3 · Gold ore can generate in the Overworld in the form of ore features. Gold ore attempts to generate in two batches. The first batch generates 4 times per chunk in blobs of 0—13 blocks, from levels -64 to 32. It is most likely to be found around layer -16, becoming less common toward either end of the range.
