Summary
Sunstone Metals Ltd, an ASX-listed mineral exploration company, has announced the commencement of a significant drilling campaign at their Bramaderos Gold-Copper Project in Southern Ecuador. The goal is to expand the existing 3.6 million ounces of gold equivalent (Moz AuEq) resource. This operation targets the Copete-Porotillo porphyry complex, with an exploration target of 135-180 million tonnes at 0.25-0.40 g/t AuEq, potentially adding 1.7 to 3.5 Moz AuEq. The drilling initiative follows promising trenching results at Porotillo, including a 78-meter intersection with 0.57 g/t AuEq. Two diamond drilling rigs are being utilized, with the aim to provide substantial resource growth and shareholder value. A scoping study, including metallurgical testing, is currently underway to assess the economic potential of the Bramaderos and associated porphyry systems.
