300 tons p/day, your kidding right.No way they will produce 30 oz per day not even close and from a placer mine the smallest, least productive mine of all...Real mines don't even get 30oz from 30 tons...But the assays have not been done or completed, and IMO no one will ever see them because they will show this one for what it really is.
But by all means don't take my word on gold amounts per ton, that information has been posted with links showing the facts. Look them up, or do some real DD on the subject.
