Geochemical Sampling
Geochemical Sampling is a fundamental process used in mineral exploration to find valuable deposits of minerals and metals. It involves collecting and analyzing soil, rock, or water samples to understand what minerals might be present underground. Think of it like taking samples from different parts of a cake to figure out what ingredients were used, but in this case, it's about finding valuable minerals in the earth. Companies use this method because it's a cost-effective way to identify promising areas for mining before spending money on expensive drilling operations. You might also see this referred to as "geological sampling," "mineral sampling," or "exploration sampling."
