Sunstone Metals Ltd (ASX:STM) managing director Patrick Duffy joins Proactive’s Tylah Tully to discuss the maiden mineral resource estimate (MRE) for the El Palmar gold-copper porphyry project in northern Ecuador. The initial estimate from the T1 deposit records 1.2 million ounces of gold equivalent (AuEq), establishing a solid foundation for future exploration. The resource is at surface level and suitable for open-pit mining. T1 deposit contains 64 million tonnes of ore with a grade of 0.60 g/t AuEq, including 0.41 g/t gold, 0.13% copper and 0.7 g/t silver. The MRE was derived from 17,699 metres of drilling. Sunstone Metals has also set an exploration target of 1.0 to 1.2 billion tonnes with the potential for 10 to 27 million ounces of gold and 1 to 3.7 million tonnes of copper. Duffy emphasised the potential for El Palmar to join the ranks of Tier-1 deposits, with similarities to Solgold's Cascabel Alpala and Codelco's Llurimagua deposits in the same region. Early-stage testing shows favourable recovery rates, with gold recovery at 90% and copper at 78%. Ongoing drilling and discussions with strategic partners aim to unlock further value from the project. #ProactiveInvestors #SunstoneMetals #ASX #ElPalmar #GoldCopper #PorphyryProject #MiningExploration #MineralResource #Tier1Discovery #EcuadorMining #OpenPitMining #ExplorationTarget #MetallurgicalTesting #GoldPrices #CopperMining #StrategicPartners #ResourceExpansion #MRE #GoldCopperDiscovery #MiningPotential #PorphyryDeposit #MineralExploration
