Or, volcanic hosted metal sulfide... VHMS...

The gold in Shining Tree is either associated with silicates as gold in quartz... or it is in "sulfides" which could include a lot of things, but including pyrite, an iron sulfide. Zinc, lead, copper... could all be associated with VHMS deposits that also include gold...

The quartz stringers you've seen pictures of are apparent on the surface, and some of them contain even visible gold... but, you need fairly high gold content to make it worth mining narrow veins of quartz... whereas lower concentrations in larger quantities are often more easily addressed. Higher value veins paired with wider zones with larger quantities of lower values works to justify mining them together.

The gold melted into and moved along with quartz intrusions tends to occur as isolated bits of gold inside the rock, sort of an oil in water issue, while the sulfides tend to be more disseminated throughout the rocks... more of a water in a sponge issue. Add heat, squeeze the sponge... and you get gold moving from the "sponge" and flowing with the water... where it ends up when the "water" freezes as quartz... maybe.

What they'll really want to find at Shining Tree will be an occurrence of a higher value sulphide target... that has both higher concentrations of gold than the lower concentrations we've seen a lot of, and a whole lot of sulphide containing rock with a higher concentration...

To find that, they're going to have to look deeper... probably more than the 400 to 600 feet down they've looked thus far... and, the concentration will be associated with a gravity high...

That likely means it will be in or near one of the brighter pink spots on that map... perhaps closer to boundaries of some sort than just out there in the middle... certainly still likely to be associated with the fault structures...

And, of course, that map in the link wasn't very high resolution...

Still makes sense that there is a large value in having found higher values in quartz or in sulfides near the surface... as that higher value stuff that got to the surface had to come from somewhere, and that means that it had to come from a source capable of supplying that higher value deposit...

Just considering that... it looks like Platinex's 29 grams per ton and SRSR's 53.9 grams per ton... point to them as having potential finds that might be associated with "the big one"...

Of course, there could be an isolated instance of a high value find showing up here or there, without that indicating a higher potential of association with "the big one"...

So, you'd want to see higher values you find be associated with indications that the materials in the area of that find were a bit more consistently mineralized, and that there was "more stock" to work with... "More" than would tend to suggests something other than just an isolated occurrence.

So, did the higher values come from a single smaller "grab sample" of material that "looked good" and thus was sampled... or do they indicate a more extensive source of higher value mineralization exists, of which that sample might be representative ?

Pairing "a lot of it" with "higher values" is good...

It appears from what we've seen thus far that SRSR might have exactly the sort of things you want to have...
