12. Exhibit L - Reclamation Costs <br />Attached are the estimated reclamation costs for the Three Bells Mine, developed to reclaim <br />the site to Developed Water Storage. The costs have divided by mining locations and phases <br />within the Three Bells Mine, including Veldman and Ditullio Phases/p nds 1 through 5. The <br />quantities utilized in the reclamation costs have been developed from the actual designs for <br />the slope liners and area fills currently being constructed (Veldman) for planned ( Ditullio). <br />The unit prices presented for the individual items have taken from Engineers Opinions of <br />Costs (EOC) developed for N4N4MMM for use in bidding the projects. The EOC was <br />developed based on GEI staff experience in the region on similar projects, and in <br />consultation with local earthmoving contractors. <br />The eaFthmeving poi4ion of the reclamation within the Veldman PropeAy has been bid out <br />and awarded b MMMA,ith constmetion slated to begin inApril 2014. Howe er&s a result <br />ef the high naneff en the Gaehe !a Peudre River, the pr-ejeetwas delayed until August-te�- <br />September- 2014 (based an site eenditions).The reclamation slope for the Veldman Property <br />has been completed, and the estimated costs listed in Table 5 reflect the remaining portion of <br />the reclamation plan. Earthmoving reclamation within the Ditullio portion of the site will be <br />conducted concurrently with mining. N4N4N4MM }glans to filled in Phase 5 as mining <br />commenceds within Phase 3. Phases 1, 3, and 4 will be constructed from overburden <br />material that has been stockpiled onsite or excavated during stripping operations. Phase 2 <br />will be utilized for wash fines during the Ditullio mining operations, and will be feelaimed to <br />an unlined openwatef p backfilled. <br />The vegetation acreage has been estimated based on the areas within the permit boundary <br />outside of the proposed Developed Water Storage (or unlined open water pond), as water <br />levels within these areas will fluctuate (based on storage needs) and do not require <br />vegetation. <br />The reclamation costs are summarized in Table 56 and 7: <br />GEI Consultants, Inc. 32 Jane January 20145 <br />Three Bells Mine Reclamation Permit Amendment <br />
