mediation Plan: Remediating Party: contact Surface Mill Tailings at Eureka Sunnyside Gold Corporation )` +v '. f ] MG P.O. Box 177 Silverton, CO 81433 William B. Goodhard Resident Manager Identification of Lands Historic surface tailings disturbance at abandoned townsite of Eureka, located in San Juan County Colorado. See attached general location map and site map. Latitude 37 degrees 53 minutes Longitude 107 degrees 34 minutes Identification of the Waters of the United States Potentially Affected Animas River between confluence of Eureka Creek and confluence of Minnie Gulch. See attached map. Physical Description of Conditions The southern half of the old townsite of Eureka may have been impacted by milling operations in the early part of the century. The historic tailings are confined to two large ponds as well as smaller scattered locations throughout the southern half of the townsite. The total measured estimated volume is 65,500 cubic yards. These tailings are exposed to rain waters, snow melt and during high flow to the Animas River and the South Fork of the Animas River. As a result, there may be an impact on the Animas River. The area also has an adverse visual impact. Description of Project Sunnyside Gold Corporation (SGC) will provide sediment catchment traps below the tailings, then remove tailings, add high pH material to stabilize pH near neutral and redeposit tailings at the Mayflower Tailings Pond #4. Under Sunnyside Gold Corporation's MLR Permit M -77 -378 this material can be consolidated into Tailings Pond #4. The tailings would then be capped with growth media and planted as part of the approved reclamation plan at Tailings Pond #4. Any material caught in the catchment traps will also be removed. This project may require a 404 permit from the Army Corps of Engineers due to work occurring in a flood plain. This plan is also subject to notification requirements for disturbance of Historical Mining Sites to the board of the San Juan County
