Full article: 2D electrical resistivity imaging of tantalite-bearing
The tantalite-bearing veins appear to be continuous in some profiles. Generally, the width of the tantalite-rich zones ranges from 3 m to about 32 m while the length varies from 40 m (Figure 3(d)) to 219 m (Figure 2(a)). In Figure 3(d), the main mineralised vein at the top right corner is 4.5 − 16 m thick and about 70 m long.
