Mining Efficiency Guide
Which ore gives the most cash per HP broken? Lower HP/$ = better return on mining effort.
HP per Dollar (hp/$) = total HP you must mine to earn $1 expected value.
This accounts for variable drop quantities (averaged). Best picks are sorted first within each biome.
Only blocks that naturally spawn and drop items are shown.
Best Ore per Biome — Summary
| Biome | Depth | Best Ore | HP/$ (avg) | HP/$ (best case) | Value (avg/block) |
|---|---|---|---|---|---|
| Clay | 0–2 |  Iron Ore | 14.3 | 10.0 | $14.0 |
| Stone | 2–5 |  Silver Ore | 21.4 | 15.0 | $140.0 |
| Ice | 5–8 | Silver Ore | 42.9 | 30.0 | $700.0 |
| Fire | 8–11 | Silver Ore | 85.7 | 60.0 | $3500.0 |
| Dark | 12 | Silver Ore | 171.4 | 120.0 | $175000.0 |
| Green | 13 | Silver Ore | 342.9 | 240.0 | $8750000.0 |
| Orange | 14 | Silver Ore | 685.7 | 480.0 | $437500000.0 |
| Purple | 15 | Silver Ore | 1371.4 | 960.0 | $21875000000.0 |
General strategy: Prioritize iron and emerald in clay, then progress to the
stone biome as quickly as possible. The dramatic HP scale increase between biomes means
you need enough damage before venturing deeper — but deeper ores pay proportionally more.
