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.

The initial phase of gold mining relied heavily on simple, manual tools. During the Gold Rush era in the mid-19th century, prospectors used pans and sluice boxes to sift through riverbeds and stream sediments. The pan, a simple yet effective tool, allowed miners to separate gold from other sediments using water, a technique known as panning.
