We demonstrated in last month's newsletter how water can be gravity-fed off the mountain to operate gold recovery systems without the use of motorized pumps. The single drawback to that method is that you have to locate a rich deposit of gold near to where there is a source of water flowing from the hillside – or perhaps a pond of standing water from which water can be …
