The results include several high-grade gold intercepts over very narrow 0.762-meter sample lengths, with a peak assay of 11.3 g/t Au. These findings contribute to the understanding of the stratigraphy and will be used for an ancillary hydrogeological study. Reasoning: The announcement reports new gold assay results from a single drill hole, including a bonanza grade of 11.3 g/t Au. However, all reported intercepts are over very narrow 0.762 m sample lengths, and the drilling's primary purpose was hydrogeological advancement, which limits the immediate materiality for resource expansion. While a Qualified Person has reviewed the cores, detailed QA/QC methods for the reported assays are not provided. - Positive factor: high gold grades encountered - Positive factor: new drill results reported - Negative factor: very narrow intercept lengths - Negative factor: drilling primarily for hydrogeological study, not resource definition - Negative factor: low grade-thickness product for all intercepts - Negative factor: lack of detailed QA/QC methods for reported results Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 7 ## 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: Erik Ostensoe, P.Geo., a Qualified Person, has reviewed and approved the scientific and technical disclosure in this news release. Evidence · text > Erik Ostensoe, P.Geo., a geological consultant to the Company and a Qualified Person as defined by National Instrument 43-101, has reviewed the TAR24\_DH\_022 cores and approves the scientific and technical disclosure in this news release. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Sample 70 returned 11.3 g/t Au, which is well above the exceptional threshold for gold. Evidence · table > 11.3 Context: 2.48 **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 reported samples are all 76.2 cm in length, which is a very narrow apparent width, and no true width or orientation information is provided. Evidence · text > SAMPLE \(Size 76.2 cms\) **Exploration Drilling** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The drilling was conducted for 'hydrogeological advancement drilling' and to 'understand the porosity of the stratigraphy for the ancillary hydrogeological study', indicating an exploration-stage purpose. Evidence · text > The company’s intent was to accomplish double this depth from a higher collar near the top of the ridge. An innovative approach u sing RC tools to pass through the uppermost, most fractured and weathered strata \(anticipated to be about 8000 cms/80m\) and then to switch to full core drilling was intended. The drill hole, designated 24TAR\_RCDH\_021, did succeed in passing through the upper, broken, 8000 cms/80m but RC drilling efforts were defeated by the following 1000 cms/10m which in part comprised sand and broken rock that appears to have flowed in from nearby historic \(and unrecorded\) artisanal miners’ workings. These recordings and samples will supply a substantial amount of information to understand the porosity of the stratigraphy for the ancillary hydrogeological study. ## Extracted facts Stored fact records: 7.
