## Minestarters Atlas summary

Arizona Sonoran has completed its Pre-Feasibility Study \(PFS\) drilling program at the Cactus Project, reporting consistent copper porphyry mineralization and significant step-out extensions at Cactus West. The company is now initiating a Definitive Feasibility Study \(DFS\) infill drilling program to upgrade resources to the Measured category.

Reasoning: Successful completion of PFS drilling with high-grade intercepts and significant step-out extensions, supporting upcoming MRE update and DFS infill program.

- Positive factor: consistent copper porphyry mineralization

- Positive factor: step-out drilling extended mineralized zones

- Positive factor: high mineral resource estimate conversion rate expected

- Positive factor: QA/QC disclosed

- Negative factor: true widths not known

## 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.
