Hi ML,

Have a look at the Helmsec research report from 2011, page 4; it gives you a nice peak at their Finland operation.
What I found in a diagram is that they based the Outukumpu stydy on 4,3 Mt ore reserve.
Their measured and indicated resources are 10,4 Mt and an indicated resource of 7,36 Mt in the satellites.
This all for an indicated minelife of minimal 10 years !
As the Kylylahti mine is open at depth with increasing grades at depth, and also three satelite deposits showing potential for feed, the minlife of 10 years seems to be no problem !
Even with upscaling tp 800 ktpa ( and even 1 Mtpa is mentioned) for a very modest amount of 5 to 7,5 mln $ (upgrading the mill) minelife is secured.

Meanwhile having a coffee in Helsinki, I hope this helps you.
