The Project lies within the Neoproterozoic Xixano Complex, which in the Balama region comprises a NNE-trending synform with a core of mafic orthogneisses surrounded by micaceous gneiss and schist, quartz-feldspar gneiss, quartzite and marble. Graphitic gneiss and schist, locally enriched in vanadium within the micaceous gneiss unit, dominates the Balama area.
Higher grade graphite mineralisation is hosted by graphitic schists interlayered with lower grade psammites and intruded by volumetrically minor pegmatites. At Balama East, the graphitic units bifurcate around a granitic intrusion which outcrops as a dominant hill. The graphitic units dip variably to local grid north at an average of around 45°.
Relative to the pre-mining surface, the graphitic schists were overlain by an average of around 2 to 3 m of un-mineralised soil and overburden, and variably weathered to an average depth of around 30 m.
The graphite mineralisation is mostly contained in stratiform graphitic schists. The flake size of the graphite is up to 4mm.
The mineralisation interpretation extends over a strike length of 1,050 m and 1,450m at Balama West and Balama East, respectively. The mineralisation is open to the west, east and north.
Mepiche (formerly Balama East) mineralised domains comprise a main zone of generally moderate TGC grades flanked to the south by a comparatively narrow zone of lower TGC grades. In the east, the domains bifurcate ar ........
