The mineralization is disseminated and hosted in volcanic and sedimentary rocks (breccias and tuffs). The deposit is exposed at surface and is currently defined over a strike length of 1,600 metres oriented in a northwest/southeast direction and a width of 750 metres. The mineralization is generally flat-lying and extends up to 300 metres in depth. The resource remains open to the south and southeast (Oct/02).
The mineralization is disseminated and is hosted in volcanic and sedimentary breccias and tuffs. The deposit is of the high sulfidation type and is similar in style to the mineralization at Pierina mine.
Most of the Lagunas Norte mineralization is contained in oxide breccias with about 15% occurring in sulphide breccias. The mineralization occurs at surface, is generally flat-lying and extends up to 300 metres depth in some areas. The mineralization is controlled by lithology as well as structure (Oct/02).
The Lagunas Norte project is being built as an open pit mine and heap leaching operation, using equipment, facilities and processes which have been proven in similar commercial applications throughout the world, including at Barrickâ€™s Pierina mine.
