Indicated and measured mineral resources totaling 22.5 Mt grading 10.0 g/t Au and 67.5 g/t Ag; Proven and probable reserves 14.4 Mt at 8.3 g/t Au and 63.8 g/t Ag). Mineralization is hosted within quartz-carbonate veins, hydrothermal breccias, and vein stockworks that cut the Hazelton Group. Pyrite crystallized during multiple hydrothermal stages before, during, and after the main stage of gold and silver mineralization.
