This 56-page PDF provides information about financial assurance for mine reclamation and closure. The topics covered include mine reclamation and liability; closure and financial assurance; and a state by state analysis of existing mines and estimated liability. Tables in the appendix list disturbed acreage, mine ownership, commodities extracted and existing total financial assurance amounts. The report includes four case studies; Coloradoï¿½s Summitville mine, Montanaï¿½s Zortman-Landusky mine, Nevadaï¿½s gold mining bankruptcy, and New Mexicoï¿½s Molycorp mine. The authors conclude that regulations should be strengthened and enforced to protect the public from huge shortfalls in surety bonds that would cover any reclamation issues.
