Gold ore is a rare mineral block found underground. Deepslate gold ore is a variant of gold ore that can generate in deepslate and tuff. Gold ore drops as raw gold if mined by an iron pickaxe or higher. If mined by any other tool, it drops nothing. Mining with a Silk Touch pickaxe drops itself. It is affected by Fortune enchantment, dropping 1–2, 1–3, or 1–4 raw gold respectively with ...
