A gold ore grade measures the concentration of gold in the ore extracted from a mine. It is typically expressed in grams per tonne (g/t) or ounces per ton (oz/t). Higher grades mean more gold is present in the ore, making it more valuable.

The resulting gold-bearing quartz veins are emplaced over a unique depth range for hydrothermal ore deposits, with gold deposition from 15-20 km to the near surface environment. On the basis of this broad depth range of formation, the term 'mesothermal' is not applicable to this deposit types as a whole. ... Orogenic gold deposits: a proposed ...
