The old guys reached the "nameplate" capacity hence "nameplate" capacity. Or is that another conspiracy from when you were there? Since then MKR have upgraded the circuit a fair bit.

The already mined stockpile was claimed to have ~75g/t and it is yet to be determined if that is true or not, more posts in the other threads offer insight into that. If the ground they choose to mine is >100g/t then it is significantly better than the stockpile and will recoup some of the extra costs from needing to mine and move it a few hundred metres. No one here right now can tell you if any of these things are fact or not so people pretending to do so are usually somehow invested in a salt mine nearby.
