... took too long to start drilling ...... and here we go dowwwwwwn ... egad, you'd have thought the start of their drilling campaign would be perceived as good news, but on second thought ... maybe they've been way too slow at cranking up the drills, and investors decided it's too early to expect any drill results (with assays) for awhile since drilling is only starting now.
In other words, Pretium should have started drilling much sooner than this, so the stock price is being punished.
