OreOverlay
by armi1014
With OreOverlay, players can see where ores are likely to be before they dig, using the world seed to mark candidate spots on screen.
What it does
OreOverlay predicts the locations of nearby ores from the world seed and draws them as colored in-world markers. The markers stay visible through terrain, so a player can plan a route to a vein before breaking any stone. Once a matching block is mined, its marker disappears, and the hidden and mined markers are stored separately from the visible ones.
The mod is a Fabric mod for Minecraft 1.21.11 and is client-side only, so a player installs it alone and servers need nothing. It works without changing server behavior, because it adds no server-side code. Its data can be reloaded in game without restarting, which lets a player apply changes to the overlay data on the fly.
OreOverlay is open source under the MIT License. Its source code and issue tracker are public. The latest Fabric file, 1.0.0 for 1.21.11, was published on 2026-03-15 on the beta channel.
Key features
Predicted ore markers
Nearby ore locations are estimated from the world seed and shown as colored markers in the world.
Markers through terrain
The colored markers are rendered through stone and other terrain, so buried veins remain visible.
In-game ore search
A search menu lets a player pick a specific ore and load its results immediately.
Mined markers removed
A marker vanishes once the matching block is mined, and hidden or mined markers are saved separately.
Reload without restart
Overlay data can be reloaded while the game is running, so changes apply without closing Minecraft.

Who it’s for: Players who want a visual guide to ore positions in singleplayer or on a server where they install the mod on their own client.
