Hytale Thorium Ore Location Guide: Best Zone, Depth & Mining Route

Where to find Thorium in Hytale using game-file worldgen data. Learn the best zone, cave depth hints, and desert biome pass ranges for faster Thorium farming.

Thorium Quick Summary

Best Farm Route

Thorium is the ore that marks your arrival in Zone 2. It doesn’t show up anywhere else in Orbis — the Howling Sands are where this resource lives, and the worldgen is specific about where in that zone it concentrates.

The key detail: desert caves at Y 140-200 carry a biome-specific bonus pass that makes them significantly more productive than blind cave exploration. Target those first, and the rest follows.

Data here is pulled from Hytale’s game asset files. For the full ore table, use the Ore Locations Finder. For other resource guides, see the Resource Locations hub.

Thorium is a Zone 2-exclusive ore.

  • Region: Howling Sands (Zone 2)
  • Source: Cave systems
  • Best target: Desert cave terrain, Y 140-200
  • Default veins: Also present with a broader cave vein placement (vein column height 25-120)

Hytale Thorium Ore block

Two Thorium placement signals exist in Zone 2’s worldgen config:

  1. Default Zone 2 cave veins

    • Region: Howling Sands
    • Source: Cave
    • Detail: Default veins (vein column height 25-120)
  2. Zone 2 Desert biome cave pass

    • Region: Howling Sands
    • Biome: Desert
    • Source: Cave
    • Height range: Y 140-200

The desert biome pass is why targeted routes work better than random Zone 2 cave exploration. You’re not just hoping for default veins — you’re stacking a second, concentrated Thorium source on top of the baseline.

  1. Enter Zone 2 (Howling Sands) and find large desert cave networks
  2. Stay in Desert biome terrain and operate around Y 140-200
  3. Keep exploring side tunnels and branches even when you drop below the target band — default veins don’t stop at Y 140
  4. Cover connected cave systems before moving to a new entrance; Thorium rewards route density over sprinting between locations

It captures both placement signals at once:

  • The Desert biome pass gives you a concentrated window (Y 140-200)
  • The default cave veins fill in everything below

Locking yourself to one depth without sweeping the broader cave system leaves Thorium on the table.

Zone 2 cave runs will also produce:

  • Iron — everywhere, always useful
  • Copper — common, often incidental while routing for Thorium
  • Gold — narrower Y 102-110 cave band; worth targeting on the same run if your route allows it

If Thorium is your primary goal, anchor in deep desert cave systems and collect Iron/Copper opportunistically. For Gold, see the Gold Ore Location Guide to understand how its cave band fits within a Zone 2 run.

The game files include multiple Thorium block variants for different surrounding stone/material contexts. If you’re unsure whether a block is Thorium, open the Ore Locations Finder and search for Thorium to review all variants and their textures.

  • Mining in the wrong zone: Thorium is Zone 2 only — don’t waste time looking elsewhere
  • Surface wandering: Thorium is a cave ore; you need to go underground
  • Ignoring terrain type: Desert cave sections trigger the biome pass; non-desert caves only have default veins
  • Over-committing to Y 140-200: The default veins extend from Y 25-120 — a dry cave stretch above 140 doesn’t mean the whole system is barren

In Zone 2 (Howling Sands) — cave placements including a Desert biome pass at Y 140-200, confirmed from game asset files.

What is the best level for Thorium in Hytale?

Section titled “What is the best level for Thorium in Hytale?”

Start around Y 140-200 in Zone 2 desert caves for the biome pass concentration. Default veins also run at Y 25-120, so keep exploring connected branches outside the target window.

No — Thorium is a Howling Sands resource in the worldgen data. It doesn’t appear in other zones.

Yes. Both extracted Thorium placements are cave-based. Surface exploration won’t cut it.
