Mineralisation
 
At Cerro del Gallo higher grade gold mineralisation is found within a wallrock “annulus” proximal to the felsic intrusion. On the western side of Cerro del Gallo the gold-rich zone appears to be controlled in part by a specific stratigraphic unit 60-80m thick above, and partly overlapping a contact with a shallow dipping shoulder of the felsic intrusion. On the eastern side of Cerro del Gallo the gold-rich zone is 20-30m wide and closely associated with the sub-vertical wallrockfelsic intrusion contact. Peripheral to the gold zone, the copper grade of the mineralisation appears to increase while the gold grade decreases.
