Because of the altered nature of the till due to soil formation and the possibility that 'soil' samples may include other glacial or non-glacial sediment types, 'B-horizon soil sampling' regardless of the substrate (Fig. 9a–c) is not recommended for mineral exploration or publicly funded surveys.

Soil color is an easily observed property, related to soil composition, and it would appear intuitively obvious that it would be wise to collect material of the same color, if possible, at all sites on a soil grid. Soil color and similar obvious differences in composition can be important indicators of variations in metal content.
