Goodhard <br /> Resident Manager <br /> Identification of Lands <br /> Surface waste dump at the American Tunnel site of Sunnyside Gold Corporation(SGC). Lands <br /> are included within Mined Land Reclamation Permit #M-77-378 boundary. Lands are included in <br /> SGC's Stormwater Permit #COR-040052 identified as American Tunnel. Lands are located at <br /> Gladstone, San Juan County, Colorado.

Cement Creek flows into <br /> the Animas River at Silverton Colorado. See attached map. <br /> Pbysical Description of Conditions <br /> The mine waste dump and underlying tailings, located on the north side of the South Fork of <br /> Cement Creek,was estimated to total approximately 80,000 cubic yards prior to 1994 removal work. <br /> The dump is comprised of waste generated during the mining at Sunnyside and underlying the waste <br /> dump is an old historic tailings pond from another facility. Due to the proximity to the creek and <br /> groundwater, SGC believes that the underlying tailings should be removed and the mine waste <br /> material removed or protected from percolation of rain and snow waters. This project is an <br /> unanticipated extension of the tailings removal action near the American Tunnel, first begun in 1991, <br /> on the south side of the South Fork of Cement Creek. See attached pre project monitoring and site <br /> characterization information. <br />
