This is all speculation on drilling (by TMBXF) which is not too likely to come about any time soon, though they do have a partner for that when needed. While they hold claims, TMBXF has not even announced that they are in receipt of exploration permits, so I think that a large part of this interest as reflected in higherf prices and volumes is somewhat premature.
Let's see how their PPS holds up over the summer doldrums without news.
