Soil sampling is undertaken to define the location and shape of an obscured mineralised structure and to identify any higher grade sections within the structure. A successful soil sampling program will result in accurate drill-hole targeting. Many structures are not mineralised to the same degree along their length. A great dea…

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.
