# Tres-Or Announces Type II Microdiamonds Dominate at the Guigues Kimberlite Pipe in Quebec Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/tres-or-announces-type-ii-microdiamonds-dominate-at-the-guigues-kimberlite-pipe--af6966e3-f1dd-4bfc-a867-6d4936df6fb5 Original source: https://money.tmx.com/en/quote/TRS/news/7566257181096312/tres-or-announces-type-ii-microdiamonds-dominate-at-the-guigues-kimberlite-pipe- Publisher: tmx Original announcement: 2021-04-06T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Tres-Or Resources Ltd. - Ticker: TRS - Exchange: TSX - Region: Quebec - Primary commodity: Diamonds - Secondary commodities: None reported - Document categories: Other, Drill results - Extracted: 2026-08-21 13:19:59 UTC Narrative sentiment: 0.90 · Bullish ## Minestarters Atlas summary Tres-Or Resources Ltd. announced that highly desirable Type II microdiamonds, lacking measurable nitrogen, dominate samples from the Guigues Kimberlite pipe in Quebec. Fourteen out of seventeen microdiamonds tested were identified as Type II, indicating significant potential for high-value gem diamonds. This positive development is advancing the project towards its first macro-diamond tests. Reasoning: The announcement highlights the discovery of a high proportion of Type II microdiamonds, which are rare and highly valued, significantly de-risking the project's potential for large, high-quality gem diamonds. This positive development, combined with strong indicator mineral chemistry, is advancing the project towards macro-diamond tests, despite a cautionary note that microdiamond results do not guarantee large stones. - Positive factor: dominance\_of\_type\_ii\_diamonds - Positive factor: potential\_for\_large\_high\_quality\_diamonds - Positive factor: strong\_diamond\_indicator\_mineral\_chemistry - Positive factor: excellent\_access\_and\_infrastructure - Positive factor: advancing\_to\_macro\_diamond\_tests - Negative factor: cautionary\_statement\_on\_large\_diamonds - Negative factor: more\_data\_required\_for\_grade\_confidence Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 19 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The announcement explicitly states that nitrogen measurements were conducted by the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services \(SRC\) using industry-standard micro-Fourier Transform Infrared Spectroscopy \(FTIR\). Evidence · text > 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 \(FTIR\). **Type II Diamond Dominance** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: 14 out of 17 microdiamonds tested were identified as Type II, which are rare and highly desirable. Evidence · text > 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. **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The technical disclosure was prepared under the supervision of Dr. Harrison O. Cookenboo, P.Geo., and Ms. Laura Lee Duffett, P.Geo., both Qualified Persons. Evidence · text > Disclosure of a scientific or technical nature related to the Company's projects and exploration activities in this news release was prepared under the supervision of Dr. Harrison O. Cookenboo, B.Sc., M.Sc., Ph.D., P.Geo., the Company's independent Qualified Person \(as such term is defined in National Instrument 43-101 \), and Ms. Laura Lee Duffett, P.Geo., the Company's President and CEO, who is a non-independent Qualified Person, both of whom have reviewed and approved the technical and scientific portions of this presentation. **Potential for Large Diamonds** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: Type II diamonds are highly desirable because many of the largest, highest quality gem diamonds ever recovered lack nitrogen. Evidence · text > 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 **Cautionary Statement** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The company notes that the recovery of Type II microdiamonds does not necessarily mean the kimberlite will host large Type II diamonds. Evidence · text > 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. ## Extracted facts Stored fact records: 0. Some facts used in scoring do not have a stored record. No stored fact records are available for this extraction. ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
