Perhaps parts of this mod should also influence how easy you can get this uranium ore. As comparing it with iron for example:
|Feature |Iron Ore |Uranium Ore
|Crustal Abundance |~5% of Earth's crust |~2.8 parts per million (ppm)
|Global Reserves |>180 billion metric tons |~6.1 million metric tons of uranium metal

Perhaps the ore processing should give way less uranium or something? and just stone instead?
Perhaps the processing of the ores should already generate some waste products?

We're working on a major 2.0 rework that will improve gameplay balance while keeping the spirit, so some of this may be affected.

Adjusting map resource abundance directly is a good idea in isolation, but messing with resource distribution risks conflicts with other resource adjusting mods. So that specifically probably won't make it in, unless we decide to take on a dependency from another resource mod.
