It was all about a share picking subscription mob (Port Phillip Publishing) putting a buy reco (up to 9.6c) on MEP last week post trading halt. I believe they have a few followers which accounts for volume. Unfortunately, that volume will eventually need to sell if MEP can't kick goals short/medium term.
I usually sell into these type of mobs, but I believe MEP are the class in aussie exploration so will let the short term profits go for somewhere down the track when they actually drill something of significance.t
