Just to add my two cents worth re the insider selling.
Patrick may have other uses for the 6+ million. In fact, he's currently under negotiations with a South American nation ( one that needs cash) and who knows maybe a personal commitment of a new hospital, water system or whatever may tend to grease the government palms. This may tend to sway the mining agreement in ARU's favor. A small price to pay for the ultimate buy out goal.
Timing is somewhat suspect, but Patrick knows that this info would become public, and yet the market is not having a sell off. In fact the Banks have added positions, since.

IMO
