Ore Caves
Ore Caves are different types of caves that were added in version 1.0.27_X4186. These caves contain different types of stone and resources, and take the shape of existing vanilla formations.
Ore caves come in 2 variants.
- Caves, which take the shape of existing caves and contain features such as stalagmites or acid.
- Strata, which are mineral deposits replacing large amounts of stone.
Caves
Caves are formations that replace existing caves and contain features such as pools of acid or stalagmites. These caves can be used for large quantities of a resource such as 
asbestos but are commonly hazardous.
Sulfuric Caves
Sulfuric Caves are a cave formation composed of sulfurous stone and sulfurous stalagmites, containing small pools of 
sulfuric acid on the ground. These caves are a very large source of 
sulfur and can be used to obtain sulfuric acid before a chemical plant.
Chrysotile Caves
Chrysotile Caves are a cave formation composed of chrysotile, a rock containing asbestos. It contains features such as asbestos stalagmites and stalactites. These caves are a very large source of asbestos, however it contains particulates which can cause mesothelioma.
Strata
Strata are large deposits of specific, valuable rocks that replace stone. These deposits can be processed for large quantities of resources such as 
iron or 
copper.
Hematite
Hematite is a brown-reddish rock containing iron minerals. Hematite deposits are typically very large, ranging from 300-1200 blocks. It can be smelted in a 
Crucible using flux to produce iron and slag.

Malachite
Malachite is a bright teal rock which contains copper minerals. In comparison to hematite deposits, malachite deposits are notably smaller. It is processed in an identical way to hematite.

Bauxite
Main article: Bauxite Processing
Bauxite is a bright orange rock, and contains a variety of resources, primarily 
aluminium. It has a multi-step processing chain which depending on the process used, can yield large quantities of aluminium, and byproducts of iron, titanium and mercury.
Schist
Schist is a muted blue rock which forms in distinct bands. It typically contains much higher amounts of ores. They also have 
lithium ores and 
gas shales containing 
petroleum gas which are exclusive to schist strata. Graphitic schist itself can be acidised or shredded to produce lithium.

Trivia
- Processing of Hematite and Malachite was nerfed from 2 ingots yield down to one in update
X4774.Malachite veins were adjusted to be larger to compensate the nerf, but it's still a pretty subpar way to obtain copper despite its "buff". - All mineral deposits generate between the Y levels of 64 and 6
- Bauxite can be easily confused with lava, as the texture and color pallete are very similar.
- Bauxite is considered to be the best deposit block, as it yields multiple first-hand materials.
- Lithium schist ore is very important, as it can be acidized to obtain lithium crystals, used on many recipes such as the Overclock Upgrades. It has the
Hydroreactivetag, which means it will explode when in contact with water. Beware of rain for this reason. - Upon mining your first schist rock, you'll be granted an amount of XP and the "Stratum" achievement
There is a very low chance that the sine waves cancel each other out and result in little to no strata forming at all.- With a new update switching to perlin noise instead of sine waves, this should not happen.
