Q & A only re March Quarterly, page-404

Well this Q&A is getting quite boring and going round in circles. A lot of off topic stuff normally deleted. SO I'll do my bit and get back on track eh? Having skimmed through the March Quarterly..

On the bauxite front, can I ask (again):

What has the company owned drill rig been doing at Sth Johnstone?
Why were the drill results from the last round of drilling not released to the ASX (May 2015?)
If no drilling for the last 3 years at Sth Johnstone, why did management buy a drill rig?
What has happened with the property option agreements (to purchase land at Sth Johnstone) that were 12 months on signing (2014?) and obviously expired by now?

Thanks.
