Keep in mind ATN is very much a spec stock, so the price can be volatile in either direction even just on gossip.
What I've found is that with a keenly anticipated event like drilling commences, interest in the stock starts to increase so we might see a bit of a rise up until the first results are released. Then it depends on how good they are. Even if they are good, if it is at or less than market expectations, we'll probably see the price drop.
But who knows? Sometimes this is nothing more than gambling.
Personally, I've been watching and holding ATN for a long time and this is the first project where some real value seems within our grasp.
One of the brokers put out a report recently (I forgot which one) - it's worth a read.
