Salta has a different EIA process timetable than Catamarca hence one cannot use the timelines of Galan with what Puna Mining will undergo. A better fit to what happens to Puna Mining is to find out what the timeline was for Rio Tinto. Unfortunately, the date of publication of the approval is not the same as the receipt of formal approval and this was not announced by RT. As regards Eramet, I am aware they have a pending EIA application similar to Puna Mining that is still being studied and not in the stage where Puna is. It looks like Puna mining gets its EIA approval with Posco next then Manufactoras Los Andes in Salta Province.
It is not true that no one was aware of Puna Minings public hearing timeline. It was published as a public notice in 3 consecutive working days in Spanish detailing where the application details could be viewed, when the deadline for submissions was and the time and date of the public hearing.
