Chalcopyrite-pyrite-pyrrhotite mineralisation was found immediately below
420m of cover – replacements, vein and breccia infill.

Up to 14.7 g/t Au was found associated with pyrrhotite-quartz-
carbonate and associated actinolite-biotite – observed metal
association +1 g/t Au, +0.1 % Cu and +100’s ppm Bi 1
