The re-assays, which include intercepts up to 2,992 g/t Ag and 4.1 g/t Au, are being incorporated into a planned maiden JORC Mineral Resource Estimate for Q4 2026. This work aims to validate and upgrade the existing foreign mineral resource, adding previously unconsidered gold potential. Reasoning: The re-analysis of historical drill core at Shafter has significantly increased silver grades and identified previously unquantified high-grade gold mineralization, enhancing the project's multi-commodity potential. This work, conducted with modern QA/QC, is a crucial step towards a maiden JORC-compliant resource estimate, de-risking the project and adding value. - Positive factor: significant\_grade\_uplift\_in\_silver - Positive factor: identification\_of\_high\_grade\_gold\_mineralisation - Positive factor: rigorous\_qaqc\_protocols\_for\_reanalysis - Positive factor: true\_width\_disclosed\_for\_key\_intercepts - Positive factor: progress\_towards\_maiden\_jorc\_resource - Negative factor: reanalysis\_of\_historical\_data\_limits\_novelty - Negative factor: historical\_resource\_estimate\_is\_not\_jorc\_compliant - Negative factor: cut\_off\_grades\_for\_historical\_results\_not\_explicitly\_stated 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.
