Cripple Creek&Victor Gold Mine <br /> Valley Leach Facility Expansions <br /> Detailed Design for Permitting 111 <br /> NewFields Project No.475.0106.064 <br /> • March 2024 <br /> drain towards the southwest, towards the existing VLF2 Phase 1/2 PSSA. Earthworks will be <br /> relatively minimal, as the proposed pad is generally located on compacted structural fill or <br /> bedrock. During operations, a haul road will be constructed from the southwest to the northeast <br /> portion of the pad, allowing for ore to be loaded on the VLF. <br /> 4.3.2. VLF2 Phase 4 Stage B <br /> Stage B of the VLF2 Phase 4 Expansion will increase the pad footprint to the east and will generally <br /> utilize existing ground contours to direct solution towards the VLF2 Phase 1/2 PSSA. Although <br /> most of the pad is located on bedrock or compacted structural fill, the eastern side of the pad <br /> follows Joe Dandy hill and will require areas of cut in order to obtain safe and constructable <br /> slopes. The Joe Dandy Hill is also anticipated to have several underground workings, which will <br /> be remediated following the guidelines in Section 2.3. <br /> During construction, Stage B will be phased to allow for ore loading in Stage A. <br /> 4.3.3. VLF1 Phase 6 Stage A <br /> Stage A of VLF1 Phase 6 contains the proposed VLF1 Phase 6 PSSA and is located over the existing <br /> crusher on the northeast side of VLF1. This area is generally located on bedrock or compacted <br /> structural fill. Prior to construction, the crusher, support building and miscellaneous <br /> infrastructure will be removed.The pad will be graded to drain towards the proposed VLF1 Phase <br /> 6 PSSA, which will require major earthworks in the form of a large embankment constructed for <br /> containment on the western side. The pad will primarily lay on bedrock or constructed fill. <br /> Solution will collect in the low point of the VLF1 Phase 6 PSSA, which is located to the south and <br /> at the eastern toe of the proposed embankment. The proposed VLF1 Phase 6 PSSA utilizes the <br /> existing VLF1 Phase 4 and VLF1 Phase 5 as its northern and southern boundaries, respectively, <br /> and will require geomembrane to be installed on the re-sloped sides of these facilities.The areas <br /> surrounding the construction of the PSSA may contain underground workings; these will be <br /> remediated according to the guidelines described in Section 2.3. <br /> 4.3.4. VLF1 Phase 6 Stage B <br /> VLF1 Phase 6 Stage B fully encapsulates the footprint of the Elkton Pit on Joe Dandy Hill, which is <br /> anticipated to be completely excavated before VLF construction begins. The pad will lay on <br /> primarily bedrock or compacted structural fill. Prior to construction CC&V will provide, place,and <br /> compact overburden material to backfill the Elkton Pit utilizing existing mining equipment, as <br /> currently being done at Schist Island Pit as a part of VLF2 Phase 3.
