  • Macrodiamond Drill program ready to start at Tres-Or’s (TRS) guigues pipe in Québec
  • The drill program is contracted with Forage DCB Drilling Inc. of Rouyn-Noranda, Québec to complete 1,500 m of HQ core drilling
  • The core will provide the kimberlite for the recovery of macrodiamonds by testing at an independent Canadian laboratory
  • Tres-Or’s previous sampling programs at Guigues have established that the kimberlite carries closely comparable indicator mineral chemistry

Tres-Or Resources Ltd. (TRS) is starting a new drill program to recover macrodiamonds at the Guigues Kimberlite Pipe in southwestern Québec.

The drill program is contracted with Forage DCB Drilling Inc. of Rouyn-Noranda, Québec 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 per cent of 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, April 6, and January 5, 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 that result in blue colour, 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.

Tres-Or Resources Ltd. is a Canadian resource company focused on exploring diamonds and gold resources in the Témiscamingue and Abitibi regions of Québec and is listed on the TSX Venture Exchange under the trading symbol “TRS”.

Tres-Or Resources Ltd. (TRS) is up 5.88 per cent, trading at C$0.09 at 10:49 am ET.
