My take on the increase in drills could be that they are 'pressured' by the big share holders to generate results soon. If you hold million of dollars in stocks, you don't want to wait around for a long time. Remember time is money. I am sure the big guns are as eager as the rest of us to get some good news.
8 drills to me also means that the management is realy expecting to hit something of economic value. If you can't hit anything real with 8 drills going, the SP will drop quickly and the management will loose big, more than us.
Lets hope their gut feeling is good
