Copper and iron pass through two different forms: an ore you gather and an ingot you process. Recipes for tools and benches commonly ask for the ingot, so carrying an ore stack does not yet satisfy that ingredient.

The Devastated Lands contains Cinder Wastes and Charred Woodlands. They are distinct region records, with their own generated-resource lists and creature associations. The release files also reference copper- and iron-bearing stone in sewer-generation masks in both regions.

The Emerald Wilds contains the named regions Seedling Woods and The Fens. Both are linked to copper- and iron-bearing stone in the release records. Their creature lists differ, making the region name more useful than searching only for “Zone 1”.
