You can find ores normally, yes, but what if there was a way to find a lot at once? Spoiler alert: There is.
With this mod, it adds 7 new dimensions, plus the Ultimate Dimension. The Ultimate Dimension has 7 biomes, one for each ore. Let's go over the new dimensions...
Advanced Swords are used to activate the portal. Right click the portal, as you would with Flint and Steel on a Nether Portal.
Coal Dimension: Literally just coal ore.
To make the portal you need to make the shape of a nether portal, but with stone. You'll also need an Advanced Stone Sword.
Iron Dimension: Again. Pure iron ore.
Make the portal same as Coal Dimension but with Coal Blocks. Also needed is an Advanced Coal Sword.
Gold Dimension: Do I even need to explain?
Again, same as a nether portal but with Iron Blocks. Advanced Iron Sword is needed.
Lapis Dimension: ...
You know the drill. Nether portal, replace the blocks with Gold Blocks. Advanced Gold Sword.
Redstone Dimension: ...
Nether portal shape, blocks of lapis. Advanced Lapis Sword.
Diamond Dimension: ...
Nether shape, block of Redstone, Advanced Redstone Sword.
Emerald Dimension: ...
Nether shape, block of Redstone, Advanced Redstone Sword II.
Ultimate Dimension: Every ore in the Vanilla game put into one dimension.
Nether shape, Emerald blocks, Advanced Diamond Sword.
This mod will create a Creative Tab, containing each sword.
