Deposits of iron ore are often low conductivity levels ranging from 0.12 to 1 mS / m, and are generally well drained, making it ideal candidates for evaluation UltraGPR resources. Although the bands of iron formation deposits are often hundreds of meters deep, UltraGPR systems allow differentiation between high-resolution areas and areas not friable friable in the first 80 meters, while these changes are not easily detectable by grid drilling.

Deposits canga also offer an excellent environment UltraGPR system, which can be up to 100 meters deep.
