The program of 33 holes targeted the Freeman veining, yielding high-grade gold and antimony intercepts over narrow true widths, including 57.6 g/t gold and 25.4% antimony over 0.17m true width in TB055. The drilling has increased geological confidence and identified further exploration targets along strike and at depth. Reasoning: The infill and extension drilling at the True Blue deposit delivered several high-grade gold-antimony intercepts, significantly increasing geological confidence in the Freeman vein and identifying new targets along strike and at depth. The results include bonanza grades over narrow true widths, typical for this epithermal deposit type, and are supported by robust QA/QC. - Positive factor: Bonanza Intercept - Positive factor: True Width Disclosed - Positive factor: QA/QC Disclosed - Positive factor: Step-Out Extension - Positive factor: Infill Drilling - Negative factor: Apparent Width Only - Negative factor: Cut-off Undisclosed 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.
