andres,

Quite correct. The financial model wouldn't suddenly magically extend for the increase as "bonus tonnes", those tonnes would have already been accounted for in the mine planning given the existing certainty. But it does add shine to the SDL story.

Westcott, there is no such thing in the mining code as Reserve Resource. As you have mixed these terms before - you might want to refer to
http://en.wikipedia.org/wiki/Mineral_resource_classification for a clear explanation.
