Set the depth the drill is mining at, where it stands, and the lenses you put in it. The table shows every ore it can produce and its chance per operation.
Lenses (up to 6)
How the drill picks an ore
Each ore has a list of depth ranges, dimensions and biomes, each with a weight; the drill uses the first entry that fits where it is and the depth it is set to. Every matching lens in its six lens slots adds 8 to that ore's weight, so the right colour of lens pulls a rare ore up quickly. The chance is the ore's weight divided by the total of everything the drill can make at that spot.
