MOLLIE KATHLEEN TOURIST MINE C. The Division received comments from Dewey-Dwight&Associates on March 15, 2016 outlining concerns related to CC&V's proposed underground mine plan and potential safety impacts to the Mollie Kathleen tourist mine: • Please summarize the discussions CC&V(Newmont)has had with Dewey-Dwight& Associates/Mollie Kathleen Tourist mine regarding their stated concerns over"airflow, ventilation and subsurface ground stability"and CC&V's plans to monitor underground blasting to eliminate to the extent practical impacts to the Mollie Kathleen Tourist mine. RESPONSE. Newmont has had several discussions with Dewey-Dwight regarding its concern over airflow and potential impacts to the Mollie Kathleen tourist mine. Based on information gathered to date, the underground workings proposed to be developed per this Amendment 11 are not connected to the Mollie Kathleen. In addition, blast studies done by Matheson Mining Consultants, Inc. states that, "Proposed underground mining activity is not expected to contribute to an increase in ground motion over what is already expected with current surface mining activities. The charge weights per delay period in surface blasting are of larger size than typical underground blasting. The energy released in surface blasting creates surface waves that radiate concentrically from the energy source. Underground blasting typically results in lower surface wave amplitudes as the underground blast attenuates significantly before the wave train arrives at the surface. Newmont has had several meetings with Dewey-Dwight&Associates, most recently on September 6, 2016 and believes the outstanding issues with the proposed Amendment 11 activities have been resolved. Newmont will continue to communicate with Dewey- Dwight on a routine basis to ensure potential issues are addressed. • Based on the anecdotal narrative indicating the historical ability of"knowledgeable miners"(5th paragraph, second page)being able to travel underground from Cripple Creek to Victor by"traversing multiple underground workings" combined with the stated concerns about ventilation impacts from "Providence"blasting,the Division is concerned that the proposed backfilling of the North Cresson mine area(reference AM- II Drawing C-6)may impact air flow to the Mollie Kathleen as existing underground workings are plugged with the proposed pit backfill. Please commit working with the Molly Kathleen operators and to monitoring and investigating underground workings in the North Cresson mine that might be critical ventilation in the Molly Kathleen. RESPONSE: See response above. Newmont is not aware of a connection between the proposed Amendment 11 underground workings. Based on recent meetings, Newmont believes the issues raised by Dewey-Dwight&Associates in its letter to DRMS have been addressed. TELLER COUNTY D. The Division received comments from Teller County Community Development Services on March 4, 2016 outlining County requirements for changing the Cripple Creek Mining Overlay District(CCMOD). With the exception of"Septic Vault Permit#T-5839, ADR/Lab", Exhibit M(Vol. I) indicates all Teller County permits are current. Pursuant to Rule 6.4.13,please explain this apparent discrepancy and what is being done with Teller County to address their comments. Page 3 of 14
