Mineralization is typically observed as breccia matrix replacement and is generally dominated by chalcopyrite and sometimes by bornite with chalcocite – particularly in the higher-grade zones. Mineralization can also be observed as vein and replacement zones containing chalcopyrite and calcite/dolomite gangue. These styles of mineralization were observed in all holes mentioned in this press release.
