In Ouranos you can add as many ores as you want by modifying the value ores in the world configuration.
To do so add a ConfigurationOre property into the list :
- ==: ConfigurationOre
vein_per_chunk_min: 20 # The minimum amount of veins per chunk
vein_per_chunk_max: 30 # The maximum amount of veins per chunk
block: coal_ore # material or blockdata
vein_size_min: 4 # The minimum size of the vein
vein_size_max: 10 # The maximum size of the vein
min_height: 0 # The minimum height the ore can appear
max_height: 320 # The maximum height the ore can appear
