From my lessons in the Sprott 101 geology education videos; visible gold in drill cores tends to indicate high variability in the distribution of gold and is often over hyped in company releases.

I think there's virtually no chance of hitting barren Quartz beneath the mineralised Quartz veins at surface. If anything, it should be a lot higher grade near or at the boiling zones where the metals come out of solution and are deposited in greatest concentration.

10-15 g/t would set the SP on fire, 15-25  is very possible and 30+ we're looking at a top notch world class deposit like Hishikari. It's crazy not to have a punt, IMO. But @Zozac is correct - it still is a spec stock despite our excitement. Please DYOR.
