Ores

Ores do not spawn like they do in vanilla, they are much much rarer. Caves will RARELY have ores exposed. Ores are scattered by default and will require extensive strip mining to find. However, localized deposits exist in specific areas where ore spawn in veins (which are interspersed with "vein" blocks such as blackstone and smooth basalt) and are easier to find. There are above ground hints that will tell players where these localized deposits of ores are. Look for rock formations that have high counts of "hint" blocks (described in the table below) to figure out where to go looking! Make sure to mine out a decent area around where you found an ore to follow the vein until its exhausted.

Coal Sheets generate in a similar way but instead of winding veins they spawn in large flat sheets at the same Y-Level. They can be followed much easier then typical veins.

Example of how Veins are generated.

Ore	Hints
Copper	Diorite
Quartz	Calcite
Iron	Andesite
Diamond/Coal	Granite
Gold	Messa
Coal Sheets	Fossils

It's very important to maintain control over localized deposits of ores in the same way that it's important to maintain control over your biome. Keeping other groups of players out of ore deposits gives your community trade leverage to be able to import much needed crops and blocks from other biomes.

Caves

Caves outside of specific ore deposits will have very few if any ores. Finding ores in this event will take extensive searching.
