Jaynor's Gold Digger: Makes solid gold for 25' an ounce.

i ~ ¸

NO more refining of solutions or burnable resins. Just send metal. Like all great ideas, the Jaynor Precious Metal Recovery System--the Gold Digger--is simplicity itself. Instead of using bulky resins, the 38-1b TV-sized Gold Digger attaches to your dragout tank and plates the metal out on a cathode panel. The metal is 80% to 90% pure. Start mining solid gold! JAYNOR can design and build a custom Gold Digger to fit your specific needs.
