Newmont Mining Corporation <br /> Record of Construction Report <br /> VLF2 Recertification Project <br /> Drain Cover Fill 9650'—9750'Elevations <br /> NewFields Project No.475.0106.026 <br /> July 11,2018 <br /> Mine operation delivered material from the designated stockpile to the VLF2 Recertification area <br /> traveling on no less than 20 feet of geomembrane cover, placing the material in a temporary <br /> stockpile near the recertification area. The DCF was pushed and placed in a two-foot lift on <br /> approved geomembrane by Low Ground Pressure (LGP) CAT dozers fitted with calibrated Global <br /> Position Systems (GPS) Sensors. All DCF was placed in an uphill direction on slopes steeper than <br /> 4H:1V using the Soil Liner Fill (SLF) as-built survey raised two feet as a reference for DCF finish <br /> grade, maintaining a minimum of two-feet of geomembrane cover. The final DCF surface was <br /> surveyed and compared to the SLF as-built presented in the VLF2 Recertification Project Record <br /> ' of Construction Report for Subgrade and Geomembrane 9650'-9750' Elevations. The DCF depth <br /> was verified to be at least two-feet in depth. The DCF final and isopach contours are shown on <br /> Record of Construction Drawing 1 presented in Appendix A. <br /> 1.1 As-Built Survey <br /> ' Foresight West provided as-built survey to NewFields used for the generation of VLF2 <br /> Recertification Project DCF between the 9650' and 9750' elevations Record of Construction <br /> Drawing. A copy of the Surveyor's Professional License is presented in Appendix B. <br /> ' 2.0 DRAIN COVER FILL QUALITY ASSURANCE <br /> ' NewFields representatives were present during all DCF placement activities to verify that the DCF <br /> was placed in accordance with the Technical Specifications and that no damage to the <br /> geomembrane occurred. If any damage to the geomembrane was noted, work activities were <br /> ' paused and the damage was repaired prior to resuming DCF placement. <br /> ' The VLF2 Recertification for DCF between the 9650' and 9750' elevations was constructed by <br /> placing approximately 5,735 cy of DCF. The particle size distribution and atterberg limits testing <br /> frequencies were one sample for every 20,000 cy. One DCF sample was tested with passing <br /> results for the VLF2 Recertification for DCF between the 9650' and 9750' elevations. DCF <br /> laboratory testing results are presented in Appendix C. <br /> ' 2.1 Daily Observation Reports <br /> Field daily observation reports prepared by NewFields during the VLF2 Recertification Project <br /> DCF between the 9650' and 9750' elevations are presented in Appendix D. <br /> Page 2 <br />
