The chemicals used are cyanide and mercury, there really is no way to recover from an “event” as a dam breaking holding back the sludge pond, We live with just such a threat above us in the Ameca watershed from just exactly the same potential from San Sebastian, sadly the folks at mine, Canadian, know how to conduct procedures responsibly…but do not do so properly, a series of ponds with traps where chemicals known as “floculants” attach and catch mercury and cyanide would be how responsible mining is done, but corners are cut and this is what happens….disaster, cancer will be legacy there now, how the Ameca watershed is cared for is a question.
