Mazowe Mine is situated in the west-central part of the Harare greenstone belt. Orebodies here generally comprise shear zones which are in-filled with gold-bearing sulphides and quartz. The mineralised zones are up to 1.0 metre in width, range from 25 to 200 meters, have average grades of 4 to 5g/t, and generally dip between 10̊ and 60̊ to the north.
Gold mineralisation is associated with the sulphide species pyrite, pyrrhotite and arsenopyrite. In most cases, gold is strongly associated with this sulphide mineralisation and only to a limited degree with quartz veins. Approximately 70% of the gold present occurs as ‘free gold’, and over 15 mineralised structures have been exploited to date.
Mazowe Mine is one of the oldest mines in Zimbabwe and exploration and development in this region dates back to 1890. The mine covers 1,955.5 hectares of land.
