List of Ores

Ores are basically mineral bearing stones. It drops items out as you mine them. There are at least 80 ores in Minecraft Feed The Beast (83 usually) included BiomesO'Plenty, Forestry , Ars Magica , Thermal Expansions , Railcarft and Metallurgy. But, the Vanilla Minecraft only has 8 ores.

The Ore Probability
This is a formula I invented to calculate the probability of obtaining metals and gems. It is [(Highest spawn height) - (Lowest spawn height)] x (Max cluster size) x (Max clusters per chunk)

In this case, Coal is 40946. And Diamond is 150.
