Kensington Resources Ltd.: 2002 Large Diameter Drilling Program Completed At Fort a la Corne
VICTORIA, British Columbia--(BUSINESS WIRE)--Dec. 24, 2002
Kensington Resources Ltd. (the "Company") (TSXV:KRT) is pleased to announce a summary of drilling information from the large diameter drilling program recently completed for the Fort a la Corne Joint Venture Diamond Project, located in east-central Saskatchewan.
Evaluation of the preliminary 2001 results during July, 2002 enabled planning and implementation of a drilling and sampling program for the fourth quarter of 2002. While diamond recoveries from the 2001 program were less than expected, the large stone potential, encouraging diamond valuations, and very large estimated size of the 140/141 body made this kimberlite attractive for continued evaluation. Combining a lack of understanding of 141 geology and diamond distribution, as well as low levels of testing, with positive initial indications gave impetus to mount a CAN$ 5.2 million dollar, two-stage drilling program in 2002. The 2002 program was focused on improving the understanding of geology and diamond distribution within the combined 140/141 body with a goal of ultimately proving up resource tonnage. To this end, 23 coreholes were targeted on several parts of the combined body in order to provide useful geological information concerning the layering and extent of kimberlite phases.
Reverse Circulation Drilling and Kimberlite Sample Tonnages for 2002
Three very large diameter drillholes (914.4 mm or 36 inch) were targeted on the central part of the northwest eruptive centre in order to maximize recovery of diamonds to improve confidence levels for diamond valuations in this part of the body. Each of the three drillholes were spotted within 15 metres of a centrally located NQ corehole (141-29) that was drilled in 2002 to permit better understanding of the kimberlite intersection, which provided the best macrodiamond recoveries in 2000 (large diameter drillhole 141-04).
Subsequent to core drilling, several of the most prospective kimberlite intersections were identified for minibulk sampling by large diameter (609 mm or 24 inch) reverse circulation, mud-flood with air-assist drilling methods, which were conducted from September 29 to November 22, 2002. Five favourable locations were chosen predominantly from the sparsely-tested southeastern and central portions of the combined 140/141 body, however, only four were tested due to the premature loss of hole integrity in 140-28 causing the hole to be re-drilled at the expense of the fifth target. Drilling and sampling information for all eight large diameter boreholes is shown in Table 1.
Diamond recovery from the 2002 samples is currently in progress and De Beers has indicated that initial stone counts and sieve parcel weights may be anticipated from April of 2003. Ongoing evaluation of the 140/141 kimberlite will continue in the meantime and includes the first draft of a Conceptual Modeling Study conducted by AMEC (an engineering firm) and qualified De Beers personnel, which is expected to be made available to the Joint Venture partners in January 2003.
