Macrodiamond Drill Program Completed at Tres-Or's Guigues Pipe in Quebec

Tres-Or Resources Ltd. (TSXV: TRS) (OTC Pink: TRSFF) ("Tres-Or" or the "Company") is pleased to report completion of the Company's first macrodiamond drill program at the Guigues Kimberlite Pipe in southwestern Québec. The planned 5 holes have been completed to 300.00 m each, providing more than 10 tonnes of kimberlite sample for mini-bulk macrodiamond testing. Four of the holes ended in kimberlite at 300.00 m, and the fifth hole entered metasediment county rock at 262.10 m. The drill was operated 24 hours a day by Forage DCB Drilling Inc. of Rouyn-Noranda, Quebec and finished the entire 1,500 m of HQ (64 mm diameter) core program in one week.

Drill holes completed:

TR-21-01: northern set-up, vertical to 300.00 m to end of hole in kimberlite. Top of kimberlite at 33 m.

TR-21-02: northern set-up, inclined 80° south (azimuth 180°) to 300.00 m at end of hole. Country rock metasediments encountered at 262.10. Top of kimberlite at 33.75 m.

TR-21-03: central set-up, vertical to 300.00 m to end of hole in kimberlite. Top of kimberlite at 47.90 m.

TR-21-04: southwestern set-up, vertical to 300.00 m in kimberlite. Top of kimberlite at 51.25 m.

TR-21-05: southwestern set-up, inclined 80° north (azimuth 360°) to 300.00 m in kimberlite at end of hole. Top of kimberlite at 51.10 m.

The kimberlite core will provide the sample for the recovery of macrodiamonds by testing at an independent Canadian laboratory. Following this drill program, Tres-Or anticipates recovering all diamonds greater 0.425 mm in diameter, from a mini-bulk sample total weight in excess of 10 tonnes. Already, approximately 8 tonnes have been collected during this drill program.

Logging of the core was completed on the Timiskaming First Nations Reserve in Notre Dame du Nord, and supports multiple intrusive phases of kimberlite, each with the potential or carrying a different concentration of macrodiamonds.

Tres-Or's previous sampling programs at Guigues have established the kimberlite carries closely comparable indicator mineral and microdiamond populations to De Beers' Victor Diamond Mine in northern Ontario, as well as demonstrating that more than 75% of the Guigues microdiamonds lack the impurity nitrogen (Type II) similar to most of the largest high value diamonds ever produced around the world. For further information, refer to Tres-Or news releases dated May 5^th, April 6^th, and January 5^th, 2021, for details on Guigues indicator minerals, microdiamond counts, and Type II abundance.

[Note: Type II diamonds are defined as lacking nitrogen; they are equivalent to Type IIa diamonds which are additionally defined as lacking trace boron impurities which results in a blue color, such as the famous Hope diamond. Nitrogen measurements were conducted by the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services ("SRC") on all Guigues +0.150 mm microdiamonds, using the industry-standard technique of micro-Fourier Transform Infrared Spectroscopy (FTIR). SRC does not report boron, thus all analyses lacking nitrogen are reported as Type II.]

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.
