EC interesting point; full grind ore. I assume you mean crusher, grinder, ball mill? Isn't it easier to leach PM out of a fine sand or silt size particles versus course sand to fine gravel, which is more 'typical' of a heap? Just seems like the greater surface area of a well ground ore is going to lead to a more efficient process, no? Then isn't it easier to keep cyanide contained in tanks with secondary containment versus plastic lined ground? With a medium grade, full grind ore, I would have no trouble at all designing a no-cyanide mill that got 95% recovery with lower cost than cyanide. I could even use 1870 technology to do it. So why doesn't CAU just switch their extraction process, rather than waste all of that money with lawyers and Supreme Court hearings? Or is this a function of a dated mentality? H3
