    The difference between these techniques is easy to understand. The first gold seekers were lucky enough to stumble upon ores, or impure forms of gold, that were directly accessible from the Earth’s surface. As mining progressed, the ore deposits began running out, making it necessary to seek them deeper inside the ground
