RPM, Inc. All drill and auger holes will be plugged with non - combustible material and sealed with grout or neat cement according to DRMS approved methods. At our meeting of December 16, 2011 with the DRMS we discussed the need to provide adit and shaft plug designs and bonding as part of the amendment application currently under review by the DRMS. We provided what ground water data we currently have, discussed the surface water standards we need to meet according to our CDPES discharge permit, and discussed the level of risk to the State and the environment if the design and bond for plugs were delayed to the next permit revision. If Calais were to cease to exist, the current site conditions would continue under the current permit approval. As we stated, Calais Resources Colorado is not adverse to plugs based on further evaluation by the Division. We also stated the present permit amendment under review by the DRMS, once it is approved and bond posted will provide for IMP standard adit and vent closures, not currently bonded for or designs provided for in the existing permit. At the December 16 meeting, it was agreed to allow Calais to provide plug design and bonding under the next permit revision which will include, among other things, underground crushing, milling and paste backfill of the tails. No waste rock or tails will be placed into workings with the approval of the current amendment. 6.3.5 Exhibit E — Map 18. The Reclamation Plan Map contains labels which show that both of the shafts, the Idaho Tunnel Portal, and the Cross Mine Portal will be "CLOSED ". However, the new Cross Mine Decline Portal does not contain this label. In order to maintain consistency between the Reclamation Plan and the Reclamation Plan Map, Please revise the Reclamation Plan Map to show the Cross Mine Decline Portal will be reclaimed and permanently closed. We have revised the Reclamation Plan Map as requested. However, please note the proposed closures are typical of the Inactive Mines Program closures and are not intended to be "Permanently" closure type structures as a hydraulic plug would typically be. A closure may result from a drop in commodity prices and the mine could close for a period of time. As long as a resource remains, the operation could return if commodity prices allow. 6.3.6 Exhibit F — List of Other Permits and Licenses Required: 19. Please state whether a permit from Boulder County will be required to install the septic systems and commit to providing the Division with copies of the approval(s). Yes, approvals are required from Boulder County. Calais commits to providing the DRMS with copies of the approvals. RPM.
