The company plans to use these results to define a potential resource expansion and extend the mine life, with an expanded drill program and an additional rig. The reported gold equivalent grades are comparable to those in the current mine plan, which are considered economically viable due to a low strip ratio. Reasoning: Heliostar's drill results from the San Agustin Mine indicate a significant extension of oxide gold mineralization beyond the current reserve, with grades comparable to the existing mine plan. The program has been expanded, and the results are intended to support a resource update and mine life extension. While true widths are unknown and cut-off grades are not disclosed, the company has robust QA/QC procedures in place, and the extension of economically viable mineralization represents a positive development for the project. - Positive factor: Step-Out Extension - Positive factor: Resource Expansion Potential - Positive factor: Increased Drill Program - Positive factor: QP/CP Signed - Positive factor: Certified Lab - Negative factor: Apparent Width Only - Negative factor: Cut-off Undisclosed Facts used in scoring: 108 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 108.

Evidence · table > 47.0 Context: and ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
