If a Qi quest is in progress which makes the mine more dangerous, there is a small chance for a stone to be replaced with a radioactive ore. This is very dependent upon luck, with the luck boost from the special charm being worth 192 levels, and the worst luck requiring a depth of level 550 to have any chance ore will drop. This is also dependent on luck buffs, with each level of luck worth 15 floors. This will replace any of the below stones.

The chance for a stone to be a metal ore (copper, iron, gold or iridium) will vary depending on floor, starting at 2% on floor 1, rapidly increasing to 16% on floor 100, and then increasing to 100% on floor 1780. Luck has no affect on this chance, or on the ore distribution. Copper and iron have the same distribution. From floor 2010 only gold and irridium ore will be found, and from floor 5700 only irridium ore will be found from this generation.

If the stone is not a metal ore, there is a chance for it to be a a gem stone ore (diamond, emerald, aquamarine, ruby, amethyst, topaz and jade), a gem node (the round purple stone), a mystic stone or a dark grey rock. This means that the chance can decrease as you go deeper as more of the stone is metal ore, and above floor 1780 these will not be found.

Luck and mining level only play a signifcant role for mystic stones and gem nodes. For others the contribution is negligible.

For gem stone ores, diamond is slightly rarer than most, and jade is half as rare as most. The chance initially increases, peaking at a chance of ~0.35% (~0.18% for jade) at a depth of ~800, before dropping back down.

Dark grey rocks,  start with their maximum chance at level 1 (9.73% for dark grey rocks, 0.005% for mystic stones, 0.059% for gem nodes for best chances), and drop proportionally as ores take their place.
