VICTORIA, British Columbia, Mar 07, 2005 (BUSINESS WIRE) -- Kensington Resources Ltd. (the "Company") (TSX VENTURE:KRT) is pleased to announce the recovery of a large, clear, colourless, macrodiamond from samples extracted from Kimberlite 140/141 that was drilled in the 2004 Evaluation Program.

A large diamond measuring approximately 1.4 x 1.0 x 0.75 cm was recovered during diamond recovery procedures at the De Beers Group Exploration Diamond Laboratory in Johannesburg, RSA. The colourless stone is clear of significant inclusions and therefore appears to be of high quality. Formal valuation of the stone will be conducted by De Beers' experts as soon as possible. The 10.53 carat diamond was recovered in large diameter drillhole 04-140-051 along with five other macrodiamonds including a 1.32 carat stone from a sample covering depth interval 118 to 130 metres, only 18 metres beneath the overlying glacial overburden.

This sample is from the upper portion of the kimberlite breccia beds of the southern, higher-grade unit of 140/141 which was targeted with five large diameter drillholes designed to increase the level of confidence in grade forecasts and to provide preliminary valuations for revenue modeling by De Beers experts. Diamond recoveries for the remaining samples in this drillhole will be reported as soon as the results are received by the Company.

Robert McCallum, President of Kensington Resources Ltd., remarked, "We have already seen significant evidence from minibulk sampling that supports the presence of a large stone population in the 140/141 kimberlite, including a 10.23 carat stone recovered in the 2002 program. Discovery of this 10.53 carat diamond, the largest stone yet recovered by the Fort a la Corne Joint Venture, provides further support that the large diamonds can be of high quality, as well."

Photographs of the 10.53 carat diamond and a map of the 140/141 kimberlite with drillhole placements are posted on the Kensington Resources Ltd. website at www.kensington-resources.com.
