Mineshaft finder accuracyJava 98% · Bedrock 99%

Quick answer: Mineshafts generate underground throughout most Overworld biomes, full of rails, minecart chests and cave-spider spawners. This finder marks them at 98% accuracy on Java 1.13 and later, 99% on Java 1.12 and older, and 99% on Bedrock.

Where do Mineshafts generate?

Mineshafts generate underground across most Overworld biomes as sprawling wooden tunnel networks. In badlands they also generate higher up and partly exposed, with extra gold — the only place mineshafts reach near the surface.

How do I find a Mineshaft from a seed?

Enter your seed and the finder marks mineshaft locations. Open a marker for coordinates and dig down or follow caves to reach the tunnels. Watch for cobwebs around Cave Spider spawners as you explore.

What loot is inside a Mineshaft?

Minecarts with chests scattered along the rails hold loot such as diamonds, gold and iron, rails, name tags, lapis and enchanted books — and the structure itself is a free source of rails and wood for transport networks.

How accurate is the mineshaft finder?

Mineshaft markers read 99% on Bedrock and 98% on Java 1.13 and later. Java 1.12 and older generate mineshafts differently, so that older version range was measured separately and reads 99% — the map switches between the two figures by itself when you change the version, because we publish a number only for versions we have actually measured. Both Minecraft 26.3 (Java) and 1.26.51 (Bedrock) are supported.
