shares tightly held and sell volume decreasing

The sell total volume this morning has dropped about 600k from yesterday.
Few sellers which is to be expected with the plethora of news expected and the details of the bonus shares and free oppies some time to be announced.
The occasional person might have to sell for a variety of reasons but the pre consolidation prices were the equivalent of around the 29c to 30c level. Post consol' high was 35 c from memory.
A sale went through yesterday of the GDAOA ( GDADB during deferred settlement) at 5c which was a surprise and is an equivalent converted price of 55c. Maybe there is something I have missed ( or the buyer missed)?
The ten fold reduction in the number of shares on issue means there are only about 58m shares listed and for only 474,000 to be listed on the sell side looks like they are being tightly held for the bonus issue and free options.
