There is no such file. The only thing close enough is triggered oregen with GT debug turned on (dont remember if debug1 or 2). It will show in the log just an info that some vein tried to generate. If it was successful or not it will not show.Which log file do I look at to see what ore is spawning as I play the game? 80 shafts without the ore I need is enough, and I'm tired of it. I'm not far enough along to use seismic prospectors.
I remember reading that as you discover new areas, a log file will show you the ore that's generating, but I'm having trouble finding the file.
edit: that file is just normal fml log file (located at the server side)
