An ore vein consists of large, long, streaking collections of ore and a filler rock material. At and above Y=0, ore veins consist of copper ore mixed with granite. Below Y=0, veins consist of iron ore mixed with tuff. They can also contain raw metal blocks.
Ore veins are rare and huge, containing a very large quantity of ore blocks.

|1.17||21w16a||Added ore veins, which must be enabled using an experimental data pack.|
|April 21, 2021||Henrik Kniberg showcases ore vein generation.|
|April 22, 2021||Kniberg mentions tweaks to ore vein generation: the veins are now more smaller and more clumped.|
|April 22, 2021||Kniberg mentions tweaking generation to make the gaps between clumps smaller.|
|21w17a||Ore veins are now slightly rarer, slightly smaller, more clumpy, and can rarely contain raw metal blocks.|
|21w18a||Ore veins were once again made slightly rarer and slightly smaller on average. Their sizes now vary significantly, meaning players can still find huge ore veins like in previous snapshots as well as smaller ones. Additionally, raw metal blocks now generate more frequently within ore veins.|
