"these intersections are bringing direct shipping ore from surface"
That may be stretching it a bit .
AW1 have been pushing that barrel with their ore sorting approach , but I doubt if it is viable for them as they did their ore sorting trials on selected high grade samples rather than the average grade of drill intercepts , high grade feed into the ore sorter does not give a fair representation of what the average grade the ore would be shipped out at , really need to get samples that represent the average from the full population of samples intercepts
I would think a standard high CAPEX flotation plant proposal will be what both companies end up with in the long run to get the ore to a concentrate with over 30% Cu in it , I can not see an ore sorter doing that on say an average grade processed of 3% Cu , maybe an ore sorter can get to 10% (without excess rejection) but not 30% or more which is needed to keep transport costs to a smelter in probably Quebec/Europe down .
