Epithermal type gold deposits are among the richest gold deposits in the world, with some bonanzagrade ore shoots containing more than 30 ounces per ton or a kilogram of gold for every single ton of rock mined. These deposits are worthwhile for individual prospectors to seek after. And while the overall tonnage of ore in most epithermal veins is typically smaller than some other types of gold deposits, for small operators like you and me, that can be just fine. They are best mined by underground narrow vein methods. These rich deposits can also give rise to placer deposits. All these factors work together to make epithermal gold deposits ones that are of great interest to individual prospectors.
