Real, I will address your post this time. You are assuming that AABB must dispose of the tailings on site. But you are not considering that the DRY tailings can be taken off site to a different site, ie the Etzatlan location. Months ago, as I recall, you stated that the Mexican government was very much tightening the legislation and requirements for tailings for a mining business. It might be safe to conclude that , in order for AABB to be allowed to operate a mine project, they MUST include the methodology of the tailings disposal.
That said, I saw one piece of equipment inside the processing plant that spins the tailings to separate the liquid from the solids, as the last piece of equipment in the illustration cartoon, and I see a huge piece of equipment on the exterior, that has a tall and large metal container, sloping down to direct the ?tailings? to a centered drop off to what I assume to be a pick up underneath, to a truck? which may then collect the tailingsDRY, and transport them back to the Etzatlan land, dump it, maybe cover it, and then pick up another load of rock, minerals and etc, to return back to the processing plant. A complete efficient process of tailings disposal.
