Australian researchers have identified a matrix of risks including environmental, social or governance that could impede future copper discoveries.Environmental impact of mining Wikipedia,Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.Copper risk matrix highlights challenges MiningNews.net,"We found that low copper grades was the sole challenge in only three or four per cent of the undeveloped orebodies we analysed," he said. Other risks could be overcome by investing in seawater desalination plants, using dry stack tailings dams and other approaches to reduce the external impacts of mining
