nothing guaranteed princepauper but i also see this at 15p close tomorrow. i think they're holding some news which is coming tomorrow or early next week.
in terms of GKP today buys have outweighed sells again, same as yesterday yet the SP has remained 78-82p. Now that the MM's have secured more shares the SP should rise next week to 95p-100p. Drilling is further along that they are letting on as they predicted 4-5months to completion from april. RNS is coming any day on this one which could take it to anything over £1.50.
Obviously just my opinion from research.
