The program, comprising 23 holes totaling 2,590 meters, visually confirmed multiple broad intervals of scheelite-bearing skarn, validating the company's geological model. Assay results are pending and will be used to inform a maiden Mineral Resource Estimate. Reasoning: The completion of the first drilling campaign at the Defender Tungsten Project is a positive step, with visual observations confirming broad zones of scheelite-bearing skarn. However, the absence of assay results means the economic significance of these intercepts cannot yet be determined, leading to moderate materiality and confidence. - Positive factor: Visual confirmation of scheelite-bearing skarn across multiple broad intervals validates the geological model. - Positive factor: The drilling campaign is the first for the project and is intended to inform a maiden Mineral Resource Estimate. - Positive factor: Comprehensive QA/QC procedures are disclosed, including the use of an accredited laboratory and sign-off by Competent Persons under JORC 2012. - Negative factor: No assay results are reported in this announcement, limiting the quantitative assessment of mineralization. - Negative factor: Drill sample recovery data has not been fully assessed, and potential biases due to preferential loss/gain of material have not been checked. - Negative factor: The reported intervals are apparent widths only, with no true width stated. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 3 ## 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 includes extensive QA/QC disclosure in a JORC table, mentioning an accredited laboratory, Competent Person sign-off, and methods like standards, blanks, and duplicates. Evidence · table > AAL is an accredited laboratory. Standard four acid digest and multi-element ICP analysis. Context: Sampling techniques **JORC Compliant** Polarity: positive Story-specific tag Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The technical information is based on and verified by Competent Persons as defined in the JORC Code 2012 edition. Evidence · text > qualify as a Competent Person as defined in the JORC Code 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. **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 intervals are given as downhole lengths \(e.g., '100 ft \(31 m\) of continuous skarn'\) with no true width or drill orientation provided for these specific visual intercepts. Evidence · text > Drilling intersected 100 ft \(31 m\) of continuous skarn from 50 ft \(15 m\) to 150 ft \(46 m\) depth **No Assay Results** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document explicitly states that 'Analysis is pending and no exploration results are being reported herein,' indicating that only visual observations are available, not quantitative grade data. Evidence · text > Analysis is pending and no exploration results are being reported herein. **Maiden Resource** Polarity: neutral Story-specific tag Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The drilling results are intended to 'inform a maiden Mineral Resource Estimate', indicating this is the first formal MRE for the project. Evidence · text > inform a maiden Mineral Resource Estimate \("MRE"\). ## Extracted facts Stored fact records: 3.
