The continuous disclosure requirement has always been a grey area, and it would be extremely difficult to prove the company has acted in violation of this, especially with regard to a PFS or independent valuation report, and I don't know what you would hope to gain by doing so.
It's rare for junior mining companies on the ASX to stick to their timelines, hotcopper posters are always complaining about late announcements etc, it's very common.
As has already been covered, management has 15 days to respond to the proposed takeover once notified by Aurenne that the bidders acceptance statements has been sent to all shareholders, this has not occurred yet.
The takeover process is often long and drawn out.
