REr -... <br />LGS Nnv 2 5 2014 <br />DIVISION OF RECLAMATION <br />v <br />Exhibit L - Reclamation Costs MINING AND SAFETY <br />Attached are the estimated reclamation costs for the Three Bells Mine, developed to reclaim the <br />site to Developed Water Storage. The costs have divided by mining locations and phases within <br />the Three Bells Mine, including Veldman and Ditullio Phases 1 through 5. The quantities <br />utilized in the reclamation costs have been developed from the actual designs for the slope liners <br />and area fills currently being constructed (Veldman) for planned ( Ditullio). The unit prices <br />presented for the individual items have taken from Engineers Opinions of Costs (EOC) <br />developed for MMM for use in bidding the projects. The EOC was developed based on GEI <br />staff experience in the region on similar projects, and in consultation with local earthmoving <br />contractors. <br />The earthmoving portion of the reclamation within the Veldman Property has been bid out and <br />awarded by MMM with construction slated to begin in April 2014. However, as a result of the <br />high runoff on the Cache la Poudre River, the project was delayed until August to September <br />2014 (based on site conditions). Earthmoving reclamation within the Ditullio portion of the site <br />will be conducted concurrently with mining. MMM plans to fill in Phase 5 as mining <br />commences within Phase 3. Phases 1, 3, and 4 will be constructed from overburden material that <br />has been stockpiled onsite or excavated during stripping operations. Phase 2 will be utilized for <br />wash fines during the Ditullio mining operations, and will be reclaimed to an unlined open water <br />pond. <br />The vegetation acreage has been estimated based on the areas within the permit boundary outside <br />of the proposed Developed Water Storage (or unlined open water pond), as water levels within <br />these areas will fluctuate (based on storage needs) and do not require vegetation. <br />�r; Ma4jr) <br />nn r <br />nQ rim G <br />
