A bit of speculation to say that there will be no unexpected costs going forward. Underground mining is still continuing, just at a very reduced rate. DCN may elect to spend more on underground than is in the current plan for the sake of future resumption of UG mining proper. If only 4% of the ore is to come from underground, then why bother at all. Answer is they want to keep it on life support and spend in expectation of a future restart. This will make future quarters less profitable than plan and scupper ideas of early debt repayment. Will know how this goes either way in a couple of quarters.
