NEWMONT <br />GOLDCORP <br />1 INTRODUCTION <br />This updated mining plan presents the changes to the Cresson Project mining operations under <br />this Amendment 13. The mining plan also provides the following: <br />1. a description of the affected lands boundary; <br />2. a description of the areas specifically affected by this Amendment 13, <br />3. the nature and sequence of mining activities including a generalized schedule and <br />sequence for the proposed operations, and <br />4. a description of the facilities developed at the mine site. <br />This mine plan was prepared in accordance with the Colorado Department of Reclamation Mining <br />and Safety (DRMS) requirements: specifically, Rule 6.4.4 of the Mineral Rules and Regulations <br />of the Colorado Mined Land Reclamation Board for Hard Rock, Metal, and Designated Mining <br />Operations. <br />1.1 Overview of Amendment 13 Activities <br />The following modifications are being implemented under this amendment: <br />1. Modification to backfilling sequence for Schist Island Mine Area due to construction of <br />Phase 3 of the Valley Leach Facility 2 (VLF2); <br />2. Use of OSAs and other material for structural backfill in the Schist Island pit to prepare the <br />surface for construction of VLF2 Phase 3; <br />3. Addition of run of mine (ROM) material handling and direct haul to VLF2 after lime/cement <br />addition, and <br />4. Use of Overburden Storage Areas (OSAs) as a resource. <br />It is proposed, under this amendment, to modify the Schist Island mine area and Squaw Gulch <br />Overburden Storage Area (SGOSA) to accommodate expansion of VLF2. This expansion is <br />herein defined as VLF2 Phase 3. The expansion adds approximately 8 million square feet (184 <br />acres) of lined area to VLF2 and increases the ore capacity by approximately 118 million tons. <br />Construction details and sequencing are described in the Valley Leach Facility 2 Phase 3 Detailed <br />Design Report which is provided as Appendix 1 to this Amendment 13 permit application. <br />In general, mining will continue as approved in prior permitting actions. Portions of the Schist <br />Island mine area, once mined out, will be back filled with waste rock from pits, material from <br />existing OSAs, or spent leach material to prep the surface for construction of the VLF2 Phase 3 <br />liner system. The re -use of spent leach material that has been verified as containing less than 0.2 <br />milligrams per liter (mg/1) weak acid dissociable cyanide (WAD CN) was approved under <br />Amendment 8. <br />Cripple Creek & Victor Gold Mining Company Exhibit D <br />Cresson Project Amendment 13 <br />
