Metal Leaching definition

Metal Leaching means the production of leachate under neutral or alkaline conditions, Seepage or drainage from underground workings, pits, ore piles, Waste Rock, tailings, and overburden that could lead to the release of metals to Groundwater and surface water during the life of the mine and after mine closure.
