"I am not a, mining person or geologist..."
I bet NAK has quite a few geologists, and they probably answer to others from HDI or AAL these days.
These folks probably know Briscoe was right about the caldera being the source of mineralization in this region. That recognized, one could assume there would be a lot more untapped deposit, even without the ZTEM or the biochemical analysis of surface vegetation.
So NAK geologists would probably see all these factors as correlating data, each adding up to shift the odds of major gold and copper into the highly-likely category. You don't have to be a Nobel laureate scientist to understand that volcanoes are likely to create large mineral deposits. It's all there for those who want to read about it. The odds go up for Pacific Rim volcanoes, proximity to existing deposits, ZTEM, biochem analysis, and basalt igneous composition. This is a textbook scenario for huge amounts of valuable mineralization.
And when all this is proved out to whatever degree, I will be holding a fat stack of shares. I hope you are along for the Big Ride...
