TFCGyres-OreHints
Java mod listed for Minecraft 1.18–1.20. Downloads from the MC Java Mods app on Android.
Lowcode mod to add hint rocks that generate above TFC mineral veins, also buffs some veins that were too rare.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Hint rocks generate in the world above mineral veins just like small metal nuggets from metal ores.
Look for these rocks on the surface where they don't belong, and there's likely a mineral vein beneath:
Adding hint rocks required including the TFC spawn data for mineral veins. In 1.18, I think some of the veins were too small and too rare, so sizes, spawn chances, and some shapes changed!

In 1.20, all disc shaped veins do not spawn indicators due to a TFC bug fixed in . This includes both coal veins and halite. Additional mountainous rich iron veins spawn above y 90, because no iron veins spawn deep.
In 1.18:
Coal veins are now much larger horizontal seams with fewer inclusions. Most other mineral veins are more common and doubled in size. Y-level restrictions are the same.
Recommended for anyone needing better access to minerals.

Also for 1.18, if you're only interested in the vein tweaks, see: https://www.curseforge.com/minecraft/mc-mods/tfcgyres-veinbuffs
If you're only interested in the hint rocks without vein tweaks, please comment below or contact me on the TFC discord.
Thanks to AnodeCathode of TechNodeFirmaCraft for the "hint rock" idea and initial rock selections.
