GUAYABALES PROJECT
The Guayabales and San Antonio projects are located within the Marmato district of the prolific Mid-Cauca Belt of western-central Colombia. The Mid-Cauca Belt is one of the most underexplored mineral belts globally with a rich history of artisanal gold mining from Pre-Colombian and Colonial periods.
Most recent modern exploration, that only commenced in the early 2000´s, has proven numerous large porphyry gold and copper-gold discoveries (La Colosa – 28.5 MOz Au; Nuevo Chaquiro – 4.7 Mt of Copper metal, 7.1 Moz Gold, 93 Moz Silver and 85 Kt Molybendum metal for over 30 million gold equivalent ounces) and porphyry-related gold-silver vein systems (Buritica +11 MOz Au, Marmato +6 MOz Au).
Individual deposits are hosted in the Romeral-Cauca structural corridor; a tectonized basement complex containing Paleozoic sediments and Mesozoic oceanic rocks that are overlain by Oligocene siliciclastic and Miocene arc-volcanic rocks. Metal mineralization ages range from 9 to 5.6 million years and are directly related to the injection of Miocene intrusive suites into the basement complex.
