"We've had survey results out the wazoo. What suddenly makes these ones of significance?"
Sum, we just do not know. We would need to look at the surveys to get a clue.
What we do know is that Noront, not waiting for current survey's completion, has decided on some exploratory drilling in an area that some of us thought that they aquired in a hurry and exchanged a more valuable resource ( In some of us opinion.) for some of it. We also know that there is an annomaly/fault continuation into the area from an already known and valuable resource.
Very curious, Ed.
