Soil sampling is the process of extracting a small quantity of soil for subsequent analysis at an assay lab. The results obtain a measure the concentration of certain metals in the soil which allow for more focussed exploration programs.
Soil Samples are commonly collected and analyzed for various elements by mineral exploration and environmental companies. Interpretations based on the results will potentially direct an exploration company to the bedrock source of the soil anomaly or may result in the recommendation and implementation of a site remediation plan by an environmental company.
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 acts as a pathfinder for some deposit types.
