    Plough
    A few points you may want to check from your earlier post.
    Cutof / grade relationships dont include hangingwall/ footwall waste in a resource estimation. I am pretty sure this is the same for internal waste but happy to be corrected.
    It does in a reserve calculation, but that is internal waste. I might not be picking up on your meaning here.
    Why did you pick 0.12% grade for your calculation?
    Funny though that if you where Moly mines you would be crowing about that grade as their head grade is about 0.05% Mo on a good day.
    So how does it work for them? Could it be a combination of strip ratio, metal value , processing cost, plant size etc etc,etc
    What if you had picked 0.14%, 0.16% etc etc .
    Isnt that the work of the ore reserve, mine design, project economics teams.
    Again i suggest your approach is a good starting point but it is pretty simple and would cut out a lot of mines that are economic.

    With the DSO sleeper and the long term nickel, I am happy to hold.
