COLORADO Division of Reclamation, Mining and Safety Department of Natural Resources 1313 Sherman Street, Room 215 Denver, CO 80203 January 22, 2015 Dean Misantoni P.O. Box 19 Alma, CO 80420 RE: Notice of Intent to Conduct Prospecting Application; Hock Hocking Mine; File No. P- 2014 -019; Second Notice of Deficiencies Dear Mr. Misantoni, The Division has identified several other comments and questions that must be addressed prior to the Division's decision due date. Please be advised that if you are unable to satisfactorily address any concerns identified in this review before the decision date, it will be your responsibility to request an extension of the review period. If there are outstanding issues that have not been adequately addressed prior to the end of the review period, and no extension has been requested, the Division may deny this application. 1. The Applicant has stated that water at the portal will be sampled during the half way through the project. Please specify if additional sampling will be conducted prior to or after the drilling program is complete or otherwise explain how collecting samples before the project is over will demonstrate that the quality of the water has not been impacted by drilling. The Division believes additional sampling events will be necessary to demonstrate the prospecting project did not have a negative impact on water quality. Water samples should be collected prior to, during, and after the drilling program. 2. The Applicant has committed to sampling the water discharging from the Hock Hocking portal. However, the Applicant has not explained how the proposed sampling program will ensure the prospecting operation is in compliance with applicable water quality laws and regulations. Water quality data from 1993, 1997, 2006 and 2014 have been submitted. However, at no point has the standard five quarters of sampling been conducted to establish a baseline for the quality of the water discharging from the mine. In addition, it does not appear the same locations have been sampled during each sampling event. The Applicant has stated the water discharging from the Hock Hocking mine will be sampled approximately half way through the project. Please explain how the water quality data from the proposed sampling will be used to demonstrate the mine water has not been impacted by the prospecting project. How will the results of the water sampling event be compared to the past water quality data? �pF • Cp��.
