QQ,
You wrote, "I also wondered if it was a direct message to the "big boys" - back away ! ?"
Can you elaborate on that thought?
The reasons I can see for an NI 43-101 delay (all speculative) include:
1) The delay in receiving assays has pushed it back.
2) Management has decided that DE1 has the potential to be much bigger than they thought (remember the in-hole em testing and the em bursts they have been conducting,) and they would prefer to wait and come out with a much bigger resource. (very good news)
Naturally, any other mineralisation discovered - DE2, DE3 and the 'ghost bridges' would be in addition to DE1.
The downside is that listing on the TSE may also be delayed.
