Minecraft Netherite Finder — Ancient Debris Y Level & Where to Find It (Java + Bedrock)
Quick answer: Ancient debris (the source of netherite) peaks at Y 15 and generates between Y 8 and Y 119, densest from Y 8 to 24. This Netherite Finder marks ancient debris from your seed on a visual map at 91% accuracy on Java 26.2 and 71% on Bedrock 1.26.30.
What Y level is ancient debris / netherite?
Ancient debris is most common at Y 15. It generates throughout the Nether from Y 8 up to Y 119, but the dense band is Y 8 to 24 — so the netherite level players mine at is Y 15 (sometimes Y 14–16 to clear a 2-block-tall tunnel). Netherite itself is crafted from the scrap you smelt from ancient debris.
Where does ancient debris spawn?
Ancient debris spawns anywhere in the Nether, buried inside netherrack, basalt and blackstone — it is never exposed to air, so you have to dig or blast to it. It is blast-resistant, so bed or TNT mining at Y 15 is a common tactic. The finder marks the chunks most likely to hold a vein so you don't blast blind.
Best Y level for netherite in Bedrock?
Bedrock uses the same Y 8 to 24 dense band and Y 15 sweet spot as Java. The finder supports Bedrock 1.26.30; toggle the edition and the accuracy badge updates to the Bedrock figure (71%, a conservative floor).
Best Y level & finder accuracy
| Ore | Best Y level | Spawn range | Java accuracy | Bedrock accuracy |
|---|---|---|---|---|
| Netherite | Y 15 | Y 8 to 119 | 91% | 71% |
Accuracy is the share of marked hotspots that really contain the ore in your world, shown as a plain number.
How the ore finder works
- Enter your world seed and pick your edition (Java or Bedrock) and version — the map redraws your exact world.
- Pick an ore from the rail above the map — its hotspots appear automatically on your world, with no button to press.
- Pan or zoom and fresh hotspots keep spawning. Click any one for its exact X / Y / Z, then dig there — the accuracy badge shows how often a marked spot really holds the ore.

How does the Minecraft Ore Finder work?
The Ore Finder reproduces Minecraft's own ore-placement maths from your world seed, entirely in your browser. It runs the same ore-distribution and cave-carving steps the game uses, then marks the chunks where diamonds, netherite and other ores are most likely to be exposed. Nothing is uploaded – your seed never leaves your device.
Why isn't the Ore Finder 100% accurate?
Where an ore ends up depends on the exact terrain and caves Minecraft carves around it, and no in-browser tool can rebuild every block the game places. We reproduce that terrain very closely, so a hotspot marked with a high percentage really contains the ore in your world around 85–91% of the time. A few spots may have been carved away by a cave or shifted slightly, so treat the markers as very strong leads rather than a guarantee.
Which ores can the finder locate?
In the Overworld it finds diamond, iron, copper, gold, redstone, lapis lazuli and coal, and in the Nether it finds ancient debris (netherite). You search one ore at a time and can optionally limit the search to a specific Y level.
What is the best Y level to mine diamonds?
Diamonds get more common the deeper you dig, peaking around Y -59 in current versions (they generate between Y -64 and Y 16). The finder defaults to each ore's full spawn range, and you can tick 'limit to a specific Y level' to focus on the richest band – for diamonds, around Y -59 to -54.
Does the Ore Finder work for my Minecraft version?
It works on both Java and Bedrock Edition. On Java it covers modern versions, including 1.21 and the 26.x releases, which share the same ore-generation rules. Bedrock Edition is now supported as well – on 1.18 and newer it finds the Overworld ores (diamond, iron, copper, gold, redstone and lapis lazuli). The two editions use different world generators, so make sure you pick the edition your world was created in.
Is using the Ore Finder cheating?
That is up to how you like to play. In single-player it is just a faster version of strip-mining for a diamond start. On multiplayer servers, check the rules first – some servers don't allow seed-based tools.
