The results suggest an extension of zinc mineralisation at depth as the company works to upgrade the resource from Inferred to Indicated. Reasoning: High-grade pXRF readings extend the zinc-silver mineralisation at depth, though the lack of laboratory assay confirmation limits confidence. - Positive factor: extension of mineralisation at depth - Positive factor: record silver grades for the project - Positive factor: high-grade zinc spot readings - Negative factor: results are preliminary pXRF readings - Negative factor: laboratory assays still pending Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling extended mineralisation at depth. Evidence · text > resource-upgrade drilling extended mineralisation at depth **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 559 g/t silver is exceptionally high for a zinc project. Evidence · text > 559 grams per tonne silver, the latter a record for the project **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The results are explicitly stated as preliminary pXRF readings with laboratory assays still pending. Evidence · text > Rockfire stressed that the pXRF results are preliminary, with laboratory assays... still pending ## Extracted facts Stored fact records: 6.

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.
