PRELIMINARY RESULTS FROM MICROPROBE EVALUATION OF THE GUIGUES KIMBERLITE PIPE, QUEBEC

Tres-Or Resources Ltd. is releasing a report on a preliminary microprobe evaluation of the Guigues kimberlite near Notre Dame du Nord, Que. Microprobe analyses from kimberlite indicator minerals (KIMs) recovered from three reverse circulation (RC) drill holes completed at the Guigues pipe have returned eclogite garnets comparable with most inclusions in diamond. These eclogite garnets with diamond inclusion compositions were recovered from each sample, but with noticeably greater abundance in the central and southern parts of the pipe.

Most other indicator minerals exhibit little variation between samples, although the chromites are more encouraging from the central part of the pipe. The most chromium-rich at 64.72 per cent Cr2O3 comes from the central pipe sample and it is also manganese-rich, similar to chromite included in diamond. Three other chromites with greater than 61.0 per cent Cr2O3 and somewhat lower MgO are comparable with chromite intergrown with diamond.

The sampling program was designed to recover indicator mineral suites from different parts of the kimberlite pipe and the immediately overlying till for analysis by electron microprobe, with the goal of identifying favourable kimberlite phases for microdiamond testing. The KIM grains analyzed were recovered from samples collected from a RC drilling program carried out on its wholly owned Guigues kimberlite in October, 2009 (see news release in Stockwatch dated Oct. 28, 2009).

The Guigues kimberlite is part of Tres-Or's Quebec diamond property and was reportedly discovered in 1983 by De Beers, before its discovery of the Victor kimberlite near Attawapiskat in Northern Ontario in 1987. The Guigues claims were dropped well before De Beers returned to Victor and conducted more intense testing which proved to be Ontario's first diamond mine. No comprehensive microdiamond testing using modern caustic fusion processes is known to have been attempted at Tres-Or's Guigues kimberlite.

Given the recovery of encouraging eclogite garnets with diamond inclusion compositions, and the potential of high-quality diamonds as suggested by production from the Victor mine within the same Superior craton, Tres-Or believes the Guigues kimberlite merits direct testing for microdiamonds. The primary goal for the recommended drill program is to recover NQ drill core from the most prospective parts of the pipe suitable for caustic fusion tests at a modern independent Canadian microdiamond laboratory.
