Kensington Resources Ltd.: Favourable Microdiamond Results for Kimberlite 122
VICTORIA, British Columbia--(BUSINESS WIRE)--May 21, 2004
The Board of Directors of Kensington Resources Ltd. (TSX VENTURE:KRT) (the "Company") is pleased to report new microdiamonds results and a preliminary geological model for Kimberlite Body 122 of the Fort a la Corne Diamond Project in east-central Saskatchewan. Microdiamond results were recently received from the operator, De Beers Canada Exploration Inc. for work completed by the Saskatchewan Research Council (SRC). Results from the 2003 core drilling and sampling program clearly show an improvement of microdiamond abundances compared to historical recoveries for this body. Kimberlite Body 122 is one of the largest bodies in the Fort a la Corne field with a footprint of 100+ hectares (based on a 30-metre modeled thickness cutoff).
A total of 327 microdiamonds were recovered utilizing caustic dissolution methods from 412.65 kilograms of core submitted to the SRC (Table 1). Representative slabbed core samples were collected from 11 HQ coreholes widely spaced across the 122 body. Six of these stones have at least one dimension exceeding 0.5 mm in length and are considered to be macrodiamonds. The SRC recovered and reported diamonds down to a lower cutoff of 0.075 millimetres in size; diamonds passing through a 0.075 mm screen were not included in the stone tallies.
Initial geological modeling of distinct kimberlite phases by De Beers, based on drill core from Kimberlite 122 shows the body is divisible into two main craters, and a subordinate third area based on relatively sparse information. The northern crater is dominated by massive to graded beds of olivine/lapilli pyroclastic kimberlite (MPK-N) overlain by interbedded sediments, resedimented kimberlite, and kimberlite (UCSK-N).
Similarly, the south crater is dominated by variably massive to bedded, fine-grained to coarse-grained, olivine/lapilli pyroclastic kimberlite (MPK-S) partially overlain by a cap of interbedded sediments and resedimented kimberlite (UCSK-S) on its' northern fringe. Other pyroclastic kimberlite (OPK) dominates the kimberlite intersection at drillhole 03-122-10, but the overall kimberlite intersection here has attenuated to 28.9 metres from a thicker interval of 53.4 metres in drillhole 03-122-09. One unit of other pyroclastic kimberlite (OPK-S1) forms a small pod near the centre of the southern crater. Drillhole 03-122-07 is the only intersection that has a basal unit of interbedded sediments and kimberlite (SAK). The order of emplacement for the individual kimberlites and their contact relationships within, and between, the two main parts of body 122 are not fully understood at this time.
The north sector of Kimberlite 122 had total recovery of 133 stones, of which 2 macrodiamonds had at least one dimension greater than 0.5 mm. Most of the stones were recovered from the MPK-N kimberlite phase producing the best average stone abundance of 9.8 stones/10kg. The overlying UCSK-N gave an average abundance of 7.5 stones/10kg based on recovery of 18 stones from a much smaller sample mass. Table 1 shows the recovery of stones by kimberlite type and area.
By comparison, the south sector returned lesser stone abundances of 7.3 and 3.9 stones/10kg for the MPK-S and UCSK-S phases, respectively. The MPK-S unit had four macrodiamonds with at least one dimension greater than 0.5 mm. OPK-S1 in the southeastern part of the body returned an average value of 8.0 stones/10kg based on the recovery of 26 stones from 32.40 kg of sample.
