Those dredging values are based on black sands. Its not based on the overall volume. It should be a small fraction of the overall volume. Until operations are reported we really don't know how much of the 50tons per hour have black sand in it. I would anticipate less than a ton per day with 3 dredges. Still not a bad day, about 8k a day in REE's would be nice. Most of the riverbed is worthless material, only a fraction of it is gold or REE.
