Kensington Resources Ltd.: Another Large Diamond From Fort A La Corne Kimberlite 140/141-4.09 Carat Diamond Recovered From Drillhole 04-140-044
Business Wire - March 21, 2005 09:01
VANCOUVER, British Columbia, Mar 21, 2005 (BUSINESS WIRE) -- Kensington Resources Ltd. (the "Company") (TSX VENTURE:KRT) announces the recovery of 160 macrodiamonds weighing 21.06 carats, including a 4.09 carat stone, from large diameter drillhole 04-140-044 targeted on Fort a la Corne Kimberlite 140/141 drilled during the 2004 Evaluation Program.
The total estimated mass of kimberlite excavated from 04-140-044 was 186.29 tonnes of which 94.36 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.
"Relatively small minibulk samples from the Breccia Beds in the southern part of Kimberlite 140/141 have provided significant numbers of diamonds in the coarser size fractions and the 4.09 carat stone recovered in this drillhole provides additional sharp emphasis on the large stone potential that this higher-grade zone is predicted to deliver," commented Robert McCallum, President and CEO of Kensington Resources Ltd.
Large stone recoveries in drillhole 04-140-044 included an estimated 14 diamonds greater than 0.25 carat in size with a combined weight of 9.58 carats. These 14 diamonds, or some 8.8% of the total number of stones, account for 45.5% of the carat weight of the parcel. The 4.09 carat stone was recovered from the 118 to 130 metre interval within the upper part of the kimberlite body. The quality and value of this stone will be determined by De Beers' experts in due course. The size distribution of the recovered diamonds from this drillhole is shown in Table 2.

(i)An additional 2 stones weighing a cumulative 0.015 carats were

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 04-140-044 are the second 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 www.kensington-resources.com.
