The hole returned a 31.8m interval at 1.07% Li2O, including a higher-grade 20.47m section at 1.33% Li2O, validating previous visual spodumene logging. Reasoning: First maiden assay results from the Whistlejacket project confirm the presence of a broad, consistent lithium-cesium-tantalum \(LCT\) mineralized body with grades exceeding previous visual estimates. - Positive factor: Maiden assay results confirm visual spodumene mineralization - Positive factor: Strong lithium-cesium-tantalum \(LCT\) pathfinder suite present - Positive factor: Consistent grades across a broad 31.8m zone - Positive factor: High-grade sub-interval of 1.33% Li2O - Positive factor: QA/QC protocols disclosed with certified lab and QP sign-off - Negative factor: True widths not yet determined Facts used in scoring: 5 ## 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: Release includes details on certified reference materials, blanks, and laboratory \(SGS\) procedures. Evidence · text > Certified reference materials and blanks were inserted into the sample stream as part of the Company's QA/QC procedures **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 explicitly states that true widths have not yet been determined. Evidence · text > All reported intervals are downhole lengths. True widths have not yet been determined. ## Extracted facts Stored fact records: 5. Some facts used in scoring do not have a stored record. ## Drill Results (5) ### WSTL0020 [Link to this fact](https://atlas-staging.minestarters.com/news/whistlejacket-lithium-project--b4fbf2d5-c8ab-4d59-86a4-cfb783bb453e#fact-drill-facts-0) Whistlejacket · lithium Historical result Needs review: historical\_restatement #### Identity - Hole ID: WSTL0020 - Project: Whistlejacket - Commodity: lithium - Region: usa\_az - Reported Region: usa\_az - Ticker: BHL #### Geometry - Grade: 1.07 - Grade Unit: % - Intercept: 31.8 m - From: 161.85 m - To: 193.65 m - Intercept Depth: 161.85 m #### Classification - Program: exploration - Sample Type: drill - Group ID: WSTL0020:161.85-193.65 - Mining Method: unknown #### Location - Loc.

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.
