The drilling successfully extended the main pegmatite body by 800 meters to the east and 400 meters to the south, significantly increasing the overall footprint. The program also identified three new spodumene-bearing pegmatitic bodies and returned high-grade lithium and tantalum assays from several holes, confirming the continuity of mineralization. Reasoning: The preliminary drill results indicate a significant expansion of the known mineralized footprint and the discovery of new high-grade lithium-tantalum zones, confirming continuity and adding substantial potential to the project. While QA/QC procedures are mentioned, explicit lab certification and cut-off grades are not provided. - Positive factor: Significant extension of mineralized footprint - Positive factor: Discovery of new spodumene-bearing bodies - Positive factor: High-grade lithium intercepts - Positive factor: Good tantalum byproduct grades - Positive factor: Continuity of mineralization confirmed - Positive factor: True width range disclosed - Positive factor: QA/QC procedures disclosed - Negative factor: Only preliminary results, not all assays received - Negative factor: Lab certification not explicitly stated - Negative factor: Cut-off grade for compositing not disclosed Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 14 ## 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 release explicitly states that quality assurance and quality control procedures have been implemented, including the regular insertion of standards, duplicates, and blanks. Evidence · text > Quality assurance and quality control procedures have been implemented to ensure best practices in sampling and analysis of the drill core samples. Standards, duplicate and blanks were regularly inserted into the sample stream. **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The document provides a range for the true thickness relative to the core length. Evidence · text > \* Core length; the true thickness is between 80 to 95% of the core length. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Recent drilling has extended the main pegmatite body significantly towards the east and south, expanding the overall footprint. Evidence · text > extending the main pegmatite body by about 800 meters towards the east and by about 400 meters to the south, thus bringing its overall footprint to 1250 m x 800 m. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: One of the stated goals of the drill program is to expand laterally all around the existing mineralized footprint, which includes infill drilling. Evidence · text > Expand laterally all around the existing mineralized footprint \(RW-26-29 to 34, RW-26-45 & 46\) **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: The release does not state the cut-off grade used for reporting the high-grade intervals. Evidence · text > Assay results were received for holes RW-26-29, RW-26-30 and RW-26-45 , and returned lithium and tantalum assays, as highlighted: **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: While a laboratory is named, the document does not explicitly state that the lab is certified or accredited. Evidence · text > The drill core samples were delivered, in secure tagged bags to the ALS Minerals laboratory facility in Val-d'Or, Québec. ## Extracted facts Stored fact records: 14.

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.
