Has relatives on Oregon coast; what about TAE process for saving fine gold. Cost? Marg: "Our machine is to work pure black sand containing flour gold which is found at many places along the Oregon Coast. But there are some deposits which contain so much silica or quartz sand mixed with the black sand that it will not pay we sell the machine at cost & take a royalty on the profits guaranteeing it works."
