I have not seen an email that STATES "cannot dredge in the rainy season". Perhaps I am being too literal. Dredge Master has stated that it can be done and can expose new areas that otherwise would not be accessable. I imagine they will determine how many of the dredges are required to proccess the stockpiled sand on land, but also use one or two to explore for more hot spots.
Don't be sacastic CS. He is right. As Dredge has said, the rain raises the river enough to allow the dredges to get into areas they ordinarily wouldn't. I like your initials CS by the way. I think that they describe you very well. You must be a relative of Trader, Pigeon (Hawk), and Chloe. Good to have you ob board squawking your BS CS. Why secure sands with visible gold? We have no clue. Enlighten us CS.
