Yes, your right, Thiosulfate Tech was used prior to Cyanide becoming an industry standard. I'm thinking Monsanto had something to do with that. As a point of disclosure, I worked for John almost 20 years ago (been retired 10), so I have seen what he did in the Ag Market. Try to convince growers that his product was better than horsepucky when it comes from a H-waste stream, took some time, but it really is and he really did.
So, if it takes a shotgun wedding between two despicable parties to prove a very real break thru to the Comstock's of the world, then I am all for it. I firmly believe that Hecla, which has a running gun battle with the State of Montana, should be beating John's door down demanding to at least try the new / old stuff.
I'm pushing all in on this marriage.
