I disagree. DD can lead you where you want to go. No better example of that was with SAEI recently. Much DD done and many honest believers..Yet that turned out to be a total scam..
Here, I have no doubt katx is not a scam, vale proves that, imo. Capability and properties are in great Question however, imo.
But, DD lesd us to HC being a Huge Gold find DD lead all to believe RR was the next Olympic Dam As 2 examples
The PPS also says maybe all the DD done is Not a Fact
