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.

The advantages of soil sampling as a generative exploration tool are numerous. Soil sampling is the process by which underlying, weathered rock or transported deposits are tested for mineral values. Prior to sampling the mineral prospect, discuss with a consultant the commodity, geology, and the erosional/geomorphological conditions in the area.

Companies who engage in soil sampling must adhere to these protocols as well. In mineral exploration, soil samples are typically collected from a specific soil horizon (horizon-based sampling), such as a humus layer (H-horizon), a B-horizon soil or a C-horizon soil. The various layers allow for more targeted exploration for certain metals or ...

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.
