Cripple Creek & Victor Gold Mining Company <br />Cresson Project <br />Quality Assurance Monitoring and Test Results <br />Phase 46/C Triangle Liner Certification <br />August 10, 2010 <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 May 6 through May 15, 2010 for the certification of the liner system at the Phase <br />413/4C Triangle. The general location for the liner system certification 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 413/4C Triangle area lined to provide additional solution <br />containment for the VLF. <br />1.2 Construction Quality Assurance/Quality Control <br />AMEC provided CQA monitoring and testing services, and prepared this report describing the <br />monitoring and test results for the liner system certification. Figures and supporting CQA <br />monitoring and testing documentation are presented in appendices attached to this report. <br />1.2.1 CQA Monitoring of Earthworks <br />AMEC provided CQA testing and monitoring of earthworks for the Phase 413/4C Triangle liner <br />system certification. CQA testing and monitoring of earthworks was provided for in-place <br />materials in accordance with the AMEC Earthworks CQA Plan. The earthworks material <br />specifications for this project are summarized in Table 1. CQC earthworks testing was provided <br />to support the contractor during the manufacture of materials (DCF and SLF) and prior to <br />material placement. <br />&\PROJECTS\1125E C:CV CQA\H2 - DESIGN\TRIANGLE\FINAL\TRIANGLE CERTIFICATION REPORT FINAL REVI.DOC I
