Ann: December 2018 Quarterly Update, page-10

There were some Nov 18 Options that were priced at 2 cents by my recollection, so the $555K mentioned in the report may reference some or all of those and not relate to the 6 cent options that expire at 31 March. It would seem very strange to be exercising them (the 6 cent Ops) when the price hasn't been above the price in the relevant time frame.

Yes, checked, there were 27,750,000 2 cent options exercised in November as per  ASX notices dated 14 Nov and 30 Nov, which equals $555,000 received.

All that to mention that the trade in shares is very light on at present. People are set, I guess.
