Oribella

Overview

The Oribella project comprises 20,000 ha and is located in Antioquia Department within the Middle Cauca Belt metallogenic province, which has a remarkably high distribution of large Au-Cu Porphyries, commonly showing related epithermal elements, and also epithermal replacement and vein systems without direct relationship to intrusives. It is within a metal rich part of the Middle Cauca Belt metallogenic province that extends for 120 km and hosts Buritica and Nuevo Chaquiro (Quebradona).

Outcrop recently expanded the Oribella Project with new applications and is currently looking for a joint venture partner.

The area is accessible from Medellín by paved roads to Concordia (National Route 60 and Secondary Departmental Bolombolo-Concordia Route). 

Geology

The Oribella Gold Project lithology includes oceanic domains of deep-water pelagic and turbidite-laminated sediments, and submarine tuffs tectonically juxtaposed against basaltic volcanic rocks. At Oribella, the pelagic sediments occur to the west, transition rocks center, and volcanic domains to east.

Mineralization shows both structural and lithologic controls, including local, fracture-controlled and pervasive silica replacement.

Mapping outcropping near surface gold mineralization, and tabular dikes and breccias suggest generally blind Cu-Au porphyry mineralization. Additional stream sediment sampling and prospecting is required to determine the extent of the gold-copper system. The current target as defined by rocks, limited trenching and especially soils is of significant size (500 m) and open to the north and south.

Exploration

Outcrop was attracted to the area by reports provided by Antioquia Gold and Soratama (Barrick Gold) indicating possible high sulfidation mineralization. 

Exploration completed by Outcrop includes mapping, channel sampling, hand trenching, and soil sampling. Outcrop soil sampling shows robust gold and copper anomalies that are spatially offset to each other and also an inferred epithermal zonation pattern in trace elements in relation to gold. The gold anomaly is approximately 500 m by 250 m and open in two directions. Limited hand trenching within the soil anomaly shows 11 m @ 1.1 g Au/t in the subsurface.

Future Plans

Outcrop plans to start social work in at Betullia to advance the project towards a public audience that will allow the company to title key applications in the short term. Outcrop is actively seeking a funding exploration partner.
