Nai-Nais
- Historical production of Sn and Ta
- Previously sold conc. to ISCOR – compatibility with processing facility similar metallurgy
- Swarm of pegmatite intrusions closely spaced
- Near Uis processing plant-36km
- Pegmatites extend from surface
- Historically opencast mining
- Low stripping ratio
- Water-supply infrastructure 2 km south west
- Li-bearing minerals include spodumene, petalite and lepidolite
- Grab sample results:
- ~3,92% Li₂O
- ~ 0,246% Sn
- ~60 ppm Ta
- Future programmes::
- Map mineralisation horizons
- Characterise pegmatite size, mineralogy and geology
- Establish bulk Li-Sn-Ta grades
