Metallic Deposits CliffsNotes Study Guides

Metallic Deposits. Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined. Again, the profit line is dependent on a number of economic factors.

Geology: What is a Mineral Deposit? — Mining Focus

An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock.
