The market doesn't like the fact that the area being tested by current drilling is at depth rather than closer to surface which makes mining more expensive?
The point is of course that with a rich deposit it doesn't affect the economic value of deposit as much as one would think. DE tonnage from just the one 'node or pod' looks to be sufficient to justify a mine. Given the current thinking that this deposit could expend for kilometers, most of which is untested, should tell everyone that 'here is a mine' and probably more than one.
Really hard to understand why the market isn't putting any value on this news release confirming things.
