The ban so far only applies to the Madre de Dios river and not the Marañon river where CMIN fakes its projected operation, but that's only cos there aren't any operating dredgers on the Marañon. However, the chances of Peru allowing one Amazonian river to be screwed forever by scumbags while at the same time banning scumbags on another river are as high as the hole in your posterior has of healing up in the next week or so.
And thus we wave goodbye to Constitution Mining. You guys were great for a laugh and kept us entertained for nigh on a year, but all good things come to an end. Adios amigos, hasta nunca cabrones de mierda.
