"And of the 5 holes reported, most hit gold."

That is important. To mine 0.4 grams you need really good metallurgy and lots of the stuff. Rip and heap leach only gets 70% recovery, if that, ignoring the nugget effect. Full milling in that grade would require a 50,000 tonne per day mill. Remember that is $8.35 ore!! Scale needs are major.

In truth they need at least 1 gram to start gaining attention. The large Canadian gold open pits are approaching 2 grams. We have one that is 11 million tons of 2 grams. We don't intend to open pit it, though.

1 gram may be possible with nuggets. 20 dollars stuff can be handled with moderate scale of perhaps 15,000 to 30,000 tons a day full mill. Rip and heap leach at much smaller scale. If the ore is refractory as many Pac Rim ores are, they need some special flotaion treatment or large scale roast or autoclave. Can be done. Just have to know what you are doing. Geos are not always up on this stuff.

It's early stages on the probing work to depth. Lots of strike to play with. Hopeful hands might take a moment to reflect at the pew that Aurelian found a mighty capped deposit about 2 kilometres from a one kilometre long one gram fairly wide zone that was attracting no attention.

To compare the present SUR thingie with some more advanced drilling plays that went after good channels and pits, look at Strata Gold and SMC or Sacre Coeur. For my money right now, I would put those two ahead of SUR. Just my bet so far.
