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.
