The likelihood of a discovery leading to a mine being developed is very low less than 0.1% of prospected sites will lead to a productive mine.

Fine Gold Recovery. Separating Placer Gold Particles from

Gold, being the heaviest element we typically encounter in a stream, can be separated from lighter materials by various gravity separation methods. Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold

An Overview of Basic Gold Separation Methods

Mar 14, 2016 Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore. When panning for gold you put your crushed gold ore in a wide pan and then add water to it. You then swirl the pan around with the aim of removing the lighter materials along with the water.
