Cripple Creek & Victor Gold Mining Company <br />Cresson Project ame <br />Quality Assurance Monitoring and Test Results <br />Liner Recertification <br />December 17, 2009 <br />1.0 INTRODUCTION <br />Cripple Creek & Victor Gold Mining Company (CC &V) operates the Cresson Project, located in <br />Teller County, Colorado, near the city of Victor. The Cresson Project is a mining and ore <br />processing and beneficiation facility that is composed of surface mines as well as a valley leach <br />facility (VLF); an adsorption, desorption, and recovery (ADR) plant; and associated <br />infrastructure, all of which were designed and constructed to meet or exceed the requirements <br />established by CRS §34 -32 -101 et seq. and regulations promulgated there under by the Mined <br />Land Reclamation Board (MLRB). <br />The work associated with the Cresson Project is being performed under specific criteria <br />established in Amendment Nos. 8 and 9 of Permit Number M- 1980 -244 (Permit), as approved <br />by the MLRB. This Report documents the Construction Quality Assurance (CQA) and <br />Construction Quality Control (CQC) services provided by AMEC Earth and Environmental <br />(AMEC) from October 12 through November 14, 2009 for the recertification of the liner system <br />at the Phase IVc VLF Load Out Bin (LOB) and the Phase IVa ramp. The general location for the <br />liner system recertification is presented on Figure 1. <br />1.1 Project Description <br />The existing Cresson Project was constructed in phases from 1994 through 2004 (Phases I <br />through IV). Phases I and II were permitted in 1994 and constructed during the 1994 through <br />1996 construction seasons. Phase III was permitted in 1999 and construction was initiated the <br />same year, with completion in 2000. Phase IV was permitted in 2000 and construction was <br />completed in 2004. Phase 5 was permitted in 2008 and is currently under construction. As part <br />of the construction activities, the Phase IVc LOB was moved from its current location to a new <br />pad located to the north end of the VLF. The Phase IVc LOB was certified in October 2004; <br />however a small section of the liner system (geomembrane and SLF), as identified in Figure 2 <br />included within Appendix A of this report, was left uncertified because the thickness of DCF was <br />considered insufficient for protection from haul truck traffic. With the relocation of the LOB, this <br />area was uncovered, inspected, relined, and recertified as part of this project. <br />In addition to the LOB, a portion of the haul road ramp in the Phase IVa, as identified in Figure 2 <br />included in Appendix A of this report, was recertified. This area was originally certified in August <br />2002, as part of the Phase IVa construction activities. A portion of the ramp was left uncertified <br />because the thickness of the DCF was considered insufficient for protection of the liner from <br />haul truck traffic. The uncertified area of the ramp was uncovered, inspected, and relined as part <br />of this project. A portion of the ramp was also reconstructed to re- establish grade in this part of <br />the VLF. <br />S: \PROJECTS \1125E CCV CQA \H2.
