Drilling expands Melonal porphyry system

Key points

• Drill holes MEDD004 and MEDD006 at Melonal returned long intervals of gold and copper mineralisation
• MEDD004: 296.7m grading 0.43 g/t AuEq from surface, including 64.3m at 0.69 g/t AuEq
• MEDD006: 102m grading 0.52 g/t AuEq from surface, including 48.5m at 0.62 g/t AuEq
• Trench PO-8 at Porotillo returned 109.7m grading 0.61 g/t AuEq

Full summary

Sunstone Metals Ltd. has announced the successful expansion of the Melonal porphyry system with two new drill holes, MEDD004 and MEDD006, returning long intervals of gold and copper mineralisation. MEDD004 returned 296.7m grading 0.43 g/t AuEq from surface, including 64.3m at 0.69 g/t AuEq. MEDD006 returned 102m grading 0.52 g/t AuEq from surface, including 48.5m at 0.62 g/t AuEq. Additionally, trenching at Porotillo has continued to expand the known mineralisation with Trench PO-8 returning 109.7m grading 0.61 g/t AuEq. These results support Sunstone's view that there is significant potential to grow the existing resource base at the Bramaderos Project in Ecuador.
