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.
