Summary
Sunstone Metals Ltd is focused on updating the Mineral Resource at its Bramaderos Gold-Copper Project in southern Ecuador. The company is enhancing its existing 2.7 million ounces gold equivalent resource through a new 1,543-meter surface sampling program at the Brama-Alba porphyry. This initiative aims to upgrade geological interpretations and expand the mineralised area, especially in connection with the Melonal gold-copper porphyry. The completion of this sampling and mapping program is a strategic step towards a scoping study for the project, indicating robust economic potential in light of rising gold prices. Sunstone is also finding promising indications that the Copete and Porotillo porphyry systems may be contiguous, suggesting further resource growth potential.

  • Completion of a 1,543m surface sampling program at Brama-Alba.
