The work was <br />done in accordance with our agreement for geotechnical engineering services to you, dated <br />June 17, 2003. <br />Site Conditions: We visited the site on June 17, 2003 to observe the topography and exposed <br />hydraulic mined slopes. The proposed mining operation will encompass an area of about 10 <br />acres and is located immediately west of Fairplay, Colorado. The site is bordered by the <br />South Platte River to the south, Highway 9 to the north, Town of Fairplay to the east, and <br />vacant land to the west. The site has been previously hydraulically mined and generally slopes <br />down towards the south. The slopes are typically moderately to very steep below Highway 9 <br />and become less steep near the river. Several bluffs up to about 25 feet in height exist on the <br />steep slopes. The tower portion of the site is less steep and characterized by large piles of <br />cobbles and boulders left over from the hydraulic mining and possible dredging operations. <br />Several man-made channels, remnant from the mining operation exist through the piles. <br />Vegetation consists of native grasses, sagebrush with scattered pine trees. No water seepage <br />was observed on the steep slopes or in the less steep portions of the site. <br />Glenwood Springs 970-945.7988 Parker 303-841.7119 Colorado Springs 719.633.5562 <br />
