Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth’s crust.
Does gold replenish itself?
These underground gold particles are few and far between – about one part per million. Even along highly active fault lines, it could take 100,000 years or more for minable deposits to form. So yes, gold deposits can replenish themselves. Unfortunately, it won’t happen during our lifetime.
