The two dominant vein systems within the Miranda Alto concession are the Azul Vein and the Miranda Vein. The Azul Vein is exposed on surface directly east of the Miranda Vein, near the eastern boundary of the concession. Underground work has revealed that there are at least two other subsidiary veins (Sul, Estrella) that lie parallel to the Miranda Vein. The Viscaya Vein lies directly west of the Miranda Alto concession. There are additional unexplored subsidiary veins between the Viscaya and Miranda veins. The mineralization in the concession area ranges from a gold:silver ratio of 1:10 to 1:100, all within a small area examined and sampled. The major veins (Azul, Viscaya) are recognized from the Rio Amarillo north for at least 4 kilometres, to the Miranda Alto concession.
Historic Resource Estimations
