NEWMONT <br /> GOLDCORR <br /> 4) Solution Application: Please discuss whether there is any difference in the leach <br /> solution being applied to the study cell and that used elsewhere on VLF 1 and 2, <br /> specifically whether there is a difference in cyanide concentration or any other <br /> designated chemicals. <br /> The solution that will be applied to the study cell will be the same solution <br /> utilized elsewhere on the Valley Leach Facilities (VLFs) 1 and 2; with no <br /> difference in cyanide concentration and no addition of any other designated <br /> chemicals. <br /> 5) Geotechnical Stability: The narrative on page 2 references a geotechnical memo <br /> in Attachment 1. Based on the information provided in the submittal, the DRMS is <br /> concerned with the potential for the liner to act as a slip plane (i.e., <br /> geomembrane(?) on a 10 percent slope, with solution present to potentially act <br /> as a lubricant, as well as a significant portion of the liner being above the frost <br /> depth) and what the ultimate disposition of the 36,000 tons of ore and crushed <br /> ore might be were it to slide down the 10 percent lubricated liner slip surface. <br /> Pursuant to Rule 6.5(2) and (3), please provide a slope stability analysis <br /> performed by a registered professional engineer in the State of Colorado <br /> addressing the aforementioned concerns, accounting for reduced friction on the <br /> wet liner surface. Please be aware depending on your response to Comment 6a <br /> below, the DRMS may also require seismic loading be considered in this <br /> analysis. Please ensure the slope stability analysis conforms to Mined Land <br /> Reclamation Board 30.0, available on our website: <br /> https://mining.state.co.us/Site CollectlonDocuments/MLRB%20Policies%20Revis <br /> ed%20May%202018.pdf. <br /> Slope stability analysis conforming to the Mined Land Reclamation Board 30.0 <br /> Factors of Safety for Slope Stab!lity/Geotechnical Analyses has been <br /> completed with a stamp and signature from a registered professional engineer <br /> in the State of Colorado; included in Attachment 1 of this response. <br /> 6) Implementation Schedule: The narrative on page 2 does not discuss the duration <br /> of this project, nor when reclamation will begin. Please provide the following: <br /> a. Expected duration of the test, <br /> b. Expected criteria for initiating reclamation and how long CC&V expects <br /> reclamation to take. <br />
