DNR COLORADO <br /> CO Division of Reclamation, <br /> Mining and Safety <br /> Department of Natural Resources <br /> 1313 Sherman Street, Room 215 <br /> Denver, CO 80203 <br /> April 19, 2016 <br /> Mike Jones <br /> Teton Drilling, Inc. <br /> P.O. Box 550 <br /> Henderson, CO 80640 <br /> RE: Dixie Mine; DRMS File No. M-2015-028; Adequacy Review No. 4 <br /> Dear Mr. Jones, <br /> The Division has identified several other comments and questions that must be addressed prior to <br /> the Division's decision due date. Please be advised that if you are unable to satisfactorily <br /> address any concerns identified in this review before the decision date, it will be your <br /> responsibility to request an extension of the review period. If there are outstanding issues <br /> that have not been adequately addressed prior to the end of the review period, and no <br /> extension has been requested, the Division will deny this application. <br /> 1. The Applicant has revised the Mining Plan and will no longer set up a mobile mill on site. <br /> The Applicant has stated the ore will be taken to the Federal Mill for processing. Therefore, <br /> the Division will not bond for reclamation of disturbance associated with the mobile mill site. <br /> Prior to setting up a mobile mill facility in the future, the Applicant must receive Division <br /> approval through either a Technical Revision or an Amendment. In addition, the financial <br /> warranty will be adjusted to account for any disturbance associated with the mobile mill. <br /> 2. As noted above, the Applicant has revised the Mining Plan to account for off-site processing <br /> of the ore. Under the revised plan, the Applicant will no longer backfill the trench with <br /> tailings. Therefore, the Mining Plan and Reclamation Plan must be revised to reflect this <br /> change. Please answer the following questions: <br /> a. The Applicant has proposed maximum trench dimensions of 30' (length) x 10' <br /> (width) x 25' (depth). If the Operator is removing all of the material from the site, <br /> what will the maximum dimensions of the trench be? Please note that this will have a <br /> direct effect on the financial warranty calculation. <br /> b. The Applicant has stated there is no need for metal holding structures to hold waste <br /> rock or ore when material is being processed at the Federal Mill. Please explain why <br /> the waste rock or overburden will be removed from the site? <br /> OF'CO< <br /> w_ - +• O.Q . <br /> FQ 'iso <br /> :�w''•<!,901 <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us I <br /> John W.Hickenlooper, Governor I Mike King, Executive Director I Virginia Brannon, Director X876 <br />
