....this, that shows what percentage of the total gold produced in Peru comes from Yanacocha (NEM and BVN) plus the two big Barrick (ABX) operations (Lagunas Norte and Pierina).
Even if you don't find this as interesting as me, it does at least give you an idea of what sad mining numbers wonks get up to when let loose on a dataset and XLS. But just as a quick word, it shows that the recent slump in Peruvian gold production is very largely due to these three big mines. DYODD, dude.
