Mining Assistant
by Timexo_YT
Mining Assistant puts depth-based ore hints, cave and lava warnings and session mining counts on the player's HUD while they dig underground.
What it does
Mining Assistant is a client-side Fabric mod for 1.21.1. It shows real-time mining information on screen, including the current Y level, chunk coordinates, light level, facing direction and lapis lazuli reference data. Depth is analyzed so the HUD can suggest which ores are most worth mining at that height, and the estimated chance of finding each ore follows Minecraft's own ore generation rules.
The mod also watches the surroundings. It detects large underground air pockets that may be caves, estimates how far away nearby lava pools are, and flags Deep Dark biomes where Ancient Cities and the Warden may be present. Ores mined during the current session are counted, so a player can check progress without leaving the world. The HUD layout can be adjusted to fit personal preferences.
Files are published for Fabric only, with 1.0.0 for 1.21.1 as the single build. Only the client needs the mod, and the MIT License covers the code, which is not open source.

How it compares
Mining Assistant is a client-side only Fabric mod for 1.21.1, released under the MIT License and not open source. Stat Popup Mod is also client-side only and Fabric, but is built for 1.21.10 and is under All rights reserved. OnTemp is client-side only, open source under the MIT License, and covers 1.21.1 on Fabric, so it matches the version but shows temperature rather than ore data. Bedrock Miner is open source under the MIT License and runs on Fabric for 1.21.11, and either side can run it, and neither needs it.
