<br />Cripple Creek & Victor Gold Mining Company Exhibit D Cresson Project Amendment 13 15 <br />TR-104 permitted remining of mineralized waste materials from OSAs. As part of Amendment 13, CC&V plans to process mineralized waste from OSAs where it is economical to do so. Mineralized waste material will be handled the same as ore and will be hauled to the crusher circuit, mixed with lime and hauled to VLFs for processing. Mineralized waste may also be managed as ROM and may be routed to the lime/cement silo prior to placement on VLFs, as approved in TR-114. <br />3.6 Sequence of Development – Underground Mining Areas <br />Underground mining was discussed and approved as part of the Amendment 11 permitting action. Additionally, underground exploration was detailed and approved as part of TR-116. No further changes to those approvals are made under this Amendment 13. <br />3.7 Overburden Management <br />Rock without recoverable gold, but which must be removed to access the gold-bearing ore, is called overburden. Overburden will be loaded from the active mine areas for transport and managed at the designated OSAs. Overburden will be managed in designated mine areas once mining operations have ceased and the area is opened for overburden. The overburden management practices and management facilities are described below. <br />3.7.1 Squaw Gulch Overburden Storage Area (SGOSA) <br />A portion of the existing SGOSA will be removed to make room for construction of VLF2 Phase 3. Overburden removed from SGOSA or other locations will be placed in the Schist Island mine area to reach the design grades required for VLF2 Phase 3 construction. Details of the overburden removal from SGOSA are described in the Valley Leach Facility 2 Phase 3 Detailed Design Report provided in Appendix 1 to this Amendment 13. <br />3.7.2 East Cresson Overburden Storage Area (ECOSA) <br />No modifications to ECOSA are planned under this amendment. ECOSA will continue to receive overburden material from the active mine areas. ECOSA will be built-out and graded according to sequencing described in previous amendments. <br />3.7.3 Deposition of Overburden into Mine Areas <br />General <br />As previously stated, this amendment modifies the Schist Island mine area backfill plan to accommodate backfill removed from the SGOSA or other areas for the construction of VLF2 Phase 3. <br />Except for the proposed changes to the Schist Island mine, as provided in this amendment, deposition of overburden into mine areas (i.e., mine area backfilling) will not change from that
