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.

Geological sampling is crucial in exploration, offering cost-effective ways to identify mineralized zones through soil and rock chip sampling. These programs help target drill sites accurately and prevent unnecessary drilling. Sampling can be based on a grid, mineralization structures, or geophysical anomalies.
