i know this is how its done... but how will STB be able to achieve meaningful rates if the surface area is not large enough? thats what i mean. to achieve 400ktpa you are going to need a surface area as large as RWD... could you make the surface area of ponds in the sand as big as them?

if you do it over a smaller surface area the mining rate will be slower and then the mine pay back is going to take a long time....
