Core Sampling

Term from Exploration industry explained for recruiters

Core Sampling is a method used in exploration to collect cylinder-shaped rock samples from deep underground. Think of it like taking a very deep vertical slice of a layer cake - it helps companies understand what minerals or resources are present beneath the surface. This technique is essential in mining, oil and gas exploration, and even environmental studies. When you see this term in resumes, it usually means the person has experience with collecting, handling, or analyzing these underground samples to help companies decide if a site is worth mining or drilling.
