Overmining refers to the excessive extraction of Natural Resources, such as minerals or fossil fuels, beyond sustainable levels. This practice can lead to significant environmental degradation, including habitat destruction, soil erosion, and pollution, as well as economic issues like resource depletion. Overmining often occurs when short-term profits are prioritized over long-term ecological and community health. Sustainable mining practices aim to balance resource extraction with environmental and social considerations to mitigate these negative impacts.

Gold mining primarily involves several methods, with the most common being placer mining, hard rock mining, and by-product mining. Placer mining extracts gold from alluvial deposits in riverbeds or stream beds using techniques like panning, sluicing, and dredging. Hard rock mining involves extracting gold from ore deposits in solid rock, often using underground or open-pit methods. Additionally, by-product mining involves recovering gold as a secondary product from the extraction of other metals.
Overhand cut and fill mining involves excavating a horizontal slice of an orebody, then filling the void with a backfill material - typically mine waste or rejects from the processing plant . After backfilling, another slide is taken on top of the previous one, with the process proceeding until the orebody extraction is complete. Underhand cut and fill mining also starts with a single horizontal slice, but subsequent slices are removed from below the initial one. In underhand mining, the backfill material usually has cement added to make a low grade concrete roof that is sufficiently strong to safely work under.
