Iron ore canga mapping with UltraGPR, Simandou, Guinea, 2009
Deposits of iron ore are often low conductivity levels ranging from 0.12 to 1 mS/m, and are generally well drained, making them ideal candidates for evaluation with UltraGPR resources.
Although the bands of iron formation deposits are often hundreds of metres deep, UltraGPR systems allow differentiation between high-resolution areas and areas not friable in the first 80 metres, while these changes are not easily detectable by grid drilling.
Deposits can also offer an excellent environment for UltraGPR systems, which can be up to 100 metres deep.
