Box 191 Victor, CO 80860 www.newmont.com Re: Permit No. M-1980-244: Cripple Creek _& Victor Gold Mining_ Comnanv ("CC&V" ): Cresson Proiect; — Chicago Tunnel December 201_6 Inspection Response Rock Material Sampling and Anal Dear Ms. Eschberger, Within the December 2016 DRMS inspection report received 9`h March 2017, it was found that "The Operator has failed to follow the approved mining plan for this permit as revised by Technical Revision No. 3 (TR -3). The Division's conditional approval of TR -3 required geochemical analyses of material relocated from inside the adit to surface, as necessary to determine whether the material is toxic or acid forming. The Operator has removed mine development material from the adit and stockpiled it at the surface. However, the Division has no evidence the Operator has conducted geochemical analyses of such material." The inspection report required two corrective actions. The first, due 4.8117, is to sample rock material removed from the Chicago Tunnel adit which is to be sent to a laboratory for analyses of the material's toxic and acid producing capabilities. The second, due 717117, is to provide to the Division the laboratory results of such analyses, include a report summarizing the results, describing where the material will be moved to accordingly, and providing an estimated timeline for completion. The purpose of this correspondence is to demonstrate CC&V has completed the corrective actions by collecting rock material samples and conducting proper chemical analyses. CC&V believes this work demonstrates it is unlikely the rock material will adversely affect the environment.
