Spodumene pegmatites within the Ewoyaa project license area, which are hosted by Birimian mica schists and associated granitoids. The schists are locally tourmalinized and may contain small (2–3 cm) pods rich in tourmaline, garnet, and Fe oxides. The metasedimentary rocks have a NE-trending foliation with a moderate to steep dip to the southeast. Pegmatites vary between 2 and 60 m in width and in some cases can be traced for up to 800 m along strike.
