@NeilRingdahl Great post. Such a specialized task here. The number of high capacity shafts at +kilometer depths globally would be very few, these ones are huge, what a challenge.
@tombszabo@TheWealthMiner This is a good point, as you cannot close a HL site without rinsing the pad. And you can not rinse with a broken liner, so government will be incentive to permit the 2nd facility if not only to close the site properly.
@tombszabo@NeilRingdahl@Critical_Inv@J_Wise_geology The fact that we see flowing landslide debris almost 1300m away suggests that the in heap pond did fail. This was the saturated material that flowed 1300m. The rest of the material sitting above the pond was not saturated, evidenced by the steep slope along the failure surface.
@BuckBandura@TheWealthMiner Not recoverable until they build a new HL pad and get a new permit to leach with cyanide. But that is not going to happen, they will write it off to zero..
@duediligenceguy For cleanup, there is no way you can start at the bottom, it needs to be taken top down.. so where does all that cyanide laden ore go? A new pad is necessary... costing $$$$ they don't have..
