• followed by an application of one pore volume of H2O2 treated water. The rinsing is <br />followed by a period of water sampling to determine whether the water quality is <br />acceptable. The objective is to achieve an average of less than 0.2 mg/l CNWAD in the <br />rinsate. Based on CC&V's experience and reviewing other facilities, it is believed <br />detoxification can be properly achieved using two pore volumes of water and that the one <br />pore volume of H2O2 treated water will be unnecessary; however, the financial warranty <br />continues to contain all three pore volumes as CC&V has not made a presentation to <br />OMLR for an alternative. Current CC&V operating costs (2008) have been used to <br />establish water handling costs in this estimate. <br />12.8 Summary <br />Financial warranty requirements for reclamation of the Cresson Project, inclusive of <br />MLE disturbances, at full implementation have been determined. The total financial <br />warranty is estimated to be approximately $97.5 million for life-of-mine activities. The <br />overall costs will be incrementally posted as disturbances occur. <br />• <br />• Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />12-6
