Gold hides — but it leaves a trail. In this episode of Gold Mining Tips, Andrew explains the science of sampling and pathfinder elements: the chemical fingerprints that point to buried gold deposits. You'll learn what pathfinder elements are (arsenic, antimony, mercury, silver, and more), why they're often easier to detect than gold itself, and how to use them to narrow a huge area down to a precise target.
