El Oro is underground
past and current administration had special issues regarding open pit mining - el oro is 100% underground so maybe an advantage as time moves on as many mining operations will be idle due to loss of mill feed from open pit mining enterprises and pressure will be mount to compensate - if underground works ok. Will see if they can move forward with the backfill proposal if so - that would be an excellent sign.
Let´s see I would have preferred Xochitl but the populus is always right :)
