Nine drill holes totaling 1,098 meters were completed, intersecting significant kimberlite intervals. Samples from both kimberlites will be sent for caustic fusion to determine diamond content, with results expected from mid-July to late August. Reasoning: The document reports successful exploration with the discovery of a new kimberlite \(Arbutus\) and significant kimberlite intercepts in delineation drilling at Sequoia. While no diamond grades are yet available, the extent of kimberlite intersected and the planned caustic fusion for diamonds are positive. The program also included an unsuccessful exploration hole. - Positive factor: Discovery of new kimberlite \(Arbutus\) - Positive factor: Delineation drilling on Sequoia kimberlite complex - Positive factor: Significant kimberlite intercepts in multiple holes - Positive factor: QA/QC procedures mentioned \(core splitting, experienced geologist, SRC lab\) - Positive factor: QP sign-off - Negative factor: No grades reported \(only kimberlite intercepts\) - Negative factor: True width not disclosed for angled holes - Negative factor: Unsuccessful exploration hole \(DG2022-04\) on a target Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drill program included exploration drilling for new kimberlite targets, leading to the discovery of the Arbutus kimberlite. Evidence · text > This work resulted in the discovery of the Arbutus kimberlite. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Six drill holes were directed towards the ongoing delineation of the Sequoia kimberlite complex, indicating infill drilling to better define the known body. Evidence · text > Six were directed towards the ongoing delineation of the Sequoia kimberlite complex **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document reports downhole intercept lengths for kimberlite without stating true widths, particularly for angled holes, which may overstate true thickness. Evidence · text > The intercepts in the angled holes suggest we are drilling of the southern edge of an eruption center. **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 release mentions core splitting, logging by an experienced kimberlite geologist for technical consistency, and samples being sent to SRC diamond laboratory. Evidence · text > the core is split with half or approximately 3.8kg per meter going to the lab for caustic fusion. ... logged by Dan Gainer, an experienced kimberlite geologist who logged the kimberlite discoveries last year which will provide technical consistency. ... Once logged and split the core will be sent to SRC diamond laboratory in Saskatoon. **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: Buddy Doyle, AUSIMM, a Geologist, is named as the Qualified Person for this news release under NI 43-101. Evidence · text > The Qualified Person for this news release is Buddy Doyle, AUSIMM, a Geologist with over 35 years of experience in diamond exploration, discovery, and evaluation. A Qualified Person under the provisions of the National Instrument 43-101. ## Extracted facts Stored fact records: 8.
