I imagine that rehabilitating the mine site ( read as closing down ) is a condition of approval and for some time had a performance bond attached to it. This cash was freed up in July 16 just after the near death experience by giving the state government a mortgage over the Assets of the company.

Not really a decision to close it down and not continue more a tidy up on completion obligation.

The only thing thats a bit weird IMO is that they seem to be spending money in advance of when they really have to.

In your earlier post you mentioned that they had confirmed guidance. The only guidance they are taking as given is the 2018 forecast production and cost range, not the whole open pit guidance that was IMO disclosed by way of the expert valuation.
