Identify the Clay Caves, gather a first tin haul, avoid searching stone for it, and choose between crafting and a boulder rig.
Item answer
Look for Tin Ore in the Clay Caves , especially deposits in the pinkish clay walls. Mine the wall deposits, confirm the item is Tin Ore, then smelt it in a Furnace.

#Direct Answer
Look for Tin Ore in the Clay Caves, especially deposits in the pinkish clay walls. Mine the wall deposits, confirm the item is Tin Ore, then smelt it in a Furnace. If your route has turned into blue-gray stone and keeps producing Iron Ore, you have found the Forgotten Ruins; change direction to find clay instead of expecting more time in the same stone tunnel to produce tin.
The Tin Ore reference and a community search discussion document why finding iron before tin does not establish that the world's tin is missing.
#Find Clay Before Looking For More Sparkles
Start from a known route near the Core and explore until dirt gives way to clay. Mark that transition. Search the clay area with several short branches that expose fresh walls, rather than extending one tunnel far into another biome. Return to the marked transition when deciding where to open the next branch.
Not every brown or orange-looking area is a good tin search route. Check a wall's item name after mining it and compare the terrain with the Clay Caves reference. Larva-heavy structures within the area can also have tougher walls and more danger than the ordinary clay you need for a first haul.
Take a repaired copper-stage pickaxe as a practical starting point. Tool name alone is not the whole mining calculation: total mining damage and the particular wall matter. If ordinary clay breaks but a special structure does not, search ordinary clay deposits rather than treating the structure as the entrance to all tin.
#A Repeatable First-Tin Search
- Store spare loot and leave room for ore. Bring food, torches, bridges, and a usable weapon.
- Enter the marked clay area and expose fresh wall edges.
- Mine sparkling deposits and check the resulting ore name.
- Mark a large tin boulder separately if you find one. Do not use the whole trip trying to break it with the pickaxe.
- Return, smelt Tin Ore in the Furnace, and reserve the bars needed for the Tin Workbench.
- Continue from a different marked branch if the first pocket is exhausted; do not recheck already cleared clay indefinitely.
If enemies consume most of the trip's food before you collect ore, establish a shorter safe return lane. More exploration distance is not useful if you repeatedly lose the haul on the way home.
#What The Tin Patch Changes
The official 1.3.0.1 announcement increased tin in the Clay Caves. This supports checking your installed version when comparing your world with an older search guide. It does not prove that already generated and explored clay in an older world has refilled.
World-generation settings and the portions already explored still matter. Search fresh clay and record what you actually uncover; do not delete an established world solely because someone else's new seed showed a richer pocket.
#Spend Tin Without Blocking The Next Workbench
| Your current situation | Useful first spending choice | Why |
|---|---|---|
| No Tin Workbench | Build that station | It opens the crafting chain instead of adding one isolated item |
| Ruins walls are the next obstacle | Improve your mining setup and keep repair materials | Iron is the next resource task |
| Repeated copper or tin shortages, boulder nearby | Consider a powered Crude Drill | Early boulder mining can work before scarlet-tier machines |
| Ghorm is the next fight | Keep a usable weapon and movement preparation | A fixed pile of traps is not a compulsory tin expense |
These priorities are editorial choices. Read the actual recipe counts at the station before allocating the whole haul. A release-era drill discussion also shows why one Crude Drill should not be expected to fill a chest immediately.
#FAQ
#Why did I find iron before tin?
Different branches can lead into stone before clay. That is a map outcome, not proof of a required boss or broken ore progression.
#Do I need to defeat Ghorm first?
No. You can mine ordinary clay deposits while Ghorm still patrols. Stay out of his path while working nearby.
#Should I drill the first tin boulder I find?
If you can power the machine and revisit safely, it can help recurring supply. For the first few bars needed immediately, ordinary wall deposits are usually the simpler task.
#Sources And Review Notes
The official announcement supports a specific tin-generation change; it is not a universal yield or old-world regeneration guarantee. Community ore and search references support biome identification and the player difficulty finding clay. Search branches and spending priorities were rewritten November 10, 2026 without a new seed survey.
