Historically there is little if any mention of Gold in the Cleveland, Tennessee area. However, thus does not mean that it does no exist in some streams and the soil. Since Cleveland for the most part sits in the Tennessee Valley which was pretty much carved out by the Glaciers as the made their way to the Gulf of Mexico and/or Atlantic, there is surely some Placer Gold that was deposited. Also, since Cleveland is not far from the Western portions of the Appalachian Mountains and not far from known areas where Gold has been found, it is quite possible Gold was deposited in the area. This is due to the Volcanic and Tectonic Plate activity which cause the Westward of the upheaval which pushed rock layers, minerals and other compounds including Gold as well as even some mountains West and Southwestward into and across parts of Tennessee. You might want to test some stream mainly to the Northeast through Southeast of Cleveland to see if you can actually find some Gold.
