Estimated Reading Time: 4 mins

Finding Deposits. The first step is discovering where gold deposits may be. Geologists use special Analysis of Promising Areas. Once some promising areas are identified through their geological Drill Testing/Samples. Next, rock samples are taken through drill testing and analyzed. Geologists Type of mine. If its determined the amount and quality of deposits makes mining worthwhile, Building Infrastructure. Before any mining can take place, infrastructure like roads and processing Mining samples and determining processing. Once mining gets underway, samples must be taken Processing on site Once ore is extracted, processing it into pure gold must be done. Ore is first Refining off site Once basic processing is done, the ore is taken to a refinery where the remaining Mine reclamation. After a few years, gold reserves in the mine will be exhausted.
