A couple of thoughts:
If Tyhee were to be needing to revise it's PA based on updated drill results, wouldn't it figure that they would need to delay it? I imagine that this PA is a very moving target, what with new resource estimates.
Also, if I were in charge, I would be taking my sweet time in releasing this; this sector is pretty dead, a little life recently, but no real volume. Why not wait until there is life here before releasing this? It's frustrating for us shareholders, but the important thing is that new people see the potential of Tyhee, not us.
