Ores and construction
Iron Ore
Iron provides a useful early metal tier for workbench and equipment progression.
Caves across the world; Snow Caves are an optional route if one is convenient.
Repeat as needed for later crafting. Each cave trip yields a variable amount, so plan around recipes rather than assuming a fixed vein count.
Stop the run when your smelted bars cover the next planned workbench or equipment recipe; resume mining when another recipe requires Iron.
