Sunstone Metals Limited is an ASX-listed mineral exploration company primarily engaged in the exploration and evaluation of high-quality gold and copper properties. The company holds significant interests in two world-class porphyry projects in Ecuador: the Bramaderos Gold-Copper Project and the El Palmar Copper-Gold Project. The Bramaderos Project, located in southern Ecuador, features both at-surface and deeper porphyry gold-copper systems with an initial mineral resource estimate of 156 million tonnes at 0.53 g/t AuEq, equating to 2.7 million ounces gold equivalent, and exploration targets indicating significant additional potential resources. The El Palmar Project, situated in northern Ecuador, offers a large-scale porphyry exploration target with an estimated resource range between 15 to 45 million ounces AuEq within a vast tonnage range of 1.0 to 1.2 billion tonnes.
