The drilling focused on expanding the D Vein, with significant silver, lead, and zinc intercepts, and some gold. Highlights include 1,580 gpt silver over 0.30 meters in CDH-26-242 and 816 gpt silver over 0.40 meters in CDH-26-251. The program aims to expand the existing inferred mineral resource and has identified new blind vein targets. Reasoning: The drill results show high-grade silver intercepts and successful expansion of the D Vein system, with good QA/QC. The program is advancing well and identifying new targets, which is positive for the project's future. While some intercepts are narrow, the overall grades and continuity are encouraging. - Positive factor: High-grade silver intercepts, some exceeding 500 gpt, indicating bonanza grades. - Positive factor: Expansion of known mineralization along strike and to depth, extending the D Vein. - Positive factor: Identification of new blind vein targets, suggesting further exploration potential. - Positive factor: Detailed QA/QC disclosure and QP sign-off enhance credibility of results. - Positive factor: True width estimates provided for intercepts. - Negative factor: Some intercepts are narrow, despite high grades. - Negative factor: Gold mineralization is noted as irregular, suggesting it's not a consistent primary target. 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.
