The report confirms the presence of lithium-bearing brines and provides a technical framework for future exploration, though it does not yet define a mineral resource. Reasoning: The filing of a maiden NI 43-101 technical report is a significant regulatory milestone that provides a formal framework for the project, though it confirms the project is still in the early exploration stage without a defined resource. - Positive factor: filing of maiden NI 43-101 technical report - Positive factor: confirms presence of lithium-bearing brines - Positive factor: established technical framework for exploration - Negative factor: no current mineral resource defined - Negative factor: project classified as early-stage exploration asset - Negative factor: data is historical in nature Facts used in scoring: 3 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release mentions that QA/QC procedures have been applied in accordance with industry standard practices. Evidence · text > Quality assurance and quality control \(“QA/QC”\) procedures have been applied **Infill Drilling** Polarity: neutral Story-specific tag Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The report describes historical drilling used to support exploration targeting rather than resource definition. Evidence · text > These results are historical in nature and support exploration targeting ## Extracted facts Stored fact records: 3. Some facts used in scoring do not have a stored record. ## Drill Results (3) ### PCT-18-01 [Link to this fact](https://atlas-staging.minestarters.com/news/vanguard-mining-corp-files-maiden-ni-43-101-technical-report-advancing-the-pocit--2def7fce-bc74-4472-bf99-b42838ae0f6b#fact-drill-facts-0) Pocitos I Historical result Needs review: historical\_restatement #### Identity - Hole ID: PCT-18-01 - Project: Pocitos I - Region: argentina - Reported Region: argentina - Ticker: UUU.CN #### Geometry - Hole Depth: 355 m #### Classification - Sample Type: drill #### QA/QC - QA/QC Disclosed: Yes - QP Signed: Yes - QA/QC Methods: standards #### Review - Needs Review: Yes - Review Reason: historical\_restatement - Interp.

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.
