To:Jared Ebert <br /> Date: February 27,2018 <br /> Page 6 <br /> Division believes it would be appropriate to set the bond amount at the cost to complete <br /> reclamation assuming mining had occurred and ceased at the end of Phase II. Based on <br /> this assumption,please supply the following information: <br /> a. Please provide an inventory of all mining-related structures to be built or <br /> placed on site such as processing facilities, shops, warehouses, mine offices <br /> and/or trailers,fuel storage tanks/facilities, etc. <br /> b. If LRM intends to dispose of any rubble generated by the demolition of mine <br /> related structures onsite, they will need to identify where this material will be <br /> placed. <br /> c. Please provide the quantity of each item to be demolished. Below is a table <br /> identifying the type of structure to be demolished and the unit of measure the <br /> Division needs to estimate the cost to demolish the structure: <br /> Item Unit of Measure <br /> Building&Similar Structures Cubic Feet(L x W x H)of intact Structure <br /> Process Plants&Mill Building Cubic Feet(L x W x H)of intact Structure <br /> Floors, Slabs&Pavement Square feet(L x W) + estimated thickness <br /> in inches <br /> Footing&Foundations Linear feet+estimated footer width and <br /> height. _ <br /> Walls Square feet(L x H) +estimated thickness <br /> in inches. <br /> Conveyors(portable) Dimensions(L, W,H) _ <br /> Conveyors(non-portable) Cubic Feet(L x Wx H) <br /> Storage tanks(aboveground) Gallons <br /> Storage tanks(underground) Gallons <br /> Powerlines Liner Feet <br /> d. Mining at the site will expose groundwater. Given this, the Division needs to <br /> hold a bond to cover the cost of either backfilling the pit to a point above the <br /> water table or a cost to isolate the pit from groundwater inflow by either <br /> installing a clay liner or slurry wall. Given LRM's choice of the installation of <br /> a clay liner as part of the proposed mining and reclamation plan, please <br /> provide the information necessary to conduct an estimate of the cost for the <br /> installation of the proposed clay liner assuming mining stops at the end of <br /> Phase II. This cost should include the cost for placing and compacting the <br /> clay material in lifts and for quality control measurements to insure the clay <br /> material is installed at the proper compaction specification. Since the <br /> material to construct the liner is found onsite, please also include a cost of <br /> excavating the necessary material. <br /> Response to DRMS Adequacy Review 3 comments T E L E S T O <br />
