The program, comprising 23 holes totaling 2,590 meters, visually confirmed multiple wide intervals of scheelite-bearing skarn mineralization. Samples have been sent to an accredited laboratory for assay, with results expected in Q4 2026, which will be used to inform a maiden Mineral Resource Estimate. Reasoning: The announcement reports the completion of a drilling campaign at the Defender Tungsten Project, with positive visual observations of scheelite mineralization. While no assay results are yet available, the completion of drilling and the visual confirmation of mineralization are positive steps towards a maiden MRE. The detailed JORC Table 1 disclosure provides transparency on the drilling and sampling procedures, although some QA/QC aspects are still pending. - Positive factor: Drilling campaign completed on schedule - Positive factor: Visual observations confirm scheelite-bearing skarn in multiple wide intervals - Positive factor: Results will inform a maiden MRE - Positive factor: JORC 2012 compliant QA/QC procedures are in place - Negative factor: No assay results reported, only visual observations - Negative factor: Recovery data not assessed to date, potential for bias not checked - Negative factor: Database validation and verification pending Facts used in scoring: 4 ## 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 includes extensive JORC Table 1 disclosure detailing QA/QC procedures, including the use of CRMs, blanks, and duplicates, and analysis by an accredited laboratory. Evidence · table > GWM routinely insert, CRMS, blanks and duplicates into the sample stream. QC inserted at a rate of approximately 1:10. Context: Nature of quality control procedures adopted \(e.g. standards, blanks, duplicates, external laboratory checks\) and whether acceptable levels of accuracy \(i.e. lack of bias\) and precision have been established. **No QA/QC Disclosure** Polarity: negative Story-specific tag 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: The document states that 'Recovery data has not been assessed to date' and 'No recovery data is available for comparison and scattergram analysis at this time. Further work is required to check against potential biases.' Evidence · table > No recovery data is available for comparison and scattergram analysis at this time. Further work is required to check against potential biases. Context: Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Status: scored - Historical: No #### Dates - Event date: 2026-09-23T00:00:00.000Z Reasoning: A wide visual intercept of the target mineralization is a positive sign for exploration, indicating the presence of the mineralized system. However, the lack of assay results and true width limits the confidence and materiality. - Positive factor: Wide interval of continuous skarn - Positive factor: Visible scheelite observed throughout - Negative factor: Only visual observation, no quantitative grade - Negative factor: Apparent width only, no true width stated Evidence · text > Drilling intersected 100 ft \(31 m\) of continuous skarn from 50 ft \(15 m\) to 150 ft \(46 m\) depth, with visible scheelite identified throughout the interval. #### Tags used in scoring **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).
