I guess consideration must be given to the extraction method.

If near surface, very easy and cheap.
If within old workings, i would say minimual cost.
If at depth mineralisation then cost is more will be significant I think and the bigger the resource the better.

I am probably not as versed in mining costs as others but the sp will heavily depend on the resource size, location of resource and the easy of mining the resource.

As has been previously mentioned historic ore grades in region have been substantial and the old cutoff values for mining were very high compared to todays. This stock will kick if we get back the grades that are expected from it and if we see grades at the top end of the scale well who knows!!!! Not me.
