The pit has been professionally maintain since 2012 and still going, page-70

Thank you for your permission for me to add to the discussion.

You say: "so let's stop asking stupid questions constantly, do you have any references or resources saying what ever NAMA is doing can't be considered a form of maintance?"

Surely the question is, given assertions by others, whether I have any references saying that NAMA is maintaining the pit. I don't. NAMA has not replied to me.

That Wiki reference you posted is useful. You say it defines maintenance of a mine as the undertaking of certain duties. What are those certain duties?

"During a care and maintenance phase, production is stopped but the site is managed to ensure it remains in a safe and stable condition."

"While the mine is closed, a care and maintenance program will manage environmental risks associated with tailings dumps, hazardous materials and open and underground pits."

So is NAMO doing this? I don't know, but I hope they are.
