COLORADO LEGACY LAND <br /> SCHWARTZWALDER MINE <br /> Notes: <br /> The following table summarizes relevant information for the Steve Adit(where the mine pool transducer is located)and monitoring wells: <br /> Northing Easting Ground Surface Well Casing Total Depth of Distance to Steve <br /> Location ID Elevation Elevation Well Adit <br /> (feet) (feet) (ft amsl) (ft amsl) (ft bgs) (Linear ft) <br /> SteveAdit 1,732,700.61 3,061,558.53 6,602 N/A N/A N/A <br /> MW13 1,731,272.17 3,059,706.76 7,401.87 7,403.32 500.80 2,338.69 <br /> MW-IS 1,731,742.41 3,061,962.60 6,897.53 6,899.33 1,007.13 1,039.91 <br /> MW-18 1,732,989.50 3,061,365.66 6,575.34 6,576.88 239.9 347.36 <br /> Coordinate values are Colorado State Plane Central Zone (NAD83) Elevations are NADV88.Survey information provided by <br /> Lambert Land Consulting,LLC and were measured on 7/23/2020. <br /> The total depth of the well was obtained from the well construction report. <br /> The distance between the Steve Adit and each MW was calculated using the following formula: d= (xi—X2)2+ (Y1—Y2)2 <br /> The gradient(i)toward the mine pool was calculated using the following formula:i=dl where Ais the difference in head <br /> between the well and the mine pool and dl is the distance between them. <br /> AUGUsr2020 23 AMENDMENT <br />
