillhole values was calculated at 21.4 stones/10 kg)


Microdiamond recoveries in 2004 were significantly higher than historical recoveries which are shown at the bottom of Table 1. At 47.21 stones/10kg, the average stone density of the 2004 recoveries is more than double that of the historical recoveries and is actually much higher if the 128 microdiamonds measuring less than 0.075 mm are not included in the historical tally. In comparison, fewer stones larger than 0.5 mm were recovered per kilogram of sample during the 2004 program. Microdiamonds recovered from the 2004 program will be combined with all suitable historical diamond results and submitted to Mineral Resource Management (MRM) of De Beers for grade forecasts of commercial-sized diamonds based on statistical and graphical treatment of the data.
