I see they have upgraded the access to the bottom of the pit per the latest ASX announcement (24/6/2015); the Sept 2014 Q states "In addition considerable effort continues to be spent cleaning up sections of the pit which have deteriorated during the C & M period"; however the June 2014 Q states nothing about pit deterioration; the words "considerable effort" to me denotes large scale effort; however how could pit deterioration be missed & not reported in the June Q when mining recommenced?

So from following the trail of ASX announcements from June 2014 to current; could a possible conclusion be drawn that the "considerable effort spent on sections of the pit which deteriorated during the C & M period" was the upgraded access to the bottom of the pit? If so why does it take 12 months to elaborate on the pit access upgrade project it just seems to appear out of the blue in the latest ASX announcement.

To me; pit access information seems to be important information in regards to ore production and the value of the SP.
