Anza / 10-11m oz Buritica17 Dec 2020 10:30
The explorations drillholes in Charrascala in 2018 intercepted gold anomalies along a structural corridor of 800 m from north to south. These minerals interceptions have high grade intervals that vary between 0,9 m to 3,8 m and have veins zones of high contents of sulphide, mainly pyrite, with minor pyrrhotite, chalcopyrite and sphalerite. The hydrothermal alteration has a strong silicification and propylitisation that trends to show the presence of structures, which control the mineralization. The country rocks are intermediate to the mafic volcanic flows, tuff and 3 breccia of the Barroso Formation. The Barroso Formation is part of the Igneous–sedimentary sequence that has many of the most important minerals deposits of the Oro del Cauca Belt, including the Burítica deposit.
