Iron ore can generate down to Y-level -64, but it becomes slightly less common the deeper you go. However, the absolute peak efficiency is found at the very bottom of this range, specifically at Y-level -59 and -60.
Optimal Mining Levels for Cave Iron Efficiency
This approach exposes the maximum amount of stone blocks, increasing the chances of encountering iron ore veins. This involves digging a main horizontal tunnel at Y-59, then creating perpendicular branches every two blocks.
Within this range, iron ore is abundant and forms large clusters. By pressing the F3 key (or Fn + F3 on Mac), the Y-coordinate is displayed prominently at the top of the screen.
Cave Iron Mining Strategy at Y-Level -59 for Maximum Efficiency
