The campaign follows recent high-grade silver-equivalent intercepts and aims to expand on the existing exploration target. Drilling is expected to begin after a shareholder meeting on 28 October, pending approval of a recent £1 million placement. Reasoning: The company is announcing a new drilling campaign to test depth extensions of a known discovery, following a recent capital raise. - Positive factor: Planned deeper drilling to test for higher-grade sulphide system - Positive factor: Recent high-grade silver equivalent intercepts reported - Positive factor: Upcoming maiden mineral resource estimate expected by end of 2026 - Negative factor: Drilling commencement is subject to shareholder approval of recent placement Facts used in scoring: 2 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The company is planning to drill deeper to test the extent of the existing discovery.

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.
