Most guides rank Pals by Mining Lv and stop there. In practice, you choose a miner per resource: the cheapest Pal that clears the node first, then the optimum you switch to once you can field an S/A-tier roster. The table below cascades both — early pick (works on day one) and the optimum once you've unlocked higher tiers.
Stone. Used for almost every base structure recipe. Any Lv 1+ Pal works; speed-up only matters past the first 5 hours.
Iron Ore. The first ore that gates progression — needed for ingots, pickaxe upgrades, and most weapons. Skip B-tier and breed straight to Digtoise if you can.
Coal. Needed for refined ingots + gunpowder. The full where-to-mine breakdown lives in the coal guide.
Sulfur. Used for gunpowder + tech-tier explosives. Sulfur nodes cluster in volcanic biomes — pair the miner with a heat-tolerant teammate.
Pure Quartz. Circuit-board input for late-tech weapons. Where-to-mine coverage in the Pure Quartz guide.
Hexolite. Feybreak-update ore. Nodes cluster in Astral Mountains caves; community testing puts node tier at Mining Lv 3 minimum. DLC-gated.
Pal Metal Ore. The endgame gate. If you can't field one of these, your Pal Metal Mine structure stalls and you can't craft the late-tech weapon tier.
