denben, rob has it nailed.

Alternatively if you have time - I was going to suggest the best method is to read the company's announcements in detail (both drilling and geo reports), look through historical data in the area and more importantly reading the coal reports already made public (mind you made public quite some time ago), and then come to a conclusion.

The term strike rate just doesn't seem the appropriate terminology right now and, the comments made earlier saying "its just enough to be profitable...." is very vague IMO
