Makes ore denser the further from spawn you go. It's meant to encourage exploring deep into biter land instead of just sitting < 1000 tiles from the spawn the entire game. It should work with any mod-added ore without any changes required.

Every 3500 distance from spawn (roughly 109 chunks) the ore density doubles. You can change the rate it doubles in the control.lua file - just change 3500 to how ever many tiles you want it to double after. The ore rate scales as the distance does (it's not 1x ore at 3499 and then 2x at 3500).
