Sunstone Metals Hits Wide Gold-Copper Zones at Porotillo, Enhancing Resource Prospects
June 1, 2026, 9:18 PM EDT. Sunstone Metals (ASX: STM) reported significant gold-copper mineralisation at its Porotillo prospect within the Bramaderos project, with drill holes intersecting 200m and 151m of mineralisation from surface. Highlights include 19m at 1.01 g/t gold equivalent (Au-Eq) and 26m at 0.84 g/t Au-Eq. These results extend known zones by 380m, bolstering plans to upgrade the Copete-Porotillo exploration target into JORC Mineral Resources by H2 2026. The ongoing drilling program aims to convert lower-confidence inferred resources into indicated resources, critical for future development studies. Sunstone is also expanding trenching to improve geological definition. The exploration target estimates 1.7-3.5 million ounces of gold equivalent over 135-180 million tonnes. This progress follows a prior retraction of production forecasts due to resource classification uncertainties, highlighting the company's focus on building a robust resource base.
