that was the gunk put in the vat iirc.
Huh? 40,000 tons of uncrushed rock, contaminated with cyanide, scooped off the leach pad, trucked 200+ km. to Ures, and squeezed into a vat that probably wouldn't hold 100 tons?
No, it was not the gunk put in the vat.
Do your own research, use third-party sources, and don't buy into the hype.
