Kensington Resources Ltd.: Microdiamond Results from 2004 Pilot Holes for Fort a la Corne Kimberlite 122

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Oct. 28, 2005) - Kensington Resources Ltd. (the "Company") (TSX VENTURE:KRT) announces more microdiamonds results received from the operator, De Beers Canada Inc. for Kimberlite Body 122 of the Fort a la Corne Diamond Project in east-central Saskatchewan. Four coreholes designated as pilot holes for large diameter drilling were sampled during the 2004-2005 program to provide additional material for diamond recoveries utilizing caustic dissolution methods. A total of 212 microdiamonds were recovered for use in grade forecasting of specific kimberlite zones. These results include the recovery of seven stones with at least one dimension greater than 0.5 mm.

"Forecast diamond grades and values from Kimberlite 122 remain very encouraging," states Robert A. McCallum, President and CEO of Kensington Resources Ltd. "Given the recently reported macrodiamond recoveries and variations within the kimberlite, additional drilling and sampling is required to better define the geology and level of confidence in the diamond size distributions within potential higher grade units of Kimberlite 122."

Representative samples totaling 309.44 kg from four HQ coreholes (2.5 inches or 63.5 mm diameter) located in the central part of the South Crater of Kimberlite 122 were submitted for diamond recovery utilizing caustic dissolution methods at the Saskatchewan Research Council (SRC) in Saskatoon. The SRC recovered and reported diamonds down to a lower sieve size cutoff of 0.075 mm.

Geological modeling of distinct kimberlite phases to date by De Beers shows the body is divisible into two main craters. Both craters are dominated by massive to graded beds of olivine/lapilli pyroclastic kimberlite (MPK-S and MPK-N) overlain by units of interbedded sediments, resedimented kimberlite, and kimberlite (UCSK-S and UCSK-N). The South Crater also has other pyroclastic kimberlite (OPK) units of limited areal extent including OPK-13, a different kimberlite type identified only in corehole 04-122-013. A total of 195.62 kg of MPK-S kimberlite was tested from core intervals in drillholes 04-122-012A, 04-122-014, and 04-122-019 as well as 113.82 kg of OPK-13 from drillhole 04-122-013.

The average microdiamond abundance for all pilot hole samples is 6.9 stones per 10 kg. The average microdiamond abundance for MPK-S in the pilot holes is 3.9 stones per 10 kg compared to 6.1 stones per 10 kg from previous results in this kimberlite unit. One explanation may be that sampling of some 73.4 kg of the total mass occurred below a depth of 275 metres in coreholes 04-122-014 and 019. These deep intervals range from very fine-to medium-grained kimberlite and may represent a different kimberlite unit from the rest of the MPK-S above. Notably, the 11.9 stones per 10 kg for OPK-13 may indicate the presence of a more prospective sub-unit within the main kimberlite phase of the south crater, of which the size and extent must be further investigated. Results from 2004 will be combined with historic diamond recoveries to produce higher confidence grade forecasts for individual kimberlite units.

Additional summaries of diamond recovery results, information, and maps are available on the Company's website at A more detailed summary of the 122 geology was given in the Company's news release of May 21, 2004.
