## Minestarters Atlas summary

Arizona Gold &amp; Silver reported successful metallurgical test results from a bulk sample at the Philadelphia gold-silver project. Gold recoveries reached up to 99% via agitation leach and 84% via heap leach using HPGR crushing, demonstrating strong potential for both high-grade and lower-grade ore processing.

Reasoning: The results show high gold recoveries across two different processing routes \(agitation and heap leach\) on a bulk sample, with HPGR technology providing a clear metallurgical advantage.

- Positive factor: High gold recovery in agitation leach \(up to 99%\)

- Positive factor: Strong heap leach recovery \(84%\)

- Positive factor: HPGR crushing demonstrated significant improvement over conventional crushing

- Positive factor: Low cyanide and lime consumption in agitation tests

- Positive factor: QA/QC disclosed with QP sign-off

- Negative factor: Silver recovery in heap leach is relatively low \(37%\)

Facts used in scoring: 4
