How do I edit mine values?

I'm sure this question has been answered, but I've devoted 30 minutes to searching for the answer, and cannot find it. What text file do I need to open up to edit how much money mines give per turn?

Thanks.

Think its this in export_desc_buildings.txt

Its not immediately obvious as the mine_resource is multiplied by 50 so in vanilla first mine gives 4 x 50 = 200 and second 7 x 50 = 350. don't know if multiplier is set anywhere else but changing that figure should change by =+/- 50 per turn. (Oh and there is a funny, that if you have both gold and silver in a region I think you get 2x income from one mine)

U may wish to use a Hadrian building editor.

It works like wonders for me.
