collected from the VLF. Results indicate that the bulk of the total dissolved solids in solution <br />consist of metallic cations and simple anions. To the best of CC&V's knowledge none of the <br />likely/indicated compounds have strong odors. <br />3) Estimated daily volume of solution emitted through the sprinklers/snow-making machines, —3.6M <br />gallons per day is being pumped through the sprinklers/ evaporators. The bulk of the flow through the <br />sprinklers/evaporators falls back onto the pad. The exact amount of evaporation is difficult to measure <br />because it is dependent on changing weather conditions. Reported values in the literature suggest losses in <br />similar circumstances are on the order of 5%. This agrees with bulk observations of recent solution flows. <br />4) Confirmation that the emitted solution is barren. The majority of the emitted solution is barren. <br />Enrichment solution is also emitted in some areas of the pad. Both solutions are chemically similar and <br />have the same nominal cyanide concentrations. The only difference is that enrichment solution bypasses <br />the recovery plant before being returned to the pad and therefore has a higher gold concentration. <br />The wetted area around the wobblers has been monitored and does not extend off the VLF. <br />There is no analytical proof that what people have smelled is Cyanide as we have not received any <br />description of the odor and/or times when the issue occurred. Without knowing the specific time, <br />location and date of the complaint, it is really difficult for CC&V respond more fully to this <br />inquiry. <br />The use of wobblers / sprinklers as an alternative to drip lines on the VLF is discussed in the <br />MLE-2 Amendment 10 Project Description. <br />Solution typically will be applied using drip irrigation; however, there may be periods <br />when sprinkler -type wobblers will be used to apply solution to the ore. (Project <br />Description 2012: Volume 1, 7-13). <br />CC&V has used similar solution management strategies in the past without any indication of <br />offsite odor. <br />Please contact me at (719)-689-4048 should you have questions or wish to discuss this response <br />to DRMS's Corrective Action. <br />Sin erely yours, <br />Chris Hanks <br />Chief Environmental Coordinator <br />cc: Jonathan Gorman <br />Enclosure <br />
