Geological logging and UV inspection visually confirmed scheelite-bearing skarn over wide intervals at three target areas, validating the geological model. While quantitative assay results are pending and expected in Q4 2026, these visual observations will inform a maiden Mineral Resource Estimate. Reasoning: The company completed its first RC drilling campaign at the Defender Tungsten Project, visually confirming scheelite-bearing skarn over wide intervals, which validates the geological model and will inform a maiden MRE, but quantitative assay results are pending. - Positive factor: Completion of first drilling campaign - Positive factor: Visual confirmation of scheelite-bearing skarn over wide intervals - Positive factor: Validation of geological model - Positive factor: Supports future maiden Mineral Resource Estimate - Positive factor: QP/CP sign-off and JORC compliance - Negative factor: No quantitative assay results reported yet - Negative factor: Visual observations are not quantitative grades Low confidence — this extraction should be reviewed alongside the original source.

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.
