I have no idea as to why they waited so long, possibly rig availability. Would be hard to get someone to mobilise to a remote location do a 1000m RC job.
The hole depths don't really add up either, they say 33 holes for 990m which is an average of 30m/hole. The are not showing those sort of depths in their tables, unless they are only showing the mineralised parts of their holes. They have most likely drilled shallow holes as a first pass to asses the higher grade parts of the sequence with a view to focus later deep drilling on the more prospective parts. This way they can assess which of the bands within the steep dipping sequence are more iron rich. I would be more worried about a company that leapt in and drilled 10,000m of 150m deep RC holes on a few rock chips.
Another reason may be that the rig they managed to get was a piece of crap that could not successfully drill the banded iron.
