Larger Ore Veins: Classic
Larger Ore Veins: Classic changes the size and rarity of coal, iron, copper and gold ore blobs during world generation, using datapack files.
What it does
Coal, iron, copper and gold ore blobs are made larger and less frequent, so each find of these ores is a bigger reward when mining. The changes are plain datapack edits to the configured and placed feature files under data/minecraft/worldgen, and the blob size can be raised up to a maximum of 64. Coal ore blobs yield coal blocks, iron ore blobs yield raw iron blocks, and copper and gold ore blobs yield raw copper and raw gold blocks.
Some ore deposits are concentrated into small blobs of raw iron and raw gold. Server owners who want to adjust the balance edit the count values for rarity or the size values for blob dimensions, and a note in the author text says some files use a rarity filter instead of count, with that change planned for an upcoming update.
The mod is published for Fabric, Forge, NeoForge and Quilt, and as a datapack for servers. Files cover 1.19 – 1.21.1 across 14 release versions, with 1.0.8+mod for 1.21.1 as the latest build. The license is custom and the mod is not open source.
Key features
Larger ore blobs
Coal, iron, copper and gold ore blobs are enlarged, with sizes adjustable in the configured feature files.
Rarer ore generation
Each ore blob is generated less often, so the ores are harder to find and mining feels more rewarding.
Raw metal deposits
Iron and gold can appear as concentrated small blobs of raw iron and raw gold blocks.
Editable datapack files
Sizes and counts are changed by editing JSON files in the datapack, without installing any code.

How it compares
No More Copper Ore has the same Fabric, Forge, NeoForge and Quilt loaders and covers 1.19 – 1.21.1 under the MIT License, but it targets copper rather than the four ores this mod changes. No More Nether Gold Ore also is needed on the server, with the client optional, under the MIT License, but covers 1.20 – 1.21.4 and only nether gold. Diagenesis is open source under the GNU Lesser General Public License v3.0 or later and built for 1.21.11 on Fabric and NeoForge, a different scope from this datapack.

What the author says
This simple datapack changes mining to make it more rewarding when you find coal, iron, copper, or gold. The size of the ore blobs has been greatly increased, but have also been made less frequent to balance it out. Copper ore blobs have a chance of generating raw gold blocks
