You’ve seen it before: copper and zinc together to make brass! What MeanCloud has done here is extended support for ore-laden sub-biomes by adding copper and zinc metal boulders and vein generation to the random world generator. You can smelt these meterials together to make brass directly in the forge. Additionally, he added automated mining excavators (inspiration and permission from stallionsden’s mod) that will automatically produce a variety of raw ores, stones, and even asphalt, gravel, bones, soil, and glass. But the cost to make them is steep.

After retrieving raw ores, you can use the new rock crusher machine to crush them up for you into usable resources. Finally, lots of effort has been made to add copper and zinc as salvagable metals throughout the game from appliances to metal piping as well as automotive pieces and chain-link fences. This mod gives you plenty of options for finding new ways to get brass for all your munitions needs, not to mention all the other ores at a reasonable pace.

How to Use

To get started mining, MeanCloud highly recommend you create a new random world. If you try to install this mod in an existing game, the new copper and zinc ores and veins will not be generated. You will still find copper and zinc while salvaging and scavenging, but you will not find it while mining unless you create a new random world (see notes further down in this post). Once you’ve found some copper or zinc to mine (or have otherwise looted some), take it to the forge and you’ll find that it now accepts the additional metals which can be smelted down into scrap brass or forged directly into bullet casings. Note that you still need the relevant perk to craft bullet casings and the crucible to pour brass back out of the forge as normal.

This mod also adds excavators, which are automated mining machines that will drill into the ground and resurface with materials every so often. While they are expensive to make, they will surely make up for their cost in the materials they mine up. Most of the mined ore must be processed by a rock crusher, which this mod also adds. The rock crusher is a new workbench (it looks like a cement mixer once placed) that uses ore blocks and sand to crush the usable materials out of the ore.

Excavators will go through various stages as they mine through the ground:

Important Notes

Important notes you should read:

Note for Multiplayer

The current version of Alpha 18 does not push localization data to users. If you are playing multiplayer (either hosting or via dedicated server), each player will need to install the mining mod themselves to get the proper descriptions of items, blocks, UI labels, etc. that this mod changes.

Note About World Generation

This mod adds ore generation in the form of sub-biomes for copper and zinc metal boulders and ore veins. If you do not generate a new world, these boulders and veins will be absent (but you can still definitely acquire copper and vein materials by salvaging and scavenging during normal gameplay). He would recommend that you start a new game if you intend to use this mod.

Additionally, He is not a graphic artist and did not design 3D models for the copper and zinc metal boulders, so He is re-using the game’s assets for the lead boulder and potassium nitrate boulder. There’s no way to tint 3D entities, so they will unfortunately look exactly like their counterparts as you encounter them in the world. Sorry about that, if you are a graphic designer who knows how to add assets to bundles and you’d like to donate some of your time to provide assets to this mod, He will be more than happy to chat with you about that and give you credit if he use your assets.

Note About the Forge Changes

If you are adding this mod to an existing game, please be aware that your existing forges will have all contents erased except for fuel and anything that was queued. This is because this mod is adding extra input materials (copper and zinc) and the 7 Days to Die game engine does not gracefully handle this kind of change. Make sure you’re okay with all players losing forge contents the first time this mod is installed into an existing game world.

Note About Mod Compatibility

This mod is not compatible with stallionsden’s Rain Catcher and Mining Machine mod, which uses some of the same block names and lootcontainer IDs.

Additionally, this mod is not compatible with the S420’s Simple UI Forge Input mod that changes forges to have three inputs. This mod already includes forges with three inputs anyway, but S420’s overwrites what resources are accepted by the forge, causing errors to be logged to the console since this mod requires copper and zinc to be accepted by the forge.

Errors on Startup

If you fail to install the prefabs correctly, 7 Days to Die will log errors in the console window. You need to install the prefabs to the correct location, even if you aren’t generating a new world or are playing on a dedicated server.


  • The existing 3D models for the copper and zinc boulders have been tweaked.
  • A new 3D model has been added for the rock crusher workstation
  • Bullet casings now craft faster (1s per casing)

How to Setup

Download and extract this mod to your 7 Days to Die /Mods folder.

For Steam users, that’s \steamapps\common\7 Days To Die\Mods (create ‘Mods’ if it doesn’t exist).

Once extracted, move the files in the mod’s /Prefabs folder to your 7 Days to Die /Data/Prefabs folder.

For Steam users, that’s \steamapps\common\7 Days To Die\Data\Prefabs (‘Prefabs’ will already exist; if you can’t find it, you’re in the wrong place).
