Tres-Or Resources Ltd. (?Tres-Or? or the ?Company?) announced commencement of a new drill program to recover macrodiamonds at the Guigues Kimberlite Pipe in southwestern Qu?bec. The drill program is contracted with Forage DCB Drilling Inc. of Rouyn-Noranda, Quebec to complete 1,500 m of HQ (64 mm diameter) core drilling. The core will provide the kimberlite for the recovery of macrodiamonds by testing at an independent Canadian laboratory. Following this drill program, Tres-Or anticipates recovering all diamonds greater than 0.450 mm in diameter, from a mini-bulk sample total weight in excess of 10 tonnes. Tres-Or's previous sampling programs at Guigues have established that the kimberlite carries closely comparable indicator mineral chemistry and microdiamond populations to De Beers' Victor Diamond Mine in northern Ontario, as well as demonstrating that more than 75% of Guigues microdiamonds lack the impurity nitrogen (Type II) similar to most of the large high value diamonds ever produced around the world. For further information, refer to Tres-Or news releases dated May 5th, April 6th, and January 5th, 2021, for details on Guigues indicator minerals, microdiamond counts, and Type II abundance. Note that although the recovery of Type II microdiamonds from the Guigues Kimberlite is suggestive of the occurrence of larger stones, this does not mean that the Guigues Kimberlite will necessarily host large Type II diamonds.
