Copper is most common at Y 48 (biggest veins in dripstone caves). Enter your seed and this Copper Finder maps copper ore at 89% accuracy on Java 26.2 and 89% on Bedrock 1.26.40 — best Y level, spawn range and where to find copper, on a visual map.

Quick answer: Copper is most common at Y 48 and spawns from Y 112 down to Y −16, with the biggest veins in dripstone caves. This Copper Finder marks copper ore from your seed on a visual map at 89% accuracy on Java 26.2 and 89% on Bedrock 1.26.40.
| Edition | Version | Best Y level | Spawn range | Finder accuracy |
|---|---|---|---|---|
| Bedrock | 1.18 – 26.40 (current) | Y 48 | Y 112 to −16 | 89% |
| Java | 1.20.2 – 26.2 (current) | Y 48 | Y 112 to −16 | 89% |
Accuracy is the share of marked hotspots that really contain the ore in your world, shown as a plain number.
Copper ore generates from Y 112 down to Y −16, peaking around Y 48. Dripstone caves get much larger copper veins, so a dripstone cave near Y 48 is the fastest place to mine it. The finder marks the chunks most likely to hold a vein on a map of your world.
The best Y level for copper is Y 48 — the centre of its spawn range and where ordinary veins are densest. For the giant veins, look for dripstone caves around the same height and mine outward from Y 48 for the best yield.
Bedrock uses the same Y range and Y 48 sweet spot as Java. The finder supports Bedrock 1.26.40 at 89% accuracy — the badge by the page title shows both editions' figures.
Giant copper veins generate at Y 50 to 0, overlapping the Y 48 band where ordinary copper is densest — granite-filled formations many times the size of a normal copper blob, with blocks of raw copper inside. Both Java and Bedrock generate them from the same seed, and the full seed map draws them as their own layer. When you need copper by the shulker box rather than by the stack, that layer is the thing to aim at.

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.
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 on Java, and 70–93% on Bedrock — the per-ore figure for the edition you picked is on the badge and in the table above. 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.
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.
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.
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.
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.
