Veinminer — Horizon mod

Mine a whole ore vein or matching tree in one go through Horizon's own player-mining code, keeping loot, XP and tool wear.

Veinminer for Horizon is levzzz5154's unofficial Rust port of MiraculixxT's Veinminer. Break one ore and the connected vein, diagonals included, comes out with it; matching trees work the same way. Crucially, every block goes through Horizon's player-mining code, so loot, XP, tool wear and server block events all behave as normal. It's for survival players who mine a lot, and for server admins who want to offer vein mining.

Features

  • Mines connected veins, including diagonal neighbours.
  • Fells matching trees too.
  • Per-player toggles.
  • Configurable block and tool groups, a block limit and a cooldown.
  • Reads each level's height from the loaded world, so data-pack dimension heights are respected.

Compatibility and install

Native mod, version 0.3.2, for Minecraft 26.3. It's pinned to the 2026-10-31 Nightly (d91cab6) and Horizon Mixins 4342a0b; the launcher builds exactly those revisions, and others haven't been validated. Install it on the launcher's Mods page, press Build and confirm the native-code warning. The launcher fetches its own Rust toolchain and builds a separate game. You'll also need Git and Horizon's platform build dependencies. Our install guide covers the process.

Limitations

Survival mining only, and it belongs on the host or server. Delayed mining, drop merging and Java client add-ons aren't supported. Normal Play doesn't compile mods, so rebuild whenever you change which native mods are enabled. It runs with your account's permissions.

How to install

  1. Find the mod in the launcher

    Open the Horizon launcher, pick an instance on the left and go to its Mods page. In the Horizon tab, find "Veinminer" and press Install.

  2. Build the mods

    In the Native build of … row press Build and confirm you trust these mods. The first build downloads Rust and takes 20–30 minutes and a few GB of disk; later builds take a couple of minutes.

FAQ

Do I install Veinminer on the client or the server?

On the world host or server. It works for survival mining only.
