Interesting proof that big cobalt deals are going on in secret, page-22

2: There is no shorting going on according the The Shortman website.

Unsurprising as small caps outside the ASX500 generally arent on the shorter's radars.

4: . My conclusion - dozens of people know what is going on behind the scenes (at the engineering consultancies etc), some of them may also inside trade, but we have no evidence of dumping shares or shorting, only of accumulation.

Thats just stating the obvious. There are always people 'in the know', and Insider trading goes on in all sort of ways at every level because it is not hard to disguise and nor difficult to get away with.
