Mix Veins can generate only one vein per 3x3 chunk area, however Mix Veins can contain hundreds or even thousands of blocks of ore. Mix Veins can contain up to four different ores. Vein contents are dependent upon height and dimension, but are not dependent upon biome. Veins can range in size from 16x16x5 up to 80x80x8 blocks, with very few and small gaps between ore blocks. However, ore veins can only generate where they have Stone, Red/Black Granite, Netherrack, or End Stone that can be replaced by ore blocks.
