COLORADO <br />Division of Reclamation, <br />Mining and Safety <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />February 25, 2016 <br />To: Brock Bowles <br />From: Jason Musick <br />RE: New Horizon Mine, C-1981-008 <br />REVISED SL -16 RCE Memo <br />The numbers identified in this memo supersede the costs noted in previous memos associated with SL -16. <br />Based on a review by the Division, revised numbers are noted in bold. In addition to the costs associated <br />with the SL -16 bond release application, the required liability for TR -69 was omitted from the initial costs <br />prior to the SL -16 RCE. As such, the total of $9,585.90 associated with TR -69, which was approved after <br />the SL -16 RCE, but before the SL -16 decision , should be added to the required starting liability amount of <br />$5,432,359.95 bringing the SL -16 prior liability amount to $5,441,945.85. <br />The Division updated the reclamation cost estimate with costs updated in October 2014 to reflect 2014 <br />CRG, Means and CDOT rates for the 2015 Midterm Review. This updated estimate total was <br />$5,432,359.95. With the approval of TR -69 which occurred after the 2015 Midterm Review and after the <br />initial SL -16 RCE, but prior to the SL -16 decision, the total is $5,441,945.85. This estimate includes <br />reclamation tasks identified in the permit and includes costs for Technical Revisions 63, 64, 65, 69 and <br />Minor Revision No. 90, which reflect the only revisions that included an increase in liability since the <br />estimate was last updated with the 2013 Bond Release No. 13 (SL -13). SL -13 updated the costs for the <br />entire site. <br />When determining the amount of liability that can be released based on the SL -16 application, the <br />Division updated the cost estimate for the entire mine site based on costs updated with the 2015 Midterm <br />review as noted above and the tasks that could be removed based on work acomplished and requested to <br />be released. Below are a list of tasks that have been revised or removed based on the SL -16 application. <br />Task 002 - The overall length of Cut 96 has been reduced from 3,348' to 1,748' (the length of the area on <br />the Morgan property) volume reduced to 56,971 LCY <br />Task 002B - The overall length of Cut 96 has been reduced from 3,348' to 1,748' (the length of the area <br />on the Morgan property) volume reduced to 48,555 LCY <br />Task 003 - The overall length of Cut 96 has been reduced from 3,348' to 1,748' (the length of the area on <br />the Morgan property) volume reduced to 249,640 LCY <br />Task 009 - The acres to be regraded reduced from 468.60 to 360.8 (less 107.8 ac of Phase 1) <br />Task 021 - Removed Pond 11 dewatering structure <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br />John W.
