Question about HAV

Dear HAV Holders, I have a quick question: I owned HAV years ago and held it through several market gyrations, but nothing ever seemed to happen on Kalkaroo so I gave up on it. I still look in on it occasionally but there doesn't seem to be much progress.

Here's my question: in the current hot market copper for why are they stuck on a market cap of $68M ? I seem to remember a major looked it over a few years ago, but passed. I could trawl through all the annoucements but is it management ? Or is there some problem with Kalkaroo ? I met Chris Giles twice and found him likeable in a mad scientist kind of way; there was no doubting his commitment though. Apologies in advance for this slightly lazy approach but I suspect current holders will know the real story.
