[{"type":"text","content":"Tres-Or Announces Type II Microdiamonds Dominate at the Guigues Kimberlite Pipe in QuebecVancouver, British Columbia--(Newsfile Corp. - April 6, 2021) -  Tres-Or Resources Ltd. (TSXV: TRS) (OTC: TRSFF) (\"Tres-Or\" or the \"Company\") is pleased to announce Type II microdiamonds lacking measurable nitrogen dominate at the Guigues Kimberlite pipe in southwestern Quebec. The 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). In total, SRC reports 14 out of the 17 +0.150 mm microdiamonds lacked detectable nitrogen (zero parts per million - 0 ppm), and thus are the highly desirable Type II. Type II diamonds are rare (less than 2% of gems sold) but highly desirable because many of the largest, highest quality gem diamonds ever recovered lack nitrogen (refer to Tres-Or news release dated December 8, 2020). \"Tres-Or is excited to learn that Type II microdiamonds dominate our samples. This is another positive factor, along with the microdiamond counts themselves, strong diamond indicator mineral chemistry and the site's excellent access and infrastructure that are moving our Guigues Diamond Project forward towards our first macro-diamond tests, which we hope to announce in the near future,\" says Laura Lee Duffett CEO of Tres-Or Resources Ltd. SRC reports that the other 3 microdiamonds +0.150 mm-contain between 365 and 949 ppm nitrogen apiece, and are dominated by the \"A\" nitrogen crystal lattice defect suggesting relatively shallow mantle residence depths (SRC estimates between 150 and 165 km, using a 40 mW/m2 geotherm).
