nothing new hereThese guys are great promotors. Cyanide alternate reagents have been around for decades be it chloride, bromine, or like Enviroleach with iodine. Technically they have always worked well, although some have environmental limits as well. The problem is cost even if regenerated. Cyanide can be regenerated, but they dont do it because of cost. Their small, very high grade application up in the Yukon doesnt matter when you look at the value of a gravity concentrate feed. Applying to insitu large volume low grade good luck if it cant even be done economically in tanks, by others (except for a small very high grade feed). If these guys publish a detailed economic study of their ISR project with independent oversight and it looks good I may become a beliver. Until then could be another in a long list of cyanide alternate promotors that fail.
