Gold Mining Operation: 10-30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.
