RE:RE:RE:RE:Patience is the name of the game. No follow up? That is a question for IVN to answer, I can only speculate.
I think the fault line / strike (175km is kind of large) with multiple strata of copper that they found, is well understood.
The magentic surveys, and gravity survey have likely confirmed size and the presence of copper. It's location may make it a logical extension to K&K.
It might have been as simple as IVN wanting to know what else they have first.
IVN have been in talks with other interested parties, regarding WF, for a few years now (more than 2, if my memory serves me well.)
I speculate they either want to find, or believe they have found, another tier one potential. I am guessing it is south west of K&K..... time will tell.
WF is 5.5 times larger than K&K (only half of K&K has been drilled.)
There is a lot to do, to find out what they have. I actually think they are things in the right order. No big shock from RF there.
The expansive exploration mentioned in Feb 2021, was explained in this year's March report, and it was expansive. The drilling they said they would do, was done, and explained.
What IVN have not said, is why they have made certain decisions. They have been a tad coy over some matters.
Time will tell.
