Sunstone Metals Ltd. announced more wide intersections, including some of more than 1g/t gold-equivalent, which will further underpin the upcoming initial Mineral Resource Estimate (MRE) at its Brama-Alba porphyry discovery in southern Ecuador. Sunstone is also pleased to announce the resumption of discovery drilling at three other porphyry targets within the Bramaderos concession and can report that drilling at two of those targets has returned visible copper mineralisation with the third not yet at target depth. All holes reported in this release for Brama-Alba intersected wide zones of gold-copper mineralisation.

The Bramaderos project is located immediately adjacent to the Pan American highway, and close to available hydroelectric power, supporting the economics of potential development opportunities. Ecuador sources 88% of its power from hydroelectricity and is ideally placed to participate in the global demand for clean energy sourced metals. The project is also supported by nearby commercial airports and significant cities (Loja, population 200,000) and has strong community support.

At El Palmar, drilling is in progress on target T2 and several additional drill targets have been defined. These will be tested over the coming months. Key points Strong assay results received from six drill holes at Alba and four holes from the eastern end of the Brama system; Alba and Brama form part of the Bramaderos Project Broad zones of gold-copper mineralisation have been intersected, including sub-zones of higher grade Significant results include: 49.45m at 0.60g/t AuEq* (0.37g/t gold and 0.13% copper), from 392m in BMDD035; 32m at 1.20g/t AuEq* (0.87g/t gold and 0.20% copper), from 386m in BMDD036; 115m at 0.66g/t AuEq* (0.41g/t gold and 0.15% copper), from 12m in BMDD039, including; 24.15m at 1.10g/t AuEq* (0.46g/t gold and 0.38% copper), from 31.35m and 69m at 0.61g/t AuEq* (0.36g/t gold and 0.14% copper), from 21m in BMDD043.

Drilling for the initial Mineral Resource Estimate has been completed but mineralization is open in several areas beyond the planned initial resource boundary. An Exploration Target will also be released in December to provide some guidance on opportunities to continue growing the scale of the Brama-Alba system. Exploration drilling has commenced at nearby porphyry targets Melonal, Sandia and Limon; The first hole has been completed at Melonal; Logging of the Sandia and Melonal holes indicate that they are altered and mineralised consistent with Brama porphyry type systems.
