er6n,

I said previously I would not reply to your incorrect posts.

But I think someone needs to explain a very simple concept that you do not seem to understand.

example...
Mine development costs before production = $100m
This would include workers camp, roads, initial stripping, electricity, trucks etc.

Say Mine life = 5 years.

So DA = $20 a year

***

But you DO NOT have to spend DA of $20m a year as it is already spent!!!

Do you understand now?
