- who needs a drilling season this year the most?

I was thinking about this question and wondering what would be drilled this year in terms of exploration anyway. Elmer told me something once in an offhand comment that the Discovery zone wouldn't get drilled again for another 15 years when Schaft is already being mined.

Would they need to drill the waste material to move it into reserves just to prove it to themselves if they have already made the decision to move forwards with the mine? Do they need to re-do the mine pit plan or is that something that is fluid and can be re-designed as they progress?
