Type II micro-diamonds dominate Tres-Or Resources’ Guigues pipe

Tres-Or Resources (TSXV: TRS) announced that after an analysis conducted by the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services (SRC), it was determined that Type II micro-diamonds lacking measurable nitrogen dominate at the company’s Guigues Kimberlite pipe in southwestern Quebec. 

In a press release, Tres-Or said that the nitrogen measurements were conducted on all Guigues +0.150 mm microdiamonds, using the industry-standard technique of micro-Fourier Transform Infrared Spectroscopy.

Guigues was the first kimberlite pipe discovered in eastern Canada

In total, SRC reported 14 out of the 17 +0.150 mm micro-diamonds lacked detectable nitrogen (zero parts per million), and thus are considered to be the highly desirable Type II. 

Type II diamonds are rare, with less than 2% of the gems sold worldwide fitting into this category. They are, however, sought after because many of the largest, highest quality gem diamonds ever recovered lack nitrogen.

“Tres-Or is excited to learn that Type II micro-diamonds dominate our samples. This positive factor, along with the microdiamond counts themselves, the strong diamond indicator mineral chemistry and the site’s excellent access and infrastructure are moving our Guigues diamond project forward towards our first macro-diamond tests, which we hope to announce in the near future,” Laura Lee Duffett, the company’s CEO, said in a media statement.

The Guigues kimberlite claims are located in southwestern Quebec, in the Notre Dame du Nord area. The project was initially explored by De Beers in 1983, and it was the first kimberlite pipe discovered in eastern Canada.
