Mineral deposit Britannica
Mineral deposit, aggregate of a mineral in an unusually high concentration.. About half of the known chemical elements possess some metallic properties. The term metal, however, is reserved for those chemical elements that possess two or more of the characteristic physical properties of metals (opacity, ductility, malleability, fusibility) and are also good conductors of heat and electricity.

Ore Wikipedia
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining they are then refined (often via smelting) to extract the valuable element or elements.
