Why not concentrate on testing the top say 100-150 m and getting a nice open pit resource/reserve worked up.
=========
Maybe they are working out which way to optimise the open pit? It'd be common sense to design the open pit with a plan to going underground. They mentioned something about grid spacing and infill drilling in last months Baloo report, maybe the upper sections have been drilled enough.
Speaking of last months reports... Last month the Sweden results were released a day after the Baloo results. I'm looking forward to seeing what's under the first big Christmas light. Hopefully santa comes early this year with photos of drill core.
