      There is a growing awareness to the environmental threats posed by the abandoned mines that are scattered in the country today. As most of these mines were developed long before the enactment of the Philippine Mining Act and current environmental legislations, casual efforts were only initiated, if any, by the operators before they totally abandoned the area. Without appropriate management interventions, these mines were left to pollute vital waterways, such as heavy metals released from underground and surface mine workings, acid mine drainage from the reaction of exposed pyrites and sulphide materials present in the natural environment, and siltation due to exposed mine-out areas, among other environmental problems. Unrestricted access to degraded mine structures nearing collapse and neglected tailings ponds also remain constant risk to nearby communities.
