Ore-Vein-Generation
by imcasper
Ore-Vein-Generation replaces scattered single ores with large underground deposits that players can find while exploring caves and mountains.
What it does
The mod changes how ores are placed in the world. Instead of small pockets spread across a chunk, it generates continuous structures that can span several chunks, so a deposit is large enough to justify building outposts, railways and logistics networks around it. Six deposit shapes are included, among them a sphere with scattered uneven pockets, a wide, gently undulating horizontal sheet that follows the ancient landscape, a tall and narrow twisting vertical pipe, and a large nearly uniform spherical body. Density can vary randomly inside one body, creating ore-rich zones next to empty voids.
Generation is fully configurable through JSON, covering the shape, density and placement of each vein type. The author notes that other ore mods can be added with a few lines of configuration. The mod is for Fabric and is server-side only, so players join a server running it without installing anything. It is open source under the GNU General Public License v3.0 only, with a public source code repository and issue tracker. Files cover 1.19.4 – 26.2 across 19 release versions, and the latest Fabric file is 1.4.0 for 26.2.
Key features
Massive rare veins
Rare ore deposits large enough to span several chunks reward players who travel far to reach them.
Six distinct shapes
Deposits take six forms, from spherical bodies and bullseye-patterned cores to vertical pipes and flat sheets.
Realistic mineral placement
Deposits follow natural terrain, such as curved layers traced across the landscape, instead of appearing as uniform clusters.
Exploration incentive
Caves and mountains become worth searching because deposits are concentrated and hard to find.
JSON configuration
Shape, density and generation settings for each vein are exposed in JSON files for server owners to edit.

What the author says
Ore Veins introduces a new generation architecture for ore deposits. Instead of scattered ores in each chunk, the mod generates continuous structures — from small pockets you can mine in a few seconds... ... to giant formations spanning multiple chunks. These colossal structures are rare, but when found, they provide…
