Gold ore is a type of ore that can be obtained by mining gold ore rocks, requiring a Mining level of 40 or higher, and granting 65 experience. Gold ore can be smelted into gold bars through the Smithing skill, requiring level 40 Smithing. Gold bars can then be crafted to make various pieces of jewellery.
Gold ore is the raw material used to smelt a gold bar. Smelting gold ore into a bar gives 22.5 Smithing experience, or 56.2 with the goldsmith gauntlets equipped. Since smelting gold bars is an easy way to gain Smithing experience, gold ore is often sold at higher prices than the bars.
