Iron Ore
Radial biome-distance schematic from the Core. It shows distance bands, not a fixed compass map; outer biome sectors are seed-dependent.

Know what to farm.
And where to go.
Core Keeper farming uses biome-specific ore, crop plots, fishing and enemy drops. The Core’s surrounding rings gate outward exploration, and defeating early Titans removes the Great Wall. Ore boulders become an automated mining target after drill access, while settled farms sustain food and buffs.

Iron is available before the Great Wall
Explore Clay Caves and Forgotten Ruins in the inner ring for Iron; the Great Wall gates outer biomes, not this early ore route.
Sources & fact checks
Find boulders before planning drill output
Ore boulders require Drills powered by an Electricity Generator or Lever. They keep working even when you travel elsewhere, so mark their locations for later collection.
Sources & fact checks
Clay Caves are an inner-ring route
Clay Caves sit next to the Undergrounds and contain Tin and Gold deposits. The Larva Hive is a sub-biome hazard, not a prerequisite for entering the caves.
