[{"type":"text","content":"Hannan Radiometric Dating Confirms Miocene Porphyry Belt at the Previsto Copper-Gold Project, PeruVANCOUVER, BC / ACCESSWIRE / November 4, 2021 / Hannan Metals Limited (\"Hannan\" or the \"Company\") (TSXV:HAN)(OTC PINK:HANNF) is pleased to report that U-Pb zircon dating on four porphyry intrusive centres within an area of 140 by 50 kilometres has defined a previously unrecognized Miocene metallogenic belt associated with significant BLEG, float and outcrop Cu-Au geochemical anomalism at its 100%-owned Previsto project in Peru. Highlights:Radiometric dating work by Hannan has identified a previously unrecognized Miocene copper-gold metallogenic belt in the sub-Andean zone of central Peru, with eight porphyry samples within an area of 140 by 50 kilometres yielding ages ranging from 21.5 Ma to 12.2 million years (\"Ma\"; early to mid-Miocene).This new district overlaps in age with the Miocene magmatic arc in the Western Cordillera of Peru, where some of Peru's largest porphyry copper+/-gold and epithermal gold deposits were formed at the same time. This work ‘re-draws' the map of where such deposits can be found and verifies Hannan's assumptions that Previsto represents a new search space in a country thought to be mature in its exploration potential. (Figure 2).Hannan has continued to stake additional ground and increased its land position by 7% for a total of 113,200 ha (1,132 sq km). Fourteen mining concessions for 13,500 ha (135 sq km) are now granted (Figure 3).The Company is currently working with local stakeholders to plan next steps.Michael Hudson, CEO, states \"Through boots on the ground exploration and modern scientific methods, Hannan has defined a greenfield porphyry copper exploration district in non-traditional areas of the Peruvian sub-Andean region. All dates are interpreted to represent the timing of emplacement of the porphyry intrusions and associated mineralization. The presence of Miocene magmatic rocks in the sub-Andean zone of Previsto is considered regionally unusual and a potentially significant finding for future discovery. The case for \"young\" porphyry deposits located in a back-arc setting, that is to say, far inboard of their volcanic arc contemporaries is best exemplified by the case of Bajo de la Alumbrera (pre-mining measured resource 695 Mt @ 0.51% Cu, 0.66 g/t Au) in Argentina, which lie...
