You started with $ statements but you did not finish.

The bottom line is that if, and it most probably does, continue to 2500 m depth then the known value of Eagle's Nest doubles from present 7.5 billion $ to about 15 billion.

That does not include benefits of in-fill drilling or resource gain from possible extensions of lateral borders, but just from depth alone.

Cause enough to be buying more?

Cheers.
