Timberlake, Cave: All that glitters may not be gold Read more here: http://www.thestate.com/2013/08/25/2937357/timberlake-cave-all-that-glitters.html#storylink=cpy

Given the severe and long-lasting negative impact of gold mining, particular attention should be paid to providing sufficient financial assurances to protect the community. Reclamation and closure for gold mines can cost more than $100 million, yet the bonding set by the state reportedly has been estimated at only $20 million.
In addition to requiring sufficient financial assurances, it is also common for states to collect a small percentage on every ounce of gold mined. Proceeds could be directed to the communities most affected by mining operations and other worthy water-restoration efforts.
