INTRODUCTION NewFields Mining Design and Technical Services (NewFields) was commissioned by the Cripple Creek & Victor Gold Mining Company (CC&V), which is owned and managed by Newmont Mining Corporation, to provide Construction Quality Assurance and Quality Control (QA/QC) for the construction of the Squaw Gulch Valley Leach Facility (VLF) Phase 1 Completion. The project is located in Teller County, Colorado, just east of the city of Cripple Creek. The Squaw Gulch VLF is included in the Cresson Project, which is a gold mining and ore processing facility comprised of surface mines, crushers, lined VLFs, gold recovery plants, and associated infrastructure. The Cresson project was designed and constructed to meet or exceed the requirements established by C.R.S. §34 32 101 et seq. and regulations promulgated there under by the Mined Land Reclamation Board (MLRB). The work associated with the Cresson Project is being performed under specific criteria established in Amendment No. 10 of Permit Number M‐1980‐244, as approved by the MLRB. This report documents the Construction Quality Assurance (CQA) and Construction Quality Control (CQC) services for the Squaw Gulch VLF Phase 1 Completion, and is a continuation of the “Squaw Gulch VLF Phase 1 (9,550‐foot Elevation Bench to Completed Areas Outlined on Figure 2,” submitted January 2016 by Amec Foster Wheeler (Amec). The attached Figures 1 and 2 present the general site location and the Squaw Gulch VLF Phase 1 Completion certification limits, respectively. 1.1. Project Description The Squaw Gulch VLF is located north of the current Arequa VLF in an area referred to as Squaw Gulch, and is referred to as the Squaw Gulch VLF as part of the Mine Life Extension 2 Project. This area encompasses Squaw, Anaconda, and Swede Gulches. The Squaw Gulch VLF Phase 1 Completion area is a continuation of construction, and includes the addition of approximately 63 acres required to complete the Squaw Gulch VLF Phase 1 construction. Construction associated with this certification report was completed in October 2016. The Squaw Gulch VLF Phase 1 Completion area was constructed by placing Soil Liner Fill (SLF), overlain with an 80 mil Linear Low Density Polyethylene (LLDPE) double sided micro‐spike (DSMS) geomembrane, and covered with Drain Cover Fill (DCF). The Phase 1 grading plan and typical VLF cross sections are shown on Drawings A200 and A220/A230 in the Issued for Construction (IFC) drawing set, respectively.
