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.
