Of course you can't take dirt to a smelter. But you can take gold-bearing rock to a mill. And guess where one is located? Nearby Philipsburg. A refurbished gold mine outside of Helena currently digs rock and trucks it to Philipsburg where it is milled and then it's sent elsewhere for smelting.
Not saying Dutch Gold will do this...it's just that it's possible if they come up with bonanza grade gold.
