Look for the bands of black sand and test them. When you find a good section of black sand that has a high amount of colors in it that is where you need to look.

Jul 22, 2020018332When gold found in black sand comes in the form of small nuggets and flakes that arent attached to any minerals, they can be sifted and separated through the use of machinery like a shaker table, a process similar to the panning used by gold prospectors.

The containers would then be filled with black sand and brought away from the surf where it could be piled up and then separated. Since wave action literally changes the golds location overnight, each day a new search must be made for the iron sand.
