Pride of the West Tailings Page 2 Site Loading Estimate (cont.) its mitigation project at this site will remove any specific percentage of metals loading from this site: the loading estimate contained herein does not form the basis of an enforceable permit obligation. Description of Project Sunnyside Gold Corporation(SGC)will provide sediment catchments below the tailings to minimize sediment transport to the river during excavation. The tailings would be removed from contact with flowing water and stormwater and placed in the Mined Land Reclamation permitted tailings pond on the property. The excavated area would then be revegetated. No additional reclamation work will be done on the permitted facility. The catchment traps will be removed, the site regraded, soil amendments added, seeded and mulched. Work Plan 1)Build catchments. 2)Relocate tailings. 3)Remove catchments and regrade area. 4) Add soil amendments as needed, seed and mulch. n Removal and consolidation of these tailings will remove the materials from exposure to groundwater seeps and severe the direct connection to the Animas River. This will prevent direct contact with flowing water and reduce the risk for impact to the Animas River and Cunningham Creek. Monitoring Due to the close proximity and high flow conditions which occur in the Animas River, no monitoring is required for this project. Repo Notification will occur at the start of project with a final report to be submitted after completion of project. The final report will include cubic yards moved, final disposition of material and soil amendments used. Monitoring reports will be included with the annual seep and spring study and sent to both Water Quality Control Division and the Division of Minerals and Geology. Budget SGC will fund this program unless the property owner chooses to contribute.
