Modification to TR-23 Operations and Maintenance Plan for Mayflower Tailings Storage Facility <br /> and 5 Dam <br /> Submitted with TR-29 <br /> Description <br /> In 2014, Climax received approval from DRMS for the Operations and Maintenance Plan for the <br /> Mayflower Tailings Storage Facility (TSF) and 5 Dam (TR-23). The TR-23 plan indicated that Climax will <br /> have 3 leadoffs for deposition of tailings at 5 Dam, and that those leadoffs will be 800ft in length. Climax <br /> determined that the description in TR-23 did not provide the needed flexibility to change the number of <br /> leadoffs or their length throughout the life of mine as the Mayflower TSF grows in height and width over <br /> time. Climax is therefore seeking a change to the descriptions in TR-23 to provide flexibility in the number <br /> and length of leadoffs, as needed, while still maintaining an 800ft beach width from the crest of the dam. <br /> Attached is a replacement page for the Operations and Maintenance Plan for Mayflower Tailings Storage <br /> Facility and 5 Dam revising the language on page 4-6 to reflect these two changes. The attached drawing <br /> titled Mayflower Tailing Delivery System, 2019 5 Dam Line Raise shows the configuration of the leadoffs <br /> starting in the summer of 2019. <br />
