Kensington Resources Reports on Drilling Progress; 2005 Core Drilling Program Nearing Completion

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 12, 2005) - Kensington Resources Ltd. (the "Company") (TSX VENTURE:KRT) reports on drilling progress at the Fort a la Corne Diamond Project in Saskatchewan. A total of 103 HQ core holes (diameter of 2.5 inches or 63.5 mm) with kimberlite intersections totaling 9,179.01 metres have been completed on thirteen high interest, prioritized kimberlite bodies including the western part of the Star Kimberlite. Additionally, two core holes intersected 151.63 metres of kimberlite drilled for hydrogeological testing on Kimberlites 140/141 and 150. A total of 134 HQ core holes are planned as part of the 2005 program, which is budgeted at CDN $25.6 million.

"The 2005 core drilling program is on schedule and nearing completion. This extensive program was designed to methodically drill each of the kimberlite bodies within the southern cluster that had shown promise in previous drilling programs. Already, a number of kimberlite intersections recovered this year exhibit coarse-textured rock which is of great interest to us," comments Robert A. McCallum, President and CEO of Kensington Resources Ltd. "This includes some of the holes in the western extension of the Star Kimberlite body."

"We can look forward to the recovery of microdiamonds from the most prospective core samples by the Saskatchewan Research Laboratory. Good results will be identified and those units will be advanced to delineation drilling and, if warranted, to subsequent mini-bulk evaluation."

Project Update Highlights

The current budgeted project activity represents work toward the first phase of the Advanced Exploration and Evaluation (AE&E) Plan. This phase will consist mainly of geological drilling and microdiamond analysis to determine the internal geology and grades of the targeted kimberlites. These results will be used by De Beers to develop a model to help predict the grades that could be seen in a commercial production scenario and to assist in modeling average diamond values once a sufficient parcel of macrodiamonds is obtained.

Drilling continues with three Boart-Longyear LF-70 core rigs operating on 24 hour schedules. Two of the LF-70 rigs have been converted to helicopter-portable configurations in order to drill on wet surface areas within Kimberlites 123, 223, 152, and the west extension of the Star. The drill program remains on schedule and is 80% complete. Table One summarizes drilling results to August 31, 2005. The expected final meterage for the current phase of drilling will be reached near the end of September.

Core hole STR-05-003C, located 70 metres west of the Star shaft, intersected 612.0 metres of kimberlite in a hole that was terminated at a total depth of 699 metres while still in kimberlite. The core hole was centered on a deep-going part of the body that is interpreted to be a major feeder vent for the volcanic complex. Two main phases of kimberlite were encountered with a thicker unit extending from 108.15 metres to a depth of at least 395 metres, the base of core examined to date. Preliminary description of the core indicates the unit is generally medium-grained with common indicator minerals. It appears that this hole is quite different from other core holes drilled by the Joint Venture on the Star Kimberlite and the dominant rock unit appears to have characteristics represented in both the Early Joli Fou and Late Joli Fou kimberlite phases. Further geological logging of this core and comparison to other drill holes will be conducted by the operator once all of the holes targeted on the Star Kimberlite are completed.

Drilling has commenced on Kimberlite 123, the highest priority body in the 2005 program, and prospective core samples will be sent to the Saskatchewan Research Laboratory for diamond recovery as soon as drilling and core description protocols are completed.
