LAS VEGAS, June 4, 2013 /PRNewswire/ - Orofino Gold Corp. (PINK OTC: ORFG) ("Orofino Gold" or the "Company") is pleased to announce that in Colombian mining districts of Cerro San Carlos and Santa Cruz areas in the Dept. of Bolívar (Central Cordillera), and the Vetas-California-Angostura region of the Dept. of Santander (Eastern Cordillera) mineralization appears to be Mid- to Late-Jurassic, hosted within intrusive and/or volcanic rocks of similar age.
Mineralization and alteration, dominated by symmetrical silicification, argillitisation-sericitisation, and pyritic sulphidation +/- propylitisation is intensely developed, and observed on a km-scale basis. Gold-silver mineralisation is hosted within dense networks of structurally-controlled cm to 10´s-of-cm scale veinlets and sheeted veins, and phreatic breccia zones. Vein-fillings are dominated by +50% pyrite, with lesser quartz and minor base metal sulphides. In the case of Cerro San Carlos mineralization is volcanic-hosted, and underlain by a plutonic root zone where chalcopyrite becomes the dominant vein let sulphide, gold grades diminish somewhat, and alteration approaches phyllic in character. Thus, metal and alteration zones at San Carlos suggest porphyry potential below the volcanic cover. Orofino Gold has samples from these structurally controlled vein systems that will be assayed to further provide empirical metallurgical data for the design of the new improved gold recovery system currently under development by the joint venture recovery design team. The historical samples to date have run 30 + gm/ Gold and 60 + gm/Silver and recoveries will be improved greatly with the new system. Multi-nationals such as Anglo-America Ashanti and AUX Minerals controlled by Billionaire Ike Batista have discovered multi billion dollar, multi million ounce gold ore bodies in the prolific Cordillera systems of Colombia.
