Having been in this stock for many years this is typical pre news action. I read nothing into this volume or small price increase. This is normal gambling on better results in an upcoming NR.
We may or may not get better deep drill results, however it will never stop the gamblers from placing their bets.
KXL will continue to be a crapshoot attracting the like.
We may or may not hit a homerun. At these prices you have to decide on the pot odds.
