tap alert, dumping before announcement ?, page-10

Could it be the timing was just how it was? Well was almost through on Wed and it is reasonable the final result came through Friday pm. I spoke to Co. Friday around lunchtime and was told they had no further reports, that targets had not been reached in last update and that they would announce immediately they had more news.
I am not convinced the Co. held it back til after the close - it was more than 3 hours after the close. Maybe a leak from the well site, but volume wasn't that high.
Hopefully the fall in price this week will have been sufficient and we won't see a big fall on Monday - but with DOW and oil both off all oilers will be down.

Question: was Manora 5 the least 'risky' because of the closeness to the existing field and therefore easy to bring online, or because of the nature of the play?
