Box 177 <br /> Silverton, CO 81433 <br /> contact William B. Goodhard <br /> Resident Manager <br /> Identification of Lands <br /> Surface tailings pond and mine waste dumps located at head of Placer Gulch, San Juan <br /> County, Colorado. Work also to be done for closure of#1 level of Gold Prince Mine. Lands are <br /> included in SGC's Stormwater Permit #COR-040061. See attached general location map and site <br /> map. <br /> Latitude 37 degrees 55 minutes Longitude 107 degrees 36 minutes <br /> Identification of the Waters of the United ed States Potentially Affected <br /> Water flows from above the property into Placer Gulch and joins the Animas River at Animas <br /> Forks. See attached map. <br /> Physical Description of Conditions <br /> The site is a historic mine and mill which operated around the turn of the century. Prior to <br /> the ore being shipped to Animas Forks via aerial tram, it appears that some milling was done on site. <br /> The historic milling activity left a small tailings pond which is partially uncovered and allows for <br /> snowmelt and rain waters to cross, and potentially pass through, the tailings. Waste dumps occurring <br /> on the property and bordering the stream also are not covered. The measured estimate of tailings and <br /> waste rock is 2050 cubic yards. The number one portal has a closure bulkhead in place to prevent <br /> entry; however, it needs to be reinforced to create a water retaining bulkhead. The flow through the <br /> mine workings would then be reduced as the tunnel will no longer be a natural drain for the overlying <br /> area. It is possible that the water could backup and flow into the Sunnyside Mine via old drifts and <br /> raises. This water is of similar or better quality than that projected to flow into the mine pool from <br /> other sources and the quantity is relatively insignificant in comparison. Therefore, no adverse impact <br /> would be anticipated if this were to occur. <br />
