another million.....question

Has anyone been following Emitch in recent times?
Somethings up. A million share parcel at 1 pm today, these big parcels have been appearing as quick one off trades almost weekly of late.

Now if I wanted to pick 1m it could have taken me weeks, with mutiple trades, not too long ago, so how can this happen unless the buyer knew the seller was going to put a million on there and then????

Not complaining I hold this stock and like it but am I missing something.
Could this be a transfer of some kind?
Cheers
Oscar
