Block Reference
HP, spawn weight, loot drops, and efficiency for all ore blocks grouped by biome.
HP per Dollar (hp/$): HP you must break to earn $1 expected value.
Lower = more efficient.
Blocks within each biome are sorted by HP .
Blocks marked "Visible — no drop" exist in the mine but yield nothing when broken.
