I think if you want a stake this close to the intended announcement date for the bulk sample (although it may slide... but we'll know for sure by Friday), you may have to settle for 0.7c
It's a tough call though... if there is a delay, it may very well dip to 0.6c, but you won't know that before they might otherwise make a positive announcement either.
I guess what I'm saying is that after this week it will either go up at least a few ticks, or maybe down a tick, depending on what the announcement turns out to be.
I really cannot tell you how to invest, but it may be worth getting a portion at 0.7c so you at least don't miss the boat altogether if it decides to race. (Do Your Own Research, and all that)
