Visual inspection of drill cuttings confirmed multiple wide intercepts of scheelite-bearing skarn, validating the geological model. Samples have been sent to an accredited laboratory for assay, with results expected in Q4 2026, which will inform a maiden Mineral Resource Estimate. The company highlighted prior metallurgical testwork confirming the project's amenability to standard processing. Reasoning: Great Western Mining announced the completion of its drilling campaign at the Defender Tungsten Project, with encouraging visual observations of scheelite-bearing skarn. While this is a positive step towards a maiden MRE, the lack of assay results means the full impact is yet to be determined. Prior metallurgical work indicates good processing amenability. - Positive factor: Drilling campaign successfully completed, meeting objectives. - Positive factor: Visual observations confirm scheelite-bearing skarn in multiple wide intervals, validating geological model. - Positive factor: Samples dispatched to an accredited laboratory for assay, with results expected soon. - Positive factor: Drilling will inform a maiden Mineral Resource Estimate. - Positive factor: Prior metallurgical testwork confirmed high tungsten recovery. - Negative factor: No assay results are reported in this announcement, limiting immediate quantitative assessment. - Negative factor: Drill sample recovery data has not been assessed to date, and potential biases need further work. Facts used in scoring: 4 ## Classification and evidence **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. Why it applies: The technical information in this release was reviewed and verified by Mr. Lewis Harvey and Mr. James Hogg, Principal Geologists for Addison Mining Services, who qualify as Competent Persons under JORC Code 2012 and Qualified Persons under AIM rules. Evidence · text > The technical information in this release which relates to GWMO 's Defender Tungsten Project is based upon and fairly represents information and data presented and reviewed by Mr. Lewis Harvey, MSc., Principal Geologist for Addison Mining Services, who is a Member of the Australian Institute of Geoscientists. The technical information has also been reviewed by Mr. James Hogg MSc, MAIG, Principal Geologist for Addison Mining Services \(AMS\). Mr Harvey and Mr Hogg have sufficient experience relevant to the style of mineralisation, the type of deposit under consideration and the activity undertaken to qualify as Competent Persons as defined in the JORC Code 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, and Qualified Persons under the AIM rules. **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 a detailed JORC Table 1 section outlining sampling techniques, sample preparation, quality of assay data, and quality control procedures including the insertion of CRMs, blanks, and duplicates. Evidence · text > GWM routinely insert, CRMS, blanks and duplicates into the sample stream. QC inserted at a rate of approximately 1:10. The quality and nature of assay data and laboratory tests are acceptable for the exploration work for this deposit. **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 fairly represents information and data reviewed by Competent Persons as defined in the JORC Code 2012 edition. Evidence · text > Mr Harvey and Mr Hogg have sufficient experience relevant to the style of mineralisation, the type of deposit under consideration and the activity undertaken to qualify as Competent Persons 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 Story-specific tag Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The reported skarn intervals are given as continuous lengths in feet and meters without stating true width or drill orientation relative to the mineralisation. 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 announcement explicitly states that assay results are pending and no exploration results are being reported herein, only visual observations. Evidence · text > Analysis is pending and no exploration results are being reported herein. ## Extracted facts Stored fact records: 1.

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.
